Housing Material

	Your choices are...
	Aluminum		A bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
	Brass / Bronze		Brass comes with good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability. Sintered bronze is a porous material, which can be impregnated with oil, graphite or PTFE. Not suitable for heavily loaded applications but useful where lubrication is inconvenient.

Type Of Pump

	Your choices are...
	Piston / Plunger Pumps		Piston pumps and plunger pumps are reciprocating pumps using a plunger or piston to move the media through a cylindrical chamber. They use steam power drives, pneumatic drives, hydraulic drives, or electric drives to actuate the piston or plunger.  Some piston pumps and plunger pumps are also referred to as well service or high viscosity pumps.
	Pool Pumps		Pumps that are used for circulation and filtration of pool water.  Typically supplied with features like filters and strainers.
	Positive Displacement Pumps		Positive displacement pumps use a mechanical force to push liquid through and out of the pump. Rotating gears, reciprocating pistons or diaphragms are the most common types of positive displacement pumps. These pumps are suitable for higher viscosity liquids or when pressure requirements are high.
	Progressing Cavity Pumps		Progressing cavity pumps are a type of rotary positive displacement pump designed to transfer fluid or media with suspended solids or slurries from the suction side of the pump to the discharge side of the pump from storage tanks or through pipelines. Advantages of progressing cavity pumps include moving viscous media at lower velocities.
	Propeller Pumps		Propeller pumps are generally high-speed but with low heads. They can be quite large, measuring over twelve feet in diameter and moving over 50,000 gallons per minute. Some have adjustable-pitch blades. Propeller pumps are designed for pumping large volumes at low head.
	Radial Flow Pumps		A centrifugal pump uses diffuser vanes to transform the velocity head into pressure head. Commonly called a ‘‘turbine pump."
	Ram Pumps		Hydraulic ram pumps use the energy of large amounts of water falling a small height to lift a small amount of that water to a much greater height. In this way, water from a spring or stream in a valley can be pumped to a village or irrigation scheme on the hillside.  In general, a ram pump can pump approximately one tenth of the received water volume to a height ten times greater than the intake. A hydraulic ram pump is useful where the water source flows constantly and the usable fall from the water source to the pump location is at least 3 ft.
	Reciprocating Pumps		Reciprocating pumps move liquids by a plunger or piston that travels back and forth inside a cylinder. Regulating the speed of the drive controls flow. There is no head loss by throttling as in a centrifugal pump. These pumps are often used for high or very high pressures. Also often used as metering pumps because of constancy of flow rate. Adjusting the RPM of the driver can easily change the flow rate.
	Refueling Pumps		Fuel handling pumps used for the refueling of machinery, automobiles, aircraft, watercrafts or other equipment.
	Rotary Lobe Pumps		Rotary lobe pumps are positive displacement pumps that use rotating lobes to direct flow. Lobe pumps are similar to gear pumps in operation in that fluid flows around the interior of the casing. Rotary lobe pumps are frequently used in food applications because they can process solids without damaging the product. Since the lobes do not contact each other, these pumps can handle products of a larger particle size and are ideal for pushing through low viscosity media.
	Rotary Vane Pumps		Rotary vane pumps are liquid handling, positive displacement pumps that contain vanes in a cavity that rotates to create the flow.
	Sampling Pumps		Pumps used for extracting a small amount media from its main body for analysis.
	Sanitary Pumps		Sanitary pumps are made of materials and constructed in design so that they are readily cleanable. They are widely used in the dairy, food processing, pharmaceutical, cosmetic, and other industries where cleanliness is a concern.
	Screw Pumps		Screw pumps are rotary, positive displacement pumps that can have one or more screws to transfer high- or low- viscosity fluids along an axis.
	Self-Priming Pump		Self-priming pumps create and maintain a sufficient vacuum level to draw fluid with no external assistance.
	Siphon Pumps		Siphon pumps are typically manually operated and self-powered once begun. The pump is used to begin the flow of fluid. Flow and gravity then draw fluid from one container to another.
	Split Case Pumps		Split case pumps are larger pumps that are used for high flow applications. "Split case" describes the pump housing design.  The case around the impeller or pumping mechanism is comprised of two parts that bolt or assemble together. These pumps come in vertical and horizontal configurations.
	Submersible Pumps		These pumps are mounted in the tank with the solution. The motor is normally contained in an oil filled cavity that is protected for contact with the liquid by a lip or mechanical seal. They can be designed to pump large solids or grind solids to smaller sizes, transfer wastewater at large flow rates or high pressures, or just pick up water off the floor or the bottom of a tank.
	Sump Pumps		A sump pump is an automatic water pump installed in a contained compartment to remove unwanted water build-up that threatens to encroach on living or equipment space.
	Syringe Pumps		Infusion or withdrawal syringe pumps provide high pressure and high accuracy for applications such as high performance liquid chromatography (HPLC). Used to deliver precise amounts of fluid at specific time intervals
	Testing / Calibration Pumps		Pumps that are designed specifically for testing and or calibration purposes.
	Trash Pumps		Portable pump and power source typically for dewatering applications. Can handle media with high solids content.
	Triplex Pumps		A positive-displacement reciprocating pump that is configured with three plungers. Triplex pumps are the most common configuration of pump used in both drilling and well service operations. Pumps used in well service activities generally are capable of handling a wide range of fluid types, including corrosive fluids, abrasive fluids and slurries containing relatively large particulates.
	Turbine Pumps		A centrifugal pump uses diffuser vanes to transform the velocity head into pressure head. These pumps have one or more stages, each consisting of an impeller on a vertical shaft, surrounded by stationary and usually symmetrical guide vanes. Combines the energy-imparting characteristics of axial-flow and propeller pumps.
	Utility Pumps		Pumps for the general transfer of fluids.
	Vortex Impeller Pumps		With a vortex pump, flow through the unit is produced not by the actual impeller, but rather by a rotating vortex created by the impeller. Because the pumping action is created by the vortex, particles in the liquid do not come in contact with the impeller itself.
	Wastewater Treatment Pumps		All types of pumps used in the process of wastewater treatment.
	Water Jetting Pumps		These units typically operate at 10,000 to 40,000 psi and are used in surface preparation; internal cleaning of pipes and heat exchangers, concrete removal (hydro demolition); and as a cutting alternative to saw blades and laser cutting machines for parts fabrication.
	Water Supply Pumps		All types of pumps used for the supply of potable water.
	Water Treatment Pumps		All types of pumps used in the process of water treatment.
	Shallow Well Pumps		A pump located above ground to lift water out of the ground through a suction pipe. Limit is a lift of 33.9 feet, at sea level.
	Deep Well Pumps		A submersible or deep well jet pump used to force water upward from a pumping element below the water level. Not restricted by suction lift limitations.
	Well Stimulation Pumps		Operations used to increase the production of an oil well. Treatments that are frequently used to rejuvenate old of poorly producing wells
	Other		Other unlisted or specialized pumps.
	Agitator Pumps		For industrial, mining, milling, and power plants or anywhere slurry solids accumulate. These pumps agitate the media around the inlet. Since water always flows to the path of least resistance, a pump without mechanical agitation will only pump the water, leaving the solids behind to accumulate around your pump intake, and eventually starving the pump by blocking the intake. Agitator pumps deliver kinetic energy to slurry solids surrounding the pump intake, re-suspending them into a fluid state. These solids, which would have otherwise buried and starved the pump of liquid, are pulled into the pump and pushed on through the discharge, keeping the intake clear and free of slurry accumulation.
	Axial Flow Pumps		A rotary pump that develops head mostly by the propelling or lifting action of the vanes on water, commonly referred to as a propeller pump.
	Bellows Pumps		The bellows pump operates on the positive displacement principle. The rotation of a motor or compressing of the bellows causes the bellows to compress for one half of the rotation, causing the pump to dispense liquid into the discharge line. During the other half of the rotation, the motion of the crank mechanism causes the bellows to expand, drawing liquid from the suction line into the bellows module. The pump uses two valves to control the flow of the liquid through the pump. Discharge pressure is maintained over the entire flow range of the pump.
	Bilge / Ballast Pumps		Pumps used onboard boats and ships to remove water from the bilge or to load or remove water for ballast.
	Bladder Pumps		Bladder pumps consist of a flexible, squeezable bladder encased in a rigid outer casing. They are low-flow pneumatic devices used for sampling applications. Bladder pumps are available in a range of sizes, materials, and capabilities. This includes models for deep wells, narrow or obstructed casings, and small-volume pumps for low-yield wells. When low-flow pumping rates are used, these pumps consistently collect high-quality, uniform samples. Bladder pumps are EPA-accepted for low-flow sampling.
	Boiler Feed Pumps		Pumps feed the condensate back into a boiler for reheating and reuse. These pumps close the boiler/steam/condensate loop by returning hot condensate back to the system. This takes advantage of valuable BTUs, which would otherwise go to waste.
	Booster Pumps		A pump used to increase pressure in a pressure line, or to pull from a storage tank and pressurize a system.
	Borehole Pumps		Borehole pumps to be installed into wells. These can either be inclined or vertical wells. A borehole pump is a fully sealed unit. It can be fully submerged or operate in an atmosphere of potentially explosive gases. Borehole pumps range in size from a few cubic meters per hour, with as little as five meters hydraulic head, to many hundreds of cubic meters per hour, with hydraulic heads ranging up to several hundred meters. Borehole pumps are employed where water in a site is free draining to a single point within the site and an extraction flow rate of above a few cubic meters per hour is required.
	Canned Motor Pumps		The canned motor pump is a seal-less pump. The electric motor is encapsulated in a can that isolates the rotor and process liquid from the stator. With a canned motor pump, the inner rotor is directly connected to the pump impeller, which unitizes the pump and motor. This results in a compact pumping package.
	Cantilever Pumps		Motor and seals are kept away from the pumped media. The pump has an elongated drive shaft and is submerged in the media. They have no submerged seals, bearings, bushings, or suction check valves. The cantilever or overhung shaft is supported by heavy-duty ball bearings that are located above the pumped liquid.
	Centrifugal Pumps		Centrifugal pumps use a rotating impeller to add velocity to the liquid being pumped. Within the pump, the velocity of the liquid is generated by centrifugal force. The velocity of the solution is converted with internal restrictions within the pump into pressure. This type of pump is used for liquids that are water-like in viscosity and when quantities of flow are large compared to the pressure requirements.
	Circulation Pumps		Pumps that are used to keep media circulating through the distribution or process system.
	Condensate Pumps		Pumps that transport or collect and transport condensate collected from a steam system back into the system for reheating and reuse. These pumps close the boiler/steam/condensate loop by returning hot condensate back to the system. This takes advantage of valuable BTUs, which would otherwise go to waste. Or pumps for removal of unwanted condensate from an HVAC or appliance collection pan.
	Dewatering Pumps		Designed for clear water applications (agricultural, industrial, and residential). As a general rule, dewatering pumps are limited to a 10% solids concentration and a solids size of 1/4 the diameter of the suction inlet. For applications requiring greater solids handling capability, trash pumps should be used.
	Diaphragm Pumps		Diaphragm pumps are the most common industrial PD pumps. They are sometimes referred to as a membrane pump. A typical configuration consists of a single diaphragm, a chamber, and suction and discharge check valves to prevent backflow. The piston can either be directly coupled to the diaphragm or can force a hydraulic oil to drive the diaphragm. Variations include bellows-type diaphragms, hydraulically actuated double diaphragms, and air-operated, reciprocating double-diaphragms.
	Dosing Pumps		Dosing pumps are low-volume fluid pumps with controllable discharge rates to inject chemical additives into the mixing or pumping system. They are frequently used to efficiently inject difficult-to-mix fluids into batch-tank systems because of their low volume.
	Double Diaphragm Pumps		Double diaphragm pumps are displacement pumps that compress fluid by decreasing the volume of a chamber containing the fluid. Two diaphragms are mechanically, hydraulically, or pneumatically oscillated to displace the liquid or gas. The chamber is divided with one side using hydraulic fluid, air, or a motorized drive to move the diaphragm. The media is pulsed through the pump without contacting the actuating media.  Double diaphragm pumps are often a component in a complete fluid transfer system where a switch or valve is used to control the flow of the media continuously or on demand.
	Drum Pumps		Drum pumps are designed to transport or dispense the contents of drums, pails, or tanks. Pumps are driven by a variety of methods including hand operated, electric, pneumatic, and hydraulic driven motors. Explosive environments or flammable fluids may require an intrinsically safe actuation method.
	Ejector Pumps		Ejector pumps are sewage handling pumps that are required when wastewater cannot flow to its destination by means of gravity at a velocity of at least 2 ft./s. There are two basic types of ejector pumps. One is the vertical suspended type where the motor is mounted on the cover of the basin, supported by its shaft connected to the pump housing inside the basin. The second type is the close-coupled submersible, where the motor is connected directly to the pump housing and impeller by a short shaft and is submerged completely inside the basin.
	Fire Service Pumps		Pumps that are used for the supply of water/media for firefighting equipment.
	Flexible Impeller Pumps		Flexible impeller pumps contain an elastomeric impeller that traps fluid between blades and sweeps it through the pump housing. These low-cost utility pumps are ideal for general transfer.
	Fountain Pumps		Pumps that are designed to supply flow to fountains. Fountains are used for esthetic purposes, as well as aeration in residential, commercial, and industrial applications.
	Gear Pumps		Gear pumps are positive displacement rotary pumps used to transport high-pressure and high-volume flows. They function through the use of two or more internal gears that create vacuum pressure, propelling the fluid media. Gear pumps provide a comparably continuous, non-pulsating flow in relation to diaphragm pumps or peristaltic pumps. For this reason, gear pumps may be preferred in a number of applications from laboratory to petrochemical and marine applications, and processes involving hydraulic presses and dry pit steam power.
	Grinder Pumps		A mechanical device that shreds solids and raises sewage to a higher elevation through pressure sewers. A sewage grinder pump will discharge a finely ground slurry into a small diameter pressure pipe. In a low-pressure sewer system (LPSS) the piping downstream of the grinder pump will typically be under low pressure, 60psi or less.
	Hand / Foot Pumps		Hand pumps are manually operated pumps that can be driven by hand or foot via a handle or lever. This manual external force actuates an internal mechanism, which increases pressure for moving fluids such as gas, chemicals, or water.
	Hydraulic Pumps		Hydraulic pumps deliver high-pressure fluid flow to the pump outlet. They use gears, vanes, pistons or other devices to pressurize fluid or power hydraulic pumps. A hydraulic pump, when powered by pressurized fluid, can rotate in a reverse direction and act as a motor.
	Immersible Pumps		A pump in which the pumping mechanism only can be subjected to immersion in the media. Motors are kept away from media by a sealed barrier.
	Injection Pumps		Any pump used to inject fluid into the reservoir or production system. Injection pumps vary in volume and pressure capacity, from the large injection pumps used in water-injection wells, too much smaller low-volume injection pumps used in continuous scale-inhibitor treatments.
	Jet Pumps		A surface-mounted centrifugal pump that uses an "ejector” device to augment its suction capacity. The ejector may be down in the well, to assist the pump in overcoming the limitations of suction. (Some water is diverted back down the well, causing an increase in energy use.)
	Lift Stations		A pump station that contains pumps, valves and electrical equipment necessary to pump water or wastewater.
	Macerator Pumps		Macerator pumps are designed to empty holding tanks of sewage. They typically include a bronze cutter to grind waste down to a small particle size.
	Magnetic Drive Pumps		Magnetic drive pumps are operated using a magnetic or electromagnetic drive. They are ideally suited to a variety of applications including laboratory, production line, chemical processing, general transfer utility, as well as OEM applications.
	Metering Pumps		Metering pumps are positive displacement chemical dosing devices with the ability to vary capacity manually or automatically, as process conditions require. Metering pumps feature a high level of repetitive accuracy and are capable of pumping a wide range of chemicals including acids, bases, corrosives, or viscous liquids and slurries.
	Micro Pumps		Micro pumps are essential for moving fluids in miniaturized systems. The working principal of a typical micro pump involves interaction of a flexible structure with the working fluid. The flexible structure is deformed using some actuation technique (e.g. piezoelectric or electrostatic actuation) and the deformation provides a positive displacement action for moving the working fluid.
	Mixed Flow Pumps		A centrifugal pump in which the pressure is developed partly by centrifugal force and partly by the lifting action of the impellers on the water.
	Mixing Pumps		Mixing pumps are used for mixing applications within the contents of a drum, tank or other container.
	Mud Pumps		A large, reciprocating pump used to circulate the mud on a drilling rig. A typical mud pump is a double- or triple-acting, two- or three-cylinder piston pump whose pistons travel in replaceable liners and are driven by a crankshaft actuated by an engine. A mud pump also is called a slush pump.
	Peristaltic Pumps		Peristaltic pumps are rotary pumps using a turning mechanism to move media through a tube. The tube is compressed at a number of points in contact with the rollers or shoes. The media is moved through the tube with each rotating motion. The individual components of peristaltic pumps include a pump head, drive, and tubing. Peristaltic pumps are also referred to as flexible member pumps, flexible tube pumps, dispensing pumps, or dosing pumps.
