Pump Type



	Your choices are...
	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.
	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 used 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.
	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.
	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.
	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.
	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.
	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
	Other		Other unlisted or specialized pumps.

	Number of Pumps in Assembly		Quantity of pumps located in or on a pump assembly. This does not include stages. For example, a lift station may have several pumps located within. Another example is a piston pump that has one or more pistons. Each piston would count as a pump.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Pump Features


	Pump Features
	Your choices are...
	Adjustable Speed		Adjustable speed pumps can operate at speeds that can be selected by an operator.
	Continuous Duty		The pump is rated to run continuously; it can maintain performance specifications at 100% duty cycle.
	Corrosion Resistant		The pump is constructed from corrosion resistant materials, such as stainless steel.
	Explosion Proof		Explosion proof pumps are designed to prevent internal or external explosions by enclosing parts that could cause ignition of the transfer media or the surrounding atmosphere. Additionally, they are designed to prevent internal explosions from affecting the surrounding atmosphere and vice versa.
	Hygienic		The pump is constructed from hygienic materials, and is fully sealed to eliminate leakage and contamination of pumped materials.
	Multi-stage		Compressed fluid goes from initial stage to successive chambers or stages of pressurization; used to generate higher-pressure levels than are possible with single stage pumping.
	Sanitary		The pump is specifically designed to meet the strict guidelines established for sanitary process applications. Classifications and ratings may include FDA, USDA, and 3-A.
	Self-priming		Priming is the introduction of fluid into the pumping chamber to create the pressure differential to begin pumping at rated service. Self-priming pumps are constructed so that they can create and maintain a sufficient vacuum level to draw fluid into the inlet with no external assistance.
