Specifications


	Maximum Discharge Flow		The maximum flow the pump is designed to generate. This value is dependent on the system or pressure head the pump must enter.
	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.

	Maximum Discharge Pressure		The maximum pressure the pump is designed to generate.
	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.

	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.

	Ground Water		Untreated water that is found on or collects freely on the ground.
	High Viscosity Fluids		Thick liquid materials with a high resistance to flow.
	Liquids		All materials in the liquid state of matter - substances which exhibit a characteristic readiness to flow.
	Lubricants		A substance, such as grease or oil that reduces friction when applied as a surface coating to moving parts.
	Oil		Any of many mineral, vegetable, or synthetic substances or animal and vegetable fats that are generally slippery, combustible, viscous, liquid or liquefiable at room temperatures, soluble in various organic solvents (such as ether) but not in water, and used in a great variety of products, especially lubricants and fuels.
	Potable Water		Water that is considered safe and fit for human consumption, culinary and domestic purposes and meets the requirements of the health authority having jurisdiction.

Pump Features


	Pump Features
	Your choices are...
	Adjustable Speed		Adjustable speed pumps can operate at speeds that can be selected by an operator.
	Belt Driven		The pumps shaft is driven by a belt.
	Close Coupled		Close-coupled pumps have the pump end mounted directly on the motor shaft.
	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.
	End / Bottom Suction		End suction pumps have centerline suction and discharge.
	Horizontal Orientation		Pump stator / rotor assembly is lying horizontally. Media is pumped horizontally through the pump.
	Magnetic Drive		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.
	Non-clog		Non-clog pumps are configured to pump sticky or stringy materials that would clog other types of pumps.
	Portable		The pump is packaged for easy transportation.
	Run Dry Capable		Pump can operate with no pumped fluid or external lubrication for an extended period of time with no damage.
	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.
	Vertical Orientation		Pump stator / rotor assembly is vertically upright. Media is pumped vertically through the pump.
	Other		Other unlisted, specialized, or proprietary pump feature.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Primary Material of Construction
	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.
	Cast Iron		The term "cast iron" refers not to a single material, but to a family of materials whose major constituent is iron, with important trace amounts of carbon and silicon. Cast irons are natural composite materials whose properties are determined by their microstructures - the stable and metastable phases formed during solidification or subsequent heat treatment. The major microstructural constituents of cast irons are: the chemical and morphological forms taken by carbon, and the continuous metal matrix in which the carbon and/or carbide are dispersed.
	Stainless Steel		Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings.
	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.
	Other		Other unlisted, specialized, or proprietary material.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
