More Specs




   Inlet Size
 
     Size of the pump inlet connection.
 
   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.
   Discharge Size
 
     Size of the pump discharge or outlet connection.
 
   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.
   Media Temperature
 
     Temperature of the media being pumped.
 
   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.
   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. 
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   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.
 
   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.
 
   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.
