Cole-Parmer offers the widest selection of pumps and fluid handling instruments in the industry. Plus we can special order virtually any pump your application may require! Call our Application Specialists for expert advice on selecting the best pump for your system.
Hand Pumps are economical and compact—ideal for general liquid transfer in the field or in hazardous locations.
Air-Operated Pumps contain no heat-generating electrical components, allowing safe, explosion-proof operation in hazardous areas. Pumps require input from a compressed-air source; available in bellows and diaphragm models.
Bellows Pumps move fluid or gases through the cavity created by reciprocating bellows coupled to a driving rod.
Diaphragm Pumps pulse one or two flexible diaphragms to gently displace liquid; check valves control direction of fluid flow.
Flexible Impeller Pumps contain elastomeric impeller that traps fluid between blades and sweeps it through the pump housing. These low-cost utility pumps are ideal for general transfer.
Rotary Vane Pumps are similar to flexible impeller pumps, except that they have a rigid impeller made of carbon/graphite. They provide high-pressure, low-shear pumping.
Flexible Liner Pumps gently push fluid between the outer surface of a flexible liner and the inner surface of a rotating body block; can pump 20% soft solids.
PTFE Nutating Disc Pumps use a rotating wobble plate and cavity for mechanically simple and reliable pumping. Ideal for transfer where purity and chemical compatibility are critical.
Progressing Cavity Pumps (rotary screw pumps) force high-viscosity (up to 20,000 cp) and particulate-laden fluids through the cavity between the screw-style rotor and stator.
Plunger Pumps achieve high pressures with metallic piston/cavity and valves. Use for injection and washing applications.
Pressure Washers combine a high pressure pump with appropriate spray accessories to give you a self-contained high-pressure washing system.
Spray Nozzles efficiently break up bulk fluid into smaller particles and distribute these evenly and predictably. Used in a variety of applications form dust control to washing.
