Positive Displacement Pumps

Positive Displacement Pumps

We offer the widest selection of pumps and fluid handling instruments in the industry. Plus we can special order virtually any pump your application may require!

Air-Powered 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 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.

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.

Hose Pumps offer a high-capacity, high-pressure option that operate on the peristaltic hose pump technology. Product is available in both dry-running and lubricated designs.

Pressure Washers/Plunger Pumps combine a high-pressure pump with spray accessories to provide a self-contained high-pressure washing system.

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.

Roller Pumps have spinning rollers that create a vacuum to draw in liquid to carry to the outlet port. They provide no metal to metal contact; fluid contacts only the rollers or pump housing.

Rotary Lobe Pumps are excellent for CIP/SIP applications where cleanability of the machine needs to be maintained. They also are ideal for flows at higher pressures.

Rotary Vane Pumps are similar to flexible impeller pumps, except that they have a rigid impeller made of carbon/graphite. Pumps provide high-pressure, low-shear pumping.
