Positive displacement pumps
Positive displacement pumps offer reliable, durable, and precise fluid transfer by trapping a fixed amount of fluid inside a chamber and then transferring at a specific flow rate via pistons, gears, or diaphragms. This method of transfer makes positive displacement pumps ideal for the precise metering of chemicals and high-pressure, high-flow industrial applications. These applications include the oil & gas, concrete, asphalt, chemical & petrochemical processing, and water & wastewater industries.
The two main categories of positive displacement pumps are rotary and reciprocating, which refer to the method by which fluid is transferred.

IPEC’s line of positive displacement pumps is designed for flow rate consistency with high-pressure, high-viscosity fluids
We offer rotary and reciprocating positive displacement pumps to help optimize fluid handling efficiency and productivity in the harshest industrial environments. Our Milton Roy positive displacement pumps provide leak-resistant protection and are API 675 compliant. Modular engineering helps reduce your industrial footprint and makes it easy to configure and install these pumps to suit any application. Plus, simplified maintenance processes help maximize uptime to drive growth and profitability.
