Reciprocating Pumps
Reciprocating pumps move fluid by the back-and-forth motion of a plunger or piston inside a cylinder. They develop high pressure at relatively low flow rates, making them the standard choice for water injection, crude oil transfer, chemical injection, and well servicing operations in the oilfield.
Proxima supplies reciprocating pumps through Power Flow International Sales, representing Gardner Denver, Kerr Pumps, and Scot Industries.
Oilfield Applications
- Crude oil transfer and boosting
- Water injection for pressure maintenance
- Well servicing and workover fluid pumping
- Chemical injection at high pressure
- Produced water disposal
- Pipeline hydrotesting

Frequently Asked Questions
Q: What is the difference between a duplex and triplex pump?
A duplex pump has two cylinders; a triplex has three. Triplex pumps produce smoother, more uniform flow and are the standard for higher-pressure applications. Duplex pumps are simpler and lower cost for moderate-pressure service.
Q: Can Proxima supply a complete pump package — pump, engine, skid?
Yes. Power Flow engineers complete reciprocating pump packages to customer specifications, including pump, prime mover, skid, piping, instrumentation, and documentation. Specify your flow rate, pressure, fluid, and power source.
Q: What spare parts should be stocked for a reciprocating pump?
Expendable parts — valves, seats, plungers, packing, and fluid end components — are the most frequently replaced items. Proxima recommends a first-fill spare parts kit with every pump order.
