What is a Simplex Pump?

A simplex is the designation of a reciprocating pump which utilizes a single drive rod design.

What is a Single Action Pump?

Single Action (Pump): A reciprocating pump design that produces a pressure differential across the pump in only one direction of drive rod motion.

What is a Dual-Acting Pump?

A reciprocating pump design which produces a pressure differential across the pump on both the in and out stroke of each drive rod.

What is a Duplex Pump?

A designation of a reciprocating pump that uses two drive rods. Duplex pumps are common in both single and dual acting designs.

What is a Triplex Pump?
