Triplex High Pressure Positive Displacement Piston And Plunger Pumps


Cat Pumps offers an extensive line of industrial triplex high-pressure piston and plunger pumps. Our precision triplex design assures high energy-efficiency, a smooth low-pulsation flow and exceptionally long life.

Our high pressure triplex piston pumps use a dynamic seal that moves through a cylinder to deliver pressures up to 1500 psi and flows up to 60 gpm. Cat Pumps' triplex piston pumps feature our patented sleeved-piston rod and UNIFLOW design for a smooth flow, strong suction capabilities and easy wet-end service.

Our reciprocating, positive displacement, high pressure triplex plunger pumps feature static Lo-Pressure and Hi-Pressure seals supported by adapters or seal cases and deliver higher pressures up to 10,000 psi and flows up to 240 gpm. Cat Pumps' triplex plunger pumps offer many drive options and liquid-end construction in brass, nickel aluminum bronze, 316SS and Duplex SS for compatibility with many applications. Our exclusive seal design and concentric solid ceramic plungers provide extended seal life and low maintenance.

Both our triplex piston and plunger pumps feature heavy-duty crankshafts, high-strength connecting rods, dual bearings and forged brass or stainless steel manifold heads for optimum performance, exceptional life and a high return on your investment.
