Plunger Pumps

Cat Pumps

Cat plunger pumps have a flow range of 0.13 to 240 GPM (0.49 to 908 LPM) and a pressure range of 100 to 10,000 PSI (6.9 BAR to 689 BAR). They come in materials like brass, nickel aluminum, 304, 316, and duplex stainless steel. They can be driven by motors, gasoline or diesel engines, hydraulic and pneumatic systems. The average seal life is approximately 8,000 hours, eight times longer than similar pumps in the industry, making them ideal for 24/7 industrial processes.
