CAT Pump Model 650 Plunger Pump 7 GPM @ 1000 RPM, Pressure 100-3000 PSI

This triplex (three plunger rods) positive displacement, reciprocating plunger pump is constructed with a nickel aluminum bronze manifold, 304 stainless steel valve assemblies, solid ceramic plungers and standard NBR (Buna-N) seals and O-rings.


• Triplex plunger design ensures high efficiency and low pulsation.
• V-packings and low-pressure seals are completely lubricated and cooled by pumped liquid, greatly increasing service life.
• Direct-drive option offers a compact foot-print for electric motors with a NEMA or IEC frame, or SAE hydraulic motors with a bell housing/flexible coupler assembly.
• Belt-driven option provides precision flow setting.
