Description

The Cat Pumps Model 270 is a legendary 3-frame triplex piston pump. While the industry has shifted largely toward plunger pumps (like the 310), the 270 remains a favorite for applications requiring high suction lift or the ability to handle slightly more viscous fluids.

Unlike plunger pumps where the seals are stationary, the piston design features “cups” that move with the piston rod inside a stainless steel sleeve.

Essential Service Kits

Because this is a piston pump, its internal wear parts differ from the standard 310 plunger series.
