Product Description

7 Frame Plunger Pump

CAT Pump model 530 is a triplex plunger pump that operates with low pulsation and high efficiency. Constructed with a chrome-plated brass manifold that is extremely resistant to corrosion. Valve assemblies are made of 304 stainless steel. Solid ceramic polished plungers provide a true wear surface for extended seal life. Seals and O-rings are made of NBR (Buna-N). The CAT 530 pump is engineered to lubricate and cool the seals as the liquid moves through it during operation. Shaft protector is sold separately.
