CAT 3CP1140 High Pressure Pump – 13.6 LPM 150 Bar

The CAT 3CP1140 High Pressure Pump is a premium-quality triplex plunger pump engineered for demanding commercial and industrial pressure washing applications. Manufactured in Japan by CAT Pumps, the 3CP series is renowned for exceptional reliability, long service life and smooth, efficient performance.

Designed for vehicle washing, industrial site cleaning, pressure washer systems and test rigs, the CAT 3CP1140 delivers 13.6 litres per minute at up to 150 Bar (2,175 PSI). Its precision-engineered triplex plunger design reduces pressure pulsation while maximising efficiency, making it an excellent choice for continuous-duty operation.

A key advantage of the CAT 3CP range is its internally cooled seal system, where pump seals are continually lubricated and cooled during operation. This significantly extends seal life and reduces maintenance costs compared to many conventional pumps.

Compact in size yet exceptionally durable, the CAT 3CP1140 is ideal for installations where space is limited without compromising on performance.
