High-Pressure Pump Repair

Watermaker High-Pressure Pump Repair — San Diego

The high-pressure pump is the heart of your watermaker. Cat Pumps, Danfoss APP axial-piston pumps, and Spectra's Clark Pump all wear over time. Symptoms include pressure loss, oil misting, unusual noise, and inability to hold 800 psi.

Pump platforms we service

Cat Pump plunger pumps, Danfoss APP 0.6 / 0.8 / 1.0 / 1.5 / 2.5 axial-piston pumps, Spectra Clark Pump energy-recovery units, and legacy triplex pumps on older frame systems.
