CAT PUMPS
Knowledge base
Hands-on knowledge from over 50 years of high-pressure technology: sizing, operation, maintenance and troubleshooting – from our engineers for your application.
Fundamentals
Operation
-
Recognising and preventing cavitation
How cavitation occurs in high-pressure pumps, how to recognise it in operation, and which three factors – temperature, speed and inlet pressure – reliably prevent it.

Water quality and fluids
What water quality high-pressure pumps need, what to consider with demineralised and RO water, hot water and chemicals – and why the suction filter decides service life.

Sizing
-
Installation and system design
Inlet conditions, safety valve, pressure gauge, pulsation dampener and line sizing – how a high-pressure system must be built so the pump lasts.
