Frequently Asked Questions

Q: What motors are compatible with the 1812/1814 High Pressure Triplex Plunger Pump?

A: This triplex plunger pump is designed to work with motors rated between 2.2 kW and 4 kW. It supports multiple shaft configurations — 24mm inner shaft, 28mm inner shaft, and 24mm outer shaft — making it compatible with a wide range of motor coupling setups commonly used in car wash and industrial cleaning systems.

Q: What is the difference between the standard and automatic versions of the 1812 pump?

A: The automatic version includes a built-in automatic unloader valve. This means when the trigger gun is released (no flow demand), the pump automatically bypasses pressure, reducing wear and extending pump life. The standard version requires a manually operated unloader or external bypass valve.

Q: Is this pump suitable for continuous commercial car wash use?

A: Yes. The 1812/1814 triplex plunger pump is built from stainless steel and features a three-cylinder plunger design that minimizes pulsation and handles continuous high-pressure operation reliably — making it an excellent choice for commercial car wash stations and industrial cleaning rigs.

Q: What is the maximum pressure output of this pump?

A: The pump delivers up to 200 kg/cm² (approximately 2,845 PSI) of working pressure with a flow rate of 16 L/min, providing strong and consistent water delivery for vehicle washing and industrial surface cleaning tasks.
