Wilden HS430S FIT Metal High Pressure Pumps

1-1/2” | 38 mm

Wilden HS430S FIT Metal High Pressure Pump performance. A reliable performer, this pump has superior flow rates and can produce higher pressures (250 psig vs 200 psig) compared to competitor 1-1/2” (38 mm) pumps.

The FIT design uses a wetted path that minimizes the number of fasteners and allows for single socket reassembly for faster, easier maintenance compared to legacy Wilden pumps and competitor high pressure pumps.

Wilden HS430S FIT Metal High Pressure Pumps are designed for superior containment, are direct replacements for existing 1-1/2” (38 mm) high pressure pumps and do not require repiping of your application. The HS430S FIT high pressure metal pumps feature a “Simplex” design – meaning that one liquid chamber is used to pump fluid while the other is used as a pressure amplification chamber. With a 2:1 pressure ratio, this pump generates 17.2 bar (250 psig) and does not require costly external boosters or amplifiers to achieve this discharge pressure.
