Ideally suited for applications that require high head pressures such as viscous and solid-laden slurries, the aluminum pump comes equipped with the “Fit” wetted path that minimizes the number of fasteners and allows for single socket reassembly for faster, easier maintenance. The new pump also provides superior flow rates, is easy to maintain and increases plant profitability, Wilden says.

The HS430S FIT high pressure aluminum pump has been designed for superior containment, is a direct replacement for existing 1-1/2” (38 mm) high pressure aluminum pumps and does not require any repiping for your application. This high pressure pump features a “Simplex” design – which means 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.

FIT high pressure aluminum pumps are fitted with the energy-efficient Pro-Flo Shift Air Distribution System (ADS). This innovative ADS provides up to 60% reduction in air consumption compared to competitive AODD pump technologies, Wilden says.
