Bell Hydromatics | Piston Pumps

HV Series Variable Volume Piston Pumps

Combining special internal designs and strict engineering disciplines has reduced noise level to new lows in whole pressure zones.
Depending on variety of application needs multiple optional unique control methods are available, it does not only reduce a number of unnecessary hoses, pipes and control valves but also increase efficiency and save horsepower, and cost.
Less capacity reservoirs can be selected and applied because of performances of low pressure loss and less head generation.
Wide application ranges:it is very suitable for machine tools, plastic injection molding machines, forging machines and other industrial machines etc..
Mounting flanges are made to SAE A or B 2-bolt (V15.18, 38 types) and SAE-C 2 & 4-bolt (HV-50.HV-70 types).
