High Pressure Pumps

HYDROWATT pumps are generally designed for pressures up to a max. of 415 bar (6'000 PSI). On request special executions with up to 600 bar (8'700 psi) are possible. The wide range of pump sizes, with 5, 7, 10 or 14 pistons (cylinder), means that an equally broad flow range is available, from approx. 20 – 800 litre/min (5 – 200 US-gpm).

The hermetic sealing of the displacement (pressure medium) to the pressure-lubricated drive of the pump allows high piston speeds and thus also the construction of high-speed pumps. All of our pumps are therefore flanged directly to commercially available electric motors without intermediate gears.

The standard speed ranges are: 1'500 rpm (at 50 Hz) or 1'800 rpm (at 60 Hz). All pumps can also be operated at variable speed (VFD).

All HYDROWATT pumps are designed for heavy industrial use in continuous 24/7 operation.
