Aluminium body hydraulic gear pumps

Gear pumps built in three pieces with an extruded body in high resistance aluminium alloy.

WHISPER is a new and original technology protected by international patents and applied to a family of external gear pumps that feature low noise emissions. The wide choice of shafts, flanges and ports, in compliance with all international standards (SAE, DIN and EUROPEAN) allow for their use in an infinite variety of applications.
