HAWE HQI Hydraulic Gear Pump

HAWE HQI hydraulic gear pump is an internal gear pump family intended for hydraulic systems that require high efficiency, constant displacement and high-pressure capability. HAWE designs the HQI as an industrial pump for high pressures, with axial and radial compensation used to support efficient operation. The family is covered across HQI2, HQI3 and HQI6 pumps, giving the series a broad selection range for different machine sizes and hydraulic flow requirements. This makes HQI suitable when a designer needs an internal gear pump rather than an external gear pump arrangement.

The HQI design is intended to reduce volume and pressure pulsation, which supports low running noise and smoother hydraulic operation. HAWE also features the length of the gears contributes to low pulsation behavior. These properties are useful in hydraulic systems where acoustic performance, stable pressure delivery and efficient continuous operation matter. HAWE HQI also offers a service life of at least 1 x 10^7 load cycles against peak operating pressure, with the final suitability depending on correct size selection, operating pressure, fluid condition and system design. The pump is therefore well suited for applications where steady pressure delivery and efficient fixed-displacement flow are required over repeated duty cycles.

The displacement range of HQI2, HQI3 and HQI6 extends from 5 to 250 cm3/rev. Thier operating pressure reaches up to 350 bar depending on the selected series and nominal size, so the exact pressure and speed limits must be checked against the specific HQI model. HAWE HQI hydraulic gear pump are used in applications such as industrial hydraulics, mobile hydraulics, process engineering and vehicle construction, covering both stationary hydraulic units and machine-mounted hydraulic systems.
