B & C Hydraulics HQ Series Vane Pumps

The design of the B & C Hydraulics HQ series pumps makes them particularly suitable for application on trucks, especially rubbish compactors.

All the components subject to wear are contained in a cartridge unit that can be easily removed for inspection and/or replacement without disconnecting the pump from the circuit, drastically reducing expensive machine downtime. The special design of the inner flexible plates of the cartridge enables any thermal expansion in the rotor to be compensated for and to adequately cope with any sudden change in pressure.

Furthermore, the two opposed pumping chambers formed by the elliptical profile of the cam cancel out radial loads, dramatically reducing vibrations and considerably increasing the pump lifetime.

In addition to reliability, the HQ pump guarantees continuous high volumetric efficiency during its service time, avoiding having to compensate the typical efficiency loss of other kinds of pump, increasing the truck engine RPM, which causing higher fuel consumption and therefore air pollution.
These characteristics, along with an extremely low noise-level, make the HQ pump environmentally friendly.

The B & C Hydraulics HQ series pumps are available in:

• three versions of single pump:  HQ02 | HQ03 | HQ22 from 39 to 88 litres/minute at 1000 rpm, and
• four versions of double pump: HQ21 | HQ22 | HQ31 | HQ33  from 46 to 134 litres/minute at 1000 rpm with maximum powers of over 103 kW.

The pumps are extremely compact and are supplied with different types of either ISO or UNI norm mounting for the direct coupling with PTO and SAE norm hydraulic fittings. That, together with the option to orientate the inlet and outlet ports, makes the HQ pumps very easy to install and guarantees their interchangeability with other types of pumps.
