Versatility, power, compactness and low running costs are the main characteristics of
B&C vane pumps.
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 down time.
The cartridge contains a rotor, vanes and inserts, a cam ring, two flexible plates and
During operation the rotor is driven by a splined shaft coupled to the drive unit.
As the rotation speed increases, centrifugal forces, in combination with the pressure
generated behind the vanes, push the vanes outwards,
where they follow the profile of the cam with a sufficient contact pressure to ensure
adequate hydraulic sealing.
The two opposed pumping chambers formed by the elliptical profile of the cam
cancel out radial loads on the shaft bearings, thereby giving them extremely long
The BQ series is available in five versions of single pump (from 8 to 230 L/min at 1200 rpm) and seven versions of double pump (from 55 to 370 L/min at 1200 rpm), with maximum powers of over 300 HP. The BQ series pumps are extremely compact and are supplied with ISO norm mechanical couplings and SAE norm hydraulic fittings. This makes them very easy to install and guarantees their interchangeability with other similar pumps.
