Versatility, power, compactness and low running costs are the main characteristics
of BD 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 pins, a cam ring and two supports.
During operation the rotor is driven by a spline 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 lifetimes.
The BD series is available in three versions of single pump (from 10 to 227 l/min at 1000 rpm) and four versions of double pump (from 20 to 385 l/min total, at 1000 rpm), with input powers of over 328 KW at max pressure and speed.
The BD series pumps are extremely compact and are supplied with SAE norm hydraulic flanges and shafts.
This makes them very easy to install and guarantees their interchangeability with other similar pumps.
