A Series

David Brown is specialized in pumps production from group A1 to group A3, divided into 34 displacements: from 0,9 to 120 cc/ rev, and up to 320 bar of max working pressure.

Pumps are available with cast iron flanges and covers version to reduce the loudness level.

Hydrostatic balance takes up axial slack through the pressure supplied to a defined bushing area.

Bearings lubrication is automatic and proportional to the pump operating pressure.

Each pump can be assembled whether with standard flanges (European, German or SAE) or with special ones (ZF, Perkins and Renault), with tapered, cylindrical or splined shafts.

Q.jpg

Q Series

In response to market needs, the QR and QS ranges have been developed to combine very high efficiencies with very low noise levels while retaining the rugged simplicity of well-proven hydraulic gear pumps.

Both series are of cast iron construction and high quality steel gears are supported by hydro dynamic plain (bush) bearings which are lubricated by a system which draws cool fluid from the inlet port.
QR spur gear pumps are designed for minimum pressure ripple while the QS Series features patented helical gears which reduce ripple and noise levels even further.

The pumps will work to peak pressures up to 280 bar (4060 psi) and careful attention to inlet porting enables most pumps to run at up to 3000 rev/min.
