Directional control valves
D&D Ricambi Srl: the leader on supply of hydraulic components and systems
hydraulic components for construction, earthmoving, agricultural and industrial machinery

  External gear pumps, series AP

The essential components of series AP external gear pumps are an aluminium alloy body and two gearwheels supported by plain bearings.

The front flange can be the SAE standard, or the British or German OEM patterns.

The various frame sizes can be combined with each other, enabling double and triple pumps to be assembled.


High overall efficiency thanks to optimised hydraulic compensation
Design and materials that guarantee excellent technical specifications and long life service
Optimum quality/price ratio
Customised models can be built for specific applications
Various components and accessories are available for radial/axial loads, pressure/flow power, etc.


  High Pressure Internal Gear Pumps QX

The QX pumps are the 5th generation of Bucher internal gear pumps, which have proven themselves in thirty years of service around the world. The straightforward and rugged construction guarantees long service life without the need for extensive maintenance. Tandem and multiple pumps are available worldwide in more than 1000 variants.


High pressures
Low noise level
Long service life
Negligible flow and pressure
Insensitive to contamination

  Internal Gear Pumps QXV
(for low-viscosity fluids)

The QVX is an internal gear pump for low viscosity. It can develope pressures of 300 bar with high efficiency at viscosities of around 1 mm²/s. The QXV is beeing used with great success to pump aviation jet fuels, paraffin oil/kerosene, brake fluids, Pentosin and HFA fluids.


Very low noise levels
300 bar can be developed
Outstanding efficiencies
Long service life
Low pump wear
Low sceptibility to cavitation
Good emergency running

  Internal Gear Pump QXP
Metering pump for polyurethane production

The QXP is an internal gear pump for metering isocyanates, polyols, additives and other fluids. Combined with a variable-speed drive, the QXP is being applied very successfully as a metering pump in the production of polyurethane.


precision metering with very low pulsations, even at high pressures.

can be used with high and low viscosities, and with variable-speed drives.

  Internal Gear Unit QXM

The QXM drive unit can be used in open- and closed-loop hydrostatic drives, and can operate both as a pump and as a motor.

The QXM works as a pump to lift the load and it can recover energy when the load is being lowered.

Used as a bi-directional pump / motor (four-quadrant operation), the unit can power the complete motion cycle of a cylinder.


Very low noise levels
Negligible pressure pulsations
Long service life
Suitable for special fluids
4-quadrant (fully bi-directional pump / motor) or
2-quadrant operation is possible
Low susceptibility to cavitation
