HQ series of hydraulic vane pumps - Vane pump HQ02G14

Fixed displacement hydraulic vane pump HQ02G14 (clockwise - right direction of rotation) - hydraulically balanced, with capacity determined by the type of ring used and the rotation speed. Features: displacement 45,4 cm³, rotation speed up to 2700 rpm, operating pressure up to 210 bar. It can be used for mobile applications mainly. This version is equipped with NBR seals. Direct and coaxial drive by means of a flexible coupling is recommended.

Technology:
The design of the HQ series vane pumps makes them particularly suitable for application on trucks, especially garbage 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. In addition to reliability, HQ pump guarantees continuous high volumetric efficiency during its whole servicetime. That avoids having to compensate the typical efficiency loss of other kinds of pump, increasing the truck engine RPM, which causes higher fuel consumption and therefore air pollution.
The HQ series is available in 2 versions of single pump (from 39 to 88 l/min at 1000 rpm) and two versions of double pump (from 46 to 134 l/min 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 possibility to orientate the inlet and outlet ports, makes the HQ pumps very easy to install and guarantees their interchangeability with other types of pumps.

Advantages:

Versatility;
Small dimensions;
High long-term volumetric efficiency;
Low noise level.

Working conditions:
A pump is the heart of hydraulic system. We would like to remind you that the pump's longevity and its technical performance during operation depend directly on the working environment. This environment is essentially made up of: the PTO - its speed, and torque, the tank - capacity, position etc., the fluid - its type, viscosity and cleanness, and the way of the pump is used - type of application, dyty cycle etc. Contact us for advice on defining the right environment for the pump.
