jbj Techniques Limited Fixed Displacement Hydraulic Vane Pump HQ Series

Description
Versatility, power, compactness and low running costs are the main characteristics of vane pumps from jbj Techniques. 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 and two covers. 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 of the ring 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 versatility of the BV series pumps enables them to meet the requirements of the most varied industrial applications. In fact, as well as their proven high reliability and excellent volumetric efficiency in all working conditions, they operate with particularly low noise levels. This is made possible by the special profile of the cam ring and the use of a 12 vane rotor that reduces the amplitude of the supply pressure pulses, thereby reducing induced vibrations. From small individual components to large combinations. Engineered product packages for a wide range of applications. » product specification team of design engineers to assist in design process simple or complex, standard or bespoke. » prompt product supply large stocks for next day delivery on many items. » machine shop full machining services for bespoke designs.
