JBJ Techniques has introduced a range of hydraulic vane pumps that can be used in most industrial applications.

The vane pumps have been designed to offer versatility and power in a compact size and with low running costs.

All components that are subject to wear are contained in a cartridge unit that can be removed for inspection and/or replacement without disconnecting the pump from the circuit.

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.

With their high reliability and volumetric efficiency in all working conditions, the pumps 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.

All pumps are hydraulically balanced, with capacity determined by the type of cartridge used and the speed of rotation.

The BV Series of fixed displacement hydraulic vane pumps is available in six versions with capacities from eight to 55 litres/min (from 2-14gpm) at 1,200rpm and seven bar.

The BQ Series of fixed displacement hydraulic vane pumps is also available in seven versions with capacities from eight to 55 litres/min (from 2-14gpm) at 1,200rpm and seven bar.

The TQ/TV Series of through-drive hydraulic vane pumps is available in five different displacements from 47 to 79 litres/min (from 12-21gpm) at 1,200rpm and seven bar.

The HQ Series of fixed displacement vane pumps is available in five different displacements from 39 to 66 litres/min (from 10-17gpm) at 1,000rpm and seven bar.

The B1/B2 Series of fixed displacement vane pumps is available in eight different displacements, from 3.29cc to 22.8cc.

JBJ Techniques

JBJ Techniques is a specialist supplier of high-quality products for the mechanical power transmission and fluid power sectors. The company offers a high level of in-house expertise plus a huge selection of products to meet a very broad range of customer applications.

JBJ Techniques is a specialist supplier of high-quality products for the mechanical power transmission and fluid power sectors. The company offers a high level of in-house expertise plus a huge selection of products to meet a very broad range of customer applications.

From specification, through technical advice and manufacture to after-sales support, JBJ Techniques provides a comprehensive and valued service to the power transmission and hydraulics industries. The company fields a UK-wide team of technical sales engineers to ensure that the business is close to its customers, and it enjoys excellent associations with European manufacturers, acting as sole UK distributor in many case.

JBJ’s team is recognised for its expertise in the selection and configuration of hydraulic and mechanical transmission systems. Able to draw on an extensive product range that provides the building blocks for bespoke systems both large and small, the in-house design team offers a complete service, ranging from an assessment of customer requirements to full technical backup, including engineering calculations, CAD-based system design, system build and certification. Moreover, customers can take advantage of JBJ’s own machine-shop facilities and skilled craftsmen to guarantee quality and control cost.

JBJ Techniques provides probably the widest range of couplings available within the UK with 14 different designs and 22 different styles of gear couplings alone. The product portfolio includes miniature couplings, all-steel gear couplings, flexible spider couplings, shaft couplings, torque limiting couplings, disc and grid type couplings, ATEX compliant and shaft locking devices.

However, as extensive as the selection is, couplings make up a fraction of JBJ’s portfolio. In addition, the company can provide gearboxes, clutches, pumps, hydraulic motors, flow meters, fluid power accessories — including cooling systems, reservoirs, seals and indicators — as well as a variety of bellhousings and flanges, to name just a few of the product categories.
