This is jbj Techniques Limited

External gear pumps, the most popular pumps used in modern hydraulic systems. The combination of FEM (finite element method) simulation and latest production techniques has seen one range of hydraulic systems satisfy demands for efficiency, reliability and reduced noise. With displacements from 0.086 to 200.3 cc/rev and maximum continuous working pressures of up to 280 bar this range of gear pumps satisfies demands of a wide range of applications. www.jbj.co.uk/gearpumps.html Versatility, power, compactness & 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. www.jbj.co.uk/vanepumps.html Volumetric self-priming screw pumps suited to handle oils and liquids with a minimum lubricating quality. The design simplicity makes these screw pumps intrinsically reliable and efficient. Three epicycloidal screws rotate inside a replaceable casing with close tolerances, so forming sealed chambers and provoking the axial displacement of the fluid. The idler spindles rotate without contact with the driving spindle because of the fluid itself, therefore being free from radial forces. The accurate hydraulic balance and the special profile of the screw thread guarantee a continuous flow with minimum pulsations and turbulance, resulting in extremely low noise levels even at high rotational speed. www.jbj.co.uk/screwpumps.html www.jbj.co.uk/pumpsandmotors.html jbj Techniques deal with customer needs; products for new systems, design and support, and most importantly limiting existing machinery downtime.
