Larger capacity for hydraulic motors
Eaton has introduced larger capacity versions of their hydraulic low speed high torque geroler J series motors. Eaton J-02 motors give a substantial source of rotary power in a very compact envelope.
Complete Self Feed Drilling Systems introduced
Berendsen's new self feed drill units, supplied by Compair Tools and Equipment, combine an air or electric motor with a double acting pneumatic cylinder and associated control valves in one unit.
Both industrial and mobile variants of these new open loop pumps are available in the UK through Berendsen PMC Limited.
Improvements in service life and reduction of in-service costs have been achieved with the adoption of high load bearings, stiff shaft, and a stiff saddle type yoke design which reduces deflection of components within the pumps and therefore reduces the load applied to the bearing surfaces.
Both air and fluid borne noise levels have been reduced, these new pumps feature a unique three piece body design, flange, housing and valve block, which was specifically created to reduce noise levels.
Another feature is the bimetallic timing plate that improves pump filling and so reduces noise generation.
Pressure ripple is astonishingly low at 4%; again this reduces noise but also reduces the stress in the systems pipework improving the integrity of the system as a whole.
The new design PVH pumps are variable displacement axial piston units.
They are available in six sizes from 18 to 131 cc/rev and an adjustable maximum flow stop is provided as standard enabling the accurate matching of the pump to system requirements.
All sizes are suitable for 280 bar continuous operation (320 bar intermittent & 350 bar peak), The industrial derivative is designed to run at up to 1800 rpm and the mobile versions up to 2000 rpm for the 131 cc model and 2800 for the 18 cc pump.
An extensive array of port, flange, shaft, through drive and control options are offered, making this series of pumps easy to incorporate into existing systems.
Further adding to the family's installation flexibility is their compact size, due to the use of a single control piston, and the abundance of case drain positions that permit the pump to be mounted in various positions.
