White Hydraulics has developed a new release pump for mobile equipment.

'The release pump was designed for the mobile equipment market and to compliment our hydraulic motors and brakes', says Jeff Englehardt, Director of Marketing. 'However, it can be used with any spring applied/hydraulically released braking mechanism'. 'The release pump is an inexpensive, one-piece alternative to buying and assembling the traditional components - screw-in cartridge hand pump, directional control valve and manifold block - used for brake release'.

'It is ideal for both new installations and retrofits'.

The release pump combines simplicity and safety into one easy use package.

The high-strength aluminium body has two 0.375in-16 UNC threaded through holes for easy mounting, and is rated for pressures up to 4000lb/in2.

The release pump is available with 4 SAE ports or -4 JIC fittings installed.

The valve rod and pump rod are size- and colour-coded for quick and easy identification in inclement conditions.

The release pump is designed to deliver an output pressure of approximately 500lb/in2 with normal hand pressure.

It typically takes up to five pumps to generate enough flow to release a typical White Hydraulics brake.

The release pump's built-in safety feature ensures the equipment's normal braking operation is never accidentally disabled.

If the hydraulic circuit is pressurised at any time while the brakes are being released or after they have been released, the valve rod will automatically pop out and the mobile equipment will revert to its normal operation.

Applications for the release pump include scissor lifts, boom lifts and fork lifts among others.
