New air-over-hydraulic pumps: the
XA-Series Xvari
The new XA-Series Xvari Technology air-over-hydraulic pump developed by Enerpac offers tremendously high oil delivery, precise control and ergonomic operation: Shaw Hydraulics is the UK distributor
Never before have these three vital product characteristics been combined in one hydraulic pump With Xvari Technology, Enerpac has again set a new industrial standard for succeeding the 50-year old technology of current air-over-hydraulic foot pumps

Shaw Hydraulics announce the new ZE Series 700 bar hydraulic pump for industrial applications.
Synchronous lifting system is accurate
Synchronous lifting system uses hydraulic cylinders for high accuracy lifting and positioning of heavy loads and objects of any size and tonnage can be lifted and manoeuvred.
The Xvari Technology replaces the popular and widely-used linear air motor technology with improved ergonomics, precise metering of the hydraulic oil flow and also offers a higher oil delivery for increased productivity and efficiency.
The 700 bar pumps enable users to continuously and precisely control the amount of hydraulic oil flow in advance and retract mode and thereby the speed of the hydraulic cylinder or tool that the pump is powering - specifically for jobs that require accurate load positioning, aligning and controlled descend.
Enerpac is "breaking the mould" by applying a two pedal design; one for tool advance (pressure) and one for tool retract (release).
This two pedal design meets the objectives of an ergonomically better product.
the pedals are depressed with the ball of the foot, whereby the heel stays on the ground.
The bodyweight therefore rests on two legs during the operation.
This causes less fatigue and provides increased stability and better control over the degree of pressing and thus the control of the pump.
To control the pressure, the pump can be optionally equipped with an integrated pressure gauge.
The completely closed housing is manufactured from durable glass-filled nylon and provided with extra protection on the corners in the form of stiff cast rubber corner pieces.
The advantage of the Xvari technology is that the user has more control over the hydraulic pump and work being performed.
Higher piston speeds result in a smooth oil flow compared to the pulsating oil flow of the conventional air-over-hydraulic technology.
A closed oil reservoir prevents leakage and eliminates internal contamination from airborne particles.
Stability of the XA-Series pump is second to none with a slightly larger base area.
With the higher oil flow, the time required to run out the cylinder or tool and build to maximum pressure has been considerably reduced.
Compared to many conventional air-over-hydraulic pumps the XA-Series is up to two times as fast.
