New hydraulic power unit improves all round

Berendsen's Lynx hydraulic power unit is versatile and well designed at a highly competitive price that also minimises installation and running costs.

Small standard hydraulic power units have been produced by numerous companies including Berendsen for many years; but in designing their new "Lynx" units from scratch and challenging previous design norms Berendsen have produced a unit that is of high quality, is versatile and well designed at a highly competitive price that also minimises installation and running costs.

Berendsen's investment in the design of these units has produced a product that will ensure high reliability and low maintenance throughout its life.

The design of tank is stronger and quieter than conventional reservoirs.

By selecting the best components from leading international suppliers Berendsen are confident that the units quality need never let their customers product or plant down.

Throughout the design phase cost was always a consideration, commonality of components across the range together with a modular construction ensures that Berendsen can produce a cost effective unit in the shortest possible lead time.

Components are continuously held in stock providing flexibility on any build configuration and the ready availability of spares.

Furthermore, supplying the unit with valves mounted and tested, the unit painted, mountings designed-in, lifting eyes provided and optionally the motor wired to a starter isolator, all goes to providing their customers with an hydraulic power source that will dramatically reduce their installation time and costs.

Initial purchase price and installation costs are only part of the cost of any machine and Berendsen have designed their new units to reduce running and service costs to a minimum.

The number of standard options of flow and power along with the high-pressure capability of these units makes it possible to accurately match power requirements, providing efficiency savings over a machines life.

Noise levels have been reduced (to 75 dBa)- improving the environment in which the units are used, this has been achieved by making the tank stiffer, submerging the pump and the careful selection of components.

Reduced noise improves the productivity of those using the machine it powers.

Service costs are reduced by prolonging system life with a 10m nominal return line filter and a filter breather fitted as standard.

The unique tank lid design and gasket mounted components also eliminate the ingress of contamination.

Routine maintenance is simplified with oil level/temperature, element condition and system pressure gauges being clearly visible; breather, filter and solenoid replacement and system pressure adjustment can be achieved with ease.

Berendsen's new power units also offer environmental benefits, not only has the noise level been reduced but the design of these units has eliminated leakage (hence no drip tray) and the use of stacking valves reduces the number of connections therefore potential leak paths on the machine that they are powering.

Lynx hydraulic power units are initially available with nominal tank capacities of 30 and 60 litres, flow rates from 1.8 to 22 L/min, operating pressure from 7 to 210 bar (Higher on request) and electric motors from 0.55 to 4 kW.

In addition to the basic power unit customers can specify up to six valve stacks (each stack can contain pressure, flow and directional functions) which are assembled onto the power unit and tested prior to delivery, making for a remarkably compact and efficient system.

In the majority of cases there is no need for additional hydraulic valves within a circuit.

Berendsen also design, build, install and commission power units and systems of virtually any size and complexity.
