Rotec are proud to have commissioned four new Hydraulic Power Units (HPUs), located at The Saltersford Large Lock, in Barnton, Cheshire.

Once a busy commercial waterway, the canal is now only used by leisure traffic and the occasional barge or larger ship.

Rotec were asked to design, manufacture, install and commission four HPUs, each one to control a sluice and lock gate cylinder.

HPUs (sometimes referred to as hydraulic power packs) are a self-contained system that incorporate a motor, a fluid reservoir, and a pump. Through pressure and enclosed fluid, energy is transferred to subsequently create rotary motion, linear motion, or force. Hydraulic systems enable smaller forces to be multiplied into bigger forces.

The four HPUs on this project each comprised a 200-litre oil reservoir manufactured in 316 stainless steel, electric motor, bell housing, coupling assembly, hydraulic pump, pressure filter and control valve assembly.

Designed to operate at a flow of 23 litre/min at a pressure of 160 Bar, the pressure can be increased to a maximum of 250 Bar.

Dale Lockart, Stroud Service Centre Manager, commented,

It was a pleasure to support this project from the design phase, right through to the commissioning of the four Hydraulic Power Packs. We look
forward to working on similar projects and with our clients again in the future.

From an old butchers shop to one of the Uks leading Hydraulic Distributors and manufacturers! Rotec Holdings Taunton based Head Office, are pleased to announce the acquisition of Ram Reman Ltd, the cylinder manufacturer and repairer of West Moors, Dorset. Rotec commenced trading in Taunton in 1979 retailing hydraulic hose and fittings and industrial hose from an old butchers shop in the Halcon Estate area. After a couple of years trading, the Directors recognised the need for a technical design and build facility, which resulted in the employment of experienced hydraulic engineering staff. The Company then proceeded to supply hydraulic power packs and electronic control systems to a variety of industries including items for use in tunnelling equipment, forestry forwarders and naval equipment. In 2003 the Company the company was recognised by Parker Hannifin Plc and appointed a Hydraulic Technology Centre for the South West distributing their range of hydraulic equipment. Parker Hannifin, one of the world’s largest manufacturers of hydraulic equipment is recognised throughout the world for their quality and range of hydraulic equipment. This opportunity, coupled with a management buyout in 2007, allowed the expansion and opening of two further depots in Plymouth, and Stroud. The Company employs a total of thirty two people, twenty one of whom are at their Priorswood HQ, and the principal manufacturing facility.
