Keep Your Hydraulic Systems Running Smoothly with Rotec’s Accumulator Charging and Servicing

Hydraulic accumulators are crucial components in a wide range of equipment, from excavators and cranes to wind turbines and drill rigs. These devices store energy in the form of pressurized fluid, helping to optimise system performance by mitigating pressure fluctuations, absorbing shocks, preventing contamination, and providing supplemental energy. They achieve this using a bladder or diaphragm to separate inert gas (typically nitrogen) from the hydraulic fluid.

While generally low-maintenance, accumulators can experience performance degradation over time. Common issues include tears in the bladder or diaphragm, loss of pre-charge gas, and seal deterioration. Overpressurisation and fluid contamination are the most common cause, as is improper installation.

Accumulator Safety and Compliance

Safety is paramount when dealing with pressurised systems. Under the Pressure Systems Safety Regulations 2000 (PSSR), the user/owner is legally responsible for ensuring a written scheme of examination is in place before accumulators are put into operation.

These regulations mandate periodic inspections by a competent person to ensure the safe operation of hydraulic systems and protect personnel from potential injury. Compliance with PSSR is essential for all accumulator users.

Four HPUs Commissioned for Canal Lock Gates

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.

Rotec Holdings announce the acquisition of Ram Reman

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.

Rotec success has led them to be key suppliers to number of well-known organisations such as the Ministry of Defence, Babcock, Airbus and Western Power Distribution. The acquisition of Ram Reman now enables the group to add the design and manufacture of hydraulic cylinders to its product portfolio, strengthening its expertise and adding to the supply of all component and systems requirements to its considerable customer base. Ram Reman will continue to trade as an autonomous trading entity, but will of course strengthen the Group’s capabilities as a whole. Rotec are happy to have the continuity of management skills of John and Niki Beavon, and Thelma Morris, with whose help it is proposed to drive the business forward. The aim of the newly acquired business is to increase the overall Groups manufacturing capability, including fabrication, and design and build solutions to customer requirements.
