Hydrotrole Ltd. have been supplying hydraulic/hydropneumatic accumulators, pressure vessels and associated equipment for over 35 years. We offer all types: piston, bladder, piston-cum-diaphragm, piston-cum-indicating rod, piston-cum-magnetic switching, float and bellows; sizes from 0.1 to 5000 Litres; and pressures up to 300 Bar (43,000 psi). We have plants in North Carolina in the USA and Stockport in the UK, employing about 15 people on each site. Products are manufactured under a quality system, previously: ISO 9001:1994 [DNV Nbr. 95-LON-QA-458 (15105)]. And jointly: ASME "U" Cert 29,289 5 Nov '96 through 5 Nov '99, and through 5 Nov '02 [Kemper/BVQI - QSC 97028/50591 1997/98]. Now via LDi UK - RSA to ISO 9001:2000 valid through 6 October 2007. When you require products assembled under the auspices of that third party they will come via that UK source. We supply hardware (178,123 different products licensed from M.R. Packer) and software for pulse and shock analysis. In addition, we can provide analysis based on oscillographic data capture, finite element analysis using ANSYS, and pipe vibration frequency analysis using Caesar II. Mission Statement Hydrotrole Ltd. will be the world leaders in Hydropneumatic Accumulators and Pressure Vessels by focussing on quality, customer satisfaction and innovation at all levels throughout the company.

HydroTrole: Hydraulic and Control Engineering since 1963. Piston Accumulators | Bladder Accumulators | Accumulator Safety Blocks | Contact Hydrotrole The name hydropneumatic accumulator covers those hydraulic products that are designed specifically for the storage (accumulation) of liquid under pressure. However, because of the improvements in design of equipment, which has grown from the storage devices, other functions have become loosely associated with the name Accumulator. These other types of units should more properly be called by their function, e.g. – Pulsation Dampers, Liquid Borne Noise Silencers, Line Shock Alleviators, Pump Controllers, Transfer Barriers, etc. More about accumulators... ![]() |
