DP56 Diesel Power Pack
Our DP56 diesel power unit was primarily designed for the offshore industry, like all our plant, we have had this built into a crash frame with forklift sleeves and LOLAR certified lifting points for ease of moving around site, mobilisation and de-mobilisation.
This powerpack is powered by a Lombardini water cooled diesel engine.
As would be expected of a pack designed for offshore work it is built to last in the harshest of environments and meets all current regulations. Our diesel hydraulic power pack with its 56 lpm flow means it has the ability to run our whole range of Stanley underwater tools range of diver tools. From the GR29 Grinder to the HD25 underwater hammer drill, both concrete and wood cutting chainsaws, core drill rigs, breakers and right down to our small peanut grinder.

There are also a number of other applications for this power pack from powering winches and rams though to harbour cranes and utility services equipment. The flow and working pressure of the DP56 also means it can cope with various long hose lengths, we can supply short lengths of 10 meters hoses to a 100m hose on a hydraulic reel.
Stanley GT18 hydraulic power pack HPU is in our opinion the Rolls Royce of petrol Power Packs. It is capable of delivering either 20 or 30lpm at 145bar. These units are powered by a Briggs and Stratton 18hp Vanguard V twin engine which has proved to be both powerful and reliable and is probably the most widely used unit amongst inshore diving contractors, we are fortunate enough to have three great well maintained units available.
