The EPW275-10AR/DE is an electric start, 10 hp diesel driven pressure washer with a maximum output of 275bar or 4000psi. It comes with an Italian-made Annovi Reverberi Triplex professional triplex pump, and this washer is built to be put to work on commercial cleaning jobs and is of an industrial quality.
The pump comes with a brass head and ceramic pistons which helps with crack resistance and is generally much more hard wearing than the aliminium pumps found on a large proportion of pressure washers. Coupled with the brass head pump, theceramic pistons can also help stop rusting or wear, especially when using detergent. It is powered by the Hyundai D400, which is a 10hp, 420cc, direct injection diesel engine, which is more economical to run and can also prolong the lifespan of the machine. Being a Hyundai engine, this ensures the driving force of this pressure washer is reliable and long lasting. The engine itself has electric key start with a heavy duty 36ah sealed battery, making it a pleasure to start and work with continuously.
Like all other pressure washers in the Evopower range, it has a thermal relief valve for pump protection against heat. t's a failsafe mechanism for machines that have been left running without the trigger on the lance being fired. The valve dispenses the water that circulates around the pump and gets hot, and replaces it with cooler water. This is because process can be damaging to the pump innerds so the thermal valve helps to make sure this doesn't happen. It comes with a rugged 4 wheel tubular frame with lifting hook. It has bronze conrods for longer life and can draw from a barrel if gravity feeding.
It has a 15m high pressure hose, 3m suction hose, fitted suction filter, turbo nozzle and 5 standard quick release nozzles included in the package. It can also be fitted with an optional hose reel.
It also has a detergent foam injection and a parking brake for safety.
Diesel pressure washers are also known for their fuel economy, with typical running costs around 1 to 1.5 litres an hour at 70 pence a litre for red diesel. (Compared to a petrol pressure washer running at 2 litres an hour at £1.40 per litre) meaning that you can get upto a 75% saving in fuel costs.
The rugged tubular steel frame with heavy duty wheels and tyres, as well as lifting hook is designed to last and protect the engine and pump and it comes fully tested and inspected, filled with oil ready for us, and all you need to do is just add diesel and it's ready to use.
Below is a list of key terms for this pressure washer, explained in a little more detail:
Brass Pump Cylinder Head
High pressure pumps can have cylinder heads made from either aluminium or brass. The forged brass pump head is by far the best option, giving a longer lifespan and greater resistance against cracks due to frost damage. N.B. whatever type of pressure washer you have, it is advisable to prevent frost damage by not storing in areas that will have a temperature drop below zero Celsius.
Thermal Relief Valve
This is to protect the pump from over heating. The pump will not over heat when in normal use, however, with all petrol and diesel engine driven pressure washers, when the trigger on the lance is released and you are not pressure jetting, the engine continues to run, but there is no flow of cool water through the pump. This flow of water keeps the pump cool and also lubricates the seals. When you are not jetting, the pump continues to pump, but the flow of water through the trigger gun is stopped, so the water in the pump body is re-circulated around the pump, this water gains heat after a few minutes. The thermal relief valve will release valve the hot water when it reaches 60 degrees Celsius, this is replaced with cool water and prevents damage to the pump and seals. It is good practice and saves fuel to always switch the engine off when you stop jetting for more than a few minutes.
Each triplex pump has three ceramic pistons. Ceramic pistons offer a far greater lifespan than stainless steel or aluminium pistons. They also increase the life of the seals, as they have a smoother surface.
The pressure is adjustable from zero to the maximum of 3600psi. The adjuster features forged brass housing and stainless steel banjo bolts, attaching the external unloader valve to the brass head.
The outlet of the pump unloader valve has a chemical hose connector. The chemical function is activated when the black low pressure nozzle is used in the end of the lance. This would be used to spray a vehicle with detergent, then the high pressure nozzle would be used to jet the detergent off the vehicle.
Bronze Connecting Rods
The connecting rods are a highly stressed component connecting the ceramic piston and the steel crankshaft. For commercial use machines it is essential that the con-rods are made from bronze. Lower quality pumps often have aluminium connecting rods, which are not designed for long periods of use. Bronze is a lot stronger and has better lubricating properties.
