HPW - HIGH PRESSURE WATER PUMPS SAFETY PRECAUTIONS Operating with DYNASET HPW high pressure pump user has to conform to all safety regulations concerning pressurized equipment. Hydraulic circuit has a high pressure 210 bar. EQUIPMENT TECHNICAL CONDITION HAS TO PAY SPECIAL ATTENTION.
HPW - HIGH PRESSURE WATER PUMPS GENERAL NOTES DYNASET HPW-pump is a converter, which transforms actuating fluid power, usually hydraulic oil, into pumping fluid’s power, which is defined by flow rate and pressure. Actuating power is supplied from hydraulic system of carrier machine or other installation. Water or any other pumping fluid can be taken from natural source, reservoir or pressurized supply network.
3-way valve. 2. HYDRAULIC SYSTEM WITH VARIABLE DISPLACEMENT PUMP: .1 In system with OPEN CENTRE the required oil flow is set by DYNASET PRESSURE COMPENSATED PRIORITY VALVE .2 In system with CLOSED CENTRE (load sensing system) the required oil flow is set by DYNASET LS-VALVE kit, which comprises solenoid valve, pressure compensated oil flow limiter and pressure relief valve.

May 2014 HPW - HIGH PRESSURE WATER PUMPS OPERATION Prior to starting-up the HPW-pump it is checked whether all couplings in hydraulic and pumping fluid circuits are properly connected and there are no leakages over the equipment. Ensure that the water tank is refilled and intake line’s strainer/filter is clean. If water (or any other pumping fluid) is taken from pressurized supply, ensure that the shut-off valve is open.
Various high pressure washing and cleaning jobs, such as spray gun washing, pipe and sewer cleaning and street washing, are typical applications of DYNASET HPW-pumps. As special applications, high pressure dust suppression, hydro-demolition and high pressure fire-fighting systems are worth to mention. Compact size and reasonable power demand enable to fit HPW-pump practically to any project, where high pressure water or other fluid is being used.
Equipment kit for opening and cleaning clogged pipelines and sewers is comprised of following units: DYNASET HPW-pump, DYNASET hydraulic hose reel, pressure hose of suitable length and diameter, pipe opening/cleaning multi-jet nozzle head. 1. Unlock the hose reel to enable its free rotating.

May 2014 HPW - HIGH PRESSURE WATER PUMPS ...BASIC APPLICATIONS OF HPW-PUMPS STREET WASHING UNITS 50 - 150 mm 10 - 50 mm When adjusting on-position, the street washing pipe should be brought down horizontally as close as possible to the roadway. An operator should be careful, though most KPL-types are provided with support wheel in order to prevent street washing pipe from damage.
Automatic transmission fluids and even engine oils can be used, if they are allowed to be used in hydraulic system of your carrier machine. Prior to use special hydraulic fluids a with DYNASET equipment, please be kindly requested to contact nearest DYNASET representative for an advice.
