ATTENTION !
Check the ports of your HPW-pump and connect it to hydraulic and pumping fluid circuits according to
their markings !
1. If the hydraulic pressure line will be connected by accident to the return port and return line
correspondingly to the pressure port, it will not cause any harm to HPW-pump, however pump will not
operate.
2. Output power of HPW-pump depends on the pressure difference between pressure and return lines.
The more is the pressure in return line, the less is concerned pressure difference and output power of the
pump. The fact should be taken into account when certain number of machines are intended to be joined-up
in series.
3. Since the piston assembly reverses extremely rapidly (refer to the TECHNICAL SPECIFICATIONS), certain
oscillation can be imposed to the return line because of pressure pulsation. In order to reduce both pressure
pulsation and return line oscillation, the flexible hose with textile fabric cord is recommended to be used in
return line to protect from damage low pressure units, such as oil cooler.
4. Prior to connecting HPW-pump to hydraulic circuit, compatibility of used equipment should be ensured.
Hydraulic pressure and flow rate produced by hydraulic circuit should meet values demanded by your
HPW-pump. Refer to the technical specifications.
