1. INTRODUCTION
LH high pressure water plunger pumps have been
designed for long life industrial duties and provided they
are correctly installed and maintained will give long
trouble-free operation. Read and understand this
manual before using your pump; it contains the
necessary information for the correct installation, use and
maintenance as well as some practical suggestion for
trouble shooting.
Upon receipt of your pump, inspect for overall good
condition and that no items are missing. Any missing
item or damage should be reported before installing
and starting the pump.
3. SAFETY
3.1 General warnings for safe operation
The misuse of a high pressure water unit and the non-
observance of the pump installation and maintenance
instructions may cause serious damages and/or injuries
to people or properties or both.
Any Manufacturer/Operator requested to assemble/use
a high pressure water unit should be competent to do so,
should have the necessary knowledge on every high
pressure component installed in the unit and on the
precautions to be taken in order to guarantee the largest
safety margins during operation. No precaution, so far
as is reasonably practical, should be left out in the
interest of safety, both from the Manufacturer and the
Operator.
3.2 High pressure unit safety requirements
1. A safety valve should be installed in any delivery line
and should be sized to discharge or by-pass the
entire pump flow rate
2. High pressure unit components, with particular regard
for those units working outside, should be adequately
protected against rain, frost and heat.
3. Electric components and wiring should be provided
with an adequate degree of protection, able to protect
them against spray coming from any direction. They
should also be suitable for working in a wet
environment.
4. High pressure hoses and any other accessory under
pressure should be sized in accordance with the
maximum unit working pressure and must always
work within the safety margins indicated by the nose/
accessory Manufacturer.
5. High pressure hose ends should be fastened to a
steady object in order to prevent them from
dangerous sweeping around, should they burst or
come off their end fittings.
6. Proper safety guards should be provided to
adequately cover transmission joints, pulleys, belts or
auxiliary drives.
