INSTALLATION INSTRUCTIONS - P532 and P536
Check oil level prior to starting and ensure troublefree water supply.
Pressure in the discharge line and pump must be
at zero before any maintenance to the pump takes
place. Shut off suction line.
Important!
If there is a danger of frost, the
water in the pump and in the pump fittings (particularly the unloader valve) must be emptied. The
second discharge port can also be used and the
pump run “dry” for 1-2 minutes for this purpose.
Disconnect fuses to ensure that the driving motor
does not get switched on accidently.
Make sure that all parts on the pressure side of
the unit are vented before starting the pump. In
order to prevent air, or an air-water-mixture being
absorbed and to prevent cavitation occurring, the
pump NPSHR (=suction head) and water temperature must be respected.
Oil: Use only 68 ounces (2 litres) of SAE 80-90W
gear oil (p/n 01154).
Initial oil change after 50 operating hours and then
every 1000 hours, after 1 year if used less.
Caution: When operating in damp places or
with high temperature fluctuations, oil must be
changed immediately (should condensation or
frothy oil occur in the gear case).
NPSH values must be observed.
Max. input pressure 145 PSI (10 bar), max. suction head -4.4 PSI (-0.3 bar). Make sure that the
suction pulsation is sufficiently dampened - water
column resonance must be avoided.
Cavitation and/or compression of gases lead
to uncontrollable pressure-kicks which can
ruin pump and unit parts and also be dangerous to the operator or anyone standing nearby.
GIANT Plunger Pumps are suitable for pumping
clean water and other non-aggressive or nonabrasive media with a specific weight similar to
water.
Important!
If the pump is not used for a long
period of time, it is possible the seals (22 & 23)
could become hard or brittle thus causing the
pump to leak when put into operation.
If this is the case, we recommend these seals be
replaced every 4 years.
Before pumping other liquids - especially flammable, explosive and toxic media - the pump
manufacturer must be consulted with regard
to the resistance of the pump material. It is
the responsiblity of the equipment manufaturer and/or operator to ensure that all pertinent
safety regulations are adhered to.

ΔSafety
Rules
A safety valve is to be installed in accordance with
the guidelines for liquid spraying units so that the
admissible operating pressure cannot be exceeded by more than 10%. Pump operation without a
safety valve as well as any excess in temperature
or speed limits automatically voids the warranty.
When the pump is in operation, the drive shaft end
and the coupling must be enclosed by a protective
cover or a coupling bell.
Finally, remember that high pressure operation in a pump system has many advantages. But, if it is
used carelessly and without regard to its potential hazard, it can cause serious injury.
