INSTALLATION INSTRUCTIONS
Pressure in discharge line and in pump must
be at zero before any maintenance to the
pump takes place. Close up suction line. Dis-
connect fuses to ensure that the driving motor
does not get switched on accidentally.
Make sure that all parts on the pressure side of
the unit are vented and refilled, with pressure
at zero, before starting the pump.
In order to prevent air, or an air/water-mixture
being absorbed and to prevent cavitation oc-
curring, the pump-NPSHR, positive suction
head and water temperature must be kept
under control.
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 stand-
ing nearby.
Giant plunger pumps are suitable for pump-
ing clean water and other non-aggressive or
abrasive media with a specific weight similar to
water.
Before pumping other liquids - especially
inflammable, explosive and toxic media
- the pump manufacturer must under all
circumstances be consulted with regard to
the resistance of the pump material. It is
the responsibility of the equipment manu-
facturer and/or operator to ensure that all
pertinent safety regulations are adhered to.
Required NPSH refers to water: Specific
weight 1kg/dm
3
, viscosity 1 °E at max. per -
missible revolutions.
Operation and Maintenance
Check oil level prior to starting and ensure
trouble-free water supply.
Oil: Use 33.8 fl. ounces (1.0 liters) of Giant’s
part number 01154 or ISO VG 220 GL4 (e.g.
Aral Degol BG220) or SAE 90 GL4 gear oil.
Initial change after 50 operating hours and
then every 500 hours, after 6 months opera -
tion in any case.
Caution when operating in damp places or
with high temperature fluctuations. Oil must
be changed immediately, should condensate
(frothy oil) occur in the gear box.
Keep NPSH under control.
Max. input pressure 145 PSI (10 bar), max.
suction head -4.35 (-0.3 bar).
Safety Rules
Pump operation without safety valve as well
as any excess in the temperature or speed
limits automatically voids the warranty. The
safety valve must be regulated in accordance
with the guidelines for liquid spraying units so
that the admissible operating pressure can
not be exceeded by more than 10%.
When the pump is in operation, the open
shaft end must be covered up by shaft pro-
tector (21), the driven shaft side and coupling
by a contact protector.
