INSTALLATION INSTRUCTIONS
Safety 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.
Pressure in the discharge line and pump must
be at zero before any maintenance to the pump
takes place. Close suction line. Disconnect
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 before starting the pump.
In order to prevent air, or an air-water mixture
being absorbed and to prevent cavitation
occuring, the pump NPSHR suction head and
water temperature must be respected.
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-agressive or non-
abrasive media with a specic weight similar to
water.
Before pumping other liquids - especially
inammable, explosive and toxic media - the
pump manufacturer must be consulted with
regard to the resistance of the pump material.
It is the responsibility of the equipment
manufacture and/or operator to ensure that all
pertinent safety regulations are adhered to.
Required NPSH refers to water (specic
weight 1kg/dm3, viscosity 1°E) and maximum
premissible pump revolutions.
Operation and Maintenance
Check oil level prior to starting and ensure
trouble-free water supply.
Important! If there is a danger of frost, the
water in the pump and in the pump ttings
(particularly the unloader valve) must be
emptied. The second discharge port can be
used and the pump run “dry” for 1-2 minutes for
this purpose.
Oil: Use only 27.1 uid ounces (0.8 liters) of
ISO VG 220 GL4 (e.g. Aral Degol BG220) or
SAE 90 GL4 gear oil (Giant p/n 01154).
Initial oil change after 50 operating hours and
then every 500 hours,after 1 year if used less.
Caution: When operating in damp places or
with high temperature uctuations, oil must
be changed immediately [should condensate
(frothy oil) occur in the gear box].
NPSH values must be observed.
Maximum input pressure 145 PSI (10 bar),
maximum suction head -4.35 PSI (-0.3 bar).
Make sure that suction pulsation is su󰀩ciently
dampened - water column resonance must be
avoided.
Important! If the pump is not used for a long
period of time, it is possible the seals (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.

P470 HORSEPOWER REQUIREMENTS
NOTE:
In order to drive the pump from the side opposite the present shaft extension, simply remove the
valve casing from the crankcase and rotate the pumps 180 degrees to the desired position. Be
certain to rotate the seal case (item #20) as well, so that the weep holes are down at the six o’clock
position. Exchange the oil ll and the oil drain plugs, also. Refer to the repair instructions as neces-
sary for the proper assembly sequence.
Horsepower Ratings:
Horsepower ratings shown are the power requirements for the pump. Gas engine power outputs must
be approximately twice the pump power requirements shown above. We recommend that a 1.15
service factor be specied when selecting an electric motor as the power source. To compute specic
pump horsepower requirements, use the following formula: (GPM X PSI) / 1450 = HP
For the Application of a Hydraulic Motor:
To Determine the Torque of a Hydraulic Motor -- (GPM x PSI x 36.77) / RPM = Torque (in-lbs)
