INSTALLATION INSTRUCTIONS
Required NPSH refers to water: specic weight
1kg/dm3, viscosity 1°E at maximum permissible
revolutions.
Operation and Maintenance
Check oil level prior to starting and ensure a
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 also be used
and the pump run “dry” for 1-2 minutes for this
purpose.
Oil: Use only SAE 20W-50 (p/n 01153). Use
7.5 uid ounces (0.22 L) for short crankcase
covers and 9.0 uid ounces (0.27 L) for extend-
ed crankcase covers.
Initial change after 50 operating hours and then
every 500 operating 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.
Keep NPSH under control.
Maximum input pressure 145 PSI (10 bar),
maximum suction head -4.35 PSI (-0.3 bar).
Make sure suction pulsation is sufciently
dampened - water column resonance must be
avoided.
When the pump is in operation, the drive shaft
end and the coupling must be covered up by
either a contact-protector or by a coupling bell.
Pressure in discharge line and in pump must
be at zero before any maintenance to the
pump takes place. Close up 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 preven air, or an air-water mixture
being absorbed and to prevent cavitation occurring, the pump NPSHR 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 standing nearby.
Giant Plunger Pumps are suitable for pumping clean water and other non-agressive or
abrasive media with a specic weight similar to
water.
Before pumping other liquids - especially
inammable, 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 manufacturer
and/or operator to ensure that all pertinent
safety regulations are adhered to.
Safety Rules
Pump operation witout safety valve as well
as any excess in 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
maximum admissible operating pressure can
not be exceeded by more than 10%.

Consult the factory for special requirements that must be met if the
pump is to operate beyond one or more of the limits specied above.
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 necessary
for the proper assembly sequence.
HORSEPOWER RATINGS:
The rating shown are the power requirements for the pump. Gas engine power outputs
must be approximately twice the pump power requirements shown above.
We recommend a 1.15 service factor be specied when selecting an electric motor as the
power source. To compute specic pump horsepower requirements, use the following
formula:
HP = (GPM X PSI) / 1450
