INSTALLATION INSTRUCTIONS

Required NPSH refers to water: Specic
weight 1kg/dm3, viscosity 1°E at maximum
permissible 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 also
be used and the pump run ‘dry’ for 1-2 min­utes for this purpose.

Oil: Use only 8.1 ounces (0.24 litres) of Giant
Oil (p/n 01154) 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 operating hours. In either
case change the oil once per year.

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.

Before any maintenance to the pump takes
place the pressure in discharge line and in

pump must be at zero. Close suction line. Dis-

connect fuses to ensure that the driving motor

is not accidently switched on.

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 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.

Caution! When operating in damp places or

with high temperature uctuations. Should

condensate (frothy oil) occur in the gear box

the oil must be changed immediately.

Keep NPSH under control.

Maximum input pressure 145 PSI (10 bar),
maximum suction head -4.35 PSI (-0.3 bar).
Make sure that suction pulsation is sufciently
dampened - water column resonance must
be avoided.

Safety Rules

Pump operation without 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 %.

Giant Plunger Pumps are suitable for

pumping clean water and other non-agressive
or 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 under all
circumstances 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.

Consult the factory for special requirements that must be met if the
pump is to operate beyond one or more of the limits specied 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:

We recommend a 1.15 service factor be specied when selecting an electric motor as the power source.
To compute electric motor horsepower required, use the following formula: HP = (GPM X PSI) / 1450.
The formula to determine the horsepower required for a gas engine is: HP = (GPM X PSI) / 1150.
The formula to determine the horsepower required for a diesel engine is: HP = (GPM X PSI) / 1250.

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)

Calculating RPM / GPM of Pump:

A pump must be connected to an electric motor or gas or diesel engine with the correct ratio of pulleys
and belts to attain the required speed and GPM. The use of a Variable Frequency Drive (VFD) may also
be used to control the RPM of a properly sized electric motor when variable ows are required.

(Max. Pump RPM / Rated Pump GPM) x Required Pump GPM = Required Pump RPM

To calculate a pulley diameter one (1) pulley diameter and the required pump RPM must be known:
(Pump RPM x Pump Pulley Diameter) / Motor RPM = Motor Pulley Diameter
(Motor RPM x Motor Pulley Diameter) / Pump RPM = Pump Pulley Diameter
