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 fittings (par-
ticularly 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.
Caution! When operating in damp places or with
high temperature fluctuations. 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), maxi-
mum suction head -4.35 PSI (-0.3 bar). Make sure
that suction pulsation is sufficiently dampened -
water column resonance must be avoided.
Installation/Putting into Operation
To Turn Drive Shaft to the Other Side
Remove the valve casing.
Turn the seal adapters (20) by 180° also so that
the leakage holes are underneath.
Remount valve casing rotated 180°.
Interchange plug (5) and oil dipstick (2) wtih each
other.
Turn crankcase cover (3) by 180°.
Direction of pump rotation
When looking at crankshaft with valve casing
mounted on left-hand side, counterclockwise
direction of rotation.
When looking at crankshaft with valve casing
mounted on right-hand side, clockwise direction of
rotation.
Suction line filter
Recommended mesh size 150 µm.

Safety Rules

Pump operation without safety valve as well as any
excess in temperature or speed limits, automati-
cally voids the warranty . The safety valve must be
regulated in accordance with the guidelines for liquid
spraying units so that the maximum admissible op-
erating pressure can not be exceeded by more than
10 %.
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. Disconnect fuses to en-
sure 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.
Giant Plunger Pumps are suitable for
pumping clean water and other non-agressive or
abrasive media with a specific weight similar to
water.
Before pumping other liquids - especially inflam-
mable, 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 re-
sponsibility of the equipment manufacture and/
or operator to ensure that all pertinent safety
regulations are adhered to.
