Performance data for intermittent operation, data for
continuous operation on request.
For information on intermittent operation and
calculating of the performance data, see the Giant
assembly instructions.
NPSHR / Inlet pressure
Required NPSH refers to water (at 68 °F or 20 °C) at
maximum permissible pump speed.
Maximum inlet pressure: 29 PSI (2.0 bar).
Level of noise emission
Emission sound pressure level ≤93 dB(A)
2. Fields of application
The fields of application of these pump types
correspond to the specifications in the assembly
instructions of Giant pumps.

5. Installation/Putting into Operation
5.1 Shaft protector
When the pump is in operation, the open shaft
end must be covered up by shaft protector (21),
the driven shaft side and coupling by a contact-
protector.
To cover the exposed crankshaft end, mount the
shaft guard (21) together with the holder (21A) onto
the bearing cover (14) and secure with bearing
cover screws (17).
5.2 Direction of pump rotation
Set the direction of rotation of the drive unit
according to the direction of rotation arrow on the
crankcase.
5.3 Suction line filter
Recommended mesh size 50 μm.
6. Operation
Maximum operation pressure is attainable at 600 -
800 rpm. If the speed is reduced further, the pump
pressure must be reduced in the same proportion
to ensure sufficient gearbox lubrication.
6.1 Discharge Line
The pump comes with two special lens seals (62)
which have to be inserted in to the discharge ports
of the pump. One of the two ports is to be closed
with the included plug (63).
The 1/2” BSP high-pressure hose connection for
the discharge line must be constructed as per the
below drawing to ensure that together with lens
seal (62) the discharge line is completely sealed.
We offer the high-pressure connection (05361)
with UNF 9/16’’ female threads for high-pressure
fittings.
The two 1/2” BSP connections on the top side of
the valve casing are closed off with plug (60) and
copper seal ring (61). These two connections are
for the optional fitting of a pressure gauge and/or
safety valve such as our 23140.
Should a pressure gauge or safety valve be
installed, the copper ring (61) must remain in the
bore.
Pressure gauges with a 1/2” BSP connection have
the appropriate contour so that the copper ring sits
properly.
The alignment of the pressure gauge cannot be
determined exactly after tightening.
We offer the double nipple (05362) for mounting
the 23140 pressure relief valve.
