Installation
Mechanical installation
Placing the pump above ground is generally a
convenient way of establishing a water or rainwater
supply.
Place the pump as close as possible to the water
supply to make the suction pipe as short as possible.
If a hose is used as suction pipe, it must be non-
collapsible. Fit a strainer to the suction pipe to prevent
solids from entering the pump.
The pump must be installed on a plane surface and
fixed so that it cannot be displaced during startup and
operation. The inlet direction must be horizontal.
The pump should be installed with easy access for
inspection, maintenance and service.
The pump should be installed in a well-ventilated
location.
Suction pipe
If the pump is to pump water from a well, borehole or
similar, always fit a non-return valve on the suction
pipe of the pump.
Install the suction pipe in such way that bends, air
pockets and any unnecessary restrictions to the flow
are avoided. See fig. 2.
Fig. 2 Pipework recommendations
Long suction pipes affect the performance of the
pump. The diameter of the suction pipe must not be
smaller than that of the suction port. When the suction
pipe is longer than 32 ft.(10 meters) or the suction lift is
greater than 13 ft.(4 meters), the diameter of the
suction pipe must be larger than that of the suction
port.
The time from when the pump is started until it delivers
water depends on the length of the suction pipe and on
the suction lift. Do not allow the pump to run for more
than five minutes before it delivers water as the heat
generated will damage the pump.
Operating conditions
The maximum time of operation against a closed
discharge valve is limited by the liquid temperature
which must not exceed +104 °F (+40 °C).
The maximum inlet pressure depends on the pump
head at the actual duty point. The sum of the inlet
pressure and the pump head must not exceed the
maximum system pressure.
Electrical installation
The electrical connection and protection should be
carried out in accordance with local regulations.
• One-phase standard pumps incorporate thermal
protection and therefore require no external
protection.
• One-phase CMBE pumps require no external motor
protection. The variable-speed motor incorporates
thermal protection against slow overloading and
blocking.
The electrical installation of the pressure control unit
must be carried out so that the enclosure class is
maintained.
