Pipe alignment and supporting
Pump must not support piping nor endure stress resul-
ting from piping weight or dilatation effects. For latters,
expansion loops should be included.
Pipe equipment
• Place valves close to the pump to avoid draining pipe
during maintenance operations. Preferably select full
bore ball or butterfly valves.
Pressure connections on pump suction and discharge
are recommended for settings and controls.
Make sure piping, vessels valves and other installation
devices are carefully cleaned before mounting.
• MOUVEX pumps are self priming. However, if line
emptying should be avoided and/or if suction lift is high,
a foot valve can be added.
• If pumped liquid presents a risk of in pipe solidification
and potential dilatation, low points on the pipe should
be avoided or equipped with drain valve.
• If installation is heated, it must be designed so that fluid
dilatation can evacuate through piping. Therefore fluid
contained in piping must be heated before fluid contained
in the pump. Also check that a heated pump is not iso-
lated by closed valves.
The Micro C pump is a self-priming volumetric PD pump.
Therefore, the pump must not run on a circuit with a
closed valve. This is valid both for the suction circuit and
for the discharge circuit.
The pump is designed to be attached to the end of a
motor; during assembly ensure that the half couplings
are tightly and securely closed.
2.2 Orientation of the pump ports
The suction port and the discharge port may be oriented
in various positions.
If the port positions need to be changed at any time, see
the corresponding paragraph.
2.3 Direction of rotation
When looking at the shaft, the rotation will be clockwise.
An arrow situated on the lantern ring indicates the cor-
rect direction of rotation.
Verification of the correct rotation direction :
Turning the pump the wrong way is not dangerous for
the pump.

NOTICE
Micro C pumps will be drainable only if the
inlet port is pointed up (position 2) and the
outlet port at the bottom (position 4).
