- Maximum suction pressure :

• In normal use, the suction pressure must be higher than the
required NPSH and less than 1,5 barg (21,75 psig).

• Pump stopped, the pressure must not exceed 6 barg
(87 psig).

- Acceptable maximal differential pressure :

• C12 A...........................9 bar (130,5 psi)*

* When the pump works with an inlet gauge pressure less than zero, the

maximum outlet pressure will be calculated as if the inlet pressure is
equal to zero.

STANDARD

STANDARD

The C Series pump is a selfpriming 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.

2.1 Orientation of the pump ports

The discharge port may be oriented in various positions.

If the port positions needs to be changed at any time,
see the corresponding paragraph.

2.2 Direction of rotation

When looking at the shaft, the rotation will be clockwise.
When looking at the front cover, the direction of rotation
will be anti-clockwise. An arrow situated on the bearing
housing indicates the correct direction of rotation.

Verification of the correct rotation direction :

Turn the pump the wrong way is not dangerous for the
pump.

2.3 Protection of the pump installation

• For ease of maintenance, it is a good idea to place iso­lation valves before and after the pump. The sizing of
these valves must correspond to the diameter of the
pipes.

• Before any start-up, during operation or complete stop­ping of the pump, make sure the valves are open.

• During stop periods, with the pump full of product,
either the suction or discharge circuit must be left open
to enable expansion or contraction of the pumped pro­duct through reheating or cooling. If this instruction is
not complied with, The bellows may be damaged and
lead to premate failure.

• The bearing must be ventilate at all times, therefore the
breather mounted on the bearing must be re-used.
Never put the bung on

.

• In case of flodded suction, it is possible to install a
liquid detector in the place of the transmission breather
(see § options). This detector will enable the user to be
informed in the case of failure of the bellows. In the
case of detection, the installer must make sure the
pump is stopped and the isolating valves are closed.
Non compliance with this instruction can lead to the
pumped product being spilt outside the pump.

• It is possible to have a puncture detection system with
double-walled bellows : an inert gas is maintained under
pressure between the 2 walls and said pressure is per­manently monitored. A signal is dispatched immediately
should a wall become punctured (see § OPTIONS).

• The stop time may lead to cooling of the product in the
pump and therefore to an increase in viscosity. If this is
the case, we recommend re-starting the pump at a
speed adapted to this new viscosity (starting pump).
Once the product arrives in the pump at the installation
definition temperature, the pump may run at the speed
specified for this application.

NOTICE
C-Series pumps remains drainable whatever
position is chosen for the inlet port, but the
outlet port must be at the bottom (position 4)
to keep the self-draining capability.
