Start Up; Closing Down - M&C MP Series Instruction Manual

•
Push the hose/tube onto the supporting nipple in the threaded joint.
•
Tighten the sleeve nut by hand.
The tube is now mounted in a non-slip and pressure-resistant manner.
Connection fittings for DN 4/6 or DN 6/8 are optionally available from M&C.

START UP

Before commissioning, the plant- and process-specific safety measures must be observed!
The relevant safety regulations and measures must be observed for the media to be pumped. Before using a me-
dium, the compatibility of the materials of the pump head, diaphragm and valves with the medium must be
checked (for pump materials: see technical data). The following steps must be carried out during initial commis-
sioning:
•
The pump must not start against pressure or vacuum. When it is switched on the pressure in the suction
and pressure lines must be atmospheric. This must be so even when the pump restarts after the power
have been cut off for a short period.
•
The maximum permissible operating pressure (see technical date) must not be exceeded, even when the
flow is restricted.
•
To prevent the maximum permissible operating pressure being exceeded, restriction or control of the air
or gas flow should only be carried out in the suction line.
•
If restriction or control of the air or gas flow is made on the pressure side, ensure that the maximum per-
missible operating pressure is not exceeded.
•
When the pump is at a standstill the inlet and outlet must be at normal atmospheric pressure.
•
Diaphragm and valve plates are the only parts subject to wear. Wear is usually indicated by a drastic re-
duction in the pneumatic performance. When replacing parts proceed as described in chapter 18.
• Ambient conditions: see technical data.

CLOSING DOWN

Note
No further special measures need to be taken when decommissioning.

The area in which the pump is situated when not in use must be kept free of
frost at all times!
