14.2 Cleaning in the CIP circuit
14.3 Manual cleaning
Manual cleaning of the pump can be performed after complete dismantling of the pump.
Pay attention to parts sensitive to breakage!!
If the pump is stopped during the process and opened for the purpose of cleaning or checking,
the responsible fitter or electrician must be notified to undertake suitable measures so that the pump
cannot be put into operation (remove fuses, notify electrician).
The pump may also never be put into operation if the housing cover is removed. Should the pump
not yet be connected to the piping system, then reliable care must be taken that the drive machine
cannot be switched on.
Observe the accident prevention regulations!!
14.4 Sterilization
Sterilisation of the pump with standard equipment is possible up to 110°C only in standstill!
In the case of special equipment of the pump or higher temperatures, please always firstly consult the manufacturer!
15 Oil change
The oil must be changed once yearly or every 1500 operating hours for
the pumps of the serie MR 160. The standard operation for changing oil
would be to loosen all four bolts on the bearing housing cover (Pos. 21)
and all parts should be removed (bolts and cover). At this point the used
oil can be drained. After that the bearing housing cover has to be
replaced and the bolts would be retighten. The oil sight glass in the
bearing block should be filled up to the middle. (ca 0.3 Liter). Please use
the following oil grade or similar:
***(Standard first filling of the WATSON-MARLOW MasoSine-
PUMPS)***
Klüberoil 4 UH 1-220 N (lubricating oil for the food and pharmaceutical
industry)
Our standard first filling is only suitable for
temperatures above –10° C.
If you come below –10° C you must replace the oil !
