Oil change
In the case of the pumps of the series
MR120, MR125, MR130, MR135, MR150
the oil viewing glass (Pos.
27) in the bearing housing (Pos. 11) must be checked every day for damage and that there is enough oil in the power frame
component, in particular every time before the pumps are used. The oil viewing glass in the bearing housing must always be
filled up to the middle. Please use the following oil type that is applicable for your application! If the pump is to be used in an
area that is combustible where ATEX applies, the oil viewing glass is replaced by a screwed plug.
Standard first filling of Watson-Marlow MasoSine
Pumps
• For –10°C to 60°C
Klüberoil 4 UH 1-220 N (lube oil for the food and pharmaceutical industry)
Oil grades for ex-zones

Klüberoil 4 UH 1-220 N (lubrication oil for the food and pharmaceuticals industries)
Filling volumes
MR120 approx. 0,2 litre MR125 approx. 0,25 litre MR130 approx. 0,25 litre
MR135 approx. 0,3 litre MR150 approx. 0,5 litre MR160 approx. 0,5 litre
Heating and Cooling Option
Special versions of MasoSine
MR120, MR125, MR130, MR135, MR150
pumps can be heated or cooled to
provide the cor-rect temperature for your process - pumping chocolate or ice cream, for example
—by passing fluid at the tem-
perature required through crescent-shaped channels in the pump housing and the front housing. The pump has 1/4in or 1/8in
connections on two sides through which the heating or cooling agent flows. The position of the connections varies depending on
the model. Counter pressure should not exceed 1 bar.
Note:
Most pumps can be retro-fitted to allow heating and cooling.
Note:
The connections on the front cover may hinder some maintenance work at the pump. In most cases, the heating / cooling
of the pump housing is sufficient. Maintenance is not hindered by the connections..
Note:
If a heater is used to maintain a raised temperature, that temperature must be approved by MasoSine.
