Pump - Mono MS
Mono have been manufacturing pumps since 1935. The design is what's known as a progressive cavity pump, being a single helix rotor operating within a twin helix stator. In very simplistic terms it can be thought of as being similar to an Archimedean spiral pump.
The MS pump has been in manufacture for at least 40 years and spare parts are still available.
The design is self priming and can be considered as a positive displacement pump. It is capable of pumping a large range of media including slurries and small entrained solids, although the latter will obviously enduce premature ware. Different stator materials are available and the writer has had a viton stator pumping bio and vegatable oil in an MS pump for nearly five years at the time of writing with no noticible adverse effects.
The pumps ability to pump viscous liquids makes it ideal for pumping WVO and semi-solid fats.

- Stator material ... nitrile rubber (standard) but various available including Viton.
- Weight ... 16kg
- Flow at 1450rpm ... 12.5 L/min @ 0 bar - 5.3 L/min @ 3.5 bar.
