The North Ridge MN series progressive cavity dosing pump is specifically designed to transfer viscous and non-viscous fluids with or without solids in suspension at very low and precise flow rates while still maintaining a high pressure.
This helical rotor dosing pump creates extremely low vibrations and pulsations, it is therefore excellent at pumping shear sensitive fluids; for example paints, pigments, slurries, creams, shampoo, mayonnaise and polymers to name a few.
The casing of this positive displacement dosing pump can be constructed from various materials including cast iron, stainless steel 304, stainless steel 316 and duplex stainless steel. The rotor is available in stainless steel 420, 304, 316, and duplex, while the stator can be supplied in NBR, EPDM, FKM, HNBR, and PTFE. Such a wide range of material choices makes this pump series extremely versatile and capable of pumping a vast range of fluids.
Sealing options for this helical rotor dosing pump include single mechanical seal and double mechanical seal.
This progressive cavity dosing pump is Atex certified for handling flammable fluids and installation in non-safe areas.
This progressive cavity dosing pump is ideal for many applications in the industrial and marine markets, including; oil transfer, sewage transfer, bilge water transfer, waste water transfer, sludge transfer, acids, lime milk, inks, paint, marine, and agriculture.
This dosing pump is also available in a food-grade version constructed from polished stainless steel 316 and installed with a food-grade stator. Suitable food applications for the MN series include fruit juice pulp, beer, fruit paste, grapes, grape paste, wine and edible oils.
