The MFI series of types is specially designed to pump sewage, slurry and post-production waste stored in settling tanks located below the floor level.
The MFI pumps by EMM™ are vertical, centrifugal, rotary, single-step pumps with open or closed impeller. What is particularly typical of the MFI pumps is the lack of bearing mounting in the submerged part. The centrifugal elements of the pump are set on a rigid shaft supported by bearings in the part that has no contact with the pumped medium.
The elements of the flow system are usually made of highly alloyed chromium cast iron (white cast iron) characterised by high hardness (approx. 63-65 HRc), very good abrasion and corrosion resistance, however because of a wide range of possible applications, pumps are manufactured in various material versions, depending on application requirements. For production we mainly use cast iron, carbon steel as well as austenitic alloys – acidproof.
The pumps’ design enables the adjustment of clearance between the impeller’s front and the body.
The bearing system does not require additional cooling, as the bearings are smeared with grease.
