MH, MHI, MHN Series Horizontal Multistage Centrifugal Pumps
The Lubi MH, MHI and MHN pumps are non-self priming,horizontal, multistage, centrifugal pumps.
Motor and pump are close coupled in a convenient and compact design for quick installation in limited space. The pump is fitted with a maintenance-free, mechanical shaft seal. The pumps have axial suction port and radial discharge port and are mounted on a base plate.
These pumps are available in three basic versions:
- MH : Pump stages as well as all moving parts in contact with the pumped liquid are made of stainless steel AISI 304. Discharge casing and suction casing are Grey Iron.Base plate is made of steel. All Grey Iron parts and base plate are CED coated for rust & corrosion prevention.
- MHI : Discharge casing, suction casing as well as all parts in contact with the pumped liquid are made of stainless steel AISI 304.
- MHN : Discharge casing, suction casing as well as all parts in contact with the pumped liquid are made of stainless steel AISI 316.
Salient Features :
- The pump casing shall be of Cast Iron grade FG 260 as per IS 210 / ISO 186 and CF8M Investment Cast have axial suction and radial discharge port.
- The pump shall have fabricated closed type impellers and bowl diffuser casings made out of AISI 304 Stainless steel sheet metal.
- The Pump shaft sealing shall be by mechanical shaft seal of Carbon/Ceramic/NBR/AISI 304 construction suitable for 10 bar pressure rating and water temperature from 0 to +90°C.
- The Pump shaft sealing will be by mechanical shaft seal of Carbon/Ceramic/Viton/AISI 316 Construction suitable for 10 bar pressure rating and water temperature from 0 to +90°C.
