The MD/ME/MDV is a configured, ring section, multistage pump specifically designed for high pressure membrane feed service in Zero Liquid Discharge of concentrated salt and seawater reverse osmosis applications. It is also used for any other high pressure application with clean liquids.
It is mainly used in the following applications:
Seawater Reverse Osmosis (SWRO)
Zero Liquid Discharge of concentrated salt water
Boiler Feed Water
Clean Water Pumping Stations
Any other high pressure application for cleaning liquids
Casing | adopts segmental radial section structure, larger inlet and outlet, optimized inlet flow, low noise level. Higher allowable nozzle force and torque; Radial fully symmetrical hydraulic design to minimize radial force, improve efficiency and prolong the effective life of the rotor and other parts; |
Flanges | Suction and DischargeMD multistage ring section pump, its suction and discharge can be set on the side or top according to the needs of the user's piping, including the typical side inlet and outlet configuration; MDV multistage ring section pump, its suction and discharge can be relative position every 90°； ME multistage ring section pump, its suction is end suction, and the discharge can be on the side or top. The drive ends of MD/ME multistage ring section pump use radial suction and discharge flanges to ensure that no disassembly pipe is required for maintenance of mechanical seals and bearings |
Stage Casing and Diffuser | the one body design and manufacturing of the stage casing and diffuser reduces the mating surface, so as to improve the precision of coordination, and the stability of operation and to extend the life. |
Impeller | superior hydraulic efficiency and high energy saving |
Shaft | the bigger shaft has the minimum deviation under the maximum heavy load to ensure the running parts on the shaft work well; The pumps run more stably, bearings and mechanical seals last longer, reducing maintenance and repair costs |
Bearing House | the larger bearing chamber is lubricated with dilute oil and can also be lubricated with grease |
Axial Force | the balanced axial force of the balancing drum is adopted |
Shaft Seal | mechanical seal for hexadecimal shaft seal; optional packing for the special application |
Installing | side suction horizontal installation for MD multistage ring section pump; end suction horizontal installation for ME multistage ring section pump; side suction vertical installation for MDV multistage ring section pump |
Parts | the modular design of currency parts, high degree of universalization, reduce spare parts inventory |
