Sustained efficiency and uptime

An improved uptime and sustained efficiency across your product’s entire lifecycle is important to us.

Our extensive range of pumps cover flows of up to 13,500 m3/h. With inlet sizes ranging from 250 mm to 900 mm with either metal or rubber lining, we can ensure that you will always find the correct mill discharge pump for your process needs.

The hydraulic design of MD Series pumps is consistent across the entire range and reduced impeller overhang restricts shaft deflection across a wide range of flows.

Our experts are always ready to assist you in everything from pump selection to maintenance and services.

Latest in wear technology

Metso MD series horizontal mill discharge slurry pumps are known for their durability. 

Our pumps offer latest in wear technology with usage of high-performance materials with excellent resistance to abrasion and erosion. Special emphasis has been placed on components that have to withstand exceptional wear from coarse heavy solids and flow turbulence.

An oversized robust steel shaft and extra thick casings and liners are just some of the heavy-duty components equipped with the MD series pumps.

Modular and compact design

The modular design ensures easy interchangeability of all metal and rubber parts. The back pull-out features an optional maintenance slide base for fast, easy and safe inspection.

Maintenance friendly construction together with the durability of critical parts result in long service intervals and short maintenance shutdowns.

Wide range of complimentary products

Extended portfolio of complimentary products includes slurry hoses, valves, pipes and innovative sealing solutions.

EnviroSet™ gland has been specifically developed to control the internal stuffing box environment and reduce water consumption.

Metso MD Series slurry pump is easy to operate and maintain.
