The MD series is one of the most sold pumps in the world!

The pumps of the MD series are compact, leakage-free magnetic drive pumps, which are highly appreciated worldwide. Due to the compact design, the MD series is ideally suited for installation in machines and equipment. Applications include automatic photo processors and a wide range of analysis equipment. The pumps can handle almost all chemical liquids

Leakage free

The sealless pumps are magnetically driven. This means that no leakage can occur at the drive. Due to their compact design they are ideal for installation in machines and equipment.

Model variety

To offer maximum flexibility for applications, the MD series now includes 50 models, more variants than ever before. In addition to the standard versions, there are models for more head (MD-Z), more flow rate (MD-X), and from the MD-15 on also with threaded connections (MD-M).

High corrosion resistance
GFRPP (glass fibre reinforced polypropylene) Wet part of the MD Series is resistant to most chemicals.
Easy maintenance
Due to the simple construction with only a few integrated parts, installation and maintenance are unproblematic.

Principle of operation

A pair of magnets, which is connected to the impeller or motor shaft, drives the pump. The seal-less design eliminates the need for maintenance on the shaft/mechanical seal. The pump chamber is completely shielded by the housing construction. The frictional connection of the magnetic coupling ensures excellent transmission of the motor torque.
