Iwaki MDG gear pumps


Small sealless magnetic drive gear pumps engineered to provide the utmost in quiet and leak-free operation.

Owing to their remarkable efficiency and compact design, MDG pumps are in wide use in hundreds of varied applications, including some of the most sophisticated medical and laboratory equipment.

Sealless Construction

Leak free and sealless, the MDG Series pumps are ideal for incorporation into equipment. The magnet drive mechanism eliminates the troublesome shaft seal replacement.

Outstanding Corrosion Resistance

The liquid end parts are manufactured from SUS316, PTFE, PPS and PEEK. This combination of materials offers extremely high levels of corrosion resistance, thus making the MDG pumps capable of transferring many different aggressive chemical solutions.

High Pressure Gear Rotary System

MDG pumps are characterised by high pressure and low flow rate. Despite its small size, it can attain high pressure to 0.6MPa and vacuum of 5.3kPa.
