Iwaki MDT Series Magnetic Drive Turbine Pumps

The Iwaki MDT series is a plastic magnetic drive turbine pump for small flows at high pressure. The wetted parts are metal-free (GFRPPS, CFRPPS, CFRPEEK, alumina ceramic and carbon), and the seal-less construction means no leakage from a shaft seal and no seal replacement. The pump is small enough to be built into equipment such as laser and X-ray systems. Mikron Proses (Üsküdar, Istanbul) supplies Iwaki MDT pumps in Turkey and provides application consulting on pump selection.

Compact body, high pressure

Despite its small size, the MDT delivers a discharge pressure of up to 0.35 MPa. It can also be used with negative pressure on the suction side: the catalogue gives an attained degree of vacuum of 8.00 kPa (absolute) for L types and 9.33 kPa (absolute) for H types. Because no metal is used in the wetted parts, the pump can handle various chemicals, including acid and alkaline solutions. The maximum liquid viscosity is 2 mPa·s, and liquids containing slurry cannot be handled.

L and H temperature classes

The series comes in two sizes, MDT-15 and MDT-20, each in two temperature classes: the L type for liquids from -20 to 65 °C and the H type for -20 to 95 °C. The model code gives the pump size, the temperature class (L or H), the bearing material (C for carbon, D for SiC or siliconized graphite), the connection (A for R1/2, B for 1/2 NPT) and the power source. Performance data are for clear water at 25 °C; other liquid properties and temperatures can change the performance, and the manufacturer asks to be consulted for liquids below 0 °C.

Where the MDT series is used

The manufacturer names cooling circuits of laser and X-ray systems and temperature control systems as typical uses, together with equipment that needs a metal-free construction for acid or alkaline liquids. Please send us your liquid, temperature and flow requirement so that we can check the match.
