Iwaki MAG Series Stainless Steel Magnet Drive Pumps

Iwaki MAG is a series of stainless steel magnet drive centrifugal pumps with a compact, leak-free design. The pump chamber is sealed by magnetic coupling, so the pump has no shaft seal to leak. The wetted pump parts are made of 304 stainless steel, and the wet bearing is made of SiC (ceramic).

Design

The catalog highlights three features. An open impeller (fitted to the 0.75-2.2 kW models; the 0.37 kW and 0.55 kW models have a closed impeller) is easy to clean. The SiC wet bearing is durable and shows no frictional wear. The simple construction with a single wet bearing makes disassembly and reassembly easy.

Models and typical performance

The series is built on a range of pump sizes (suction bore Rc 1/2 to Rc 1½) and motor outputs from 0.37 kW to 2.2 kW. The 0.37 kW and 0.55 kW motors have a design pressure of 0.4 MPa; the 0.75 kW, 1.5 kW and 2.2 kW motors have a design pressure of 0.6 MPa. The liquid temperature range is -20 to 100 °C, and the standard O-ring is EPDM (PO), with FKM or VMQ as options. The values below are the typical performance points (small-capacity point) given in the catalog for clear water with a specific gravity of about 1.0 and a viscosity below 10 mPa·s.

W5 models are for 50 Hz and W6 models for 60 Hz. Pump performance changes with liquids whose specific gravity and viscosity differ from water; contact us for the specification of your duty point.
