IWAKI MAGNETIC DRIVE PUMPS Main material GFRPP Solutions for chemical handling applications

A worldwide best-seller, our high-quality compact magnetic drive pumps Our MD series leak-free compact magnetic pumps are a worldwide best-seller and are used in medical equipment, analyzers, constant-temperature baths and surface treatment equipment for chemical feeding in more than thirty countries worldwide. Leak free Large selection Magnetic drive seal-less pumps are free from leakage problems The MD series comprises 50 models. The high-head type(MD-Z), and the need for seal replacement. This feature and their com- the high flow type(MD-X) and threaded connection type(MD-M) pact nature make...

IWAKI MAGNETIC DRIVE PUMPS MD The centrifugal pump is driven by a pair of magnets which are incorporated in the impeller and motor shaft. The sealless pump structure eliminates shaft seals such as conventional mechanical seals because the pump chamber is shielded by the casings and the impeller is operated by the magnets. The combined coupling torque of the drive magnet and impeller magnet gives sufficient driving power against the motor torque. Driven magnet Drive magnet Operating Principle md-55*70*100 E • Max Discharge capacity 40 - 135 l/min • Max Discharge head 5.6 - 14.3 m

The MD series has GFRPP wet ends. Hose connections and threaded connections are available. A large selection of models offer a wide flow range of 5.5-135L/min.

IWAKI MAGNETIC DRIVE PUMPS Large capacity type High-head type Motor Drive magnet The 6- or 8-pole high power ferrite magnet drives the impeller through the rear casing. O ring Rear casing GFRPP single-piece rear casing has the bearing mounted at the bottom to support the spindle. Spindle Front casing Hose or threaded connections can be selected according to application. Also union joints can be installed on threaded connection models. Note: MD-6, 6Z and 10 models do not have the bearing. The ferrite magnet is encapsulated into the impeller. For rotating spindle models, an alumina ceramic spindle...
