IWAKI MAGNETIC DRIVE PUMPS MD-VMD-F

Compliant with highly corrosive / viscous liquidsHigh-end compact magnetic drive pumpsMost chemicals can be handled including strong acid/alkaline.

The combination of the MD-F series with CFRETFE wet ends

and the MD-V series with CFRPVDF wet ends covers most

chemicals including strong acid/alkaline.

The MD-F series is designed to pump highly viscous liquids

such as strong acid. Three types of impellers are selectable

according to liquid viscosity.

Magnetically-driven seal-less pumps are free from leak problems

and the need of seal replacement. This feature and its compact

nature offer the best fit in built-in applications.

The pump unit is comprised of a small number of subunits, so

that maintenance is significantly eased.

High corrosion-resistance Viscosity responsiveness Leak free Easy maintenance

Hyperbaric/High-compression types are available.

Motor

Drive magnet

O ring

Spindle

The 6- or 8-pole high power ferrite magnet drives the impeller over the rear casing.

ImpellerCFRETFE single-piece closed impeller.

Three impeller types (X/Y) are available according to speci�c gravity.

Front casing

For the MD-V, the ferrite magnet is encapsulated into the CFRPVDF impeller. For the rotating spindle type, an alumina ceramic spindle is integrally molded with the impeller.

CFRETFE injection mold of the safety thread connection type

CFRPVDF hose connection is available as well as thread connection. Also union joints can be installed for the thread connection types.

Note: For the 15RV, the thread connection type is not available.

Rear casingCFRETFE single-piece rear casing of the MD-F and CFRPVDF single-piece rear casing of the MD-V. The bearing is placed at the bottom, supporting the spindle.

The centrifugal pump is driven by a pair of magnets which are incorpo-

rated 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 suf-ficient driving power against the motor torque.
