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

IWAKI MAGNETIC DRIVE PUMPS MD-VMD-F
A wide selection range according to chemical liquids
Outline of the series (50Hz)
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.
