Iwaki MD-V Series CFRPVDF Magnetic Drive Pumps

Iwaki MD-V is a series of sealless (magnetic drive) process pumps with CFRPVDF wetted parts. CFRPVDF is carbon fiber reinforced PVDF. The impeller is driven through a pair of magnets, so there is no shaft seal that can leak and no seal to replace. According to the datasheet, the MD-V (CFRPVDF wetted parts), together with the MD-F series (CFRETFE wetted parts), covers a wide range of chemicals, including strong acid and alkaline liquids.

Model family and performance range

The series has seven body and impeller combinations: MD-6KV (8.0 L/min, 1.0 m), MD-15RV (16 L/min, 2.4 m), MD-20RZV (10 L/min, 4.9 m, high-head type), MD-30RV (32 L/min, 3.8 m), MD-30RZV (15 L/min, 8.0 m), MD-70RV (86 L/min, 6.7 m, the maximum capacity of the series) and MD-70RZV (40 L/min, 14.3 m, the maximum head of the series). The letters “RZ” mark the high-head type and “R” the standard type.

Model	Max. capacity	Max. head	Motor output
MD-6KV	8.0 L/min	1.0 m	5 W
MD-15RV	16 L/min	2.4 m	10 W
MD-20RZV	10 L/min	4.9 m	20 W
MD-30RV	32 L/min	3.8 m	45 W
MD-30RZV	15 L/min	8.0 m	45 W
MD-70RV	86 L/min	6.7 m	150 W
MD-70RZV	40 L/min	14.3 m	180 W

Connection options depend on the body size: the MD-6KV and the MD-15RV have 14 mm hose connections; the MD-20RZV and the MD-30 models offer G3/4 threaded connections in addition to hoses; the MD-70 models offer threaded connections up to G1. The threaded connection type is not available for the MD-15RV and the MD-6KV.

Materials and limits

The impeller and the front casing are made of CFRPVDF, the spindle and the thrust ring of alumina ceramic, and the bearing of PTFE or CFRPPS. The O-ring is FKM as standard and EPDM on request. The liquid temperature is 0-80 °C, the viscosity limit is 30 mPa·s at a specific gravity of 1.0, and the ambient temperature is limited to 0-40 °C.

The pump unit consists of a small number of subunits, which eases maintenance, and its compact, sealless structure suits built-in applications.
