Iwaki MD-F Series CFRETFE Magnetic Drive Pumps

Iwaki MD-F is a series of sealless (magnetic drive) process pumps with CFRETFE wetted parts. CFRETFE is carbon fiber reinforced ETFE. According to the datasheet, the MD-F, together with the MD-V (CFRPVDF wetted parts), covers a wide range of chemicals, including strong acid and alkaline liquids. The MD-F is also designed for liquids of higher viscosity such as strong acid.

Model family and impeller choice

The series has four body sizes: MD-15F (9-10 L/min, 3-4.1 m), MD-30F (10-13 L/min, 6-8 m), MD-55F (60-65 L/min, 5.4-7.8 m) and MD-100F (115-125 L/min, 8.5-10.5 m, the largest body, with the maximum flow and head of the series). Each model is offered with an X (low specific gravity) or a Y (middle specific gravity) impeller, so the same body can be matched to liquids of different density. The MD-55F and MD-100F are also available with IEC frame motors (220-240 V single phase or 400/440 V three phase).

Model	Impeller	Max. capacity	Max. head	S.G. limit	Connection
MD-15F	X / Y	10 / 9 L/min	4.1 / 3 m	1.2 / 1.9	NPT 1/2
MD-30F	X / Y	13 / 10 L/min	8 / 6 m	1.5 / 1.9	NPT 1/2
MD-55F	X / Y	65 / 60 L/min	7.8 / 5.4 m	1.3 / 2.0	R1
MD-100F	X / Y	125 / 115 L/min	10.5 / 8.5 m	1.2 / 2.0	R1

Materials and limits

The impeller, the front casing and the rear casing are made of CFRETFE; the spindle, the thrust ring and the bearing are made of SiC (silicon carbide ceramic). The O-ring is FKM as standard and EPDM on request. The liquid temperature is 0-80 °C and the viscosity limit is 30 mPa·s at a specific gravity of 1.0. The ambient temperature is limited to 0-40 °C. The unit consists of a small number of subunits, which eases maintenance, and its compact, sealless structure suits built-in applications.
