Chemically resistant self-priming magnetic drive pumps which can tolerate abnormal operation he SM-F is a horizontal self-priming magnetic drive pump made from fluororesin. Our original self-radiation structure (Patented) enhances resistance to dry running, cavitation, and closed-discharge operation. In addition, the use of standard motors extends the range of application. SM-F43 SM-F441 1 1
IWAKI SELF-PRIMING MAGNEIC DRIE PUMPS SM-F Excellent corrosion resistance he casings, impeller assembly and magnet capsule are made of fluororesin(cfrefe). Other wet-end parts are made of highly corrosion resistant materials such as carbon, ceramic and the like. he pumps can handle almost type of chemicals including strong acid/alkali. Enhanced durability under abnormal operation Our original self-radiation structure (Patented) efficiently disperses bearing friction heat to protect the pump under abnormal operating conditions. In addition, our noncontact structure prevents contact between rear thrust face and bearing, to eliminate heat buildup during dry running. Expanded versatility he SM-F has a modular structure to handle liquids with high specific gravities. Use of standard motors extends the range of liquid application. Easy maintenance he pump wet end can be removed from the motor as a complete assembly without dismantling, thanks to an additional rear casing support. he pump wet end comprises the minimum number of parts for easy maintenance. indle Rear thrust Bearing Heat-Dispersion hales Magnet capsule Impeller Rear casing support Rear casing Fast self-priming he SM-F requires no external self-priming chambers or valves. he gas-liquid separation design ensures fast selfpriming. An exceptional self-priming duration of up to 4m in only 9 seconds is now possible. Rear casing support he pump wet end is easily removed from the motor by removal of 4 mounting bolts on the motor bracket. he rear casing support performs easy maintenance and draining of any residual liquid at other place.

IWAKI SELF-PRIMING MAGNEIC DRIE PUMPS SM-F Principles of Self-Priming: 1 2 F A E D 3 C B 1 2 Prime the pump with liquid. On starting, the pump will suck both gas and liquid into its inlet. his mixture moves through front case A to the front casing, where it is agitated by the impeller. he mixture is discharged through pump chamber B to rear case C, where gas and liquid separation then occurs. Gas is bled from the discharge port D while some liquid is retained. Liquid in the rear case C is fed back through circulation hole E to the front casing, where it is again mixed with entrained gas by the impeller. his recirculation & bleeding process continues until gas from the suction side F is completely expelled. 3 Once all gas is expelled, normal centrifugal pump operation is resumed. Sufficient liquid remains in the casing for subsequent self-priming once the pump is stopped. 4

IWAKI SELF-PRIMING MAGNEIC DRIE PUMPS SM-F Precautions on the selection of pumps Self-priming considerations 1.he performance curves on this catalogue are based on the operation with 2ºC clean water in flooded suction. Keep a margin (3% of the curves) when selecting the pump. 2.he magnetic pump cannot run continuously with a closed-discharge. Be sure to observe the minimum flow rate. he minimum flow rate : 1L/min SM-F44 : 1L/min SM-F4 : 2L/min 3.Select a pump model according to liquid specific gravity. Keep a margin (% or more) for motor output. Pump shaft power x ecific gravity x 1. or more (margin) Motor output 1.he diameter of the piping on the suction side should be the same as that of the pumps inlet port (22 : 2mm, 44 : 4mm, 4 : mm), and the length of the piping should be limited to less than 4.7m. A larger pipe diameter or longer piping could adversely affect the self-priming performance, or could even hinder the self-priming process itself. 2.In cases where the liquid level fluctuates, take the height from the lowest liquid level as the maximum self-priming height. 3.Always perform priming before first operation, and start the pump only after the pump chamber has been filled with the handled liquid. 4.7m 4.m 4.he self-priming performance (4m in 9 seconds) is based on the operation with 2ºC clean water on the right piping condition. Self-priming performance varies with liquid temperature, characteristics and piping conditions. Obtain a rough guide of the highest possible self-priming height at each liquid specific gravity by the following formula. he highest possible self-priming height[m] = Self-priming height with clean[m] / Liquid specific gravity 4.o prevent early deterioration, avoid frequent start/stop of the pump..if a foot valve is installed on the suction pipe. pipe resistance may increase so that the pump cannot suck liquid enough. Dia. of suction pipe : 2mm SM-F44 : 4mm SM-F4 : mm Optional accessories Iwaki dry running protector DR series Model DR is electric current sensing type dry running protector. It detects the decreased load current (lower limit) to stop the pump when it runs dry or runs with air sucking in. It can detect over-load, too. Current figure to be set is indicated on LCD. Both top/bottom figures can be set. op:over-load Bottom:Dry running, air sucking-in operation, operation with suction side closed Built-in current transformer DIN rail mounting It is unable to use DR when inverter is employed in the system. ecification Model Motor power (/6Hz) Applied motor (/6Hz) Power control (/6Hz) Power Input Detective current Current transformar (C) Outer dimension DR-2 /6Hz DR-1, DR-2 2 to 24 three phase 38 to 44 three phase.4kw to.7kw.7kw to 1kW 1 to 24 single phase 1 ±1%single phase(dr-1), 2 to 24 ±1%single phase(dr-2) 3.W.A to 32.A Built-in D8 W13 H122 6-6 Kanda-Sudacho 2-chome Chiyoda-ku okyo 11-88 Japan EL : (81)3 324 293 FA : 3 322 8892 ( )Country codes IWAKI has global net work.
