2 Chemically resistant self-priming magnetic drive pumps which can tolerate abnormal operation The SMX-F is a horizontal self-priming magnetic drive pump made from fluororesin. Our original self-radiation structure enhances resistance to dry running, cavitation, and closed-discharge operation. In addition, the use of standard motors extends the range of application. 3 SMX-F441 SMX-F221 1

3 SMX-F series Excellent corrosion resistance The casings, impeller assembly and magnet capsule are made of fluororesin(cfretfe). Other wet-end parts are made of highly corrosion resistant materials such as carbon, ceramic and the like. The pumps can handle almost type of chemicals including strong acid/alkali. Expanded versatility The SMX-F has a modular structure to handle liquids with high specific gravities. Use of standard motors extends the range of liquid application. Easy maintenance The pump wet end can be removed from the motor as a complete assembly without dismantling, thanks to an additional rear casing support. The pump wet end comprises the minimum number of parts for easy maintenance. 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. Spindle Rear thrust Bearing Heat-Dispersion hales Rear casing support Magnet capsule Impeller Rear casing Fast self-priming The SMX-F requires no external self-priming chambers or valves. The 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 The pump wet end is easily removed from the motor by removal of 4 mounting bolts on the motor bracket. The rear casing support performs easy maintenance and draining of any residual liquid at other place. Examples of application Pumping up from underground tank Underground tank at chemical plant. Underground tank or pit of waste plant. Pumping up and out from top of tank and tanker truck Transferring etching and plating chemical from chemical bath. Sucking up chemical from truck. Pumping up from top of tank. Transferring chemical from tank to tank Transferring from main tank to daily tank. Refilling chemical from drum to tank. 2

5 SMX-F series 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. This mixture moves through front case A to the front casing, where it is agitated by the impeller. The 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. This 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

8 Precautions on the selection of pumps Self-priming considerations 1.The 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.The magnetic pump cannot run continuously with a closed-discharge. Be sure to observe the minimum flow rate. The minimum flow rate SMX-F22 : 1L/min SMX-F44 : 1L/min : 2L/min 3.Select a pump model according to liquid specific gravity. Keep a margin (% or more) for motor output. Pump shaft power Sp x Specific gravity x 1. or more (margin) Motor output 1.The 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.The 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. The highest possible self-priming height[m] = Self-priming height with clean[m] / Liquid specific gravity 4.To 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 SMX-F22 : 2mm SMX-F44 : 4mm : 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. DR-2 Current figure to be set is indicated on LCD. Both top/bottom figures can be set. Top: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.
