Main material CFRETFE IWAKI SELF-PRIMING MAGNETIC DRIVE PUMPS PATENT JAPAN / U.S.A. / EU / CHINA / TAIWAN
Chemically resistant self-priming magnetic drive pumps which can tolerate abnormal operation The 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. 43 441 221 1
IWAKI SELF-PRIMING MAGNETIC DRIVE PUMPS 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. 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 The 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. Spindle Rear thrust Bearing Heat-Dispersion hales Magnet capsule Impeller Rear casing support Rear casing Fast self-priming The 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

IWAKI SELF-PRIMING MAGNETIC DRIVE PUMPS 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

IWAKI SELF-PRIMING MAGNETIC DRIVE PUMPS 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 22 : L/min 44 : L/min 4 : 2L/min 3.Select a pump model according to liquid specific gravity. Aiways keep % allowance to motor output. Pump shaft power Sp x Specific gravity x 1.1 (margin) Motor output 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 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.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. 4.7m 4.m Dia. of suction pipe 22 : 2mm 44 : 4mm 4 : mm Optional accessories Iwaki pump protector DRN series Detects unusual pump operating conditions including dry-running and overload The DRN model protects equipment (including pumps) from damage!
