1 IWAKI CHEMICAL GEAR PUMPS

2 Highly Corrosion-Resistant Sealless Gear Pump Iwaki's Chemical Gear Pump is an internal gear pump made of highly corrosion-resistant materials. During pump operation, liquid does not come into contact with any of the pump's metallic parts. A magnet drive mechanism ensures that no liquid solution leaks from the pump. Thus, the safely handles most corrosive liquid chemicals, including acids and alkalis. Since the is pulsation-free and features precise discharge output, this pump is ideally suited to metering injection without pulsation. Sealless, highly corrosionresistant design All pump components in contact with the liquid are made of PVC, silicon carbide and fluorine resin, all of which are resistant to most acids and alkalis. The pump uses no seals, which eliminates the risk of leaks. High-durability ceramic gears The 's ceramic gears are highly resistant to abrasion, galling and seizure, ensuring reliable high-speed operation. Pulsation-free and precise discharge control The causes no pulsation of liquid in high-speed operation. Discharge is proportional to the pump s rpm speed, which can be precisely controlled by an inverter (frequency converter), thereby allowing liquid metering, transfer and other treatments. Low flow rate, high discharge head and self-priming The 's low flow rate and high head specification make it suitable for many chemical-injection processes. Self-priming up to meter in height is possible. Note : Self-priming height varies depending on the liquid s properties and temperature as well as the piping configuration. Please contact your distributor for details on self-priming applications. Lightweight and compact The 's pump is close coupled to its motor, eliminating the need for intermediate coupling and making the assembly both lightweight and compact. The s space-saving design makes it suitable for built-in pump systems. GM-2V Flange type

3 IWAKI CHEMICAL GEAR PUMPS Operating principle A pinion (drive gear) coupled with a shaft supported by two bearings meshes with an internal gear (driven gear) whose periphery is supported by a strong bearing. Liquid is transferred by a change in the capacity of this meshed portion. In the suction process, the gears are disengaged and a space defined by the two gears and the casing expands. The liquid is drawn into the space by the negative pressure generated. In the discharge process, their teeth begin to mesh and space defined by the two gears and the casing is reduced to force out the liquid. is useful in the following cases Low flow rate and high pressure applications with chemical solutions Automatic injection of coagulant at a constant mixing ratio. Pulsation-free metering, injection and transfer of chemical solutions Metering of paper-making dye and sodium hypochlorite. Easy control of process factors such as flow rate and pressure Low-cost, reliable control of rpm levels. No need for pulsation dampener or accumulator Simple piping without pulsation is possible. Bypass piping using a large-flow rate centrifugal pump No losses due to bypassing. Excellent corrosion resistance against acids and alkalis Unlike general-purpose gear pumps, the s metallic components never come into contact with liquids and are acid and alkali resistant. Designed to make diaphragms unnecessary pumps do not employ any seals or diaphragms. Self-priming Self-priming up to meter in height (when wet) is possible. 2 GM-2V Rc connection type (IEC Motor Model) 2

8 IWAKI CHEMICAL GEAR PUMPS Fine ceramic have led to exciting innovations. The Iwaki G series chemical pump is the first internal gear pump designed for chemical process applications, in which gears of fine ceramic (SiC and Silicon nitride) are used. Without detracting from any of the advantages of conventional internal gear pumps abrasion resistance, chemical resistance, lowviscosity characteristics and sealing characteristics have been remarkably improved. In addition to the gland packing/mechanical seal type (Model GX), magnetic drive sealless type (Model GM) are available as standard products for an expanded range of uses. The G series is an advanced gear pump, capable of dealing with a wide range of industrial processes which continue to increase in sophistication. GM type Specifications Max.discharge capacity :.2/42.
