GM-V – Series
Highly corrosion-resistant sealless gear pump
IWAKI’s Chemical Gear Pump GM-V is an internal gear pump made of highly corrosion-resistiant 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 GM-V safely handles even the most corrosive liquid chemicals, including acids and alkalis. Since the GM-V is pulsation-free and features precise discharge output, this pump is ideally suited to metering injection without pulsation.
Highly Corrosion-Resistant Design
Liquid wet ends 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.
Lightweight and compact
Close coupled to its motor, eliminating the need for intermediate coupling and making the assembly both lightweight and compact. Space-saving design makes it suitable for built-in pump systems.
Quiet Liquid Transfer with Less Pulsation
Without the pulsation that is common to the reciprocating pump and the gear pump for general uses, liquid is transferred quietly and smoothly , not agitating or generating foam/bubbles.
Seal-Less Design
Magnetic drive seal-less pumps are free from leakage problems and the need for seal replacement.
Simple Device Configuration Easy Maintenance
By simply combining a PFC controller, magnetic flowmeter, inverter, and back pressure valve, it is possible to inject a constant flow with less pulsation even if there are fluctuations in the level of the suction tank or load fluctuations on the discharge side.
Constant Flow Injection with Excellent Controllability
Regardless of the temperature change, viscous liquid can be handled at accurate flow rate, which cannot do with other pumps. As the output is linearly related to rpm, the flow rate is easily controlled by changing motor speed. The pump achieves fixed injection with the rangeability 10 times greater than conventional metering pumps.
• Rangeability 1:100
• To perform constant flow Injection, use this pump with a PFC controller, magnetic flowmeter, inverter and back pressure valve.
Examples of applications
- Automatic injection of coagulant at a constant mixing ratio of coagulant in low flow/high head chemical lines.
- Quantitative transfer of paper-making dye.
- Transfer of sodium hypochlorite.
- Pulsation-free metering, injection and transfer of chemical solutions.
- Transfer of various acids, alkalis and chemical solutions.
