GREEN PUMPS former Caster pumps produce magnet-coupled stainless steel pumps and plastics. The magnet-coupled pump is axle-proof and thus emission-free. The pumps meet the requirements of the 1990 EPA Clean air directive. The magnet-coupled pumping solution is an inexpensive way to get around complicated shaft sealing solutions, typically in connection with hazardous liquids.
Green Pump GPM is a cast-injected centrifugal pump in PVC or PP (polypropylene). To increase potency, the casting material is added to glass fibers. The pump is available in Stainless steel under the name GPMA
Use: Dangerous liquids such as acid, bases, alcohols, petrol, fire and explosive liquids. Like all magnet-coupled pumps, the pumped liquid circulates around the inner magnet. Magnet-coupled pumps do not withstand dry running or operation against a blocked valve or that pump without a defined counterpressure. We have relay solutions based on cos phi and overcurrent, which can monitor magnet-coupled pumps and disconnect them and/or alert in case of malfunction.
