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 GPC is a machine-worked centrifugal pump in PP(Polypropylene) or PVDF(Teflon). Green pump gpc is a chemical worm centrifugal pump. The pumping principle is carried out with a stationary shaft, on which a closed scooter rotates. As in all magnet-coupled pumps, the pumped liquid circulates around the inner magnet. Magnet-coupled pumps do not tolerate dry running or operation against sealed valve (Q minimum problems) or that pump without a defined counterpressure (Q max. problem). We have relay solutions based on Cos. Phi and overcurrent, which can monitor magnetic-coupled pumps and disconnect them and/or alert in case of Q min./Q max. error.

Green Pump GPC was referred to as Caster MC and Caster MCA in the Caster era.

Use: Dangerous liquids such as acid, bases, distillate, sterile water, alcohols, petrol, fire and explosive liquids. Green Pump's GPC is available in capacity from approx. 1.5 m3/h to 100 m3/h. For particularly cold liquids down to -50 C (On request only!) we recommend that the magnet coupling NH3 be over-rented. T(max) up to 60C (PP) /120C (PVDF) (query only).
