Green Pump GPTA Sanitary is designed for Food and Pharma applications where there is a need for magnetically coupled pumps.
The pump is internally polished to RA 0.6 and equipped with 3.1 certificates and FDa approved elastomers and carbon sliding bearing materials.

GREEN PUMPS formerly Caster Pumps produces magnetically coupled pumps in stainless steel and plastic. The magnetically coupled pump is shaft sealless and therefore emission-free. The pumps meet the requirements of the 1990 EPA Clean air directive. The magnetically coupled pump solution is a cost-effective way to get around complicated shaft sealing solutions, typically in connection with hazardous liquids.

Like all magnetic drive pumps, the pumped liquid circulates around the inner magnet. Magnetically coupled pumps cannot tolerate dry running or operation against a shut-off valve or pumping without a defined back pressure. We have relay solutions based on cos phi and overcurrent that can monitor magnetically coupled pumps and disconnect and/or alarm in case of faulty operation.

Application: Hazardous liquids such as acids, alkalis, alcohols, gasoline, fire and explosive liquids. Clean in Place (CIP) especially used as booster and circulation pumps in connection with CIP applications, GPA Sanitary is suitable for due to its ability to pump liquids with high gas content up to 20%. This means that the pump is particularly resistant to cavitation effects, which are often a reality in high-temperature CIP applications.
