Series GP can deliver up to 28m³/h or to 85m height. The GP is suitable for a large number of refrigerants and it comes with a service-friendly design using standard couplings. The standard coupling enables use of easy available regional standard flanged motors.
With its double shaft seal together with an oil barrier and a large oil-refill reservoir as well as a sight glass to check the oil level, it meets highest safety requirements, such as EN378. The double shaft seal is long-lasting when installed properly and is easy to replace.
The GP still remains the first choice for refrigerant pumps with flanged motor.
