Pumps liquid refrigerants with flanged standard motor.
The type GP refrigerant pump is used when the conditions do not prescribe hermetic pumps. They 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.
Since the Type GP refrigerant pump was introduced in the 1970s it convinces customers with the robust design and fast spare part supply worldwide. The GP still remains the first choice for refrigerant pumps with flanged motor.
