Note: If you are in any doubt about the size of the pump required or if the conditions are unusual we will be glad to advise you if you give us the answers to the following questions:
1. Nature of liquid to be pumped. 2. Temperature of liquid to be pumped. 3. Quantity to be pumped (kg/h or litres/h). 4. Initial lift horizontal distance and net effective lift (i.e. initial lift less subsequent fall in discharge line).
5. Operating medium (saturated steam, superheated steam, compressed air or gas). 6. Operating pressure available. 7. The pump is generally used to drain water from a vented receiver but under certain circumstances can drain a unit from under steam pressure or vacuum - state which.
Note: To achieve rated capacity, the pump must be installed with check valves as supplied by Spirax Sarco. Use of a substitute check valve may affect the performance of the pump.
