- all clean and slightly
contaminated liquids
- aerated or fast steaming liquids
- boiler feed water up to 220°C
These pump types are specially applied in the areas:
chemical and petrochemical industry, installation engineering and process engineering
as well as installations of distillate tanks and beverage industry.
For codensates resp. boiler water up to 120°C pumps in standard design are suitable;
pumps in cooling- design (K) are applicable for handling liquids up to 220°C.
Using only one shaft seal on the Ndischarge side permits pumping
liquids in a high vacuum range, because there is no penetration of air on the suction side.
For handling liquefied gas a special design of this pump is available.
Important application fields:
- chemical and petrochemical industry
- boiler feed installations
- refrigerating installations
- process engineering
- tank installations
- booster installations
Please note that SRZS pumps are also available with magnetic drive.
