Permitted nozzle loads and torques at the pump nozzles
Designing suction and discharge piping
The suction and discharge piping must be designed so that a minimum of forces affect the pump. Do not
exceed the force and torque values as shown in the following table. The values are valid for when the
pump is operating or when it is idle.
About the data in the table
The data in the following table has the following characteristics:
• The data complies with the Europump Recommendation for pumps according to ISO 5199.
• The data is only valid for static piping loads.
• The values are valid for pump units with standard IC base frames (ungrouted).
• All of the values refer to standard materials EN-GJS400-18LT and 1.4408.
Permitted nozzle loads and torques at the pump nozzles
These nozzle loads and torques follow the Europump recommendations for this pump according to ISO
5199.
Table notes:
• The data for forces and torques are only valid for static piping loads.
• The values in these tables are valid for pump units with standard IC-base frames (not grouted).
• All values for forces and torques refer to standard materials EN-GJS400-18LT and 1.4408.
