Transport and intermediate storage VW61.21.028 Fig. 5 Storage NOTICE Corrosion is possible due to storage in humid conditions with fluctuating temperatures! Condensation can corrode windings and metal parts. Store the pump/unit in a dry environment at a temperature which is as constant as possible. NOTICE There is a risk of damage to the winding and entry of foreign matter due to open ports!
Transport and intermediate storage Returns – Drain the pump completely. – Clean the pump and rinse it with clear water, especially with hazardous or risky pumped fluids. – Complete the declaration of clearance and return it with the pump. 20 EN 04/2019...
Installation Installation Installation site 5.1.1 Installation surface The installation surface must be level and horizontal in order to avoid damage. Observe weight indications! 5.1.2 There must be ground drainage Calculate the size of the ground drain according to the ...
Installation Pipes 5.2.1 Pipe sizing Suction lines which are too long have significant disadvantages: • Higher resistance which results in reduced suction performance and a higher risk of cavitation. A minimum length of double the inner diameter of the suction flange must be planned for the calming section in front of the suction flange.
Installation Installation The pump should be installed below the water level (max. 3 m) in intake mode. VW61.21.022 Fig. 6 BADU Block Multi Normblock Multi The BADU Block Multi filter housing must be set up completely on the foundation. The Normblock Multi must be set up so that the pump housing stands freely and is not supported.
Installation NOTICE The pump can be damaged by unauthorised mechanical strains being placed on the pump! Take the pipe up directly before the pump and connect it free of tension. Connect the pipe free of tension according to the VDMA standard sheet 24277.
Installation Adjust minimum diameter of the electrical pipes to accommodate the motor output and pipe length. If hazardous situations can occur, provide an emergency off switch according to DIN EN 809. The builder/operator must make a decision according to this standard. The use of a frequency converter or a smooth start is ...
Commissioning/Decommissioning Commissioning/Decommissioning Commissioning NOTICE The pump/unit can be damaged if it runs dry! Ensure that the pump/unit is always full of water. This also applies to checking the rotation direction. 6.1.1 Pre-requisites for commissioning • Electrical connection is available. •...
Commissioning/Decommissioning 6.1.3 Checking how easily the pump rotates After longer idle periods, the pump must be checked for how easily it rotates while it is switched off and free of tension. Turn the pump shaft in the drive lantern by hand. ...
Commissioning/Decommissioning Risk of frost: Drain the pump and pipes. Store the pump and pipes at risk of freezing in a dry place with no risk of frost. Decommissioning For pre-requisites for shutting down the pump "Switching the pump off" on page 27 NOTICE For idle periods exceeding one year, elastomer components must be renewed.
Faults Faults NOTICE It is normal for a few drops of water to escape from the mechanical seal from time to time. This is especially true during the break-in period. Depending on the water quality and number of operating hours, the mechanical seal can begin to leak.
