DPL-Z version
Two pumps are arranged in a shared housing (twin-head pump). The pump housing has an
in-line design. All pump housings are provided with pump support feet.
Only the base-load pump is operated in control mode in connection with a control device.
The second pump is available to fulfil full load operation requirements as an auxiliary peak
load. The second pump can adopt the reserve function in the event of a fault.
NOTICE
Blind flanges (accessories) are available for all pump types/housing sizes
from this series. When replacing the motor impeller unit (motor with im-
peller and terminal box), a drive can therefore remain in operation.
NOTICE
To ensure the standby pump is ready for operation, operate the standby
pump every 24 h at least once a week.
Stagnation must be avoided in accordance with the local requirements and
regulations for drinking water application.
•
Installation/dismantling: The technician must be trained in the
use of the necessary tools and fixation materials.
•
Observe national and regional regulations!
•
Observe locally applicable accident prevention and safety regu-
lations of professional and trade associations.
•
Provide protective equipment and ensure that the protective
equipment is worn by personnel.
•
Observe all regulations for working with heavy loads.
DANGER
Danger of death due to lack of protective devices!
Due to missing protective devices of the terminal box or near the coup-
ling/motor, electric shock or contact with rotating parts can lead to life-
threatening injuries.
• Before commissioning, safety devices such as coupling covers that
were removed must be reinstalled!
DANGER
Danger of death from falling parts!
The pump itself and pump parts can have a very high net weight. Falling
parts pose a risk of cuts, crush injuries, bruises or impacts, which can be
fatal.
• Always use suitable lifting accessories and secure parts against falling.
• Never stand below a suspended load.
• During storage and transport, as well as before all installation and as-
sembly work, ensure that the pump is in a safe position and standing
securely.
