▪
Only use the pump to handle the fluids described in the data sheet or product
literature of the pump model.
▪
Never operate the system without the fluid to be handled.
▪
Observe the limits for continuous operation specified in the data sheet or
product literature (Q
min
3)
and Q
max
4)
) (prevention of damage such as shaft
fracture, bearing failure, damaged mechanical seal, etc).
▪
When handling untreated waste water the duty points in continuous operation
lie within 0.7 to 1.2 x Q
opt
5)
to minimise the risk of clogging/hardening.
▪
Avoid duty points for continuous operation at very low speeds and small flow
rates (<0.7 x Q
opt
5)
).
▪
Observe the information on the maximum flow rates provided in the data sheet
or technical product literature (prevention of overheating damage, cavitation
damage, bearing damage, etc).
▪
Do not throttle the flow rate on the suction side of the system (prevention of
cavitation damage).
▪
For any operating modes which are not specified in the data sheet or product
literature, contact the manufacturer.
▪
Only use impeller types designed for the fluid handled, as described below.
Impeller with cutter
(impeller type S)
Suitable for the following fluids:
Faeces, domestic sewage and waste water
containing long fibres
Free-flow impeller
(impeller type F)
Suitable for the following fluids:
Fluids containing solids and stringy
material as well as fluids with entrapped
air or gas
Open, diagonal single
vane impeller
(impeller type D)
Suitable for the following fluids:
Waste water with solid substances and
long fibres
Prevention of foreseeable misuse
▪
Observe the minimum flow velocities for fully open swing check valves to prevent
the reduction of pressure and risk of clogging.
(Contact the manufacturer for the required minimum flow velocities/loss
coefficients.)
▪
Never exceed the permissible application limits specified in the data sheet and in
the product literature regarding pressure, temperature, etc.
▪
Observe all safety notes and instructions in this manual.
