2.3 Intended use

• The pump (set) must only be operated within the operating limits described
in the other applicable documents.
• Only operate pump sets which are in perfect technical condition.
• Do not operate partially assembled pump sets.
• Only use the pump to handle the fluids described in the data sheet or
product
• literature of the pump model or variant.
• Never operate the pump without the fluid to be handled.
• Observe the limits for continuous duty specified in the data sheet or
product literature (Qmin and Qmax) (to prevent damage such as shaft
fracture, bearing failure, mechanical seal damage, etc).
• Observe the minimum flow rate and maximum flow rate indicated in the
data sheet or product literature (to prevent overheating, mechanical seal
damage, cavitation damage, bearing damage, etc).
• Do not throttle the flow rate on the suction side of the pump (to prevent
cavitation damage).
• Only operate pumps/pump sets which are in perfect technical condition.
• Consult the manufacturer about any use or mode of operation not
described in the data sheet or product literature.
• Observe the limits for continuous duty specified in the data sheet or
product literature (Qmin and Qmax) (to prevent damage such as shaft
fracture, bearing failure, mechanical seal damage, etc).
• When untreated waste water is handled, the duty points in continuous
operation lie within 0.7 to 1.2 × Qopt to minimise the risk of clogging/
hardening.
• Avoid duty points for continuous operation at very low speeds and small
flow rates (< 0.7 × Qopt).
• Consult the manufacturer about any use or mode of operation not
described in the data sheet or product literature.
