2 Safety
DANGER!
Mortal danger in the event of non-compliance with the docu-
mentation!
– Observe all of the documentation relating to the pump and all
system components.
– Reading and observing the documentation is a prerequisite for
proper use of the product.
2.1 Intended use
n Use system exclusively for pumping the agreed pumped medium (
pump
data sheet).
n Adhere to operating limits (
pump data sheet).
n Avoid dry running:
– Ensure that the pump is only put into operation with pumped medium and
is not operated without pumped medium (
Ä
Chapter 6.1.7 ‘Filling and
bleeding’ on page 50).
n Avoid cavitation:
– Open the inlet side valve fully during pump operation and do not use for
regulating the pump capacity.
– Open the outlet side valve fully during pump operation.
n Never operate the pump against a closed or partially closed valve in the
outlet line.
n Avoid motor damage:
– Observe permissible number of motor switch-on instances per hour (
manufacturer's instructions).
n Only use the pump if it is in a technically optimal condition and ensure it is
operated in accordance with the regulations and in a safety and risk-aware
manner under observance of this manual.
n Any other use must be agreed with the ITT Bornemann GmbH.
n Observe the operational limits of the pump in relation to temperature, pres-
sure, viscosity, pump capacity and speed (
pump data sheet).
n When pumping liquids containing solids comply with the limit values for the
proportion of solids and grain size ( pump data sheet).
n When pumping liquids containing gas comply with the limit values for the pro-
portion of gas (
pump data sheet).
n Incorporate suitable safety valves (pressure safety valves are not system
safety valves).
n Do not use the pump without a pressure safety valve or similar safeguard
against exceeding the differential pressure.
n Do not use the pressure safety valve for regulating the pump capacity or
pressure.
n Do not operate the pump without a check valve.
n Connect the inlet and outlet lines correctly in accordance with the direction of
flow (see connection labelling).
n Check the installation direction of the check valve.
n Implement and check the connection labelling for the inlet and outlet lines.
2.2 Improper use
Any use other than uses detailed under
Ä
Chapter 2.1 ‘Intended use’ on page 10
shall be considered improper and is impermissible, for example:
