Safety devices
• Provide the following safety devices and ensure
their function:
- With possible electrostatic charge: provide the
corresponding earthing.
Statutory warranty
• During the guarantee period, obtain the
manufacturer‘s permission for modications,
maintenance work or alteration.
• Use only original components or components
authorized by the manufacturer.
Duties of the personnel
• Observe the notices on the pump and maintain
them in a legible state, e.g.rotation arrow, marking
for uid connections.
• Use protective equipment where necessary.
• Do not reach into the intake port of the pump.
• Only perform work on the pump during downtime.
• Ensure that the motor is disconnected before you
carry out assembly and maintenance work.
• After completing all the work on the pump, remount
the safety devices in accordance with specications.
2.2 Proper use
• The pump may only be installed in an upright position.
• The pump may only be used to pump the agreed
liquids (→ contract data sheet, → table of materials
table 7).
• Dry running must be avoided.
- Ensure that the pump is commissioned only with
liquid and is never operated without pump medium.
• Pumps delivered without a motor require completion
to a pump unit in accordance with the specications
of the machinery directive 2006/42/EC.
If the product and supplied accessories are used for
other purposes than the intended purpose, it is the
responsibility of the user to check the suitability and
admissibility. Product use not conrmed in writing by
the manufacturer absolves the manufacturer of any
liability.
The manufacturer is not liable for consequences of
incorrect treatment, use, maintenance, servicing and
operation of the appliance, as well as normal wear and
tear. The same applies if faults arise from intervention
or congurations on the part of the user not conrmed
by the manufacturer.
Prevention of obvious misapplication
(examples)
• Observe and comply with the operating limits of the
pump in terms of temperature, pressure, delivery
rate and speed (→ Appendix, table 8; contract
data).
• The power consumption of the pump increases
with increasing density or viscosity of the liquid.
To prevent an overload of the pump, coupling and
motor, comply with the permissible density and
viscosity (→ Appendix, table 9, table 10). A lower
density and viscosity is allowed.
• When pumping uids containing solids, maintain
the limit values for solid contents and grain size
(→ Contract data sheet, technical description).
• Do not use the pump tube to lift objects.
• For pump tubes from PP, PVDF and Alu following
applies:
- Do not operate in explosion hazard area.
- Do not use for pumping ammable liquids.
2.3 Specic danger
Explosion hazard area
→ Chapter 10: Instructions for the explosion protection
• Only use pump tubes made of stainless steel
(SS 1.4571) and Hastelloy C (HC) with ATEX-
Identication II 1/2 G IIB T4.
• Only use explosion proof drive motors.
