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 modifications,
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 fluid 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 specifications.

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 specifications
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 confirmed 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 configurations on the part of the user not confirmed
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 fluids 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 flammable liquids.

2.3 Specific 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-
Identification
II 1/2 G IIB T4.
• Only use explosion proof drive motors.
