1.2 Safety-related Information
SEEPEX machines are built in accordance with the state of the art. Neverthe-
less, there is a residual risk, because the machine works with:
• Mechanical movements that pose a danger
• Electrical voltages and currents
1.3 Designated use
SEEPEX machines are individually configured. The machine is allocated to the
operating and assembly instructions based on the commission no. The
commis-sion no. is indicated on the type plate of the machine and on the
cover sheet of the operating and assembly instructions.
Observe the following points to ensure compliance with the intended use:
Use the machine only for conveying media in accordance with the technical
data ( chapter 3)
Use the machine only within the performance data as specified in the tech-
nical data ( chapter 3)
Make alterations and modifications to the machine only after obtaining the
approval of SEEPEX
Use the machine only in commercial and industrial areas
Do not use the machine in explosive areas
1.4 Foreseeable misuse
Any use other than the intended use or any different use of the machine will be
considered as improper use and can cause serious physical injury and damage
to property.
In particular, the following is not admissable:
Conveyance of conveying products other than those specified in the techni-
cal data ( chapter 3)
Operating the machine outside of the performance data specified in the tech-
nical data ( chapter 3)
Operating the machine without safety and protection devices
Mechanical or electrical bypassing of machines or machine parts
Use of parts other than the original parts
Alterations, modification and manipulation
Non-compliance with instructions and prescribed operating, maintenance
and servicing conditions
Non-compliance with the rules and regulations in the country of use and the
statutory provisions and accident prevention regulations when handling the
machine
Operating the machine in explosive areas
1.5 Structure of warning notes
For the protection of personnel and for the safe and efficient use of the ma-
chine, observe warning notes.

Description of the pump
2.1 General description
seepex pumps are members of the group of rotating displacement pumps.
• Characteristic features
– Special configuration/arrangement of the rotor and stator pumping elements.
– Motion sequence
2.2 Mode of action and pumping principle of the seepex pump
• Sealing bands are produced through geometric design/contact of both conveying elements.
• Sealing bands ensure a perfect fit between the suction and pressure side.
Result:
– Increased pump suction.
– Higher pressure build-up independent of speed possible.
