Intended Use
The machine is intended for commercial use and may only be employed for delivery of the agreed
pumping media in accordance with this Operating Manual.
The operating points (delivery volume, pressure, rotational speed) mentioned in the pump specification
(
→
data sheet) should be understood as limit values and must not be exceeded.
Any change of the pump delivery conditions (e.g. delivery rate, delivery route, pressurisation level, pipe
diameter, throttle devices) may result in strongly changed operating conditions. If this occurs, compare
the new operating conditions with the data contained in the data sheet. You will need to consult with the
manufacturer if the changed conditions should exceed the data contained in the data sheet.
Deployment in the Ex area is prohibited unless not expressly intended for this purpose.
1.6
Predictable Misuse
•
Only use the pump to deliver the specified medium.
•
Do not operate the pump beyond the specified speed range.
•
The solids contents in the pumping medium must not exceed
the specified limit values for grain size and proportion of solids.
•
Take appropriate measures to ensure that no foreign objects (metal parts,
stones, etc.) can get into the pump and possibly cause damage.
•
Do not use the stationary pump as shut-off device.
1.7
Operating Restrictions
The screw pump is a positive displacement pump that can build up very high pressure. The
developing pressure with the delivery line shut can reach the multiple of the permissible system
pressure. This may result in serious damage to system components posing a risk to persons.
Possible damage to property
•
Do not operate against closed shut-off devices!
Breakage and risk of injuries!
•
Secure the pump through approved safety devices (overpressure protection).
•
Keep the relevant safety and handling instructions when delivering dangerous media.
•
Medium contamination through foreign objects may result in damage to the pump elements.
•
Observe the relevant legal requirements and the possibly resulting requirements and restrictions
when delivering and storing hazardous substances and inflammable liquids.
