Intended use
The Vogelsang rotary lobe pump (hereafter referred to as "pump" or "machine") is a self-priming positive
displacement pump for pumping fluids ranging from water-like to highly viscous (hereafter referred to as
"medium").
The medium may be chemically neutral, acidic or alkaline. It may be loaded with solid particles and/or gas.
The pump is designed to pump the medium specified by the customer.
For a different medium or if the pump is not designed for a particular application, it has to be checked
whether the characteristics of the pump are suitable for the pump medium in terms of the material and fluid
group. In some cases the pump or the pump connectors must be reconfigured.
In addition to these specifications, the specifications in
Chap.
"Specifications" must be complied with as
well.
Any other use is contrary to the intended purpose. Vogelsang is not liable for any damage resulting from
incorrect use.
Foreseeable misuse:
The machine is
NOT
intended for the following uses:
•
Potentially explosive atmospheres
•
Operation subject to cavitation
•
Use in the food industry without checking the specific hygiene requirements for the pump

General safety notes
WARNING
Risk of injury (catching, crushing, collision) due to rotating rotary lobes if the machine starts up
unexpectedly!
Before starting maintenance and repair work (opening covers, disassembling connectors) and before
troubleshooting, switch the machine off and secure it against being switched on again.
WARNING
Risk of injury from medium escaping under high pressure!
If the maximum differential pressure is exceeded, machine parts may burst and medium may spray out.
•
The maximum differential pressure must not be exceeded
Chap.
"Specifications".
•
Observe and implement the recommendations in
Chap.
"Installation in pipes".
•
Protect the machine or system against overpressure. For example, the following monitoring devices
can be used:
A current limiter on the motor
A pressure relief valve
Cut-off with a pressure control switch
An overload coupling
