Intended use
The Vogelsang rotary lobe pump (hereinafter "pump" or "machine") is a self-priming positive displacement
pump for pumping fluids ranging from water-like to highly viscous (hereinafter "medium").
The medium can be chemically neutral, acidic or alkaline. It can be loaded with solid particles and/or gas.
The maximum free passage specified in
Chapter
"Specifications" must not be exceeded.
The pump is designed to pump the medium specified by the customer.
For a different medium, or if the pump was not designed for a specific application, the materials of the wetted
pump components must be checked for suitability. In some cases the pump must be reconfigured.
The pumps described in these operating instructions are not intended for use in potentially explosive
atmospheres.
Any other use is contrary to the intended use. Vogelsang is not liable for any damage resulting from such
incorrect use.

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
