The Vogelsang rotary lobe pump (hereinafter “pump”) is a self-priming positive displacement pump for
pumping aqueous to highly viscous fluids (hereinafter “medium”).
The medium can be chemically neutral, acidic or alkaline. It can be loaded with solid particles and/or gas.
The pump is designed for the medium to be pumped in accordance with customer specifications.
For a different medium or when the pump is not designed for a particular application, it has to be checked
whether the materials of the pump which come into contact with the medium are suitable. In some cases the
pump must be reconfigured.
Any other use is contrary to the intended purpose. Vogelsang is not liable for any damage resulting from
incorrect use.
The pump without connections or without drive is an incomplete machine. The pump installation instructions
are provided in the "Installation" chapter.
The declaration of installation is part of these operating instructions.
The pumps described in these operating instructions are not intended for use in potentially explosive
atmospheres.

Risk of injury from bursting components and medium spraying out under high pressure
•The maximum operating pressure must not be exceeded Chap. “Technical data" .
•Observe and implement the recommendations in the Chap. “Installation in pipelines".
•Protect the pump assembly against excess pressure. For example, the following safety devices can
be used:
a current limiter on the motor
a pressure relief valve
cut-off with a pressure switch
an overload coupling

Skin and eye irritation caused by auxiliary materials, operating materials and medium
•Protective clothing (protective goggles, protective gloves) must be worn during all work involving
possible contact with auxiliary materials, operating materials and medium. In certain situations these
materials or the medium can enter the buffer chamber or gearbox.
•Before opening covers, connectors etc., the pump assembly must be depressurised to prevent the
medium from spraying out.
•To protect against fluids spraying out, carefully and slowly open the buffer chamber and the gearbox.
Cover the valves or screws to be removed with a cloth or similar item where appropriate.

Risk of injury when loading and transporting the pump or the pump unit
•Use the lifting eye bolts on the pumps only for lifting the pump without mounted parts (for example,
the motor).
•The unit may only be transported suspended or screwed to a Euro pallet. Fig. “Transport aids”.
•During loading operations and when setting down the pump or the pump unit, it may be begin to swing
or fall. Risk of crushing! Therefore:
The loading and transporting may only be carried out by specially trained persons.
Standing under raised loads is prohibited. Direct persons out of the danger area.

Attention! In the case of new pumps that are not
placed immediately into operation, the shaft needs
to be rotated approximately every two months (at
least one revolution) to prevent the sealing surfaces
on the rotating rings from adhering to one another.

difficulties, it is possible to draw in through the discharge side. A reversal of the pumping direction is not
possible if the pipelines are protected by automatic check valves/return valves.

Risk of injury when loading and transporting the pump or the pump unit
•Use the lifting eye bolts on the pumps only for lifting the pump without mounted parts (for example,
the motor).
•The unit may only be transported suspended or screwed to a Euro pallet. Fig. “Transport aids”.
•During loading operations and when setting down the pump or the pump unit, it may be begin to swing
or fall. Risk of crushing! Therefore:
The loading and transporting may only be carried out by specially trained persons.
Standing under raised loads is prohibited. Direct persons out of the danger area.

Noise and vibration hazard
Wear
Noise, vibrations and oscillations can cause impairment of communication and discomfort.
To avoid wear, vibration and generation of noise:
•The base for the pump and motor must not be distorted during installation.
•The alignment of the coupling The alignment of the coupling must be checked and, if
necessary, corrected before start-up, Fig. “Alignment methods”.

5.3.1 Pump installation
•The pump may be installed in the standing, horizontal, vertical or suspended position. Fig.
“Installation versions".
With a horizontal installation, the inlet should be on the bottom and the outlet on the top.
In the case of a vertical installation, please request our “Technical Information
TINF.PU.019.xx", in which the filling and emptying of the gearbox and the buffer chamber are
described.
If the pump is to be suspended, please contact us .
•When installing the pump, ensure that there is easy access for maintenance work. If the hex head
screw plugs for draining the gearbox oil and buffer or quenching fluid are not easy to reach, drain
hoses may be used (part-no. PBT.013 and/or PBT.014).
•Ensure that the pump is free of constraints upon installation and also during operating.

5.3.2 Pipelines and connections
•Only use the pipeline diameters, wall thicknesses and materials recommended by us or by our
representatives. The sealing material must be compatible with the medium.
•Position the pressure and suction connections pointing upwards. This will ensure that the fluid remains
in the pump after it is switched off.
•Keep the pipeline as free as possible from foreign objects (stones, wood residues, etc.) in order to
prevent wear on rotary lobe and housing.

Danger of breakage! Note on installation of connections
Flange connections can exert excessive forces on the unit. Risk of breakage. The connectors must therefore
be mounted free of stress, i.e. the connectors must be mounted exactly one in front of the other before they

To protect from high pressure losses and cavitation, heed the advice for laying the
suction lines
•The maximum suction height is 8 m. This is the maximum distance between the lowest and highest
points of the suction pipe. Observe NPSH.
•Suction lines whose diameter is too small may restrict the suction capability of the pump. Caution
cavitation hazard!
If the diameter of the suction pipe is too small, the maximum suction height will be reduced by
the loss of pressure due to pipe friction. Contact us for a calculation .
•Suction lines over 30 m must be laid with a slope of at least 2 x pipe diameter in the direction of flow,
ensuring that the pipeline can never run dry Fig. “Long suction lines".
