General Instructions
Description of the Vogelsang Positive Displacement Rotary Lobe Pump and how
it functions
The Vogelsang positive displacement rotary lobe pump employs right and left set lobes, top
and bottom, rotating in opposite directions, driven by an external power source, to move fluid
from the suction side of the pump to the discharge side.
During operation the lobes mesh together, forming cavities between the rotors and the casing.
The lobes mesh tightly together in the center of the pump and have a very small clearance at
the radial housing. As the lobes continue to turn, the fluid and objects are moved along the
outer perimeter of the pump. As the pump completes a full cycle, the fluid is pumped through
to the discharge side of the pump. The direction of flow is determined by the rotation of the
lobes. Vogelsang positive displacement rotary lobe pumps can operate in both forward and
reverse directions of flow.
If you are in doubt about the functionality of your Vogelsang product, please ask us. Any other
use is contrary to the intended purpose. The manufacturer is not liable for damages or wear
caused by incorrect use.

Pressure relief system, valves, etc, must be in
good working order and set to the appropriate
relief pressure. XXX
Under no circumstances should the pump or
its flanges, be used to support external loads.
All piping must be supported. XXX
Pump should be filled with liquid before initial
startup and any restart. XX
Liquid should be drained from the wet-end of
the pump, to insure it does not freeze, or
set-up in the wet-end. X
Insure the surrounding piping matches or
exceeds the port size of the pump, to reduce
the chance of cavitation. XXX
Confirm the NPSHA in the system is suitable
for the NPSHA of the pump, to ensure smooth
operation of the pump, without cavitation XXX
Insure suction and discharge gauges are
properly installed, and working. XXX
Insure all PM has been completed on the pump
and drive system. XX

Installation, Maintenance, Calibration & Repair
Installation
Vogelsang does not install equipment supplied as this is the responsibility of the contractor. See
section 2.A.1 for installation advice. However, when designing your system, keep in mind the below
guidelines.
When designing the pumping system:
DO - Confirm with the supplier the Net Positive Suction Head (NPSH) requirements for the pump, as
this is crucial for ensuring the smooth operation and preventing cavitation.
DO - Avoid suction lifts and manifold/common suction lines for two pumps running in parallel, as this
may cause vibration or cavitation.
DO - Protect the pump against blockage from incompressible solid objects e.g. nuts, bolts etc. Also
protect the pump from accidental operation against a closed valve by using one or all of the
following methods: relief valves, pressure switch, current monitoring device.
DO - Fit suction and discharge pressure gauges to monitor pressures for diagnostic purposes.
Depending on your requirements, the pump and drive (if supplied) may arrive mounted on a
baseplate. Our standard baseplates have pre-drilled mounting holes to accept base retaining
bolts. All mounting holes are required for best results against vibration and noise.
To provide a permanent, rigid support for securing the pump unit, a foundation is required. This
will also absorb vibration, and reduce strain on the pumping unit.
DO - Set appropriate pressure to the pump’s buffer chamber using the pressurized oil bottle that has
been installed on your pump.
DO - Check alignments. Pump may become misaligned during shipping. For direct drive assemblies,
make sure pump and motor are aligned and the coupling is making a straight connection. The
coupling guard must be in place at all times during operation. For piggy-back belt driven
assemblies, confirm that the sheaves are properly aligned and the belt is tensioned correctly.
The belt guard must be in place at all times during operation.
DO - Make sure that all equipment and piping are properly supported. The pump assembly and
flanges are only designed to support their own weight.

Equipment Alignment – Base plate
The base frame of motor driven units must not be out of alignment or under stress by the
mounting bolts to prevent noise and wear of coupling. After mounting, the alignment of
coupling must be checked and corrected prior to operation.
Retighten all motor and pump mounting screws on the frame after 20 initial operating hours.
For pumps with belt drive check the belt tension as described earlier:
• After the first 10 operating hours
• Then every 2000 operating hours
Use the eye bolts on the pumps only for lifting the pump without any additional
mounting parts such as the motor.

Trade Levels for installation
Consult with General Contractor as Vogelsang does not install equipment.
Special Rigging
Pump/Motor assemblies may exceed 3090 lbs. and so require some lifting device with chain
and hooks to engage lifting eyes on pump and motor. Assemblies should never be lifted by
pump alone, or by motor alone.
Special Test Equipment
No special test equipment is required for the installation of the pump assembly.

Safety
Identify all safety and tag-out procedures
Before setting into operation read and observe the contents of the operating
instructions and the safety advisories.
Warning and information stickers provide important information for safe operation. They may
not be removed. Observation of these stickers provides for your safety.
Before start up of operations you should familiarise yourself with all facilities and operating
options. Pump may only be set in operation if the suction and pressure pipes are connected so
that access to the pumping chamber is not possible. Before pump is set in operation, ensure
that access to the rotating parts (the drive shaft) is not possible.
The drive shaft must be completely covered by a coupling guard.
Before setting into operation, ensure that the discharge pipe is not completely closed off.
Otherwise the pump shaft seals or even the pump housing or the pipelines may be damaged
or destroyed by the resulting high pressure.
Before starting maintenance and repair work, turn off the drive and ensure that the pump
cannot be switched on by mistake.
Use the eye bolts on the pumps only for lifting the pump without mounted parts
(for example motor)!

Data from Startup & Testing Procedures
Actual certified field service reports will be inserted here, when conducted, and upon the final
printing of this manual.
Test method, equipment, and procedure
Pump start-up is dependent on actual application. On start-up flow rates, pressures and
speeds should be noted on the Start-Up checklist for comparison with design specifications.
Differences should be noted.
Flow meters, pressure gauges and similar instruments may be used or installed in the system
for observation of application conditions. Any request for technical assistance from Vogelsang
will require this data.
Certified Factory tests will be conducted on all products per the specification, and approved by
the engineer, prior to shipment.
Field tests will be conducted by the contractor per the specification. Vogelsang will witness
these tests.
