Best Practices for Installation of
VX Rotary Lobe Pumps
WELCOME TO VOGELSANG FACTORY TRAINING

If you are not installing your new pump
right away, there are steps you must
take to ensure the pump remains in
working condition when it comes time
for startup.
Vogelsang Service Webinar | Storage
Storage

1. Flush pump with clean water (or water glycol mix), empty and allow it to dry.
2. Lightly grease bare metal surfaces and shafts.
3. Store the pump assembly in horizontal position in a dry area.
4. Temperature must not go below 23°F and the relative humidity not less than 60%.
5. No direct exposure to sunlight or UV light.
6. No aggressive, corrosive substances (contaminated air, ozone, gases, solvents,
acids, alkalis, salts, radioactivity etc.) in the immediate vicinity.
7. No constant vibration or oscillation.

Short Term Storage

1. Flush pump with clean water (or water glycol mix), empty and allow it to dry.
2. Store the unit in a low humidity environment, allowing excess moisture to evaporate
3. Open the cover plate of pump and spray a long-term preservative (e.g. SHELL ENSIS)
on all bright pump internals and the inside of the cover plate.
4. Rotate the pump manually (at least two revolutions) to ensure complete and even
coating of the surfaces in contact every 30 days.
5. After rotation spray again all bright pump internals with the long-term preservative.
6. Close the pump cover plate.
7. Seal pump connectors carefully with metallic full face blind flanges and gaskets.
8. Spray the long-term preservative on all exposed metallic parts of the complete unit.
9. Fill the pump gear box nearly full with the proper gear oil. Consider thermal expansion.
10. Fill the drive gear box nearly full with the proper gear oil. Consider thermal expansion.

Long Term Storage

1. Remove long-term rust preservative.
2. Drain the gear oil of the pump gear box to the rated oil level according to the
O&M manual.
3. Drain the gear oil of the drive gear box to the rated oil level according to the
O&M manual.
4. Check the seals and gaskets properly; if any changes regarding shape, color,
hardness or sealing effect are detected, they must be replaced.

Recommissioning

Follow all best practices for safety when working on
Vogelsang Equipment.
Preparing for Installation

Lockout & Tagout
Important:
1. Follow all Lockout & Tagout procedure before
any work is performed on the pump.
2. This sticker (or one similar on older models)
came with your pump. Make sure your pump is
ready to be serviced by performing steps 1-7.
3. Be sure to depressurize the pump before any
work is performed.
Vogelsang Service Webinar | Safety

Over Pressurization
Risk of injury from bursting components and liquid
spraying out under high pressure.
• The maximum operating pressure must not be
exceeded at any time.
• Observe and implement the recommendations in
for installation in pipelines.
• Protect the pump assembly against excess
pressure. For example, the following safety
devices can be used:
• current limiter on the motor
• pressure relief valve
• cut-off with a pressure switch
• overload coupling

Run Dry
Even though our pumps are allowed to run dry from
time to time, a brand new pump may develop
friction during the break-in period. Friction could
lead to heat and should be avoided.
• Avoid pump dry running during startup. Prevent
the pump from running dry using, for example:
• temperature monitor
• level gauge
• flow rate gauge

Moving the Pump
Depending on the chosen configuration, assemblies
may be moved in a variety of ways.
• Always follow basic safety practices when
moving heavy equipment.
• All assemblies come with factory installed lifting
points and should not be removed or relocated.

Moving a Bare Shaft Q Pump
Simply lift a Q-Series pump by the
lifting ring located in the center.
Removing the Oil Bottle is a best
practice when moving the pump
but is not always necessary for
short moves.

Moving a Bare Shaft QD Pump
Larger QD-Series pumps will have
two lifting points. One is the same
as the Q-Series and the other will
be located on the outboard end of
the pump. The fitting at the
outboard end may be a ring or a
tab depending on pump model.
Removing the Oil Bottle is a best
practice when moving the pump
but is not always necessary for
short moves.

Moving an Inline Assembly
Moving a complete assembly will
require a bridle to be composed of
four cables or chains connected to
the four slots located in the
channel base.
Do not use the lifting rings to move
a completed assembly. They are
only rated to move the individual
component they are attached to.
Removing the Oil Bottle is a best
practice when moving the pump
but is not always necessary for
short moves.

Moving a Belt Drive Piggy Back Assembly
Moving a complete assembly will
require straps to be threaded
under the motor mounting plate.
Make sure your straps are rated
for the weight of the complete
assembly.
Do not use the lifting ring on top of
the motor! It is only rated to lift the
motor itself.

Installation

Mounting Flanges
Most pumps come complete with a
set of flanges. The flanges will be
mounted to the skid to prevent
damage during shipping.
All hardware will be included such
as hex bolts, washers and flange
gaskets.
Simply insert the gasket between
the pump and flange. Then thread
each bolt in and secure.
Vogelsang Service Webinar | Installation
All piping must be supported. The
flanges and pump are not designed to
support connected piping!

Optional Grouting
Our customers sometimes prefer
to bolt inline assemblies to the pad
and then apply grout above the
flange to secure the pump and
prevent any vibration.
Our pumps are pulsation-free
which means grouting is not a
requirement but is an acceptable
installation method.
It is recommended that only the
flanges at the bottom of the base
be grouted. This will ensure
accessibility to underside of the
base for maintenance purposes.

Coupling Alignment
Vogelsang offers two basic assemblies
for most applications. The belt drive
configuration must be aligned by
verifying that both sheaves are aligned
using a straight edge.
Inline assemblies use a three part
coupling device that must also be
aligned to avoid any vibration or
unnecessary wear.
Vogelsang Service Webinar | Alignment

Coupling Alignment for Inline Assemblies
The alignment of the
coupling must be
periodically checked. If
there is vibration during
operation, alignment is
sometimes the cause.
Alignment can be
verified by using a
straight edge or other
devices.
Vogelsang Service Webinar | Alignment

Surflex Coupling Alignment
Check parallel alignment by placing a
straight edge across the two flanges
and measuring the maximum offset at
various points around the periphery
without rotating the coupling.
