4.2 Description
The S-VSI model range has threaded connections on the suction and discharge ports.
The VSI is an oil-free double shaft screw vacuum pump in which two parallel screws mesh with each other
without contact. The gas flows into the pump’s suction chamber and compressed by the rotary movement
of the screw rotors in the direction of the outlet. Due to our continuously variable pitch screw design, the
gas is drawn in and is gradually compressed to atmospheric pressure. The counter-rotating screw rotors are
synchronised by a set of gears. The synchronous gears and bearings are splash-lubricated with oil.
The gearbox and the compression chamber are separated from each other by special seals. The gearbox is
sealed from the outside with shaft seals and O rings, as well as the compression chamber with piston rings.
There is also an atmospherically vented area that can be pressurized with a sealing gas (special version).
The VSI is driven by a standard NEMA three-phase motor.

Set up and operation
4.3 Areas of application
The VSI pumps are suitable for the evacuation of closed volumes for a continuous vacuum within a pressure
range of: 0.075 to 760 Torr.
They are also suitable for handling humid gas streams due to its high water vapor tolerance.
The maximum pumping capacity is 224 cfm at 60 Hz. Data sheet D832-44-US shows the vacuum versus
capacity performance curve.
If the unit is switched on more frequently (at regular
intervals of > 8 times an hour) or at higher ambient
temperatures and intake temperatures, the excess
temperature limit of the motor winding and the
bearings may be exceeded. Please contact the
manufacturer should the unit be used under such
conditions.
If it is installed outdoors, the pump must be
protected from environmental influences, (e.g. by a
protective roof).

5 Installation
5.1 Preparing for installation
Check the following points:
 • Pumpisfreelyaccessiblefromallsides
 • Donotblockventilationgridsandholes
 • Sufcientroomforinstallingandremoving
pipes and for maintenance work, particularly for
installing and dismantling the pump
 • Noexternalvibrationeffects
 • Donotdrawinanyhotexhaustairfromother
pumps into the cooling system.
The oil fill ports (Fig. 2/H, H1), oil sight glass (Fig. 2/I, I1)andoildrains(Fig.2/K,K1), cooling water
inlet (Fig. 3/C) and cooling water outlet (Fig. 3/D) must be easily accessible.
The cooling air intake (Fig. 3/E) and cooling air outlets (Fig. 3/F) must be at least 1 ft. away from
adjacent walls. Hot cooling air coming out must not be allowed to recirculate.
5.2 Installation
NOTICE
The pump may only be operated in a horizontal
position.
Damage may result from the pump tipping
over and falling.
When installed at more than 3000 ft. above sea
level, a reduction in capacity occurs. Contact
Engineering for more information.
Contamination in the intake air
Protect the pump intake port with an external filter
canister unit.
Check for oil leakage
Risk of falling due to oil spills!
Ensure that the mounting surface complies with the
following conditions:
 • Levelandstraight
 • Themountingsurfacemustbedesignedto
accept the weight of the pump.
It is possible to install the pump on a firm surface without anchoring. When installing on a
substructure we recommend mounting with vibration isolators.

18 |www.elmorietschle.com © Gardner Denver Schopfheim GmbH, Gardner Denver Deutschland GmbH
Installation
5.3 Connecting pipes
a) Vacuum connection at (Fig. 2/A, 3/A).
NOTICE
Damage to the threaded inlet connection
may result from excessive torque during the
installation of the process piping. Use only the
sufficient amount of torque to obtain a sealed
connection.
Small diameter and excessive length of piping
may reduce the pumping capacity. Contact
Engineering for pipe size recommendations.
b) The discharged air can be blown out through the
exhaust silencer at (Fig. 3/B) or conducted away
using a hose or a pipe.
NOTICE
The air vent (Fig. 3/B) must not be closed or
restricted.
Back pressure on the discharge port is only
permissible up to:
S-VSI (44) 10 Hp < 2.9 psi
Prevent liquids accumulating in the vertical
exhaust line by installing a drip leg.

19

Installation
5.4 Connecting the cooling water pipe
NOTICE
Cooling water!
The vacuum pump must not be operated without
cooling water.
Potential pump failure
Ensure that the cooling water flow is not
interrupted.
a) Connect the cooling water pipe to the
cooling water inlet (Fig. 3/C) and the cooling
water discharge pipe to the cooling water
outlet (Fig. 3/D).
NOTICE
Only use pH-neutral, clean and filtered water
for cooling
Dirt particles and aggressive water may lead to
malfunctions or to premature wear in the cooling
system
Suitable cooling water
see Info “Recommended water quality”, Page 4
NOTICE
The cooling water operating pressure must not
exceed 87 psi.
Cooling water temperature must be between
60 – 122 °F.

20 |www.elmorietschle.com © Gardner Denver Schopfheim GmbH, Gardner Denver Deutschland GmbH
Installation
b) When connecting a circulating cooling system to
an external cooling system, it must be filled with
cooling fluid.
NOTICE
Rinse the pipe network on the process side
before connecting it
A filter element must be installed in the pipe
network to prevent foreign debris getting into the
heat exchanger.
Risk of frost damage in the cooling system
Freezing cooling water may lead to extensive
damage to the pump. Therefore mix the cooling
water with at least 10 % of anti-freeze. The
amount of anti-freeze used must be adjusted to
the ambient climatic conditions.
Handling anti-freeze
Anti-freeze may contain harmful ingredients, such
as ethylene glycol that could damage your health,
especially if swallowed.
5.5 Filling with lubricating oil
a) Fill the lubricating oil (for suitable sorts see
“Maintenance”) for the gears and bearings into
the oil fill ports (Fig. 2/H, 2/H1) up to the middle
of the inspection glasses (Fig. 2/I, 2/I1).
b) Close the oil fill ports.
