Attention: The pump should be put at safe places with proper ventilation, solid and flat base, and
clean floor, without corrosive gas. Otherwise, the pump will be damaged and the life of use will be
shortened.
Attention: In cold area, the coolant jacket must be drained after car stopped. Otherwise the
coolant may freeze and thus damage the pump shell.
2. Survey
2.1 Introduction
Roots pump have Vortex series and Vortex B series. As the input pressure is between 6.5-65 Pa,
the pumping speed is no less than 250m3/h, 500m3/h, 1000m3/h, 2000m3/h, 5000m3/h,
6000m3/h and 9000m3/h. It is a kind of roots vacuum pump in which a couple of lobed rotors turn
like 8- shape in high speed synchronously. Two rotors rotate
and produce aspiration and exhaust which principle is just like a
roots blower. As it works in a lower pressure, the free flow
distance of gas molecule is longer and the resistance of gas
passing a small gap is much large. Thus, a bigger compression
ratio can be gained so that it can also be used as a blower
pump. But it cannot discharge the gas to atmosphere directly
and requires to be used with a vacuum pump in series
connection.
Then the sucked gas is discharged to atmosphere through the
vacuum pump (as Diagram 1).
2.2 Features
(1) There are definite gaps between rotor and pump’s cavity, rotor and rotor which are not in
contact. As a result:
a. No friction, lower power consumption that is compared with an oil sealed mechanical vacuum
pump of the same pumping speed.
b. No Oil-sealing and lubrication so as to avoid being polluted to the vacuum pump by oil steam.
c. It is ok for pumping the gas with a little dust.
Diagram 1

6
www.bluelinevacuum.com
(2) As the rotor has a good geometric Symmetry, its rotational speed is higher than a common oil-
sealing mechanical vacuum pump and at the same pumping speed it has features of smaller
volume and lighter weight.
(3) When the pump is in operation, there is less vibration and its volume operating ratio is
about kv≈ 0.5.
(4) There is no compression in the pump similar than that produced in a mechanical vacuum
pump. So no discharge valve is required but agglutinative steam can be removed.
(5) The pump can be started quickly and a limit vacuum can be reached in a short time.
Except the above features, Vortex B series Roots Pump has it’s own relief valve which functions
to control roots pump's differential pressure between air-inlet and air-outlet. When the
differential pressure is over standard one the relief valve opens automatically. Because the
pump's inlet-outlet is interlinked, some of gas returns to the inlet. At this time, the pump operates
in a constant differential pressure. When the differential pressure is lower than that of a relief
valve, the valve close automatically (shown as Diagram2)
Diagram 2
2.3 Usage and model explanation:
Usage: vacuum degassing, vacuum smelting, vacuum heat treating etc, in metallurgical industry
and can also be used in chemical industry. Foodstuff, medicine, Electrical manufacture etc.
Especially when a water-ring vacuum pump is used for its pump, it can extract the gas with large
steam. So it is much suitable for productive procedures of distillation, evaporation, freezing and
drying etc.

4. Operating principle
The pump’s operating principle is shown as Diagram 3.When the pump is rotating, the gas in an
exhausted container directly enters the space encircled by two rotor and pump cavity and the gas
entered before is merely encircled by space Vo(see the shaded parts in Diagram). The mixed gas in
Vo is merely encircled, but not be compressed and expanded. With the rotation of a rotor, the
rotor’s top reaches the outlet port edge, the gas in pump’s outlet port will spread to the space Vo,
the mixed gas in Vo will be carried to a pump to be exhausted. Thus, with the rotor’s continuous
operation, more gas will be carried to outlet port and exhausted by the pump. That is the
functional principle of the pump’s volume.
When this pump is operating under a very low pressure, because of rotor’s high speed (3000rpm),
the linear speed of the rotor’ surface is near to molecular heat pace. At this time, the gas impacted
on the rotor is brought to an outlet port with a higher pressure and removed by beforehand
vacuum pump. That is the molecular functional principle of thin pump.
The combined action by the two principles makes this pump have features of a big pumping rate
and a stable pumping rate curve in an interval of 1.3x103～1.3 Pa.
According to this pump’s characteristics and different operating condition, different fore pump can
be freely chosen which is not required too high vacuum, but required to remove corrosive gas with
large steam or little dust. Completed with a double-stage water-ring vacuum pump and a piston
vacuum pump, the limit vacuum is lower and its power proportioning is different, too. Our
company can specially design various pump’s unit according to user’s different requirements and
operating conditions .Welcome to contact us by call or email.

5. Installation
1. Before installation, checking each parts and make sure there have no damaged, and to see
whether the product is fit to order contract.
2. The pump must be installed in a place of cleaning, no dust or a little dust and infection with
dielectrics. According to its operating condition, the pump’s inlet port can be equipped an anti-
dust device (such as an oil-sealed mechanical pump used as pump).
3. The pump’s operating environment temp. is 5-40 ℃and the max. Temperature rise is cannot
exceed 100 ℃.
4. According to operating condition, the pump can be installed to a cement base or steel frame
base which should be calibrated. Otherwise, it will be seriously affect the pump’s normal
operation.
5. The gas inlet pipe should be kept sealing, even a small leakage will affect its vacuum.
6. The length of a pipe is as short as possible, using less joint and elbow with its diameter less than
its pump’s bore.
7. A flexible soft pipe such as a metal bellows should be linked between this pump and a fore
pump so as to prevent damaging this pump because of fore pump’s vibration.
8. It is better to equipped a vacuum valve on the pump’s inlet and outlet pipes so as to keep the
vacuum of pump cavity after stopping operation.
9. A valve should be installed on inlet pipe for cooling water so as to regulate water quantity and
control the outlet temperature of cooled water at 20-40℃。Pay attention to the water
temperature not over 40℃so as to avoid producing sediment in a water tank.
10. An advance vacuum pump must be used as this pump’s fore pump which is not used alone. If
an oil-sealed mechanical vacuum pump is used as its pump, the two may be used in series
connection. So this pump is not suitable for drawing out the gases such as too much oxygen
content, explosiveness, corrosion to ferrous metal, chemical reaction to vacuum oil and containing
dust etc. Otherwise, the service life of a fore pump will be shortening.

②Check there have enough lubrication oil in end cover A and end covers B, make sure the oil
should be reached to the oil level of oil mirror. The oil cup of oil sealing should be filled full usually
and keep clean. New pump’s oil must be changed after operating30 ～50 hours. After then, the
oil can be changed according to the operating condition.
③if there have dust and other metal powder in the exhausted gas, anti-dust or filler devices
should be installed in front of air inlet port. If there have corrosive gas in exhausted gases, some
neutralizing measures should be adopted.
④Check there have no any loosening in various parts .Motor’s rotational direction should be
in accordance with arrow direction on a pump.
6.2 Starting

7. Maintenance & accessories
7.1 Safety information
The safety information was given in the following applies to all maintenance work.
Warning: Disconnect the electrical power before disassembling the pump and venting to
atmospheric pressure. Make absolutely sure that the pump cannot be accidentally started. If the
pump has been pumping harmful substances, determine the nature of hazard and introduce
suitable safety measure.
When drying or blowing out the pump with compressed air, technician must observe and obey all
safety regulations.
Caution: All maintenance and cleaning work described in this section must be only carried out by
the trained person.
When handling the used oil plus observe the relevant environment regulations.
Improper maintenance or repairs may affect the service life and pump performance.
7.2 Oil change/gear box
Warning: Before pumping oxygen or other highly reactive gases at concentrations which
exceeding 20% in the atmosphere will be necessary to choose a special pump. Such a pump have
to modified and degreased as well as a special lubricant oil. Bearings consume a little oil and the
gear under clean operating conditions. We recommend you to change the oil after the first 500hrs
operation to remove any wearing residue. Then, under the normal operating conditions, change
pump oil after every 3000hrs operating. Change oil much more frequently when pumping
corrosive vapors or large amount of dust or when happing from the atmospheric pressure to
working pressure usually.
Warning: Before removing the oil-drain/oil filling screw, the pump should be stooped at first and
vent to atmosphere pressure (have no vacuum inside pump chamber).
When the pump has become warm during operation, the casing and the oil temperature may
exceed 80 ℃, then should leave the pump to cooling down.
Always wear protective gloves to protect yourself against aggressive residues in the oil .
Loosen the oil-drain/oil-fill screw and then drain out the oil. Clean the sealing surface and firmly
reinstall the oil-drain screw using a gasket which is in a perfect condition. Wipe off any oil residues
from the casing. Fill in new oil. Make sure to use the right kind of oil.
Caution: We recommend the vacuum oil is N100 or N62. Make sure the oil level is correct .If the
oil level is too low, the bearings and gearwheels will not lubricated adequately; if it is too high, oil
may enter into the pump chamber. Clean the oil-fill port and reinstall the screw using a gasket
which is in a perfect condition.

13
www.bluelinevacuum.com
Caution: The oil fill port must be sealed tightly. Or the air will be entered into pump chamber
through impeller seals.
7.3 Oil Change/Shaft Seal Housing
Warning: The oil in the shaft seal housing should be changed every 3,000hrs operating. Loosen the
oil-drain screw under the shaft seal housing, drain out the oil and then screw the oil-drain with a
gasket which is in a perfect condition. Fill in fresh oil through the oiler and the oil should be
reached to the oil level. .
Maximum level:
When the pump is warm = 1/2 of the height of the oiler.
When the pump is cold = 1/3 of the height of the oiler. Wipe off any oil residues from the
casing.
7.4 Cleaning the Fan and the Cooling Fins
Warning: The fans slits as well as the motor fins will be polluted when working in humidity
conditions. In order to ensure a sufficient air enter into motor and the pump’s casing, the fan grids
must be cleaned using a cleaning brush when polluted. Any coarse dirt must be removed from the
motor fins and the pump.
7.5 Cleaning the Pumping Chamber
Warning: Under dirty operating conditions, pump chamber and rotor will be getting polluted.
After removing the two connecting lines, the contaminants can be blown out with dry compressed
air or flushed out using a suitable solvent. Contaminants that cannot be removing completely from
the pump chamber with a wire brush, metallic sponge or scraper. Then change the oil.
Warning: During cleaning, the rotors must be turned only by hand. The loosened parts must not
remain in the pump. After cleaning, check the pump by slowly turning the rotor. The rotor should
be moved freely and without any resistance.
