NM: 2 mbar - With Oil Return Line from oil sump to end plate.
F, G, H: 0,5mbar or lower - Oil Return Line with float valve from oil sump to inlet port of inlet flange.
1.0 INSTALLATION
1.1 Unpacking
nspect the box and pump carefully for any signs of damage incurred in transit. Since all pumps are
ordinarily shipped from our regional warehouse, such damage is the normal responsibility of the
carrier and should be reported to them.
The vacuum pump is bolted to the skid with studs that are connected through the rubber feet of the
pump. Remove the nuts from the underside of the crate and remove the pump. Unscrew the studs
from the rubber feet.
The inlet and exhaust of the pump are covered with caps to prevent dirt and other foreign
substances from entering the pump. Leave these caps in place until you are ready to pipe the pump
to your equipment.
1.2 Location
nstall the pump in a horizontal position on a level surface so that the pump can be evenly supported
on its rubber feet. Leave 30cm of access around the pump to allow proper cooling. Also adequate
ventilation must be provided for the fans, radiator and motor.
Allow access to the oil sight glass in order to inspect the oil level and the exhaust port for easy
access to change the exhaust Filters.
Do not tip the pump over if filled with oil.
1.3 Power Requirements
A schematic diagram for the electrical motor terminal connections is located in the junction box of
the motor or on the motor nameplate. Typical wiring for Three Phase Motors is as below:

Wiring Scheme- Single Phase Motor
The motor must be connected according to the electrical codes through a fused switch in order to
protect the motor against electrical or mechanical overload conditions. The overload of the motor
starter must be set at a level equal to the full load motor current listed on the motor nameplate.
f the pump is supplied with a motor starter it is preset at the factory according to customer
specifications. t is advisable to check that these settings are in line with the voltage at your location.
f the voltage is different, please contact Eurovacuum for motor and starter information.
Correct direction of rotation is marked by an arrow on the motor fan housing and is counter
clockwise when looking at the motor from the motor's fan side.
After electrical connections have been made, but prior to filling with oil, the rotation of the
motor should be checked. If backward, reverse any two leads of the three phase at the power
connection.
1.3 Vacuum Connections
Use a pipe size that is at least the size of the pump inlet connections. Smaller lines result in a
reduced pump capacity.
Pumps operating in parallel on a common main line should have a manual or automatic operated
shut-off valve or positive action check valve, installed in the suction line adjacent to the pump
suction flange. The built-in anti-suck back valve should not be used as a shut-off valve for the
vacuum system. Remove the protective cap from the inlet port prior to connection of pump to the
system.
Should process gas contain dust or other foreign particles, a suitable in line (inlet) filter should be
connected to the inlet port. Consult Eurovacuum for recommendations.
The vacuum piping should be designed to ensure that no liquids such as condensate or liquid
carried over from the process can reach the pump. f this possibility exists, a knock-out liquid
separator should be installed. Consult Eurovacuum for recommendations.
f an exhaust manifold is connected, install a drip leg and drain near the pump exhaust to prevent
exhaust condensation from entering the exhaust box. The following thread sizes are standard on the
Eurovacuum pumps (NPT thread is available upon request)

Pump Model Inlet Size Exhaust Size
EV-0010/0016/ 0021 ½" G 1¼” G or Open Grid
EV-0030/0040 1¼" G 1¼" G

EV-0160/0215 2" G 2" G
EV-0175/0250/0300 2" G 2" G
EV-0450/0500/0630/0750 3" G 3" G
1.4 Oil illing
The pump is shipped without oil. After level installation and correct rotation has been established, fill
the pump with recommended vacuum pump oil through the oil fill port. Oil level should be at the 3/4
positions on the oil sight glass.
Non-detergent oil should be used. We recommend original Eurovacuum Vacuum Pump oil.
Eurovacuum oil is a high quality vacuum oil that will provide longer running time between oil
changes, better lubrication at high operating temperatures and prolongs the life of the exhaust filter
elements. Oil detergent additives can cause exhaust filters to become clogged and shorten their
service life.
Depending on the ambient temperature around the pump, following oil is recommended.
Ambient Temp. Type of Oil For Model
0ºC~ 30ºC EV-Mineral Oil-32 EV-0010, 0016 & 0021
< 0ºC EV-Mineral Oil-32

3.0 OPERATION
3.1 Start-up
Check rotation of the motor as described in paragraph 1.3 Power Requirements.
Fill the pump with oil as described in paragraph 1.5 - Oil Filling
Start the pump with the inlet closed. Run the pump for a few minutes and then shut down. Check the
oil level again and make sure the oil level is between the 3/4 marks and full on the upper oil sight
glass.
Add oil, if necessary. Pump oil should only be added when the pump is off and circulating oil has
sufficient time to return to the oil sump.
f the ambient temperature is below 10°C, it is recommended to use a heater with thermostatic
control to warm up oil to room temperature. f necessary, the heater with control can be used to
keep the oil temperature at operating temperature for immediate start up with system where water
vapor comes in. Please consult Eurovacuum or representative for installation of a heater with
control.
3.2 Stopping the pump
To stop the pump, turn off the power. A built in anti-suck back valve will prevent oil from the oil
reservoir being sucked back into the cylinder after the pump is shutdown.
Do not utilize the anti-suck back valve as a check valve. Consult Eurovacuum for proper
check valves.
3.3 Gas Ballast
Most EV-series pumps are equipped with gas ballast. The gas ballast valve is located between the
inlet port and the exhaust box. ts main function is to prevent water vapour from condensing in the
pump that causes emulsification of the oil resulting in possible pump failure.
n applications, when the quantity of water vapour is moderate, it is recommended to run the pump
for 10 to 30 minutes to its normal operating temperature (about 75˚C), prior to going on process with
suction line shut off. The pump should also be operated off process for 10 to 30 minutes prior to shut
down. A slight air bleed (purge) is recommended during these 10 to 30 minute cycles to prevent the
vapour from condensing in the pump.
3.4 Check Valve (Built-In)
EV-series pumps are equipped with Built-in Check Valve. The valve is located in the inlet flange
housing, which is in the upper part of Pump module to prevent oil back to inlet side (system) when
the pump is running off.
(However, it is recommended to install separate check valve in the line of inlet if necessary)
3.5 Exhaust Pressure Gauge
This gage shall be installed on the Oil fill Plug for easy checking of status of saturation of the
exhaust filter．
f the reading is 0,6 Bar or higher, you need to change the exhaust filter(s) with new one(s).

4.0 MAINTENANCE
EV-Series vacuum pumps require very little maintenance. To ensure optimum performance, the
following maintenance steps should be followed:
4.1 Pump Oil
4.1.1 Oil Level
Under normal circumstances it should not be necessary to add oil between oil changes. A
significant drop in oil level means there is either an oil leak, a defective exhaust filter or O-ring, or
a leaking anti-suck back valve. f the pump is smoking excessively, the exhaust filter may be
installed improperly.
t is normal for the oil to be foamy or lightly coloured in an operating pump. This may be normal
aeration of the oil. f the oil appears milky or dark coloured, it is contaminated or burned and must
be changed.
Check the oil level only when the pump is shut off. Replenish oil if it drops below the ¼ mark of the
sight glass.
Caution: Do not add oil while the pump is running, since hot oil can escape from the oil fill port.
4.1.2 Oil Type and Quantity
See section 1.5 - Oil Filling - for details on oil type and quantity
4.1.3 Oil Change
Oil life is dependent on the operating conditions. A clean and dry air stream and operating
temperatures below 100˚C are ideal. When using proper Vacuum Pump Oil, it is recommended to
change the oil every 500-1000 operating hours or after half year. Oil life can be shorter than 500
hours if the pumps are operated under unfavorable operating conditions Oil change frequency is
dependent upon the application and ambient temperature. t is recommended that the customer
monitor the condition of the oil during this period.
Caution: Always change the oil when the pump is off but still at working temperature.
hen disposing of used oil, please observe the relevant environmental regulations.
4.1.4 Oil Spin-On ilter
Replace automotive-type spin on filter at every oil change.
Pump Model Part No.
EV-0030 ~ EV-0100 006010000
EV-0160 ~ EV-0300 050010000
EV-0450 ~ EV-0750 120010000
4.2 Inline (Inlet) ilter
Check inline (inlet) filter on a weekly basis. The filter cartridge should be cleaned or replaced when
dirty. Consult Eurovacuum for replacement element information.
Caution: Depending on the mounting position of the filter, be careful not to allow
accumulated foreign material to fall in the pump suction inlet when removing the filter
cartridge. Horizontal filter installation is recommended to prevent this.

4.3 Exhaust ilter
Replace these filters every 9 to 18 months of operation or as necessary. The service life of these
filters varies depending upon the application and frequency of oil change. t is necessary to change
these filters only when they become clogged. ndications of clogged filters are smoke or oil mist
coming from the exhaust of the pump, higher than normal motor current, and the exhaust pressure
gauge reading 0,6 bar or greater.

n cases where the vacuum level of the process is causing a large quantity of oil mist exhausting from
the pump, it is possible to mount the 1200120A0 filters inside of the EV-0175, 0250 & 0300 pumps.
Do not clean or re-use these filters. ilters must be disposed of in a proper way as they might
contain toxic substances carried over from the process. Replace O-rings on filter when
changing.
4.4 Gas ballast filter
Replace or clean the filter every as necessary or annually.
Type: 1) EV-0030 to 0100: Gas ballast without valve with paper filter - Replace paper filter
2) EV-0160 to 0750: Gas ballast with valve & sponge filter – Clean/replace the sponge filter
