2033 - 2063 m3/h rotary vane pumps.
SD, C1, C2 Pascal series
The 33 to 63m3/h pump models,
have following main characteristics:
– A direct drive motor making
them very compact.
– An anti-suckback system
ensures the tightness of the
pump during accidental or
voluntary shutdowns.
– A gas ballast enables the
pumping of condensable vapors.
– The universal three-phase
motor can be disassembled
independently of the rest of
the pump, without the need to
drain the oil case.
– On the oil case, a sight glass
can be used to inspect the oil
level easily when filling the oil
case and during the operation of
the pump.
– A neutral gas purge is used
to degas oil and dilute pumped
gases on C1 and C2 series
models.
– An oil casing purge is used to
dilute the pumped gases on C2
series models.
– Sensor connections for oil
pressure or temperature sensors
are available on C2 series
models. The inlet and exhaust end fittings are PNEUROP ISO-KF standardized.
They can be used to connect many of our accessories (see page 14).
The main remplacement parts are interchangeable: This enables easier disassembly-
assembly operations and replacement without changing the pump’s performance.
Various accessories can be used to adapt the pump to meet the requirements of your
application.

Operating principle
of the rotary vane pump
The pumping cycle is
given below:
Inlet
Transfer
Compression
Exhaust
This is a volumetric pump, with a functional part composed of:
• A hollow cylindrical stator with inlet and exhaust valves.
• A rotor mounted eccentrically inside the stator for pumping.
• Two vanes sliding in the rotor, forced against the stator by centrifugal force and
springs.
Single-stage
rotary vane pump
As the vane passes in front of the inlet
orifice, an increasing space is formed into
which the gas from the chamber to be
evacuated expands.
When the second vane passes, the space is
closed.
The gas trapped in the space between the
two vanes is transferred to the exhaust
orifice as the rotor rotates.
The space communicates with the exhaust.
which is fitted with a valve: the gas is
compressed until the safety valve is opened.
The gas is expelled into the oil casing when
the pressure is sufficient to open the valve.

Two-stage
rotary vane pump
To improve the backing pressure and flowrate at low pressure, two stages are
connected in series. The second is similar to the first both structurally and operationally.
The gases pulled in by the first stage (low pressure) are transferred to the second stage
(high pressure) and discharged through the high pressure (HP) valve.
Applications Two stage rotary vane pumps are the best choice for application requiring an ultimate
vacuum as low as 5·10-3 hPa.
Note: when operating a two stage vane pump continously, greater than half an hour
- above 1 hPa,
- or with opened gas ballast,
the unit should be equipped with an oil mist eliminator equipped with an oil return
system.

Oil - Noise limiter - Antisuckback
Oil has several important functions in the pump:
– It lubricates mechanical components (bearings, seals, rotor, vanes, etc.).
– It makes moving parts relatively tight by limiting internal leakage.
– It carries away the heat produced by the compressed gases.
Oil
Choosing the right oil Not all oils produce the same ultimate pressure in a given pump. Ultimate pressure
depends on the saturated vapor pressure of the oil, its viscosity and its ability to dissolve
gases.
Good pumping conditions are related to the type of oil used. The choice depends on:
– Expected pump performance.
– Chemical aggression and corrosion of pumped gases.
– Accessories used.
– Desired maintenance intervals and total operating cost.
The manufacturer has selected various types of oil for its pumps (see page 18).

Lubrication The pump is equipped with a lubrication system which regulates the oil flow rate
required in the vacuum pump. In addition this system also ensures the gassing of
the lubrication oil and therefore the low noise level of the pump.
When the pump begins
to operate, the cooled
oil (from the bottom of
the oil casing) is pulled
in by the oil pump (2)
and drawn in through
the oil inlet tube (3). It is
then agitated by a venturi
tube (4) and forced
into the chamber (6)
which is adjusted by the
diaphragm spring system (7).
The discharge pressure of the oil pump (2) lifts the diaphragm off its seat (8) allowing
oil to reach the functional block via the oil injection line (through seats) (8). An orifice
(9) equipped with a jet located in the oil lubrification systems allows trapped gases to
be expelled out of the chamber (6).
C1 series
C1 series pumps are equipped with an automobile type oil filter, which traps particles
from the oil pumps exhaust. Due to its construction, its life time is reduced when
pumping on corrosive products in large quantities. In this case, an auxiliary oil filtering
system is recommended and the filter is replaced by a stainless steel short-circuit
stopper (see accessories page 14).

EN – 9
Parallel to the oil flow, there is a small orifice in the venturi tube (5), which reduces the
noise level at ultimate pressure. Because of the negative pressure created at the end of
the venturi tube (5), gases are entrained into the moving layers of oil dampening pump
noise, allowing the fluid to become more compressible.The added gases will affect the
ultimate pressure, therefore, a compromise between sound level and ultimate pressure
has to be reached as follows:
- Tightening down air intake tube (5) decreases the oil flowrate at the intake of the oil
pump (2) and increases the amount of gas mixture in the oil. The sound level decreases
but the ultimate pressure increases.
- Unscrewing tube (5) increases the oil flowrate at the intake of the oil pump (2) and
decreases the amount of air mixture with the oil. The sound level increases but the
ultimate pressure decreases.
This adjustment can be performed via the oil fill port while the pump is in operation at
ultimate pressure.
Anti-noise
Anti-suckback
and tightness at
stopping
When the pump is stopped or the power is turned off, the anti-suckback device (6),
(7) and (8) isolates the functional block of the pump against air or oil returning to the
chamber being evacuated.
When the pump stops, the discharge pressure of the oil pump (2) drops rapidly through
the jet (9). Diaphragm (7) under pressure from spring and the difference of pressure is
forced againts its seat (8) thus closing off the injection line through the seat (8).
The seal is also ensured by flush-mounted o-rings between the faces of the functional
parts (stators, flanges, housing...) and by spring loaded check valves in the discharge
ports.
Gas ballast When condensable vapors are being
pumped, gas is compressed beyond
its saturated vapor pressure in
the «compression» phase and
can condense, impairing pump
performance and life.
The gas ballast can be used to inject
a certain quantity of air (inert or dry
gas) into the last stage of the pump
during the «compression» phase so
that the partial pressure of the pumped gas is less than its saturated vapor pressure
at the temperature of the pump. Condensation is therefore impossible if this limit is
not reached.The maximum admissible vapor pressure is obtained at pump inlet for this
value.
At the end of «compression», the pressure in the exhaust chamber is greater than
atmospheric pressure. An anti-suckback device (valve + spring) prevents the gases and
oil from being draw back into the inlet.
The saturated vapor pressure of a body is higher when the system is hot than when
it is cold; therefore, the pump must reach operating temperature before pumping
condensable vapors.

Gas ballast (cont’d)
Using the gas ballast increases the ultimate pressure of the pump as well
as the temperature.
The gas ballast control, located on the frame cannot be used to set the gas
injection flow rate.
When the gas ballast control is open, the pump is not tight when stopped.
To guarantee this tightness, install an automatic gas ballast.
The functioning in permanent regime with opened gas ballast draws away
important oil losses (mist) by exhaust: use an accessory OME 40 HP + ODK
(see page 14) or control the oil level very often.
C1 and C2 pump series:
Because of the danger present if the gas ballast (C1 series) or purge gas
ballast (C2 series) was to be opened to atmosphere, remove the plug and
connect the port to a neutral gas supply line (see page 35).

When pumping on corrosive, aggressives or flammable gases, the gas can
cause injury or death. In these cases,
- connect the exhaust of the pump to an exhaust stack or an evacuation
duct.
- connect a relief valve or rupture disc directly on the pump. Contact your
closest service center (see addresses on our website).
When the exhaust is connected to an extraction duct or an oil mist
eliminator, you must remove the exhaust safety valve mounted in the
pump’s exhaust orifice.
At the pump exhaust, the discharge circuit must be such that the resulting
excess pressure in the oil case is as low as possible. The maximum excess
pressure recommended for correct pump operation is 500 hPa (6 PSI).
A slight negative pressure in the oil case (100 to 200 hPa / 1.5 PSI), at the
exhaust, will prevent gases from accumulating and reduce pump corrosion
and pollution.
For safety reasons, use accessories on the inlet and exhaust lines whose
materials and sealing properties are compatible with the gases being used.

installation and operation
Unpacking
Before switching on the equipment, the user must read all of the start-up
and operation sections of this operating manual and observe the safety
instructions listed in this operating manual.
The product is supplied with the inlet and exhaust sealed. These are to
prevent foreign bodies entering the pump during transport and storage.
C2 Series: In order to prevent moisture from entering the pump before
installation, it has been pressurized before hand with nitrogen and sealed
with blanking plates.
Do not remove these blanking plates until you are ready to install the
product on the vacuum line.
We took care to provide you with a clean product. To keep it in this
condition, unpack it only in its final place of use.
Make sure the equipment shows no sign of transport damage. If it has
been damaged, take the necessary steps to record this with the carrier
and inform the manufacturer. In all cases, we recommend keeping the
packaging (reusable materials) for further transport of the equipment or
for prolonged storage.
Vane roughing pumps use lubricants, it is recommended to request
information from the manufacturer on the safety data sheets concerning
the lubricant (MSDS available on our website).
The pumps are delivered without an oil charge: the oil is delivered in
separate containers.
In the same way, it is recommended to drain the pump before returning
the equipment.
Wear appropriated safety equipment to fill in or drain the oil in the pumps.
For all handling of the equipment, it is highly recommended to only
use the devices provided for this purpose (handle, hoisting rings, spring
hook..).
The spring hook and square support must not be used to tip up the pump
from horizontal to vertical position and vice versa.
The maker can not be held liable for the consequences of using other
handling devices.
Handling

EN – 16
All series
• After 3 months storage without oil, factors such as temperature, degree of humidity,
salt air, etc. may cause the deterioration of the pump components, particularly the
hardening of O-rings and the "sticking" of lip seals on shafts and the gumming of oil.
In this state, a pump may have operational problems, particularly oil leaks. Before any
start-up (new pump as well as used), the pump must be disassembled, and all the seals
changed. See the Maintenance instructions available on the website.
Pump which have been used:
If the pump is not new, drain and rinse it (see page 44). Fill it with new oil, then pump
a dry inert gas through it to remove all traces of dampness in the pumping system and
oil casing. Pump in dry inert gas as fallows:
- 10 minutes at above 30 hPa.
- 10 minutes at ultimate pressure with gas ballast open.
- 10 minutes at ultimate pressure.
Stop the pump and seal the inlet and exhaust orifices tightly with quick connect
clamps, centering rings, blank-off flanges...
Note:
The seal kits must be stored with caution. Keep them away from heat and light
(sunlight and ultraviolet light) in order to prevent the elostomers from hardening
(AFNOR standard FD T 46.022).
Storage
C2 series
All series
New pump:
If the pump is new and has not been unpacked, store it as received since it has been
pressurized with neutral gas at factory.
• If the pump is to be stored, we guarantee the reliability of our equipment without
particular storage precautions for up to 3 months (ambient temperature between 41 °F
and 149 °F (5 °C and 65 °C).
• For storage periods of over 3 months, we recommend to fill the pump with oil
during storage. For this, fill the pump and run it at ultimate vacuum (inlet orifice
blocked) for approximately 1 hour in order to lubricate all the parts of the functional
block (see page 29).
Then, stop the pump and store it with the inlet and exhaust orifices sealed: clamping
ring, centring ring, plug, etc.
The shaft must be rotated by hand (be means of the fan) or by starting the pump every
six months following this storage procedure.

Installation and
start-up
The pump must be operated in the horizontal position in support on its
base.
Ensure that the product is connected to an electrical installation:
- in compliance with the local and national safety requirements,
- equipped with electrical protection (fuses, circuit breaker, …) which has a
suitable earth (ground) point, properly connected.
Do not expose any part of the human body to vacuum.
The product is supplied with the inlet and exhaust sealed. Remove these
blanking plates when you are ready to connect the product on your
vacuum system.
As well as, don’t operate the product unless the inlet and exhaust are
connected to a vacuum and exhaust pumping line.
The products are designed to avoid subjecting users to heat hazards.
Specific operating conditions can nevertheless exist that require extra
caution from users due to the high temperatures generated (outer
surfaces > 70 °C):
Wear protective gloves to work on the product, especially during
maintenance.
Our pumps are tested in the factory with A120 oil or A119 for the USA (A113 oil for
the C2 series).
It is recommended to use the same oil during operation, because the oils are
not mixable (refer to table page 18 and remplacement fluids page 19).
• If changing the type of oil, refer to the chapter concerned for the procedure and the
type of lubricant required (see page 45).
