2. General description
2.1. Overview
WARNING: INCORRECT USE OF EQUIPMENT
Risk of injury or damage to the equipment. Incorrect use of the equipment can cause
damage to the equipment or injury to people. The user is responsible for the safe operation,
installation and monitoring of the system.
CAUTION: GAS BALLAST INSTALLATION
Risk of damage to the equipment. If water vapour is present within the system or is pumped
by the product the gas ballast must be used to prevent damage to the product. The gas
ballast should continue to be applied with the pump running, for at least 1 hour after the
water vapour source has been removed to enable the pump to dry.
The MSR 90 is a dry, multi-stage roots vacuum pump that offers high pumping speed in a
compact form. The pump is connected by a power cord and is designed for use on clean duty
applications.
The cord rating is:
Supply voltage (V) Current (A) Frequency (Hz)
200 ‑ 240 7 50 or 60
The pump is not designed for use with flammable, corrosive, toxic or other hazardous gases.
Gas or oxygen can mix in the pump system.
The dry pump can be used in either transient or steady state gas load conditions. The pump
can sustain operation with a maximum continuous power consumption of 850 W. If the gas
load causes this value to be exceeded, then the pump will temporarily slow down. If the load
is subsequently reduced; or the transient overload protection has recovered, then the pump
will return to full speed operation. Refer to Table: Performance data for information on
maximum inlet pressure.
Refer to Figure: Pump features, the system is supplied with a NW40 inlet port (1) and a
NW25 exhaust port (10).
The pump mechanism is operated by an electric motor driven by an internal pump controller.
The rotational elements of the pumping mechanism are simply supported at the end by
lubricated bearings. PFPE lubricant is used and this is contained in both the gearbox and
motor ends of the pump module. These are "sealed for life" and the lubricant does not need
to be replaced until the pump service interval is reached.
The system is air cooled by a fan installed internally in the pump enclosure. The pump has a
thermal protection device that will stop the motor if a thermal overload occurs, for example in
high ambient temperatures. You must restart the pump after the pump is cooled down.
The pump is designed to pump the residual gases used in high vacuum systems. The gases
are:
▪Air
▪Oxygen (O2) < 21% by volume
▪Nitrogen
▪Krypton
▪Argon
Operator Guide
RUO-IDV-05-13982-A
SCIEX Dry Pump MSR 90
Page 8 of 40

▪Helium
You can use the pump to pump water vapour. You must use the gas ballast when water
vapour is pumped. The water vapour must not condense in the pump.
Note:
Make sure that the water vapour does not condense inside the pump.
To use the pump for a gas that is not listed, contact the supplier for advice. Failure to contact
the supplier can invalidate the warranty of the pump. Do not use the pump for aggressive or
corrosive gases.

2.2.1. Auxiliary connector socket
An auxiliary control connection on the rear panel controls an optional inlet valve. This inlet
valve can be operated in parallel with the normal pump output signal. Refer to Figure: Pump
features, (7). The valve is usually closed and:
▪will open when the normal signal becomes active (pump at speed)
▪will close when you select the stop button or if there is a fault condition
The reaction time will be in line with the valve selection and the output signal is 24 V d.c.
Refer to Figure: Valve connector for polarity of the connector pins when the connector is
energized.
The auxiliary connector is regulated to 24 V d.c. to control the accessories. If the auxiliary
load current exceeds the value in Table: Auxiliary load currents, the output will shut down to
protect the pump controller. Refer to Table: Recommended mating connector for the
recommended mating plugs.

3.4. Electrical data
If the pump is operating with a supply voltage below the nominal operating range, example
< 200 V, the product will limit the maximum power deliverable to the pump motor. If the
application load exceeds the maximum power available, pump rotational speed will be
reduced. Refer to Figure: Speed vs Power graph. At lower rotational speeds pumping
performance will be impaired; however, the product can still pump down chambers or operate
in steady state conditions.

carrier immediately. Give the supplier and the carrier the information that follows:
▪part number of the pump
▪serial number of the pump
▪order number
▪supplier's invoice number
4. Do not use the pump if the pump is damaged.
5. If the pump is not to be used immediately, store the pump in the conditions given in
Storage on page 38.
6. The pump is supplied with sealed inlets and outlet to prevent the entry of dust and vapor.
Do not remove the seals until the pump is ready to be installed on the vacuum system.
4.3. Mechanical installation
WARNING: HEAVY OBJECT
Risk of physical injury. Use suitable equipment to lift the pump.
WARNING: LOOSE CABLES/PIPEWORK
Tripping hazard. Make sure that any cables and/or pipe work attached to the pump are fixed
carefully to avoid a slip/trip hazard and to prevent any damage to the cable.
WARNING: LIFTING EYE INTEGRITY
Risk of injury or damage to equipment. Make sure that the maximum angle between the
paired slings used to lift the system is 45 degrees. Increased angle could compromise the
lifting eye integrity.
WARNING: INSTALLATION SAFETY
Risk of injury or damage to equipment. Install the pump in the vacuum system before you
connect the pump to the power supply. This will make sure that the pump is not operated
causing injury to people, during installation.
WARNING: STATIC PRESSURE
Risk of damage to equipment. Do not step or stand on the pump, it is not designed to
withstand large static loads.
WARNING: HEAVY OBJECT
Push-pull hazard with strain injury. Push or pull the pump system only for short distance and
over flat surfaces. Lift the system if the floor is uneven or has obstacles.

WARNING: EXHAUST BLOCKAGE
Risk of injury or damage to equipment. A peak pressure of 3 bar(g) can be generated in the
pump if the exhaust or pipework attached to the exhaust are blocked.
WARNING: INSTALLATION SAFETY
Risk of injury or damage to the environment. Follow all local legislation when the pump is
installed or removed to reduce the impact of the pump on the environment.
CAUTION: CONDENSATE DRAINAGE
Risk of damage to equipment. Use a catchpot to prevent the drainage of condensate back
into the system. Condensate that drains back into the system could damage the pump.
Obey the instructions that follow when you install the pump:
▪Make sure that there is no blockage to access the pump electrical supply cable or the
other controls.
▪Make sure that there is a minimum air gap of 100 mm on all sides of the pump to allow
effective air circulation.
▪Make sure that the system is on a firm and levelled surface that can support the mass of
the pump.
▪Make sure that the system is installed away from combustible materials.
▪Level the pump to a maximum of 5 degrees (measured at the pump inlet).
▪You must do a risk assessment of the location and make sure that you can move the
pump safely and as per the local and national manual handling guidelines.
To move the pump:
1. Use suitable lifting equipment attached to lifting eyebolts (Figure: Pump features, (13)) to
move the dry pump system close to its final operating position. Refer to Table: Mechanical
data for pump mass.
2. Secure the dry pump system with the rubber stand-off and two small castors (Figure:
Pump features, (5)).
3. Remove the plastic caps from the inlet and exhaust before you connect the pump to the
vacuum system. Use appropriate NW vacuum fittings for connection to the system.
Obey the instructions that follow when you connect the pump to the vacuum system:
▪Connect the pump to an exhaust line to minimize the noise and the exhaust emissions.
▪Make sure that the pipeline connected to the pump inlet is as short as possible. Make
sure that the pipeline has a minimum internal diameter to get maximum pump speeds.
▪Put support under the vacuum pipeline to prevent the load on the coupling joints.
▪Make sure that the pump exhaust line is not blocked as a pressure of 3 bar(g) can be
generated in the exhaust pipework. Connect the pump with appropriate pipework and
fittings.
▪If necessary, install flexible bellows in the system pipelines to reduce the transmission of
the vibration and to prevent the load on the coupling joints. The pressure rating of the
bellows must be higher than the highest pressure generated in the system. We
recommend that you use the manufacturer's bellows.
