NOTETechnical term.

In this instruction manual, we consider that the term ‘machine’ refers to the ‘vacuumpump’.

2.1 Operating PrincipleWater-cooled version with direct cooling:

Water-cooled version with plate heat exchanger (optional):

The machine works on the one-stage, twin-screw pump principle.

Two screw rotors are rotating inside the cylinder. The pumped medium is trappedbetween the cylinder and screw chambers, compressed, and transported to the gas out-let. During the compression process, the two screw rotors do not come into contact witheach other nor with the cylinder. There is no need for a lubrication or an operating fluidin the compression chamber.

2.2 ApplicationThe machine is intended for the suction of air and other dry, non-aggressive and non-toxic gases.

Explosive gases and vapour mixtures can be drawn according to the scope of the Direct-ive ATEX 2014/34/EU.

It is necessary to check and ensure that the process media is compatible with the pumpmaterials and that the explosion protection will not be compromised e.g. by corrosion. Ifnecessary, contact your local Busch representative.

Depending on the equipment, the machine is intended for suction of explosive gases ac-cording to the data given on the nameplate of the machine (NP), see Explanation ofATEX Classification [► 11].Conveying of other media leads to an increased thermal and/or mechanical load on themachine and is permissible only after a consultation with Busch.


0870203597_NC0100-0300B_WCV_Ex_-0001_IM_en 9 / 60

The machine is intended for the placement in a potentially explosive environment ac-cording to the data given on the nameplate of the motor and the nameplate of the ma-chine (NP), see Explanation of ATEX Classification [► 11].In case Busch delivered the machine without motor and coupling, the following must beobserved:

• In regards to its explosive atmosphere protection class, the motor and the coup-ling must have at least the same ATEX classification as the machine for the outsidearea “Outside (o)”.

• The motor and the coupling do not require an ATEX certification when the ma-chine ATEX classification corresponds to “Outside (o) No ATEX zone”.

The machine is capable of maintaining ultimate pressure, see Technical Data [► 55].The machine is suitable for continuous operation.

Permitted environmental conditions, see Technical Data [► 55].

2.3 Start ControlsThe machine comes without start controls. The control of the machine is to be providedin the course of installation.

The machine can be optionally equipped with a starter unit or a variable-frequency drive.

2.4 Standard Features

2.4.1 ThermometerThe thermometer allows a visual display of the cooling water temperature in the coolingwater chamber.

2.4.2 Sealing SystemsThe machine is equipped with labyrinth seals on the motor side and suction side.

Other sealing systems are optionally available, see Mechanical Seals [► 10] or PTFEShaft Seals [► 11].Sealing systems prevent the process gas going to the bearings chambers.

2.4.3 Barrier Gas SystemThe barrier gas system allows the supply of compressed air or nitrogen into the motorside shaft seals in order to improve the sealing efficiency.

2.4.4 Nitrogen PanelThe nitrogen panel fitted to the base frame allows the supply of nitrogen to a number ofdifferent points on the machine.

Each device consists of a pressure regulator and a flow meter to adjust pressure andvolume flow separately.

The following devices are available:

– The barrier gas system for sealing systems on motor side. This device is equippedwith a flow switch integrated to the flow meter to switch off the machine if the ni-trogen volume flow drops below the minimum set flow value.

With gas lubricated double mechanical seals, the machine must be switched off if thenitrogen volume flow goes over the maximum set flow value.


10 / 60 0870203597_NC0100-0300B_WCV_Ex_-0001_IM_en

– The dilution gas ballast prevents the formation of condensates or dilutes them, de-pending on the application. The nitrogen is fed into the cylinder.

– The purge gas system fitted at the inlet flange allows to flush the machine after useor during operation. The nitrogen is fed into the inlet flange.

2.5 Accessories

NOTEDepending on the ATEX classification of the machine, some of the following accessoriesmay be mandatory, see ATEX Classifications and Associated Accessories [► 12].

2.5.1 Gas Ballast ValveThe gas ballast valve mixes the process gas with a limited quantity of ambient air tocounteract the condensation of vapour inside the machine.

The gas ballast valve has an influence on the ultimate pressure of the machine, see Tech-nical Data [► 55].

2.5.2 SilencerA silencer at the discharge connection (OUT) can be provided to reduce the exhaust gasnoise.

A non-return flap can be optionally added to the silencer.

2.5.3 Resistance ThermometerThe resistance thermometer monitors gas temperature. It can be installed at three differ-ent places depending on the ATEX classification.

Warning and trip signals must be set, see Wiring Diagram Resistance Thermometer[► 33].

2.5.4 Pressure TransmitterThe pressure transmitter monitors the gas pressure at the discharge connection (OUT).

Warning and trip signals must be set, see Wiring Diagram Pressure Transmitter [► 34].

2.5.5 Pressure SwitchThe pressure switch monitors the gas pressure at the discharge connection (OUT). It canbe installed instead of the pressure transmitter.

The machine must be stopped when the gas reaches a certain pressure, see Wiring Dia-gram Pressure Switch [► 34].

2.5.6 Mechanical SealsThe sealing systems can be equipped with mechanical seals. The following variants arepossible:

– Oil lubricated single mechanical seals on the motor side and labyrinth seals on thesuction side.

– Oil lubricated single mechanical seals on the motor side and suction side.


0870203597_NC0100-0300B_WCV_Ex_-0001_IM_en 11 / 60

– Gas lubricated double mechanical seals on the motor side and oil lubricated singlemechanical seals on suction side.

The gas lubricated double mechanical seals require a pressure switch in order to monit-ors if the gas pressure drops below the minimum allowable pressure. See Wiring Dia-gram Pressure Switch (With Gas Lubricated Double Mechanical Seals Only) [► 36].

2.5.7 PTFE Shaft SealsThe sealing systems on the motor side can also be equipped with PTFE shaft seals.

2.5.8 Terminal boxThe machine can be optionally equipped with one or two terminal boxes. All electricaldevices, except the motor, are already wired to the terminal box.

2.5.9 Flame ArrestersThe flame arresters are safety devices. They do not prevent explosion but avoid thepropagation of a deflagration within the machine compression chamber to the up anddownstream lines of the system.

To avoid a loss of suction capacity through the flame arrester at the machine inlet, a by-pass connection with a ball valve can be optionally delivered, see Flame Arrester BypassConnection (Optional) [► 25].

2.6 Explanation of ATEX ClassificationThe ATEX classification is written on the nameplate of the machine (NP), see below amarking example:

2.6.1 ATEX NameplateThe machine has two different nameplates:

– A nameplate (NP1) is fixed on the base frame of the machine with the ATEX markinginscription.

– A second nameplate (NP2) is fixed on the machine stage (module) identifying thatthe stage is suitable for ATEX certified machine.

This allows the preservation of the machine ATEX certification if the machine stageshould be replaced.
