Leybold Service
If a pump is returned to Leybold, indicate whether the pump is free of substances damaging to health or whether it is contaminated.
If it is contaminated also indicate the nature of the hazard. Leybold must return any pumps without a “Declaration of Contamination” to the sender’s address.
Disposal of waste oil
Under the amended law relating to waste disposal dated November 1, 1986 (valid in the Federal Republic of Germany) the disposal of used oil is subject to new provisions. According to legislation relating to waste disposal the so-called principle of causality is applied. Hence, anyone in possession of used oil is responsible for its proper disposal.
Used oils coming from vacuum pumps must not be mixed with other substances.
Used oils from vacuum pumps (LH-oils on the basis of mineral oils) having been affected by normal contamination due to oxygen from the ambient air, increases in temperature and mechanical wear, must be disposed of as used oil in accordance with the regulations. Used oils from vacuum pumps that have been contaminated by other substances must be labelled, stored and disposed of as special waste with reference to the kind of contamination.
When disposing of used oil please observe the safety regulations that are valid in your country.
In many countries proof of were the oil has finally been left is required by Law and often shipping of such contaminated waste requires permission by the authorities. Waste disposal information is available through:

1 Description
TRIVAC-B pumps are oil-sealed rotary vane pumps.The TRIVAC S 4 B and S 8 B are single-stage pumps, and the TRIVAC D 4 B and D 8 B are dual-stage pumps.The number in the type designation (4 or 8) indicates the pumping speed in m3x h-1.
TRIVAC-B pumps can pump gases and vapours and evacuate vessels or vacuum systems in the fine vacuum range. Those of standard design are not suitable for pumping greater than atmospheric concentrations of oxygen, hazardous gases, or extremely aggressive or corrosive media.
The drive motor of the TRIVAC-B is directly flanged to the pump at the coupling housing. The pump and motor shafts are directly connected by a flexible coupling.The bearing points of the pump module are force lubricated sliding bearings. All controls as well as the oil-level glass and the nameplate are arranged on the front. All connections are to be found at the sides of the pump. The oil-level glass is provided with prisms for better observation of the oil level.
The pump module consists of assembly parts which are pin-fitted so as to allow easy disassembly and reassembly. The pump module can be easily removed without special tools.
1.1 Function
The rotor (2/7), mounted eccentrically in the pump housing (2/6) (pump chamber), has two radially sliding vanes (2/5) which divide the pump chamber into several compartments. The volume of each compartment changes periodically with the rotation of the rotor.
As a result, gas is sucked in at the intake port (2/1).The gas passes through the dirt trap sieve (2/2), flows past the open anti-suckback valve (2/3) and then enters the pump chamber.In the pump chamber, the gas is passed on and compressed, after the inlet aperture is closed by the vane.
The oil injected into the pump chamber is used for sealing and lubricating. The slap noise of the oil in the pump which usually occurs when attaining the ultimate pressure is prevented by admitting a very small amount of air into the pump chamber.
The compressed gas in the pump chamber is ejected through the exhaust valve (2/10). The oil entrained in the gas is coarsely trapped in the internal demister (2/11); there the oil is also freed of mechanical impurities. The gas leaves the TRIVAC-B through the exhaust por t.
During compression, a controlled amount of air – the so­called gas ballast – can be allowed to enter the pump chamber by opening the gas ballast valve.

Fig. 1 TRIVAC-B with accessories
The gas ballast stops condensation of vapours in the pump chamber up to the limit of vapour tolerance as specified in the technical data for the pump (the data refer to water vapour).
The gas ballast valve is opened and closed by turning the gas ballast knob (7/5) on the front.
To enable the TRIVAC-B to be used at intake pressures as high as 1,000 mbar, a special lubricating system was developed featuring force-lubrication of the sliding bearings.
An oil pump (3/6) pumps the oil from the oil reservoir (3/5) into a pressure-lubrication system which supplies oil to all bearing points (3/2).From there the oil enters the pump chamber area (3/4) of the vacuum pump.
The oil pump is fitted in the front end plate on the coupling side of the pump module.The oil suction line is placed low, resulting in a large usable oil reser voir.
The oil is separated from the gas in the TRIVAC-B in two steps as described above. First, small droplets are coalesced into large drops in the internal demister (2/11) fitted above the exhaust valve (2/10). Then, the large drops fall into the oil reservoir as the exhaust gas is diverted by the inner walls of the oil case.Thus a low loss of oil is obtained. This and the large usable oil reservoir ensure long intervals between oil changes even at high intake pressures.
Description
The vacuum is maintained by the TRIVAC-B through an integrated hydropneumatic anti-suckback valve (2/3) which is controlled via the oil pressure.
During operation of the TRIVAC-B the control piston (4/3) remains sealed against a spring (4/2) by the oil pressure. The valve disc (4/6) of the anti-suckback valve is held at the lower position by its own weight (valve open). When the pump stops (because it has been switched off or because of a failure), the oil pressure drops and the spring (4/2) presses the control piston (4/3) up. Thus a connection is provided between the oil case or the oil reservoir (4/1) and the piston (4/4) of the anti-suckback valve. Due to the pressure difference between the oil case and the intake port the oil presses the piston (4/4) up and the valve plate (4/6) against the valve seat (4/5). The quantity of oil in the oil reservoir (4/1) prevents the entry of air into the intake port (2/1) at the beginning of this process.
After the oil has flowed out from the reservoir and when the valve plate rests on the valve seat, air follows in, which vents the pump chamber and forces the v alve disc (4/6) against its seat. This effectively prevents backstreaming of oil. The anti-suckback valve (2/3) operates independently of the operating mode of the pump, i.e.also with gas ballast.

1.5 Transportation
• Pumps which are filled with operating agents must only be moved while standing upright. Otherwise oil may escape. Avoid any other orientations during transport.
• Check the pump for the presence of any oil leaks, since there exists the danger that someone may slip on spilt oil.
• When lifting the pump you must make use of the crane eyes provided on the pump for this purpose; also use the recommended type of lifting device.
