The TRIVAC S16 B and S 25 B are single-stage pumps, and the TRIVAC D16 B and D 25 B are dual-stage pumps. The number in the type designation (16 or 25) indicates the pumping speed in m3 · h-1. TRIVAC-B pumps can pump gases and vapours and evacuate vessels or vacuum systems in the fine vacuum range.

The max. amount of heat given off approximately corresponds to the rated motor power. 2.
Operation The maximum throughput of the pump is equivalent to the pumping speed of the pump (see Section 1.6). Caution The cross-section of the intake and exhaust lines should be at least the same size as the connection ports of the pump. If the intake line is too narrow, it reduces the pumping speed. If the exhaust line is too narrow, overpressures may occur in the pump; this might damage the shaft seals and cause oil leaks. The maximum pressure in the oil case must not exceed 1.5 bar (absolute).
Operation Star connection Delta connection Fig. 8 Connection diagram for TRIVAC-B with 50 Hz 3-phase motor 2.3.2 Pump with Three-Phase AC Motor TRIVAC-B pumps with a three-phase motor are supplied without accessories for electrical connection. They must be connected via the appropriate cable, and a suitable motor protection switch. Set the switch in accordance with the rating on the motor nameplate. Fig. 8 shows the connection for pumps with 230/400 V, 50 Hz motors.
Operation 2.4.1 Areas of Application Caution The pump is not suitable for pumping of: - ignitable and explosive gases or vapours - oxidants - pyrophorous gases. The pumps are not suitable for pumping of liquids or very dusty media. Suitable protective devices must be installed. Our technical sales department is available for further advice in these matters. 2.4.
Operation 2.5 Operation TRIVAC-B pumps can pump condensable gases and vapours, provided that the gas ballast valve (7/5) is open and the pump has attained its operating temperature. 2.5.1 Pumping of Non-Condensable Gases If the process contains mainly permanent gases, the pump may be operated without gas ballast, provided that the saturation vapour pressure at operating temperature is not exceeded during compression.
Operation 2.6 Switching Off/Shutdown Under normal circumstances, all that you need do is to electrically switch off the TRIVAC-B. 2.6.1 Shut-Down through Monitoring Components Caution No further measures will be required. When pumping condensable media let the pump continue to operate with the gas ballast valve open and the intake line closed before switching off (see Section 2.5.2). When pumping aggressive or corrosive media, let the pump continue to operate even during long non-working intervals (e.g.
Operation 3 Maintenance Caution Disconnect the electrical connections before disassembling the pump. Make absolutely sure that the pump cannot be accidentally started. If the pump has pumped harmful substances, contrary to what has been stated in Section 2.4, ascertain the nature of hazard and take adequate safety measures. Observe all safety regulations. If you send a pump to LEYBOLD for repair please indicate any harmful substances existing in or around the pump.

For proper operation of the pump, it is essential that the pump has an adequate supply of the correct and clean oil at all times. Remove the oil-fill plug (9/1) and fill in with fresh oil.

A wire-mesh sieve is located in the intake port of the pump to act as a dirt trap for coarse particles. It should be kept clean to avoid a reduction of the pumping speed.

Required tools: If the centering disk is stuck, screw the capscrews (12/10) into the jackscrew holes in the centering disk.
Maintenance If you do not have a shaft seal driver, place the shaft seal on the centering disk and carefully force it in with light blows of the plastic hammer. The shaft seal must not be bent. Carefully push the O-ring (12/7) and the bushing (12/6) onto the shaft. Push the centering disk (12/1) with the shaft seal onto the shaft and up against the end plate; fasten it with the hex. socket screws (12/10). Insert the key (12/5). Mount the pump-half of the coupling (12/4) on the shaft.
