Product Description | 2 Operating liquid control valve (OPC) allows the operating liquid flow rate to be regulated for opti- mum performance of the system, with compound pressure gauge (CG) indicating the operating liq- uid pressure at the vacuum pump inlet. The suction non-return valve (NRV) prevents operating liquid from flowing back into the process when the system stops under vacuum. -

Commissioning | 7 Commissioning CAUTION During operation the surface of the machine may reach temperatures of more than 70°C. Risk of burns! ● Avoid contact with the machine during and directly after operation. NOTICE The machine is running without operating liquid system. Will ruin the machine in short time! ●... - Page 20 7 | Commissioning The working pressure of the vacuum pump shall therefore be sufficiently above the vapor pressure of the operating liquid. In particular the pressure control in the vacuum system must by no means be achieved by throttling or even closing of the suction line! The vapor pressure of the operating liquid and consequently the ultimate pressure can be reduced by cooling.
