- Page 14 Technical Data When the vapour pressure of the sealing liquid is close to the process inlet pressure, the liquid sealing ring can start to boil and this may result in cavitation. (Cavitation occurs when vapour bubbles formed at the suction inlet are transferred to the discharge outlet, where the bubbles collapse under pressure with potentially destructive force).

- Page 32 Fault finding Fault Vacuum pumping performance is poor Cause The sealing liquid supply is inadequate, or the temperature is too high. Remedy Check that the sealing liquid supply is as specified in Sealing liquid supply page 13. Cause The direction of pump rotation is incorrect. Remedy Check the direction of pump rotation and correct as necessary.
- Page 33 Fault finding Fault The motor circuit-breaker trips when the motor is switched on Cause The motor winding is short-circuited. Remedy Check the motor winding. Cause The motor is overloaded. Remedy Reduce the liquid compressant flow. Cause The counter pressure in discharge is too high. Remedy Reduce the counter pressure.
- Page 34 Fault finding Cause The parts are corroded. Remedy Replace the corroded parts. Cause The mechanical seal is loose. Remedy Replace the mechanical seal. Fault There is an abnormal screeching noise Cause Pump cavitation. Remedy Connect the cavitation protection line. Cause The sealing liquid flow is too high.
- Page 35 Storage Storage 8.1. Preparation WARNING: USE PERSONAL PROTECTIVE EQUIPMENT If the pump has been used with a water-based sealing liquid, harmful bacteria may have propagated in the pump. Make sure that you wear the appropriate Personal Protective Equipment (PPE) when you prepare the pump for storage. Use the following procedure to remove the pump from your system for storage: 1.
- Page 36 Storage Note: If the pump is to be stored for more than 6 months, consult with us or the supplier. If the pump is to be stored for two months or more: 1. Drain the sealing liquid from the pump. 2.
- Page 37 Disposal Disposal WARNING: USE PERSONAL PROTECTIVE EQUIPMENT Risk of injury or damage to the environment. Ensure that you wear the appropriate Personal Protective Equipment (PPE) when you handle sealing liquid or components which have been contaminated with dangerous substances, or handle used water-based sealing liquid (which may contain harmful bacteria) or components contaminated with this sealing liquid.
