Vacuum Pump Classification By Performance Q & A

Question: What is main suction pump?

Answer: In the vacuum system, the vacuum pump used to obtain the required vacuum degree is called main suction pump.

 

Question: What is a rough suction pump?

Answer: Starting from atmospheric pressure, rough suction pump is the vacuum pump that reduces the pressure of the system to the vacuum pump that starts to work in another pumping system. 

 

Question: What is the backing pump? 

Answer: A vacuum pump that maintains the backing pressure of another pump below its maximum allowable backing pressure. The backing pump can also be used as a rough suction pump.

 

Question: What is a maintenance pump?

Answer: In the vacuum system, when the pumping volume is very small, the main backing pump cannot be effectively used. For this reason, an auxiliary backing pump with a smaller capacity is configured in the vacuum system to maintain the normal operation of the main suction pump or maintain the low pressure vacuum pump required for the container.

 

Question: What is a rough (low) vacuum pump?

Answer: Starting from atmospheric pressure, a rough (low) vacuum pump reduces the pressure of the container and works in a vacuum pump in the low vacuum range.

 

Question: What is a high vacuum pump?

Answer: A vacuum pump that works in the high vacuum range.

 

Question: What is an ultra-high vacuum pump?

Answer: A vacuum pump that works in the ultra-high vacuum range.
