Corrosion resistant vacuum unit

When we use corrosion-resistant vacuum unit, we will add check valve. You may not know the reason. Next, Schindler vacuum pump will give you an analysis of why to add check valve to corrosion-resistant vacuum unit.

1. The main function of vacuum pump is to install check valve.

2. Protection system: at the moment of pump shutdown due to fault, the inlet and system connection of corrosion-resistant vacuum unit are in vacuum state, and the outlet is generally connected with the atmosphere. The pressure will bring water into the system and destroy the system vacuum. In order to protect the system, check valves are usually installed at the pump inlet and system connection.

3. In order to protect the pump body and other equipment, a check valve is usually installed at the outlet of the corrosion-resistant vacuum unit.

4. Now more and more corrosion-resistant vacuum units install the check valve at the outlet, which can protect the pump and system.
