Suction pressure regulator

Constant suction pressure and leakage protection

The suction pressure regulator is a spring-loaded diaphragm valve that is opened by the effect of the pump suction pressure. This ensures that no medium can flow if the pump is not running or cannot generate a vacuum due to a line break.

• Protection of the dosing pump against excessive inlet pressure due to high containers or supply from pressure lines
• Used as a container outlet safety device in the event of a diaphragm rupture or line break and to prevent siphoning
• Prevents the influence of changing positive and negative feed heights on the dosing accuracy
• Protection of the dosing pump against pressure peaks caused by acceleration in long suction lines
