Double diaphragm systems

Improved operating safety with diaphragm dosing pumps

The diaphragm dosing pumps are designed in such a manner in the standard version that a leakage following a wear-related diaphragm rupture is drained in a targeted manner. To increase the operating safety and to avoid damage to the environment from leakages in event of diaphragm damage, a double-diaphragm system is available for the Lutz-Jesco diaphragm dosing pumps.

• Plastic intermediate flange with glycerol as separating agent
• A wear-related failure of the dividing membrane does not lead to the immediate failure of the dosing pump, but can be detected via a diaphragm rupture sensor (two-rod electrode) via measurement of the conductivity.
