Advanced Diaphragm Position Control


Our Technology Advantages - Creating Real Value for Our Customers


Advanced Diaphragm Position Control (ADPC) - API674 & API675 Injection, Transfer and Dosing Seal-less Pumps


Protecting the Diaphragm from Closed Suction Line


In normal operation the Hydra-Cell® diaphragms operate in hydraulic balance. If there is a restriction in the suction line of the pump the Advanced Diaphragm Position Control (ADPC) comes into play and protects the diaphragm from damage; obviously the discharge flow rate is effected.

If an operator runs the Hydra-Cell® pump by accident with a closed suction line isolation valve, the diaphragms are not damaged.

If there is a vacuum condition on the suction of a running pump the ADPC keeps the diaphragm safe from rupture.

Wanner first introduced this patented technology in 2003 and still continues to improve the designs and patents to improve the performance, security and peace of mind for our customers.
