HYDRA-CELL® TECHNOLOGY

Advanced Diaphragm Position Control

Protecting the Diaphragm from Closed Suction Line & Suction Line Vacuum Conditions

In normal operation, Wanner Hydra-Cell Pro® diaphragms operate in hydraulic balance. If there is a restriction in the suction line of the pump, the Advanced Diaphragm Position Control (ADPC) engages to protect the diaphragm from damage. If an operator runs the pump with a closed suction line isolation valve by accident, 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 continues to evolve the designs to improve the performance, security and peace of mind for customers.

Hydra-Cell G35 Restricted Inlet

Protection of Pump from Hydraulic End Cavitation

Cavitation of the hydraulic side of a hydraulically balanced diaphragm pump occurs when the diaphragm operates out of sync with the plunger, pressurizing the hydraulic oil. This can happen when there is not enough process suction pressure to push the diaphragm back and keep the diaphragm in sync with the drive plunger. The ADPC of Wanner Hydra-Cell Pro® pumps keeps the diaphragm in sync with the hydraulic drive plunger and protects the pump from Hydraulic drive cavitation and damage.

Self-Priming and Dry Suction Lift

Wanner Hydra-Cell Pro pumps can run dry indefinitely. This feature, combined with the pump's ability to pull approximately an 80% vacuum gives Hydra-Cell Pro pumps the ability to dry lift and self-prime.

Wide Range of Suction Pressures

Standard Hydra-Cell Pro pumps can operate from 0-34 barg, giving flexibility for many different applications and simplifying system design. For higher suction pressures please consult Wanner.

Diaphragm Leak Detection

If in the unlikely event that the diaphragm ruptures, Wanner Hydra-Cell Pro T & Q series and Metering Series pumps feature a detection mechanism that generates a signal which can be used to shut the pump down immediately.

Containment if Diaphragm Rupture

In many Wanner Hydra-Cell Pro pump models, if a diaphragm rupture is detected, the pump shuts down. The diaphragms are pulled into their back position, sealing off the process liquid.
