Our Technology Advantages - Creating Real Value for Our Customers

 

Advanced Diaphragm Position Control (ADPC) - Hydra-Cell® MT Series Metering & Dosing API675 Pump

 
 

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

 

In normal operation the Hydra-Cell® Metering & Dosing pumps 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, with continuously improving the designs and patents to improve the performance, security and peace of mind for our customers.

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 pressurising 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 the Hydra-Cell® Metering & Dosing 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

 

The Hydra-Cell® Metering and Dosing pump can run dry indefinitely, this combined with the pump's ability to pull approximately an 80% vacuum gives the pump the ability to dry lift and self prime.

 
 
 

Wide Range of Suction Pressures

 

The Hydra-Cell® Metering and Dosing pump can operate from negative 0.5 barg to plus 34 barg, giving flexibility for many different applications and simplifying system design. For higher suction pressures please consult Wanner International.
