What makes the Hydra-cell different
Generically different from other types of pump, the Hydra-Cell has a simple, rugged build in which elastomeric diaphragms; flexed sequentially by hydraulic pressure, provide the pumping action. They also isolate hydraulic fluid in the drive end from whatever fluid is to be pumped. The pump's few wetted parts are available in a variety of materials compatible with almost any liquid — hot or cold.
There are no dynamic seals in the pump and the diaphragms operate in hydraulic balance, unstressed even at high pressures. Under abnormal system conditions, such as partial vacuum, which can occur, if an inlet filter becomes blocked, Wanner's patented Kel-Cell feature protects the diaphragms against rupture, allowing the pump to run dry without damage.
This unique combination of features underlies the versatility of the pumps and enables them to meet apparently conflicting needs at the same time.
- uses less energy,
- needs less maintenance,
- easier to design-in,
- less bulky with a smaller footprint,
- easier and less expensive to control accurately over a wide turndown range,
- delivers a smoother flow, with lower pulsation and reduced need for dampeners
