NEW patented DPC Technology protects
Hydra-Cell pumps from
abusive inlet conditions and extends pump reliability
Hydra-Cell D10 models are now equipped with Wanner Engineering's new patented DIAPHRAGM POSITION CONTROL (DPC) Technology. (#4 above) The Kel-Cell controls the position of the diaphragm under a wide variety of adverse inlet conditions and provides a new degree of diaphragm rupture protection. While following the standard installation guidelines for Hydra-Cell pumps is always recommended, Kel-Cell DPC equipped pumps will greatly reduce the possibility of an incidental failure of a diaphragm, should an unforeseen problem occur, such as:
Inlet pipe partially or completely blocked
Inlet filter partially or completely blocked
Inlet shut-off valve partially or completely closed
Inadequate liquid supply
Excessively viscous fluid
Any other condition which results in excess vacuum conditions on the inlet of the pump.
The Kel-Cell DPC system is an enhancement of existing Hydra-Cell technology. New pump parts include the cylinder housing, piston return spring retainer, valve plunger, sleeve valve and the sleeve valve spring. These parts combine to prevent air from building up in the pistons, and keep control of the diaphragm to prevent damage due to cavitation. Generally, in cases where poor inlet conditions could eventually lead to a diaphragm failure, the Kel-Cell DPC will prevent the failure from happening, so troubleshooting can focus on finding and fixing the system problem which caused the 'apparent' poor pump performance.
The Kel-Cell DPC is not a substitute for good system design, and Hydra-Cell standard installation guidelines should be followed to ensure consistent and reliable system performance.
NOTE: Hydra-Cell pumps not fitted with Kel-Cell technology are limited to 7" Hg vacuum on the inlet to prevent diaphragm failure.
This design will be available for all Wanner Hydra-Cell pumps in the near future.
