All Hydra-Cell pumps feature a diaphragm protection system to safeguard the diaphragms against abnormal or adverse conditions. Most Hydra-Cell models feature the patented Kel-Cell® or new Advanced Diaphragm Position Control (ADPC) technology. Others use an exclusive underfill/overfill valve system. They are designed to protect against:
- Partially or completely blocked inlet pipe or inlet filter.
- Partly or completely closed inlet shut-off valve.
- Inadequate liquid supply.
- Excessively viscous fluids.
- Inadequate discharge pressure.
- Other conditions that result in excessive vacuum formed at the inlet of the pump.
Diaphragm positioning systems protect diaphragms on most Hydra-Cell models.
These conditions can result from system problems, poor system design, faulty installation, an unplanned operational incident, or other situations that would cause the diaphragms to operate out of hydraulic balance and ultimately deform and rupture.
Hydra-Cell Metering Solutions model MT8 is one of the Hydra-Cell pumps to feature the underfill/overfill valve system.
Kel-Cell and ADPC positioning systems stabilize the diaphragms in all such conditions and virtually eliminate the possibility of an incidental diaphragm failure caused by adverse conditions.
The underfill/overfill valve ensures optimum actuating oil on every stroke for continuous accuracy and protection of the pump and diaphragm.
