HOUSTON -- A seal-less triplex diaphragm pump from Wanner Engineering has an OTC technology Spotlight Award. The Hydra-Cell T80 pump provides zero leakage, can run dry without damage, runs with closed or blocked suction, and can pump abrasive fluids, says Wanner.

The new design aims to provide performance without packing and plunger wear, leakage, external lubrication, and emissions, says Wanner. The T80 series uses asynchronous, hydraulically balanced, diaphragms with a patented valving system that allows the diaphragms to be hydraulically coupled to the displacing plungers with not mechanical coupling.

The Hydra-Cell displaces oil with three plungers and the oil flexes the diaphragms against the fluid being pumped.
