Leakage problem eliminated

Oxygen scavenging chemicals such as sodium and ammonium bisulfites are renown for damaging pumps. Occidental Petroleum had trialled several types of pumps and all were found wanting, the majority springing leaks through dynamic seals in a matter of days or weeks. A Hydra-Cell P200 with mechanical speed control has however solved the problem.

The seal-less design of this multi-diaphragm pump removed the leakage problem completely, reducing downtime and eliminating seal maintenance at a stroke.
