How Water Conservation Systems Reduce Waste and Cost


In today’s environmentally conscious world, every drop of water is a precious resource. Conserving water in pumping and sealing applications is an effective—yet often underused—method of reducing both your costs and your environmental footprint.

Typical Plan 54 piping plans of piping water to and from a double seal use large amounts of water to operate. Flexaseal’s Water Conservation System (WCS2) is piped as a Plan 53A, which replaces the traditional Plan 54 for double seals by using the plant’s existing water line to pressurize the barrier fluid inside of the seal reservoir. The resulting pressurized barrier fluid maintains a cool, stable fluid film across the seal faces, increasing the longevity and mean time between failures of the seal.

The WCS2 system, which is excellent for wastewater treatment plants and paper mills, uses a check valve to protect the plant’s water line from contamination while allowing for the maximum pressure. The WCS2 system allows for pressure adjustments to arrive at the optimal engineering-recommended value. The included flow indicator provides a quick and simple visual representation of any inboard seal leakage.

The Water Management System is self-regulating, allowing for automatic refilling and re-pressurization if fluctuations occur. Barrier fluid is circulated between the WCS2 and the double seal via by the seal’s pumping ring and thermosyphon effects.

A Water Conservation System is a great choice to substantively reduce the cost of water usage, while utilizing existing plant water lines instead of requiring a potentially costly new dedicated pressurization system.
