Stakpure Pure water system RO 50-80 ED ready with softener

This combination does not exist.

RO-ED ready pure water systems with ED cell, tank and pressure pump
The ready-to-connect pure water system from stakpure combines all treatment steps in one compact and low-noise unit. Pre-treatment, reverse osmosis, electro-deionisation for residual desalination, pure water tank and pressure boosting are integrated in a control cabinet to save space and are completely pre-assembled. Pure water units of the RO ED READY "to use" series produce pure water according to all common standards such as ASTM and DIN 285 + DIN EN 15883 and aqua purificata. Specially developed for the safe and economical supply of pure water to complete laboratory floors and AEMP's in medical practices and hospitals, as well as manufacturing plants in the food and pharmaceutical industries (aqua purificata for external parts cleaning), where space is still a scarce commodity. The clean water system is completed with a digital microprocessor control for display and control of all operating and performance parameters.

System design Pressure boosting
The PST 2500 PC pump station is a self-priming, horizontal, single-stage centrifugal pump with built-in ejector. The squirrel-cage motor and the use of a mechanical shaft seal make the unit maintenance-free and insensitive to faults. Long service life due to the use of stainless steel for all highly stressed parts, such as impeller and housing. In combination with the automatic pressure control, the unit becomes a complete supply station.
