These engineered devices have few moving parts, require virtually no maintenance and have decades of proven reliability. Here’s how they work:
Your return or closed loop pump’s water is plumbed to the OM drum, which is totally enclosed in a non-corrosive housing. The drum is driven by an external magna-drive motor which rotates the drum, opening and closing the 4 ports that send the flow to your tank. Every 15 seconds the flow direction changes – 24 hours a day, 7 days a week, 52 weeks a year. Every 15 or 30 seconds, depending on the drum design you choose, your flow of return or closed loop pump water is redirected to your tank from a different angle, a different direction and in differing strengths – replicating natures erratic flow patterns.
