Gecko Maelstrom CMS-1 Circulation Pump

The Gecko Maelstrom CMS-1 is a single-speed, 0.12 HP (90W) circulation pump designed as a direct replacement for the Aqua-Flo Circ-Master 1/15. It features a rotatable wet-end, 1.5-inch external thread plumbing connections, and delivers a maximum flow rate of 260 LPM with a maximum head pressure of 2.53 m. Operating at 230 V, 50 Hz and drawing 0.89 A, it runs quietly at 44 dB. Slight plumbing modifications may be necessary due to dimensional differences.

If you want to use a Gecko Maelstrom CMS-1 to replace an old Gecko Circ-Master, please use the fitting adapter PW-20027 as the height of the Maelstrom is lower than the older Circ Master model.
