Gecko Maelstrom MS-1 3.0HP/4.2HP single-speed pump

This product is obsolete or unavailable.

Scroll down for replacement options.

Description

No Longer Sold or Recommended - Gecko's Maelstrom MS-1 single-speed spa pumps are being sold as 3HP and labelled as 4.2HP, but as they are only a 1700W pump, they are actually closer to 2.3HP in reality. 

We recommend other pumps with "true" HorsePower ratings, and in which you can easily get spare parts for. Perfect replacement is the Spatex SX250 here.
