Meet the Gecko AquaFlo Flo-Master FMVP 1.0 HP Wet End — a purpose-built spa pump component that brings precision, reliability, and easy serviceability to your hot tub plumbing. Designed for top-suction and top-discharge setups, this complete wet end fits the most common spa configurations and revives performance without replacing your entire pump.

• Complete wet end assembly — includes volute, seal, impeller, wear ring, suction cover, suction cover o-ring, drain plug, drain plug o-ring, and suction cover screws. Everything you need for a clean, ready-to-run rebuild.
• Top suction and top discharge configuration improves priming reliability and consistent flow in spa environments where space and piping layouts vary.
• 1-1/2" MBT connections on both suction and discharge with a 2-7/16" outer diameter, delivering a secure, leak-resistant fit for standard spa plumbing.
• 48 frame, 1.0 HP compatibility aligns with 48Y frame thru-bolt motors. Motor and unions are sold separately, offering flexible drive options (single or dual speed).
• Clear orientation details — drain plug located at 6 o’clock for straightforward maintenance and service.

The FMVP wet end is built for durability, intuitive service, and dependable performance — exactly what spa owners expect when they reach for a replacement part.
