Zodiac – Backplate kit FHP (with hardware, O-ring and mechanical seal) – R0770608

The Zodiac R0770608 is an original replacement backplate kit designed for Zodiac FHP (Flo-Master HP) series pool pumps. This kit contains everything required to properly seal and secure the rear housing of the pump, including the backplate itself, all necessary mounting hardware, a precision O-ring, and a mechanical seal. Sourced directly from Zodiac, this is a genuine OEM spare part engineered to exact factory tolerances, ensuring a reliable and leak-free repair of your pool pump.

The backplate forms the rear closure of the pump wet end, creating the sealed chamber that houses the impeller and directs water flow through the pump volute. Over time, mechanical seals and O-rings deteriorate due to continuous exposure to pool water, chemicals, and pressure cycling, leading to leaks or loss of pump performance. Replacing these components with the complete Zodiac R0770608 kit restores the pump to original operating condition and prevents more serious damage to the motor bearings caused by water ingress.

Technical characteristics and kit contents

The R0770608 kit is supplied as a complete assembly package, which significantly simplifies the service process. Rather than sourcing each component individually, this single kit provides the backplate, the mechanical shaft seal, the sealing O-ring, and all associated hardware such as bolts or fasteners. The mechanical seal is the critical dynamic sealing element that prevents water from travelling along the pump shaft into the motor housing. The O-ring provides the static seal between the backplate and the pump body. Using matched, genuine Zodiac components ensures dimensional accuracy and chemical compatibility with standard pool water treatment products including chlorine-based sanitisers.

This part is listed and referenced across multiple Zodiac product catalogues including the 2018 and 2020 Zodiac Pool Care Equipment catalogues, confirming its long-standing availability and ongoing applicability within the Zodiac FHP pump range.

Suitability and application

This backplate kit is intended for use with Zodiac FHP series pool pumps. It is the correct part for pool owners, service technicians, and pool maintenance professionals who need to carry out wet end servicing or seal replacement on a compatible Zodiac FHP pump. It is suitable for standard in-ground and above-ground pool installations where a Zodiac FHP pump is fitted as the primary circulation pump. If your pump is showing signs of water leakage around the rear housing, seal wear, or reduced flow due to internal wear, this kit provides a cost-effective and straightforward solution compared to full pump replacement.
