Fluidra - Motor Tie Bolts for Sena SS Pump (½–1 HP) - 4405010427

Fluidra – Motor Tie Bolts for Sena SS Pump (½–1 HP)

These are the genuine Fluidra replacement motor tie bolts (through-bolts) designed to clamp and secure the motor end covers and fasten the motor assembly to the pump body on the AstralPool Sena SS self-priming pool pump. They are a critical structural fastener, ensuring the motor remains rigidly aligned with the pump hydraulic end during operation. This set covers the ½ HP to 1 HP single-phase variants of the Sena SS range.

Compatibility

These motor tie bolts are compatible with the Fluidra AstralPool Sena SS self-priming pool pump range, specifically the ½ HP and 1 HP single-phase (50 Hz) models. Always verify your pump’s model reference before ordering to ensure the correct hardware fit. They are not intended for three-phase or higher-horsepower variants of the Sena SS series.

Why Genuine Matters

Using genuine Fluidra hardware ensures the correct thread specification, length, and tensile strength for reliable long-term clamping force. Substandard or incorrect tie bolts can lead to motor misalignment, vibration, premature wear on the mechanical seal, or water ingress — all of which can cause costly pump failure. Genuine Fluidra parts are manufactured to the exact tolerances of the original assembly.

Installation

When fitting replacement motor tie bolts, ensure all bolts are finger-tightened before final torquing, and tighten in a cross-pattern to achieve even clamping force across the motor end cover. It is recommended to lightly grease the bolt threads with a non-petroleum-based grease prior to assembly. If you are not confident working on pool pump motors, installation by a qualified pool technician is advised.
