AstralPool – Pump Housing for Colusa Pump

The genuine AstralPool pump housing is the main structural body of the Colusa self-priming pool pump, enclosing and protecting the internal hydraulic components — including the impeller, diffuser, and mechanical seal. It forms the watertight core that channels water efficiently through the pump, maintaining the hydraulic integrity that the Colusa range is known for.

Compatibility

This pump housing is designed exclusively for the AstralPool Colusa pump (parent SKU 70579) and corresponds to position 8 in the official Fluidra exploded-view diagram. The Colusa is a plastic self-priming pump available from ½ hp to 3 hp in single-phase and three-phase configurations. Always verify your pump’s SKU before ordering to ensure an exact fit.

Why Genuine Matters

As a direct Fluidra/AstralPool OEM part, this housing is precision-manufactured to the same tolerances as the original, ensuring a correct seal, proper alignment of rotating parts, and no compromise to the pump’s flow or noise performance. Aftermarket alternatives risk misalignment, leaks, and premature wear of the impeller and shaft.

Installation

Replacing the pump housing requires draining the pump, disconnecting pipework, and accessing the internal hydraulic assembly. Correct reassembly is critical to avoid leaks and ensure safe operation, so professional installation by a qualified pool technician is strongly recommended. Always refer to the official Fluidra exploded-view diagram (position 8) to confirm part orientation and fastener sequence.
