PSH - FDN Series Impeller with Cataphoresis Coating (FDN-131) - 2292912

PSH – FDN Series Impeller with Cataphoresis Coating (FDN-131)

This is a genuine PSH replacement impeller for the FDN pump series (DN-1500 / DN-3000), finished with a cataphoresis (e-coat) treatment that applies a uniform, electrically bonded protective layer over the entire metal surface. The impeller is the core hydraulic component responsible for generating water flow through the pump, and keeping it in top condition is essential to maintaining filtration performance.

Cataphoresis Coating

Cataphoresis is an electrocoating process that deposits a uniform corrosion-resistant paint layer across all surfaces of the impeller — including edges, internal cavities, and complex curved geometry. This treatment significantly enhances resistance to corrosion compared to uncoated metal impellers, making this component well-suited to pools using salt chlorinators or other aggressive water chemistries.

Compatibility

This impeller is designed exclusively for PSH FDN series pumps, covering the DN-1500 and DN-3000 families. These are high-flow pumps built for public swimming pools, competition pools, and demanding commercial installations. Always cross-reference the exploded-view diagram (position 55) and your pump’s model number before ordering to confirm fitment.

Installation

Replacing a pump impeller requires draining and disassembling the pump, and correct reassembly is critical to performance and seal integrity. Installation by a qualified pool technician or engineer is strongly recommended. Using a genuine PSH impeller ensures dimensional accuracy and preserves the pump’s original hydraulic efficiency.
