Description

Pentair CH-N2-1-1/2F power end sustains peak hydraulic output with upgraded impeller staging for elevated head pressures. Excels in pushing flow through restrictive spa jets, in-floor cleaning, and oversized filters while minimizing cavitation in hot Arizona climates. Quick motor swap restores full 2HP-class operation, maximizing turnover rates without hydraulic bottlenecks.

Pro Tip

Inspect motor shaft for wear before install—upgrade to 355035S 2HP 2-speed motor (similar to prior 355034S) for matched performance.
