Stainless steel 4 5/8 in impeller

This Dayton PPL2207SG impeller is a stainless steel component built for straight centrifugal pumps. It serves maintenance teams and facility engineers who need a direct replacement for worn or damaged rotors in compatible Dayton pump models. The semi-open design suits liquids that may contain light solids or debris.

Corrosion-resistant construction

Stainless steel material resists rust and chemical attack in water, coolant or mild chemical service. The semi-open vane profile reduces clogging risk while maintaining steady hydraulic performance. No moving seals or bearings are included, so operating noise and power draw remain dictated by the host pump and motor.

Fits Dayton 2ZWX1A, 2ZWX2B, 2ZWZ5 pumps

The impeller matches Grainger part numbers 2ZWX1, 2ZWX2 and 2ZWZ5, allowing quick identification during service. It installs onto the existing pump shaft, freeing the mechanic from sourcing a complete pump assembly. Verify shaft diameter and keyway before fitting.

Questions about this item

How is the 4 5/8 in stainless-steel semi-open impeller installed on the pump shaft, and what step is often missed?

Slide the impeller onto the shaft, align the keyway with the shaft key, then tighten the lock-nut to the specified torque; the step most often missed is confirming the key is fully seated before final tightening.

What maintenance or replacement will the stainless-steel semi-open impeller need over its service life?

Inspect the vanes and hub for erosion, corrosion or cavitation damage at each scheduled pump overhaul; replace the impeller if vane thickness falls below the manufacturer’s minimum or if the hub shows cracking.

Which operational limit appears first when the pump runs continuously at high flow?

The semi-open design reaches its NPSH margin limit first; sustained operation beyond the published NPSH required causes cavitation that erodes the vane leading edges and reduces head.
