The Wacker Neuson Shim is a genuine OEM component designed for the PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF series submersible pumps. Sourced directly from Wacker Neuson, this shim is manufactured to the exact tolerances required for proper internal clearance and alignment within the pump assembly. It fits a broad range of PS4-series configurations spanning 220V, 400V, 440V, and 575V variants in both high-head and high-output configurations, as well as PSC42203 and PSC42303EX three-phase submersible pump models. If you are servicing or rebuilding a PS4-series submersible pump, verifying part number against your machine's serial number ensures you receive the correct shim thickness for your application.
Key Features
- OEM-Specified Thickness Tolerance — Manufactured to the exact dimensional spec required by Wacker Neuson, ensuring correct internal clearance without guesswork during reassembly.
- Direct Drop-In Fit — Seats in the same position as the original with no rework or machining to the pump housing or shaft assembly.
- Broad PS4-Series Coverage — Compatible with PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF models across multiple voltage configurations, plus PSC42203 and PSC42303EX three-phase units.
- Preserves Pump Efficiency — Correct shimming maintains proper impeller-to-housing clearance, which directly affects flow rate and motor load; an incorrect or worn shim leads to reduced output and premature wear.
- Genuine Wacker Neuson OEM Part — Carries the same part number used in Wacker Neuson's own service documentation, so you can cross-reference with confidence before ordering.
A shim is a precisely dimensioned spacer used inside the pump assembly to set and maintain correct clearances between rotating and stationary components — most commonly between the impeller and the pump casing or along the motor shaft stack. In a submersible pump, even a small deviation in this clearance affects hydraulic efficiency: too much gap reduces flow and pressure, while too little risks mechanical contact and accelerated wear on internal parts. When a shim is lost during service, deforms over time, or is replaced with an incorrect thickness, the pump will often show reduced output, increased current draw, or abnormal vibration, making it essential to reinstall the correct OEM-specified part during any rebuild or inspection service.
