The Wacker Neuson Hose Coupling is a genuine OEM component designed for the PS3 and PS4 series submersible pumps, including the PS3 5503, PS4 5503, PS4 7503HH, PS4 7503HF, PS4 11003HH, and PS4 11003HF models across 220V, 440V, and 575V configurations. As a direct OEM part, the is manufactured to the exact material and dimensional specifications of the original, ensuring a secure, leak-free connection at the pump discharge. Covering the full range of 100mm/4-inch PS-series submersible pump variants, this coupling delivers the correct fit across a wide spread of voltage ratings and horsepower classes without guesswork.
Key Features
- Genuine OEM Construction — Manufactured to original material and dimensional tolerances, ensuring the coupling seats and seals correctly at the pump discharge port without distortion or leakage under pressure.
- Direct-Fit Discharge Connection — Designed to connect directly to the pump outlet, matching the original thread profile and port diameter for a secure, tool-assisted installation with no adapters needed.
- Broad PS-Series Compatibility — Fits PS3 5503, PS4 5503, PS4 7503HH, PS4 7503HF, PS4 11003HH, and PS4 11003HF submersible pumps across 220V, 440V, and 575V ratings.
- Sustained Flow Integrity — A correctly seated hose coupling maintains full discharge pressure and flow rate; a cracked or failed coupling allows bypass leakage that starves the discharge line and strains the pump motor.
- Multi-Voltage Model Coverage — One part number spans the complete voltage range of the PS3 and PS4 pump families, simplifying parts sourcing across mixed fleets.
The hose coupling connects the submersible pump's discharge outlet to the attached discharge hose or piping, forming the primary sealed junction through which all pumped water exits the unit. It must maintain a pressure-tight connection during continuous operation — a worn, cracked, or improperly fitted coupling will allow water to bypass the discharge line, reducing output flow and placing additional load on the pump motor. On high-output models like the PS4 11003HH and PS4 11003HF, where flow volumes and pressures are significant, a compromised coupling can accelerate seal wear elsewhere in the pump assembly and result in unplanned service intervals.
