The Wacker Neuson is a genuine OEM M8 X 25 Bolt designed for PS4-series submersible pumps, including the PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF models. As a factory-sourced fastener, it meets the exact thread pitch, grade, and dimensional tolerances specified for these pumps, ensuring a secure and properly torqued connection. This bolt is used across a wide range of PS4 configurations — covering high-head and high-output variants in 50 Hz and 60 Hz ratings from 220 V through 575 V — as well as PSC4 three-phase submersible pump models. Verify your pump model number before ordering to confirm compatibility.
Key Features
- Genuine OEM Thread Specification — Sourced directly from Wacker Neuson, this M8 X 25 Bolt meets the exact thread class and tensile grade required for structural fastening on PS4 submersible pump assemblies.
- Direct-Fit Replacement — Matches the original bolt in length, head type, and thread form so it seats and torques correctly without modification to the pump housing or mating components.
- Broad PS4 Series Coverage — Compatible with PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF pumps across multiple voltage configurations, plus PSC42203 and PSC43703 three-phase models.
- Structural Integrity of the Pump Assembly — A properly spec'd fastener keeps pump housing sections and motor components aligned and sealed under continuous submersed operating loads; an incorrect or worn bolt risks loosening, misalignment, or water ingress.
- Critical Fastener for Electrical Safety — Fasteners in submersible pump assemblies secure motor housings and grounding connections; using the correct OEM-spec bolt supports the mechanical integrity needed for safe submerged electrical operation.
An M8 X 25 bolt is a metric fastener with an 8 mm thread diameter and a 25 mm shank length, used to clamp and secure pump housing sections, motor mounts, or ancillary brackets within the pump assembly. In submersible pump applications, fasteners like this one must maintain clamping force under continuous immersion, vibration from the motor, and the pressure of pumped fluid — conditions that accelerate corrosion and fatigue on non-spec hardware. When this bolt loosens or fails, it can allow housing sections to shift, compromising seals, motor alignment, and the overall watertight integrity of the pump.
