Wacker Neuson 5000211358 Water Pump Complete

The Wacker Neuson is a genuine OEM Water Pump Complete designed for the CRT48-35L ride-on concrete trowel series, the DPU 130Le reversible vibratory plate compactor, and the PT6LT and PT6LS large-discharge trash pump series. As a factory-sourced component, the meets Wacker Neuson's original engineering standards, ensuring correct flow rates, port dimensions, and drive compatibility across all covered models. This pump assembly is confirmed to fit both standard and PS configurations of the CRT48-35L, as well as the T4-compliant PT6LT pump with trailer, covering a broad range of jobsite applications. When a water pump fails, coolant or fluid circulation stops — putting the engine at immediate risk of overheating — making prompt replacement with the correct part critical.

Key Features

• OEM-Matched Flow and Pressure Spec — Sourced directly from Wacker Neuson, this complete pump assembly is manufactured to the exact impeller, seal, and housing tolerances specified for each covered machine, ensuring consistent fluid delivery under load.
• Drop-In Assembly Replacement — Supplied as a complete unit with all internal components pre-assembled, so installation directly replaces the failed assembly without partial component sourcing or additional sub-assembly work.
• Broad Cross-Series Fitment — A single part number covers the CRT48-35L ride-on trowel (including PS and EU variants), DPU 130Le reversible plate compactor, and PT6LT and PT6LS large-volume trash pumps, making it a practical stock part for mixed fleets.
• Protects Engine from Thermal Overload — A functioning water pump maintains continuous coolant circulation through the engine. A worn or failing pump causes coolant flow to drop, leading to rapid overheating and potential engine seizure in high-demand applications.
• Cooling System Integrity — Correct seal material and housing fit prevent coolant leaks at the pump interface, maintaining system pressure and keeping the cooling circuit operating as designed across variable ambient temperatures.

A water pump circulates coolant through the engine's cooling system, drawing heat away from the engine block and cylinder head and transferring it to the radiator for dissipation. Without adequate coolant flow, engine temperatures rise rapidly, causing premature wear, seal failure, and in severe cases, catastrophic engine damage. On equipment like the CRT48-35L trowel and PT6LT trash pump — machines that often run at sustained high loads — a properly functioning water pump is essential to keeping the engine within its safe operating temperature range. When the pump impeller wears, seals crack, or the housing develops a leak, coolant loss and overheating follow quickly, making timely replacement with the correct complete assembly the most efficient service path.
