Wacker Neuson 5100026515 High Pressure Pump

The Wacker Neuson 5100026515 High Pressure Pump is a genuine OEM component designed for the CRT48-37V series ride-on concrete trowels, including the standard CRT48-37V, the Power Steer variant CRT48-37V-PS, and the CRT48-37V EU configuration. As a direct Wacker Neuson OEM part, the 5100026515 is manufactured to the exact specifications required for proper hydraulic system function in these machines. Sourcing a genuine replacement ensures the pump delivers the correct flow and pressure characteristics the CRT48-37V hydraulic circuit depends on. When the high pressure pump is worn or failing, operators will notice degraded rotor or blade pitch control, making prompt replacement essential to maintaining consistent finish quality on the slab.

Key Features

• Genuine OEM Hydraulic Output Spec — manufactured to the exact pressure and flow ratings required by the CRT48-37V hydraulic system, ensuring the circuit operates within its designed parameters.
• Direct-Fit Replacement — mounts and connects to the existing hydraulic lines and drive interface on the CRT48-37V without alteration, simplifying the swap during scheduled service or emergency repair.
• Broad CRT48-37V Coverage — confirmed fitment across the CRT48-37V, CRT48-37V-PS Power Steer, and CRT48-37V EU models, covering the full current production range of this trowel series.
• Consistent Blade Pitch and Rotor Control — a correctly functioning high pressure pump maintains the hydraulic pressure needed to deliver smooth, responsive pitch adjustment across all rotor arms, directly affecting surface finish quality.
• Hydraulic System Safety — running a worn or underperforming pump can cause pressure spikes or drops that stress seals, hoses, and control valves throughout the hydraulic circuit; replacing with a genuine OEM pump protects the broader system.

The high pressure pump is the heart of the hydraulic system on a ride-on concrete trowel. It generates the pressurized fluid flow that powers rotor pitch control, allowing the operator to adjust blade angle and finishing pressure across the full working width of the machine. When the pump begins to wear, pressure output drops, leading to sluggish or uneven blade response and compromised surface finish. A failed pump can bring the machine to a complete stop mid-pour — a costly outcome when working to tight concrete finishing windows.
