4540 Fluid Section

Hydra Part 2401635A Fluid Section Assembly is a complete pump manifold assembly designed for compatible Hydra pressure washers.

It contains the internal pumping components responsible for drawing in water, pressurizing it, and delivering high-pressure output through the system. This includes the plungers, seals, valves, and internal fluid passages that work together to maintain proper pump function.

When the fluid section becomes worn, cracked, or leaking, it can cause pressure loss, bypass issues, or reduced cleaning performance. Replacing the complete assembly restores proper pressure, consistent flow, and reliable operation.
