The Honda 78107-YE9-505 Volute Case is a genuine OEM replacement built for the WX10 water pump. As a direct Honda OEM component, this part is manufactured to the same specifications as the original, ensuring a correct fit and proper hydraulic performance. This Volute Case is designed specifically for the WX10 lightweight water pump, so buyers should confirm their unit's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM Construction — manufactured by Honda to match the original Volute Case exactly, preserving the pump's designed flow path and pressure output
- Correct Hydraulic Geometry — the volute profile is shaped to convert impeller velocity into pressure efficiently; a cracked or damaged case causes pressure loss and reduced flow output
- WX10 Water Pump Fitment — sourced specifically for the WX10, Honda's ultra-compact lightweight pump; verify your serial number against the fitment table to confirm the correct case for your unit
The volute case is the spiral-shaped housing that surrounds the impeller in a centrifugal water pump. As the impeller spins, water is flung outward by centrifugal force and collected by the volute's gradually widening channel, which converts that velocity into usable pressure at the discharge port. When the volute case cracks, chips, or wears, the seal between the impeller and housing is compromised, resulting in a drop in flow rate and discharge pressure that no amount of engine output can compensate for.
