Honda 78107-yg3-750 Volute Case

Product Description

The HONDA 78107-yg3-750 is a volute case used in Honda water pump assemblies. The volute case forms the spiral-shaped housing that surrounds the impeller, converting the kinetic energy of the spinning impeller into pressure and directing water flow toward the discharge outlet. This is an OEM-specified replacement component installed by pump service technicians and small-engine mechanics working on Honda-branded water pump equipment.

The volute case is a core structural component in centrifugal water pump assemblies. It is typically found in residential and light commercial applications where Honda water pumps are used for irrigation, dewatering, or water transfer. Replacement is most commonly required after physical damage, cracking, or wear that compromises the pump's ability to maintain prime and pressure.
