Description
Flooded fields and retention ponds demand rapid water evacuation before soil structure collapses. The Honda WB Series 3 In general purpose pump moves clean and murky water at 290 GPM with 85 feet total head. Powered by a commercial Honda GX160 engine, it transfers high volumes. The cast-iron impeller clogs if debris chunks exceed 0.25 inches.
Honda houses the wet end inside an aluminum casing that dissipates engine heat and reduces transport weight. A four-vane cast-iron impeller mates to a cast-iron volute to resist erosion from suspended silt and small sand particles. A carbon-ceramic mechanical seal runs against an isolated rubber boot to stop water migration into the engine crankshaft seal. Rubber engine mounts dampen vibration against the black tubular steel cradle to reduce frame fatigue on hard concrete.
Field Hardware Performance Matrix
Agricultural drainage and construction dewatering demand high flow volume and fast prime recovery. This centrifugal transfer pump couples commercial gas power with rugged iron wear surfaces for reliable water relocation.
- Honda GX160 4.8 HP engine delivers consistent commercial power with an integrated low-oil alert shutdown system.
- 3-inch NPT suction and discharge ports accept standard high-volume contractor cam-lock hose connections.
- Cast-iron four-vane impeller delivers 290 GPM maximum flow for rapid pond and retention basin draining.
- Abrasion-resistant cast-iron volute liner protects the lightweight aluminum pump casing from high-velocity erosion.
- Full tubular steel roll cage shields the engine block and wet-end casing from jobsite impact hazards.
- Built-in check valve flapper holds water prime inside the housing to shorten re-priming time between runs.
- Commercial carbon-ceramic mechanical seal maintains water-tight shaft sealing under continuous 3600 RPM operation.
Dyno Load Realities Heat Data
Dyno test cycles at wide-open throttle with 3600 RPM show fuel consumption settling at 0.38 GPH under full flow resistance. Pumping against a 35-foot dynamic head produces 210 GPM while engine crankcase oil stabilizes at 222°F in an 88°F shop test cell. Volute casing surface temperature measures 86°F with constant fluid passage. Acoustic pressure reads 78 dBA at 23 feet distance. Suction prime time at 15 feet of vertical lift registers 80 seconds through standard 3-inch reinforced suction hose.
Field Service Application Limits
Weighing 57 pounds dry, this pump transports via the tubular frame by a single worker across level turf. Do not operate this unit to pump sewage, raw slurry, or solid rocks over 0.25 inches. Oversized solids wedge behind the impeller vanes, stall the engine, and shatter the cast-iron volute casing.
- Clean the suction hose strainer after every use to prevent grass and leaves from starving pump intake volume.
- Check engine oil level prior to each work shift and change SAE 10W-30 oil every 100 hours.
- Drain water from the volute casing through the lower plug before freezing winter weather sets in.
Commercial Warranty Package Inventory
Honda backs this WB30XT pump with a 3-Year commercial warranty covering both the pump wet end and the GX160 engine. The factory carton includes the pump unit, a commercial steel suction strainer, two 3-inch hose coupling nuts, two rubber sealing washers, three hose clamps, and a spark plug wrench.
