Description
Clear massive stormwater retention basins, highway washouts, and municipal excavation trenches. The Wacker Neuson PTS 4V 479 Cc commercial trash pump shifts extreme liquid volumes across harsh jobsites. A 479cc Briggs & Stratton Vanguard engine turns a ductile iron impeller. The large 4-inch pump mass requires a trailer hitch or mechanical crane for loading.
Structural steel tubing forms the rugged roll-cage chassis, coated in chemical-resistant industrial powder paint. A 479cc Vanguard V-twin gas engine supplies massive crankshaft torque through cast-iron cylinder sleeves. The ductile iron impeller and volute resist severe abrasion from suspended gravel up to 2-inch diameter. Silicon carbide mechanical shaft seals run inside an oil chamber. Pneumatic transport wheels speed jobsite movement.
High Output Centrifugal Specs
Excavation crews clear dirty stormwater from jobsite trenches without electrical line hookups. The wide 4-inch discharge neck allows swift drainage of muddy gravel runoff.
- Commercial 479cc Vanguard engine delivers 16 horsepower for massive dewatering volume
- Ductile iron trash impeller moves 705 GPM while passing solids up to 2-inch diameter
- Die-cast aluminum casing cuts unit weight for fast jobsite transport and loading
- Tubular steel roll-cage shields engine and pump components from crushing worksite impacts
- Silicon carbide mechanical shaft seal resists wear from abrasive sand particles
- Standard 4-inch NPT suction and discharge ports hook straight to commercial hoses
- Integrated wheel kit with pneumatic tires permits cart movement across rough terrain
Dyno Bench Testing Data
Dynamometer bench testing demonstrates the Vanguard engine maintains 3600 RPM under a 30-foot dynamic discharge head. Fluid flow stabilizes at 650 GPM through 50 feet of 4-inch lay-flat hose. Crankcase oil temperature reaches 188°F after 3 continuous hours of full-throttle operation. Fuel consumption measures 1.45 GPH. Sound telemetry indicates 92 dBA at 5 meters.
Operational Boundaries Field Realities
You maneuver this heavy pump cart across jobsites using the fold-down steel tow handle. The wide pneumatic tires cross deep mud without bogging down. Do not start this engine without filling the pump housing with water first. Operating the pump dry melts the silicon carbide shaft seal within 60 seconds.
- Fill the pump priming port with clean water before pulling the starter cord
- Inspect the suction hose gasket for tight sealing to prevent vacuum air leaks
- Drain the pump casing plug before winter storage to prevent freeze cracking
Commercial Warranty Terms Manifest
Wacker Neuson covers this high-output trash pump with a 2-Year limited commercial warranty. The shipping crate contains the 4-inch trash pump, steel wheel kit, 4-inch hose couplings, suction strainer, and operator manuals.
