Description

The Simpson 95404 is a 525-gallon dual-axle mobile water trailer equipped with a CRX210 gas engine and a 2-inch semi-trash pump delivering a 158 GPM flow rate for heavy-duty site maintenance. This DOT-certified over-the-road transport vessel utilizes a 9,000 lb axle rating and 16-inch premium tires to haul high-capacity liquid loads safely at highway speeds and across unpaved terrain. Outfitted with a low-oil shutdown sensor and a removable height-adjustable fill tube, this industrial mobile distribution platform resolves water-access issues and dust mitigation constraints during remote commercial contracting, road construction, and municipal cleaning tasks.

Best Used For:

  • Jobsite Dust Suppression: Spraying down high-traffic grading zones, soil pathways, and open excavation fields to manage structural particulate pollution.
  • Commercial Surface Washing: Feeding high-volume supply water cleanly to commercial power washing equipment for parking lot and masonry masonry cleaning.
  • Remote Landscape Irrigation: Supplying uniform, off-grid water transport to establish root growth on new highway sodding and rural agricultural plantings.

Key Performance & Safety Features

  • High-Volume Debris Management: Integrated 2-inch industrial semi-trash pump draws and processes debris-laden water at 158 GPM without line blockages.
  • CRX210 Thermal Safeguards: Embedded low-oil sensor shutdown stops the internal combustion motor instantly if lubrication drops below safe operation levels.
  • DOT-Certified Road Security: Fully compliant chassis build features synchronized weight balancing, structural lighting, and dual axles for legal highway travel.
  • Adjustable Overhead Clearance: Removable top fill tube adjusts structural height profiles between 77 inches and 85 inches to pass into lower garage layouts.
  • Heavy-Gauge Frame Platform: Reinforced steel transport chassis platform handles the 7,000 lb loaded fluid stress without cross-member bowing or flex fatigue.
