Multiquip Diesel-Powered Trash Pumps

Description

Multiquip Diesel Trash Pumps — Heavy-Duty Flow for the Roughest Water

When the jobsite hands you rocks, sludge, and rebar-laden runoff, a diesel trash pump from Multiquip keeps the water moving instead of clogging or losing prime. These self-priming, wet-prime units’ pair rugged, open-impeller hydraulics with Tier 4 Final Kubota or Hatz diesels, giving contractors a transport-ready powerhouse that runs easily on a single tank, and shrugs off solids up to 3 inches. From the 475 GPM QP4TK to the flagship MQ600H that blasts 1,600 GPM at 150 feet of head, every diesel trash pump in the lineup is engineered to tame the dirtiest, most abrasive water on earth.

Why Choose a Diesel Trash Pump Instead of Gas or Electric?

• Torque at Low RPM — Diesel engines deliver high shaft power without screaming revs, extending seal life in the centrifugal water pump housing.
• Fuel-Stretching Efficiency — A 28-gallon trailer tank on the QP4TKT28 powers the 4-inch model through multi-shift bypass jobs.
• Safety & Compliance — Diesel’s high flash points make it the go-to choice when a dirty water pump must run near welding, hot mix, or petro-chemical sites.

All models share heavy aluminum pump ends, ductile-iron volutes, and abrasion-resistant wear plates—components proven to outlast ordinary centrifugal water pump sets when grit hits the impeller.

Built-In Features That Pay Off

• Fast Wet-Prime System
  Vacuum assist evacuates air quickly; the diesel trash pump is moving water in seconds, not minutes.
• Oversize Clean-Out Door
  Remove fist-size debris without pulling suction hose, a task that stalls lesser trash pump designs for an hour.
• Auto-Start & Float Switch Ready
  Factory wiring makes it simple to add level controls for unattended sewer bypass or quarry dewatering.
• DOT-Approved Trailers
  Multiquip’s heavy-channel frames roll at highway speed, turning each unit into a mobile dirty water pump that arrives ready to run.

Real-World Applications

1. Sewer & Storm-Bypass Jobs — Keep lines live while crews repair mains, the open impeller swallow’s rags better than any standard centrifugal water pump.
2. Flood-Control & Emergency Response — Tow a 6-inch diesel trash pump to the scene and drop suction in minutes, moving 96,000 gallons an hour.
3. Mining & Quarry Pits — Continuous operation in slurry thanks to silicon-carbide seals and oil-bath bearings that a light-duty dirty water pump can’t match.
4. Large-Scale Construction Dewatering — Maintain excavation depth during sheet-pile driving or mat pours without babysitting multiple smaller pumps.

Low-Maintenance, High-Uptime Engineering

Multiquip designed every diesel trash pump around fast daily checks: single-side service doors, spin-on filters, and color-coded drains put oil, coolant, and impeller inspection points within arm’s reach. A heavy, locking hood shields electronics from vandalism, while vibration isolators protect both engine and centrifugal water pump bearings during trailer travel.
