Engine & Runtime Advantage
Powered by a 9.5 HP Kubota diesel engine, the QP4TKT28 is built for extended-duty cycles and fuel efficiency. The integrated 28-gallon fuel cell allows this high-flow dewatering pump to operate for up to 44 hours on a single tank, reducing refueling interruptions during long or overnight pumping operations.
The engine is EPA/CARB certified and equipped with electric start for fast, reliable startup in the field.
Pump Construction & Durability
This 4 inch centrifugal trash pump is engineered for abrasive, debris-laden water commonly encountered on construction and emergency job sites.
- Rugged aluminum pump casings for fast priming
- #45 ductile iron impeller and volute for abrasion resistance
- Silicon / carbon mechanical seal for long service life
- Large clean-out chamber for quick debris removal
- Shock-mounted pump assembly to reduce vibration and wear
These components support long-term, continuous dewatering performance under harsh conditions.
Trailer & Mobility System
The QP4TKT28 is mounted on a Multiquip DOT/NHTSA-approved trailer, manufactured in the U.S.A., allowing this trailer mounted trash pump to be:
- Towed directly to the job site
- Rapidly deployed without lifting equipment
- Stabilized during operation
An industrial lifting bale is included for handling during transport or positioning.

What This Trailer-Mounted Trash Pump Is Used For
The QP4TKT28 is selected for large-scale dewatering applications and continuous water movement, especially when pumping must continue for extended periods without refueling.
- Construction excavations and large site dewatering
- Emergency flood response and stormwater removal
- Sewage bypass pumping (within rated solids limits)
- Water transfer and industrial pumping
- Barge and marine cleaning
This 4 inch diesel trash pump is designed for continuous-duty operation, not intermittent or light-duty use.
Application Limits (Important)
This 4 inch trailer mounted trash pump is designed for water containing debris and solids, not for:
- Dry-run operation
- Thick sludge or viscous slurry
- Chemical transfer
- Solids larger than 2″ diameter
Proper application is required to maintain performance and service life.
