The QP3TK Diesel Trash Pump is a heavy‑duty 3" centrifugal trash pump engineered by Multiquip for tough dewatering applications such as excavations, floodwater removal, sewage by‑pass, barge cleaning, and general water transfer. Powered by a 6.0 HP Kubota OC60‑E4 diesel engine with electric start, it delivers up to 325 gallons per minute (GPM), 85 ft max head, and can pass solids up to 1.5" in diameter.

QP3TK Diesel Trash Pump – Core Performance

The QP3TK Diesel Trash Pump is a 3" suction/3" discharge unit designed as a dependable industrial trash pump for professional contractors, municipalities, and industrial users.

Key hydraulic performance data:

• Suction x discharge: 3" × 3" (76 × 76 mm).

• Maximum water capacity: 325 GPM (about 1,450 L/min).

• Maximum head: 85 ft (about 27 m).

• Maximum lift: 25 ft (7.6 m) from the water surface to the pump.

• Maximum pressure: about 37.7 psi (268 kPa).

• Maximum solid intake: 1.5" (37 mm) spherical solids.

These specs make the QP3TK Diesel Trash Pump an excellent choice for pumping dirty water containing mud, stones, and debris typical of construction sites, storm events, and sewage by‑pass operations.

Kubota Diesel Power and Electric Start

A major advantage of the QP3TK Diesel Trash Pump is its compact Kubota diesel powerplant.

Engine details:

• Engine model: Kubota OC60‑E4 diesel.

• Power output: 6.0 HP (4.5 kW class).

• Emissions: EPA Tier 4 Final and CARB compliant for use in regulated regions.

• Starting system: Electric start for convenience; many packages also include recoil start backup.

• Fuel tank capacity: 0.95 gallons (3.5 L).

The combination of diesel torque, low fuel consumption, and electric start makes this pump ideal for long‑duration dewatering jobs where reliability and run time matter more than ultra‑light weight.

Heavy-Duty Pump End and Fast Priming Design

The QP3TK features Multiquip’s signature die‑cast aluminum pump casing with heavy‑duty internal components designed to promote fast priming and long life.

Pump‑end construction:

• Pump body: Die‑cast lightweight aluminum casings engineered for the fastest priming times and ease of handling.

• Impeller: #45 ductile iron, special‑balanced multi‑vane open impeller for moving heavy debris while resisting abrasion.

• Volute: #45 ductile iron volute, double‑passage design to improve priming speed, flow efficiency, and reduce clogging.

• Mechanical seal: Silicon/carbon seal with 303 stainless steel components, built to handle abrasive particles, high temperatures, and continuous duty.

The pump is designed specifically as a trash pump, not a clear‑water pump, meaning it can reliably handle water laden with sand, mud, and 1.5" solids without rapid wear or frequent clogs.

Dual 3" Discharge Ports and Application Flexibility

A standout feature of the QP3TK Diesel Trash Pump is its dual discharge design.

• Dual 3" discharge ports on the left and right sides give you flexibility in hose routing, allowing better positioning on cramped sites or on barges.

• This design can improve workflow when connecting multiple discharge lines or when reconfiguring the pump position between tasks.

For contractors and municipalities, this flexibility helps adapt the same pump to a variety of field setups, from trench dewatering to pond draining to temporary bypass systems.

Frame, Shock Mounting, and Durability

The QP3TK is built on a rugged construction‑grade frame with vibration isolation features.

• Frame: 1" tubular steel frame fully enclosing the pump and engine, providing protection and easy lifting/strapping points.

• Shock‑mount system: Engine and pump assembly are shock mounted to the frame to dampen operating harmonics, reducing vibration transferred to the frame and extending component life.

• Optional wheel kit: UWKA bolt‑on wheel kit is available to convert the base frame into a two‑wheel portable cart for easier movement around jobsites.

This robust frame and shock isolation allow the pump to withstand harsh construction, industrial, and marine environments while protecting the engine and pump end from impacts.

Dimensions, Weight, and Portability

Despite its industrial build, the QP3TK remains relatively compact for a diesel 3" trash pump.

Key physical specs:

• Overall length: 27.0 in (686 mm).

• Overall width: 23.5 in (597 mm).

• Overall height: 24.0 in (610 mm).

• Operating weight: approx. 176 lb (80 kg).

The pump can be lifted by two people when needed or easily moved using the optional wheel kit on smooth surfaces. Its compact footprint makes it suitable for placement in trenches, inside plants, on barges, or on crowded urban jobsites.

Typical Uses and Ideal Applications

The QP3TK Diesel Trash Pump is marketed as the professional’s choice for the toughest dewatering tasks.

Typical applications include:

• Excavation and trench dewatering on construction sites.

• Flood water removal from basements, underpasses, and low‑lying areas.

• Sewage bypass operations (non‑corrosive, non‑flammable, pumpable sewage/effluent).

• Barge cleaning and marine work where diesel power is preferred.

• General water transfer from ponds, lagoons, and temporary storage tanks.

Because it can handle 1.5" solids and 325 GPM at up to 85 ft head, the QP3TK is ideal when you need both debris handling and decent total dynamic head over moderate hose runs.

Advantages of Diesel vs Gasoline in the QP3TK

Choosing the QP3TK Diesel Trash Pump over a similar gas model offers several advantages:

• Fuel efficiency: Diesel engines typically consume less fuel than comparable gasoline engines under similar load, beneficial on long‑running dewatering jobs.

• Safety: Diesel fuel has a higher flash point than gasoline, reducing fire risk in some industrial and marine environments.

• Durability: Kubota industrial diesels are known for long life and extended maintenance intervals when properly serviced.

• Regulatory compliance: EPA TIER 4 Final and CARB compliance allow use in emissions‑regulated states and municipal fleets.

These benefits make the QP3TK an attractive investment for contractors and rental houses focused on long‑term reliability and lower operating costs.

Maintenance and Service Considerations

The QP3TK Diesel Trash Pump is designed for straightforward routine maintenance:

• Large clean‑out chamber: The pump volute includes a large clean‑out cover so you can quickly remove accumulated debris or inspect the impeller without fully disassembling the pump.

• Mechanical seal: The silicon/carbon mechanical seal and stainless components are built for abrasive environments, but should still be inspected periodically, especially if pumping very dirty water or running dry.

• Engine service: Kubota OC60‑E4 diesel requires standard oil, filter, and fuel system maintenance following Kubota’s schedule to ensure long life and reliable electric starting.

• Frame and hardware: Regular checks of frame bolts, mounts, and shock isolators help maintain structural integrity under constant vibration.

Following the service guidelines in Multiquip’s manual and Kubota’s engine documentation will maximize uptime and pump life.
