Product Description
Jobsite-Ready Diaphragm Pump for Muddy Water, Sludge & High-Solids Applications
The Multiquip MQD2HA is a 2-inch gas-powered diaphragm pump designed to move muddy water, sludge, and debris-laden fluids in demanding construction and utility environments. Using a positive displacement diaphragm design, the MQD2HA delivers consistent pumping performance where centrifugal trash pumps may clog or lose efficiency.
Powered by a Honda GX120 3.5 HP gasoline engine, this pump provides dependable operation for dewatering, utility work, and general jobsite pumping applications that involve high solids content and intermittent flow conditions.

Applications for the Multiquip MQD2HA
The Multiquip MQD2HA is purpose-built for applications where mud, sludge, and solids-laden water would challenge conventional pumps.
Typical applications include:
Construction site dewatering
Utility and municipal work
Muddy water and high-solids pumping
Sludge and debris-laden fluid transfer
Jobsite and rental fleet applications
Its diaphragm design makes it especially effective in environments with variable water levels and heavy solids content.
Why Choose the Multiquip MQD2HA?
Positive Displacement Diaphragm Performance
The MQD2HA uses a reciprocating diaphragm pumping action to move high-viscosity liquids and debris-laden fluids efficiently. This design allows the pump to maintain performance in conditions that often reduce the effectiveness of centrifugal trash pumps.
Handles High Solids Content
Capable of passing solids up to 1-5/8 inches, the MQD2HA is well suited for muddy water, sludge, and debris that can clog standard pumps.
Reliable Honda GX120 Engine
The Honda GX120 engine provides reliable starting, consistent power, and easy serviceability making it a familiar and trusted choice for contractors and rental fleets.
Enclosed Gear Drive for Durability
An oil-bath lubricated, enclosed gear system helps reduce wear and supports long service life in demanding jobsite conditions.
Built for Jobsite Mobility
The integrated wheel kit allows the MQD2HA to be moved easily across uneven terrain, reinforcing its role as a practical, jobsite-ready diaphragm pump.
What This Diaphragm Pump Is Not Intended For
For proper application and performance:
Not designed for clean-water or irrigation use
Not a replacement for high-flow centrifugal pumps
Not intended for continuous high-pressure deadheading

Frequently Asked Questions
What is the Multiquip QP3TH used for?
The Multiquip QP3TH is used for construction site dewatering, water transfer,
flood cleanup, trench work, and utility applications where water contains
debris or solids.
Can the QP3TH handle solids?
Yes. The QP3TH can handle solids up to 1.5 inches in diameter, making it
suitable for dirty, debris-filled water commonly found on construction and
utility job sites.
Is the QP3TH portable?
Yes. The pump features a compact tubular steel frame and manageable operating
weight, allowing it to be easily transported between job sites.
What makes this different from a water pump?
Trash pumps are designed to move dirty water containing solids and debris,
while standard water pumps are intended for clean water only. Trash pumps
feature heavy-duty impellers and larger internal clearances to prevent clogging.
Is the Honda engine reliable?
Yes. The Honda GX240 engine is well known for reliability, fuel efficiency,
and long service life. It also includes low-oil shutdown protection to help
prevent engine damage.
What is the difference between a centrifugal pump and a trash pump?
A trash pump is designed to move dirty water containing sand, rocks, leaves,
or debris using a heavy-duty impeller and large internal clearances. A standard
centrifugal pump is intended for clean or lightly contaminated water and can
clog or wear quickly when exposed to debris.
Can I run a trash pump without water?
No. Trash pumps must be primed with water before operation. Running a trash
pump dry can damage the mechanical seal and internal components.
How far can a trash pump pull water?
Most trash pumps, including the Multiquip QP3TH, can lift water up to 25 feet
vertically (maximum suction lift). Actual performance depends on hose length,
elevation, and water conditions.
How is the QP3TH shipped and what should I expect?
The QP3TH ships fully assembled and ready for use. Due to its size and weight,
it is typically shipped via freight. Tracking information is provided after
shipment, and delivery coordination assistance is available if needed.
