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
