Versatile Fluid Transfer for Demanding Industrial Applications
Mody Pumps’ MDP Series is an air operated diaphragm pump range developed for transferring a wide variety of fluids across industrial applications. The pumps use compressed air to drive the diaphragms, allowing them to handle clean liquids, viscous media, abrasive fluids, and liquids containing suspended solids without conventional rotating pump components.
The MDP Series is available in ½", 1", 1.5", 2", and 3" sizes and can operate either submerged or with flooded suction. As an air operated double diaphragm pump, it also offers variable flow control and can operate at pressures up to 99 psi, making it suitable for a broad range of process and transfer duties.
A key advantage of the MDP design is dry-start self-priming up to 6 metres without a foot valve. With no shaft seals or gland packing, the self priming diaphragm pump minimizes leakage points, while low internal fluid velocity helps reduce wear during operation.
Explore air operated diaphragm pumps for reliable transfer of clean, viscous, abrasive and solids-laden fluids in industrial applications. Dutco supplies MDP Series air operated diaphragm pump solutions for projects requiring flexible, portable, and reliable fluid handling across demanding operating environments.
Reliable Pumping Across Variable Fluid Conditions
- Wide Fluid Compatibility – Handles a broad range of fluids, including media with high solids content.
- Variable Flow Operation – Flow can be adjusted according to process requirements.
- Up to 99 psi Pressure – Supports demanding transfer duties with operating pressure up to 99 psi.
- Dry-Start Self-Priming – The pneumatic diaphragm pump can self-prime from a dry start up to 6 metres without a foot valve.
- Submerged Operation – Can operate submerged or with flooded suction.
- Low Internal Velocity – Reduced fluid velocity inside the pump helps minimize component wear.
Air-Powered Design for Safe & Low-Maintenance Operation
