Versa-Matic High Pressure AODD Pumps
Versa-Matic High Pressure AODD Pumps
Versa-Matic high pressure air-operated double diaphragm (AODD) pumps are designed for applications where discharge pressure above standard AODD pump capability is required. These metallic 2:1 high-pressure pumps can deliver discharge pressures up to 232 psi (16 bar), making them suitable for demanding fluid-transfer duties involving high head pressure, viscous fluids and long-distance pumping.
The range includes 1″ and 2″ high-pressure configurations with aluminum or stainless steel wetted materials. Their air-driven design retains common AODD advantages such as self-priming operation, safe deadheading and reliable restart on demand.
Choose a Versa-Matic High Pressure Pump
Versa-Matic E1-1″ High Pressure AODD Pump
Compact 1″ metallic 2:1 high-pressure AODD pump with flow rates up to 33 gpm (125 lpm) and discharge pressure capability up to 232 psi (16 bar).
Versa-Matic E2-2″ High Pressure AODD Pump
High-capacity 2″ metallic 2:1 high-pressure AODD pump delivering flow rates up to 92 gpm (348 lpm) and discharge pressures up to 232 psi (16 bar).
When to Use a High Pressure AODD Pump
A high-pressure AODD pump should be considered when the required discharge pressure exceeds the capability of a conventional air-operated diaphragm pump. The Versa-Matic 2:1 design uses additional air chambers and an additional air-side driver diaphragm to increase the force transferred to the pumped fluid.
- Filter press feed applications
- High head pressure systems
- Long-distance fluid transfer
- Viscous or high specific-gravity fluids
- Slurry transfer
- Mine dewatering
- Chemical and industrial process transfer
E1 vs E2 High Pressure Pump
| Specification | E1 High Pressure | E2 High Pressure |
|---|---|---|
| Port Size | 1″ | 2″ |
| Maximum Flow | 33 gpm (125 lpm) | 92 gpm (348 lpm) |
| Maximum Discharge Pressure | 232 psi (16 bar) | 232 psi (16 bar) |
| Maximum Solid Size | 1/8″ (3 mm) | 1/4″ (6 mm) |
| Wetted Materials | Aluminum / Stainless Steel | Aluminum / Stainless Steel |
| Best Starting Point | Lower-flow high-pressure duties | Higher-flow high-pressure duties |
Final pump selection should consider required flow rate, discharge pressure, fluid viscosity, solids size, material compatibility, suction conditions and actual operating requirements.
