What is a Diaphragm Pump? Designed by Dorr Oliver, the ODS Diaphragm Pump transfers slurry materials evenly and simply utilizing air. Each of these pumps can be automated to match your processing capacity to see maximum efficiency.

With this low-maintenance and durable design, ensure your process remains up and running during dry operations and avoid complications from potential environmental contamination.

Benefits of a Diaphragm Pump:

• Temperature Conditions: This design can handle extreme conditions up to 200 degrees Fahrenheit (93.3 degrees Celsius) and slurries up to 75% solids.

• Material Handling: Each Dorr Oliver Diaphragm Pump can handle materials such as:
  1. Delicate crystal slurries
  2. High abrasive slurries
  3. Extremely volatile slurries
  4. Unstable slurries

The Door-Oliver ODS Pump has many benefits in addition to the above:

• Adjustable under operation for maximum capacity and discharge pressure flexibility
• Leak-proof, rhythmic plunger minimizes particle degradation of even the most delicate slurries
• Capable of pule transfer thickening through constant pumping velocity matched to accumulation rates
• Managed through an ODS Pump timer control panel
