5. Setup & Installation

Proper installation is crucial for the pump's performance and longevity.

1. Mounting: Securely mount the pump on a stable, level surface capable of supporting the pump's weight and any associated piping and fluid.
2. Fluid Connections:
   • Connect the fluid inlet line (1/2 inch NPT) to the bottom port of the pump. Ensure the suction line is as short and straight as possible to minimize friction loss.
   • Connect the fluid outlet line (1/2 inch NPT) to the top port.
   • Use appropriate thread sealant on all fluid connections to prevent leaks.
3. Air Connection:
   • Connect a clean, dry, regulated air supply to the 1/4 inch NPT air inlet port.
   • An air filter, regulator, and lubricator (FRL unit) are recommended for optimal performance and pump life.
   • Ensure the air supply pressure does not exceed 100 PSI.
4. Priming: For initial startup or after maintenance, ensure the pump is primed by allowing fluid to fill the pump chambers before applying air pressure. This can often be achieved by gravity feeding the fluid to the pump inlet.

6. Operation

Follow these steps for safe and effective pump operation.

1. Pre-Operation Check:
   • Verify all fluid and air connections are tight.
   • Ensure the fluid supply is adequate.
   • Confirm the air regulator is set to the desired operating pressure (do not exceed 100 PSI).
2. Starting the Pump:
   • Slowly open the air supply valve to the pump. The pump will begin to cycle.
   • Adjust the air pressure to achieve the desired flow rate. Higher air pressure generally results in higher flow.
3. Stopping the Pump:
   • Close the air supply valve to the pump.
   • If necessary, close fluid inlet and outlet valves.
   • Depressurize the system before any disconnection or maintenance.

7. Maintenance

Regular maintenance ensures optimal performance and extends the life of your pump.

• Routine Checks (Daily/Weekly):
  • Inspect for any fluid or air leaks.
  • Check air filter for condensation and drain if necessary.
  • Listen for unusual noises during operation.
• Diaphragm and Valve Ball Inspection (Periodically):
  • Depending on fluid type and usage, diaphragms and valve balls may wear over time.
  • If performance degrades (e.g., reduced flow, inconsistent cycling), inspect these components for wear, cracks, or swelling.
  • Replace worn parts with genuine replacement parts.
• Cleaning:
  • Flush the pump with a compatible cleaning solution or clean water after use, especially when pumping corrosive or viscous fluids.
  • Ensure the pump is thoroughly drained before storage.
