ARO 66605J-388 double diaphragm pump ensures efficient and safe transfer of fluids and is ideal for transferring chemicals, slurries and viscous liquids. It is used in chemical processing, paint manufacturing, wastewater treatment and food production operations.
Working Mechanism:
- When air is directed into one diaphragm chamber, it displaces that diaphragm, increasing the volume of the chamber.
- This change in volume creates reduced pressure, causing fluid to be drawn in through an inlet valve.
- The other diaphragm chamber contracts as its diaphragm is pushed outward, expelling the fluid through an outlet valve.
- When the air supply is switched, the process reverses and the reciprocating motion continues, facilitating a continuous fluid flow.
Features:
- It features self-priming capabilities, eliminating the need for external assistance to initiate fluid transfer.
- This ARO air diaphragm pump offers a reliable ball valve design for controlled fluid flow, reducing leakage risks.
- It has polyurethane construction, offering structural rigidity and lightweight.
- This ARO double diaphragm pump has a low air consumption rate of 20 scfm, conserving energy while providing efficient fluid transfer.
- It is equipped with a bolt assembly type, simplifying maintenance and minimising downtime during repairs.
Frequently Asked Questions:
Q. How can I choose the right double diaphragm pump for my application?
A. Factors to consider include the type of fluid, flow rate requirements, pressure, temperature, chemical compatibility, and the environment in which the pump will operate.
Q. What maintenance is required for a double diaphragm pump?
A. Regular maintenance includes inspecting diaphragms, checking valves and ensuring that air lines are clean and free from blockages. Lubrication and periodic replacement of diaphragms may be needed, depending on usage.
Q. What safety measures should be taken when using double diaphragm pumps for hazardous fluids?
A. Safety precautions include using appropriate materials, ensuring proper ventilation, employing safety protocols and providing operator training to handle hazardous fluids safely.
Q. What is the operating temperature of this ARO 66605J-388 double diaphragm pump?
A. It has an operating media temperature range of -10 to 150 degrees F.
Q. What factors should I consider when installing this diaphragm pump?
A. Ensure that the pump is stable. Firmly secure it to a rigid base and verify that the inlet and outlet connections are adequately dimensioned. Moreover, check for factors such as ambient temperature, humidity levels and the suitability of materials in relation to the pumped fluid.
Q. What is the flow rate of this ARO air-operated double diaphragm pump?
A. This pump has a flow rate of 100 psi at 13.1 gpm.
Q. How should I clean this ARO 66605J-388 pump after use with different fluids?
A. Before utilising the pump with a different fluid, it is essential to rinse the pump with the recommended solvent that corresponds to the previously pumped fluid. Also, carefully disassemble the unit, perform a thorough cleaning and conduct a proper inspection of all components that come into contact with the fluid.
