Industrial Diaphragm Pumps
Flojet industrial-grade diaphragm pumps are designed to transfer liquids with low, medium or high viscosities. These pumps feature a polypropylene housing combined with a sealed motor that enables the pump to handle a higher dry vacuum. The self-priming design of these pumps allows them to be installed above the supply tank level. They are further integrated with a sealed pressure switch that automatically starts and stops the pump when the discharge valve opens and closes, respectively. Selected models come with a built-in thermal protector to switch off the device, in case of overloading. Choose from a wide range of these diaphragm pumps available in flow rates ranging from 2.3 to 3.5 gpm, on Raptor Supplies.
Working Mechanism
- Industrial diaphragm pumps use a flexible diaphragm as their main component.
- When the diaphragm moves, it creates a vacuum, drawing fluid through an inlet valve.
- As the diaphragm reverses its motion, it pressurises the fluid, forcing it out through an outlet valve.
- The diaphragm's back-and-forth motion moves fluid through the system.
Features
Flojet Duplex II DIaphragm Pumps :
- They are self-priming up to 8 feet and can run dry without causing any damage.
- These industrial diaphragm pumps have a built-in backflow preventer to prevent the reverse flow of fluids.
Flojet General Purpose Pumps:
- They are self-priming up to 10 feet and have stainless steel hardware for corrosion resistance.
- These pumps are equipped with thermal overload protectors for safety from overheating conditions.
- They have glass-filled polypropylene bodies for chemical resistance.
Frequently Asked Questions
What is the difference between single diaphragm and double diaphragm pumps?
Single diaphragm pumps have one diaphragm, while double diaphragm pumps have two diaphragms that work alternately, providing continuous fluid flow.
What are the safety considerations when using diaphragm pumps?
Safety precautions include proper installation, maintenance and the use of appropriate protective equipment, especially when handling hazardous chemicals.
What is the difference between air-operated diaphragm pumps and electric diaphragm pumps?
Air-operated diaphragm pumps use compressed air to move the diaphragm, while electric diaphragm pumps use an electric motor. Air-operated pumps are often chosen for their explosion-proof and portable nature.
