Leland Air-Operated Diaphragm Chemical Pump Designs & Their Advantages

Fluid-handling devices that employ air pressure to transfer fluids include air operated diaphragm chemical pumps. They are available in several designs, including single- and double-diaphragm models, ball valve layouts, and nonmetallic wetted component setups. These pumps are adaptable and reasonably priced. They can tolerate caustic or abrasive fluids, have high flow rates, and can prime themselves.

They can be used even if the liquid levels change because they are self-priming and can run dry without causing damage. Additionally, they require relatively little maintenance and can deliver a constant flow rate. Last but not least, because these pumps are air-operated, they are simple to install and use a small amount of electricity.

• Liquid Level Control - The FTI Liquid Level Control is a pneumatic/mechanical device that will automatically turn the pump on and off as the liquid level changes
• Filter/Regulator - Compact, integrated design saves space and reduces piping, includes dual scale psi/Bar gage. Filters incoming air to five microns. Regulator adjusts air pressure from 7.3 to 120 psi (.5 to 8.3 bar).
• SPILLSTOP - Fully pneumatic system safely captures leaked product due to diaphragm failure and automatically shuts down failed pumps to eliminate costly product loss and prevent hazardous spills.
• Pulsation Dampeners - Removes virtually all hydraulic shock while producing a near steady flow of fluid. Protect piping, valves and fittings from destructive pulsations and surges. Available in a wide range of materials of construction
• AODDampener - AODDampener is unique pulsation dampener manufactured from 316L stainless steel with PTFE backed diaphragm, has fully automatic air control and handles a wide variety of applications.
• Cycle Counter - The FTI Air Cycle Counter is an electronic device that counts pump cycles by detecting the presence of the valve carrier. The cycle counter can be universally used on any new or existing FTI Air pump with the proper air valve components.
