Stalling occurs when the pump does not receive enough air to complete its cycle, causing interruptions in the pumping [...]

Air operated double diaphragm pumps are an excellent choice for transfer applications due to their simple design, which makes operation easy and repairs inexpensive. To obtain optimal performance, the pump must be correctly installed and operated. Despite their durability mishandling during the priming phase can result in inefficiencies pump damage or complete malfunction. To ensure peak performance and longevity of your AODD pump it's vital to steer clear of priming errors. In this guide, we will discuss about the coming mistakes to avoid when priming an air operated pump. Understanding Priming in Air Operated Pumps Priming is the process of preparing a pump to operate by removing air from the pump and its suction line, allowing the pump to create the necessary vacuum to draw liquid. For air-operated pumps, priming is essential because these pumps rely on air pressure to move diaphragms that, in turn, move the fluid. Without proper priming, the pump cannot function correctly, leading to cavitation, reduced flow rates, and potential damage. Common Mistakes to Avoid Ignoring Manufacturer's Instructions: One of the most prevalent mistakes is neglecting to follow the manufacturer’s instructions. Each air-operated pump model has specific requirements and guidelines provided by the manufacturer. These instructions include detailed steps for priming, recommended pressures, maximum vertical suction lift and maintenance schedules. Ignoring these can lead to improper priming and subsequent pump failure. Solution: Always read and adhere to the manufacturer’s manual. This will ensure that you are using the pump within its designed parameters and following the correct priming procedure. Incorrect Air Pressure Settings: Air-operated pumps require a specific air pressure to operate efficiently. Too low pressure can prevent the pump from priming correctly, while too high pressure can damage the diaphragms and other components. The AODD pump draws fluid by creating a low-pressure zone within the fluid bowls, which is below the atmospheric pressure of 14.7 psi. If the air pressure supplied to the pump is too high, it causes the [...]
