In the food and beverage industry, maintaining the highest standards of hygiene and product quality is paramount. Sanitary diaphragm pumps, designed specifically for these applications, offer exceptional performance and reliability. In this article, we will delve into the features, benefits, and applications of sanitary diaphragm pumps.

Cavitation in diaphragm pumps occurs when localized pressure drops below a critical value, causing liquid vaporization and bubble formation. These bubbles collapse under high pressure, leading to mechanical erosion, chemical corrosion, and component damage. Key causes include long or narrow suction pipes, high liquid temperatures, impurities, and insufficient inlet pressure. Symptoms of cavitation include increased noise, vibration, reduced flow, and unstable pressure. To mitigate cavitation, strategies such as optimizing flow paths, reducing suction loss, adjusting pump speed, and using cavitation-resistant materials are recommended. Implementing these measures can enhance pump performance and longevity while minimizing operational disruptions.

The diaphragm pump should have no abnormal sound during operation, no running, bubbling, dripping or leaking in all parts, the pressure gauge and control valve should work reliably, and all performance indicators should reach the rated capacity in the manual or meet the production requirements. However, due to normal wear or aging of parts and materials, failures may also occur.

Proper installation of a pneumatic diaphragm pump is essential for maximizing its lifespan, ensuring efficient operation, simplifying maintenance, and preventing costly repairs. This involves understanding the pump's working principle, selecting an appropriate location with a clean compressed air source (including potential air filter installation), following correct installation steps (such as proper pipe connections and muffler use), and adhering to crucial precautions (like sealing pipes and avoiding excessive suction/discharge heads). Finally, a thorough post-installation check is vital to confirm proper function and prevent leaks.

Air operated diaphragm pumps (AOD pumps) are versatile industrial pumps powered by compressed air. They excel at transferring various liquids, including viscous, corrosive, and particle-laden fluids, making them ideal for diverse applications. Their key advantages include adjustable flow, safe operation in hazardous environments, self-priming capabilities, portability, and simple maintenance. GODO PUMPS offers a wide range of AOD pumps in various materials to suit specific industry needs, from chemical and pharmaceutical to wastewater treatment and mining. They can also be integrated with automated systems and offer diaphragm rupture alarm functionality for enhanced safety.

Diaphragm pumps operate by using a reciprocating diaphragm mechanism, driven by compressed air or an electric motor, to draw in and expel liquid. Two diaphragms work in tandem, creating alternating suction and pressure. One-way ball valves ensure unidirectional flow. A simple syringe experiment illustrates the principle, highlighting the crucial role of check valves in preventing backflow and enabling efficient pumping. GODO diaphragm pumps are suitable for various liquids, including high-viscosity fluids up to 10,000 CPS.
