Specific Considerations for Plastic, Cast Iron, and Stainless Steel Diaphragm Pumps
Why is cast iron the ideal material to make pumps out of? One of the many applications of Air Operated Diaphragm Pump is the manufacture of pumps. Sump pumps and centrifugal pumps work best with cast iron. Due to its mechanical and physical properties, cast iron is the preferred material for constructing pumps. The ideal metal for high-temperature applications depends on three parameters.
Corrosion protection As the temperature rises, the liquid gets corrosive. Corrosion doesn’t affect cast iron too much. For pumps that are utilize in hot environments also Cast Iron Diaphragm Pump is the material of preference.
Maximum temperature A thermal shock is a sudden change in temperature that harms metal. This may occur when you start a cold pump with hot oil or when you clean it with cold water. Diaphragm Pneumatic Pump Pumps made of cast iron also may function at temperatures as low as 650 degrees Fahrenheit. Below this temperature, they successfully endure thermal shock to a good extent.

Thermal expansion coefficient: Thermal expansion may result in dimensional changes in the pumps’ external components, which could cause the Stainless Steel Diaphragm Pumps to fail. also Dimensional changes may interfere with the fittings and impact the pump’s running clearances. In the casing, parts like the bushing, idler pins, and bushings may start to interfere with one another and even move out of position.
Over time, a plastic diaphragm pump’s shape may slightly alter. The plastic Diaphragm Pump need to be checke more frequently to make sure the fasteners securing the pump casing are still secure. The only additional factor for a Double Diaphragm Pump is to confirm that the substance being pump is compatible with also the plastic of the pump.
