Which type of pump is known for its abrasion resistance against wettable powders?

The diaphragm pump is specifically designed for handling materials that include abrasive substances, such as wettable powders. It operates by using a flexible diaphragm that moves back and forth, creating a positive displacement of the liquid being pumped. This design minimizes wear on the pump components when working with abrasive materials, as the diaphragm can effectively contain slurries and protect the pump mechanisms from the damaging effects of the solid particles in the mixture.

In applications involving pesticide formulations, where wettable powders often require dilution in water, the diaphragm pump can maintain efficient flow rates and pressure while ensuring longer service life due to its abrasion-resistant properties. This makes it particularly suitable for pest control applications in various settings, enhancing both performance and reliability.

Other pump types, while effective for various purposes, do not offer the same level of resistance to wear from abrasive materials. For example, centrifugal pumps, though widely used for liquids, may experience significant wear when handling solid-laden fluids. Gear pumps operate differently and may not handle abrasive particles well either, as the tight tolerances can be affected by wear over time. A wiping applicator, on the other hand, serves a different purpose altogether in applying substances rather than pumping them.
