Diaphragm pumps are particularly suited to tolerate abrasive formulations due to their design and construction. These pumps utilize a flexible diaphragm that can move liquid and deal with materials that may contain solid particles, minimizing wear on the pump components. The diaphragm creates a seal that helps prevent leaks and can handle various types of fluids, including those with abrasives, without compromising performance.

In contrast, piston pumps, while efficient for many applications, can suffer from increased wear when dealing with abrasive materials due to the direct contact between the piston and cylinder. Boom sprayers primarily focus on delivering pesticide uniformly across a large area and are not designed for handling abrasive materials specifically. Backpack sprayers, which are manually operated, generally deliver pesticides at lower pressures and are also not equipped to handle abrasive formulations effectively.

Thus, diaphragm pumps stand out for their ability to work with abrasive substances, making them the preferred choice for applications that involve such materials.
