According to the University of Oklahoma, cost is a major advantage of roller pumps. This cost includes the original purchase price and cost of maintenance. If the pump wears out, the major components are inexpensive and easy to replace.
Experts at Kansas State University report that a roller pump is versatile and adaptable to different fluids. This is especially true for agricultural sprayers, where a variety of fertilizers and pesticides have to be sprayed in the same day. Nylon or Teflon components are the recommended materials for multipurpose pumps.
A roller pump can operate using low RPM equipment. For a pump to start working, the RPM can be as low as 300. This is easy to accomplish with the Power Take Off (PTO) of a tractor or other low RPM engine. Other types of pumps may not start to "kick in" until they reach a higher shaft RPM.
