Masterflex Pumps versus Solenoid Pumps

Solenoid pumps might be low-priced, however they’re often expensive in terms of downtime and maintenance. Masterflex® peristaltic pumps offer a better alternative for many applications.

Why?Masterflex® peristaltic pumps Solenoid pumps pulse a flexible diaphragm to displace liquid with each stroke—typically, the diaphragm acts against a rigid plate. Timing circuitry energises an electromagnet that slides the diaphragm into discharge position and a system of check valves helps keep the fluid flowing in one direction.

Due to these check valves, solenoid pumps provide very limited suction lift, often making them difficult to restart once they lose prime. Plus, these check valves can wear out quickly and are prone to hanging up, allowing siphoning— all adding up to inefficiencies and unscheduled downtime that can seriously compromise the integrity of critical processes and equipment.

However, the proven peristaltic design of Masterflex pumps provides for incredibly high suction lift —and accurate, reliable performance—without clogging, and without check valves that can jam, cause siphoning, downtime and performance and/or liability issues. Masterflex pumps are self-priming and they can run dry for extended periods without damage. They can’t become vapour-locked, either.Peristaltic_pump in motion_Wikipedia
