How do I maximize the benefits of the internal bypass in the Micropump products?
The relief valve is a mechanism used to control or limit pressure by allowing the fluid to flow into an auxiliary passage, away from the main flow path. The valve is set to activate at a predetermined pressure. As the discharge pressure on the outlet side of the pump increases, so does the pressure within the magnet cup. When this pressure exceeds the force of the bypass spring poppet, fluid is diverted through the auxiliary passage to the pump inlet. Users should be aware that over a prolonged period, the energy of fluid movement and friction will cause an increase in fluid temperature. This is a primary concern when the bypass is used to recirculate a large percentage of fluid in a low volume, closed-loop system. This feature often eliminates the need for costly external plumbing and helps to prevent overloading of your system.
