Abstract
A d.c. controller pump includes electronic control mechanisms that permit regulated control within a fluid flow system. A pump head is coupled to a housing allowing the fluid to infiltrate the region surrounding a permanent magnet rotor. Stator windings and control electronics fixed to a plurality of printed circuit boards are isolated from the fluid by means of a solid body that encapsulates the stator windings and seals the rear of the cavity. Hall effect sensor-generators and other assemblies are fixed within the solid body to enhance integrity and reduce parts count. Associated electronics includes a readily-removable circuit board for housing auxiliary electronic functions. The board is mounted in parallel at the rear of the pump housing with boards of sensor and controller electronics. The auxiliary function electronics pump configurations enable both fixed and variable speed operation in accordance with fluid flow system design and parameters.
