Description of the pump
The Wilo-Para MAXO high-efficiency circulators (Fig. I) are glandless pumps consisting of highly efficient hy-
draulics, an electronically commutated motor (ECM) with a permanent magnet rotor and integrated differen-
tial pressure control. An electronic control module with an integrated frequency converter is on the motor
housing. Control mode and delivery head (differential pressure) are adjustable. The differential pressure is
controlled via the pump speed.
