What to do if the pump stops in Alfa Laval Emmie?

T
Tony NguyenAug 20, 2025
If the pump in your Alfa Laval Cleaning Equipment stops, it might be due to a few reasons. The collecting tank might be full, in which case you should empty it and restart the pump. Another possibility is an overload caused by a clogged strainer; clean the strainer, noting that the motor protector in the control unit resets automatically. If the counter pressure at the separator outlet is lower than 50 kPa, check that the suction inlet is not above the surface in the tank, inspect for any obstruction in the inlet line, verify the function of the regulating valve, and adjust the counter pressure. Also, ensure the feed through the whole system is sufficient, as an overload could be caused by an obstructed inlet or outlet side.
