We use water pump (stainless steel case & Impeller) to handle edible oil, from storage tank to buffer tank, we calculate the available head is around 20m head, the pump head range min 10m max 35m, we install pressure gauge, reading is 24m (2.4bar) which is efficient point in pump curve, the rated current is 4.4A
The problem is, pump tripped out because of over current which is 4.55, 4.6, 4.8 A, we contact the manufacturer he advice to increase the overload 5%, the pump now not tripped out, but the current reading still high, and the motor is hot which is will lead to motor damage.
we don't know where is the problem since there is no process problem, is it application problem when we use water pump in edible oil application?
