Hello, Friends

We Order low viscosity Base oil and concentrate coolant in flexy bags in containers that are brought by a trailer and remain on a wagon till the discharge.
(about 1.5m height). I connect a 2'' gear pump and flexible hose and transfer to IBC or a storage tank near by, it's valve about 2 m height. The thing is that i can't get the bag drained 100%. Even if folded or lifted. I think that too much is left, about 50 kg.
if it was 2-5 kg, fine but this is different.

Any advice?
