Filter press paint pigment
Process
VF65 pumps paint pigment to a filter press. The paint is pressed to produce a powder which is lighter and cheaper to ship. This pump is used without a frequency inverter and always runs at full speed controlled by a timer.
Problem
Paint pigment is very abrasive, causing wear issues with previous pump. Bidirectional pumping is useful to clear infrequent line blockages. The viscous paint causes significant friction losses and a high working pressure.
