Filter press paint pigment
Process
Verderflex VF 80 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.
Solution
The Verderflex VF 80 is abrasion resistant - hose life is not determined by the pumped liquid. Hose pumps are reversible and work at up to 16 bar. The only paint contact part is the easily changed hose, which has a typical life of over one year.
