Waste vacuum pump, also named as solids transfer pump. It is a pneumatic slurry transfer vacuum pump for liquid, slurry, and solids transfer. With special structure design, it can be used at tough environmental for solids transfer, high working performance and less maintenance. The pump can transfer material with high gravity and high density, solids content max. up to 80%. Material transfer applications: Waste mud and waste solids discharged from shale shaker, mud cleaner and centrifuge transfer Drilling mud transfer Waste pit cleaning Hazardous waste recovery Oil sludge, tank bottoms residual removal and transfer Barge holdings and vessel bottom clean out Bulk tank and silo transfer of material Sand; Course, fine, conventional and frac sand Diatomaceous earth Animal waste etc.
