Sludge vacuum pump, also named as solids transfer pump. It is a pneumatic slurry transfer vacuum pump for liquid, slurry, and solids transfer.
Since it’s a high vacuum loading solids transfer pump, it can be used at tough environmental for solids or sludge transfer with high working performance and less maintenance.
The pump can transfer material with high gravity and high density, with dry solids material or slurry with solids content max. up to 80%.
