High pressure slurry pump for biomass / magnetic particle (Double cylinder type)

Our slurry pump can feed the slurry into a high pressure line in a stable manner. The slurry pump consists of cylinders, a plunger pump that supply the water to the cylinder, and a raw material tank. The slurry in the cylinders pumps by the water supply at a maximum pressure of 30MPa. The cylnders and the raw material tank have a stirrer to make the slurry homogeneous. This type is not a magnetic stirrer but an impeller type stirrer, which has high stirring capacity and can handle biomass and magnetic materials.
Slurry supply from the raw material tank to the cylinders can be made by compressed air. This is a double cylinder type, thus it can be operated continuously; the slurry feeding will not stop when either cylinder is empty.
Rotating mechanism to tilt the cylinder allows disassembly and cleaning the cylinder, and rotor blade replacement even with a large stirrer. A touch panel is used for operation, making it easy to operate while viewing the status of the slurry pump.
