ABSTRACT:
The present invention relates to a slurry pumping apparatus for solid-liquid separation. More specifically, the invention provides, in a slurry pumping apparatus arranged such that a diaphragm pump connected to an oil tank is actuated to deliver a hydraulic oil when a predetermined amount of slurry is supplied from a slurry tank to a solid-fluid separator, such as a filter press, which obtains cake from slurry, a slurry pumping apparatus for solid-liquid separation in which the diaphragm pump has its hydraulic pressure chamber connected to a supply/discharge pump through a changeover operation of a change-over valve such that the slurry is pumped to the solid-liquid separator by the operation of the diaphragm pump.
