ABSTRACT:
A slurry pump has a hopper containing slurry. A pumping cylinder containing a piston communicates with the hopper through the hopper wall. A delivery tube is swung into and out of register with the cylinder. Slurry is drawn into the cylinder by the piston and out through the delivery tube. The pump is controlled by a lever which has a central neutral position and two operating positions.
Dangerous moving parts are covered by a guard mounted on hinges. An arm on the guard engages a slide which has a channel. If the guard is moved from its closed position, the arm slides the slide so that the control lever enters the channel and moves to its neutral position. The external moving parts include releasable clamping means for sealing the junction of the delivery tube and the cylinder while slurry is being transferred from the cylinder to the tube.
