A pump valved so as to discharge liquid at only one end of the water cylinder. Compare: double-action pump
Industry:Mining
A pump which discharges the same amount of water for a given power, regardless of the head against which it operates.
Industry:Mining
A pump whose water cylinders are equipped with intake and discharge valves at each end; hence liquid is delivered by the pump on both the forward and the backward strokes of the pump piston.
Industry:Mining
A pump with a rotating mechanism that gathers a fluid at or near the circumference of radial tubes and discharges it at the axis.
Industry:Mining
A pump with a shrouded impeller and receiving the water at its center. A diffusion ring containing vanes surrounds the impeller and directs the impeller discharge into a circular casing, which delivers into the eye of the next impeller in series. The diffusion ring converts the high-velocity discharge of the impeller into pressure head. The turbine pump is widely used in mines.
Industry:Mining
A pump, similar to a diaphragm pump, that is not capable of delivering water above its own height.
Industry:Mining
A pump, usually of the single-stage, single-entry, overhung type, that must have low suction loss and high-temperature features since it draws water directly from the boiler drums at high saturation pressure and temperature.
Industry:Mining
A pumpable thin slurry consisting primarily of a mixture of cement, sand, and water; injected into rock formations through boreholes as a sealant.
