Industry:Mining
A pump for lifting to its own level, as distinguished from a force pump. A suction pump.
Industry:Mining
A pump generally of simple construction and heavy design since slurry presents a difficult pumping problem owing to its erosive action. This type pump is generally of the single-stage type as heads are small, with a solid casing of steel or cast iron about twice the normal thickness to provide against erosive action.
Industry:Mining
A pump is said to be working on air when air is sucked up with the water.
Industry:Mining
A pump of the centrifugal type that combines in a single hydraulic stage and with a single hydraulic impeller and casing the dual ability to pump, under vacuum, either liquids or gases. These pumps are advantageously used for sump, bilge, mine water gathering, tankcar unloading, vacuum evaporator applications, chemical processing, and other uses where the liquid is below the pump centerline, or under high vacuum. The suction lift is usually guaranteed at 20 ft (6.1 m) for cold water at sea level.
Industry:Mining
A pump that commands the drainage of underground waters over a considerable area of mine workings, being a substitute for a number of smaller, independent pumps.
Industry:Mining
A pump used for mining and quarrying, as in muddy and gritty water.
