The above table is based on a steam pressure of 45 to 50 pounds per
square inch of steam piston, and the vertical height is from lower end
of suction pipe to discharge.
Fig. 438 is designed to show a pump largely used by miners in
prospecting. It is double levered so that four men or more can operate
it, two to each lever. The plunger and valves are so designed that they
will lift muddy or gritty water without injury to these parts.
An electric mining pump is shown on page 276, part one. This is a
portable pump mounted on a car running on rails and is designed for the
work appertaining to a mine in steady operation.
On page 340, part one, is illustrated a powerful pump with four outside
packed plungers designed for mining purposes.
