“SUGAR-HOUSE” PUMPS.
The handling of semi-liquids, commercially known as thick stuff, has always been considered more or less of a serious problem, and many designs of mechanism in the form of pumps have been invented for that purpose.
For pumping tar the improved forms of rotary pumps have recently come largely into use. These will be described later under their proper heads. Fig. 212, page 232, Part one, represents a very satisfactory design of plunger pump for handling the heavy stuff alluded to.
The Deane single sugar-house pump is shown in Fig. [452]. These are largely used for pumping molasses, syrup, cane-juice, melter-pan products, etc., and are fitted with linings, valves, etc., to best suit the condition of the fluid to be pumped.
The valves are very large and the motion of the pumps is somewhat slower than for water. By removing one set of bolts all the valves are uncovered.
These products of the sugar-house when of a high temperature can be pumped nearly as fast as water; the following list gives the approved proportions of these pumps.
