This specification is written to obtain reliable,
long-lasting pumps that are suited for the purpose
intended at the most economical price. It requires
the use of grease- or oil-lubricated bearings and
packing glands, and permits the manufacturer to use
his standard castings for the suction bell and the
bowls.
