are in compliance with this specification. Minor deviations in materials may be allowed in the pumps at the
discretion of the Bureau of Ships. The pressure, capacity, and other characteristics of units for qualification
tests shall be as arranged between the Bureau of Ships and the exhibitor. The units shall have Characteristic
ratings of not less than the following:
Rated capacity . . . . . . . . . . . . . . . . . . ..200 g.p.m.
Discharge pressure . . . . . . . . . . . . . . ..50 p.s.i.
Suction lift . . . . . . . . . . . . . . . . . . . . . . 10 inches mercury (Hg) at 500 SSU
