1.1 This specification covers the requirements applicable to the design and construction of centrifugal pumps for shipboard application. The six classes of service covered by this specification are as follows:
1.1.1 Class 1--Boiler feedwater and other freshwater applications with temperatures above 212oF (100oC),
1.1.2 Class 2--Condensate water,
1.1.3 Class 3--Freshwater except Classes 1 and 2,
1.1.4 Class 4--Seawater in which total head produced per stage does not exceed 50 psi (345 kPa),
1.1.5 Class 5--Seawater in which total head produced per stage exceeds 50 psi (345 kPa), and
1.1.6 Class 6--Hydrocarbon pumps (less than 1500 SSU).
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
