ASTM F998-00

Standard Specification for Centrifugal Pump, Shipboard Use

SCOPE
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.
