EXPLANATION OF UNIT NUMBERS:
Example VSA-4A-3-4; VSA is the type of pump (suspended wet-pit non-clog sewage pump); -4 is the discharge size (4"); A is the volute size (f = small volute; A or C == medium volutes; E or H = large volutes); -3 is the motor horsepower; and -4 is the motor speed (-4 = 4-pole 1750 RPM; -6 = 6-pole 1150 RPM).
