Nomenclature
Figure (Model Number):
The FIGURE number consists of a nine digit number.
The first digit (3) indicates the port arrangement.
3 = 3800 Series with right angle ports
B. Pump Series:
The second digit (8) indicates the pump series.
C. Theoretical Displacement:
The third and fourth digits (48) indicates the approximate theoretical displacement in U.S. gallons per 100 revolutions. Gallons [Liters]/100 Rev.
32 [121.1]
43 [162.8]
48 [181.7]
58 [219.55]
D. Port Style:
The letter (F) indicates port style.
F = Pump with Roper standard flange ports
No Letter = indicates threaded ports.
E. Rotation / Port Configuration:
The last letters usually indicate the rotation and port configuration. Rotation and port configuration is viewed from the drive end of the pump.
W = Clockwise rotation, inlet on left, high drive.
Z = Counter-clockwise rotation, inlet on right, high drive.
X = Counter-clockwise rotation, discharge on left, high drive.
Y = Clockwise rotation, discharge on right, high drive.
LW = Clockwise rotation, discharge on left, low drive.
LZ = Counter-clockwise rotation, discharge on right, low drive.
LX = Counter-clockwise rotation, inlet on left, low drive.
LY = Clockwise rotation, inlet on right, low drive.
F. Spec:
Occasionally, special pumps or configurations are required which are unique for a particular application. These modifications are clarified by a SPECification number. Identification of any items different than a standard pump can be made by consulting Roper Pump Company or an authorized distributor.
G. Spring:
A = low pressure spring (standard)
B = high pressure spring
H. Serial Number:
The SERIAL number is a unique number assigned to each pump built by Roper Pump Company.
*In any communication concerning this pump, always be sure to include the Figure, Spec, Serial, and Type numbers so proper identification of the pump can be assured.
