Nomenclature
A. Figure (Model Number):
The first and, in some instances, the second digits indicate the mounting arrangement and relief valve (RV).
1 = Foot mounted, No RV
2 = Foot mounted with RV
17 = Flange mounted, No RV
18 = Flange mounted with RV
25 = Baseplate mounted, No RV
26 = Baseplate mounted with RV
33 = Close Coupled, No RV
34 = Close coupled with RV
B. Pump Series:
The next digit indicates F series: F
C. Theoretical Displacement:
The next two or three digits indicate the approximate theoretical displacement in US gallons per 100 revolutions [Liters/100 rev].
F1 = .00086 GPR (3.2 CC/REV)
F3 = .002 GPR (7.6 CC/REV)
F5 = .003 GPR (11.4 CC/REV)
F10 = .007 GPR (26.5 CC/REV)
F15 = .0103 GPR (39.0 CC/REV)
F20 = .0124 GPR (46.9 CC/REV)
F35 = .034 GPR (128.7 CC/REV)
F50 = .050 GPR (189.3 CC/REV)
F75 = .075 GPR (283.9 CC/REV)
F100 = .0107 GPR (405.0 CC/REV)
F150 = .186 GPR (704.1 CC/REV)
F200 = .232 GPR (878.2 CC/REV)
D. Rotation & Shaft Position:
The next letter indicates the direction of rotation and shaft position. All rotations are facing the drive shaft end. Not all rotations are available for all sizes. CW = clockwise rotation; CCW = counterclockwise rotation.
High Drive:
No letter or W = CW (standard for most sizes)
X = CCW
E. 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.
F. Type:
The TYPE number is a number used by Roper Pump Company for in-house identification of construction. Always include the type number in any references to the pump.
G. Spring:
A = low pressure spring (standard)
B = high pressure spring
C = high pressure spring (standard)
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.
