NAMEPLATE DATA
Roper Pump Company identifies each pump manufactured by a metal nameplate attached to the pump. This
nameplate describes the pump as built at the factory. Copy the nameplate data from your pump in the area provided
below. Use this for ready reference when ordering repair parts or when consulting with a Roper distributor or Roper
Pump Company about this pump.

A. Figure (Model Number)
The figure number consists of a five, six, or seven digit number.
 The first and, in some instances, the second digits indicates the mounting arrangement and relief valve (RV).
1 = Foot mounted, No RV 25 = Baseplate mounted, No RV
2 = Foot mounted with RV 26 = Baseplate mounted with RV
17 = Flange mounted, No RV 33 = Close Coupled, No RV
18 = Flange mounted with RV 34 = Close Coupled with RV
 The next digit indicates F series: F
 The next two or three digits indicate the approximate theoretical displacement in US gallons per 100 revolutions
[Liters/100 rev].
F1 = .00086 (3.2 CC/REV) F15 = .0103 (39.0 CC/REV) F75 = .075 (283.9 CC/REV)
F3 = .002 (7.6 CC/REV) F20 = .0124 (46.9 CC/REV) F100 = .107 (405.0 CC/REV)
F5 = .003 (11.4 CC/REV) F35 = .034 (128.7 CC/REV) F150 = .186 (704.1 CC/REV)
F10 = .007 (26.5 CC/REV) F50 = .050 (189.3 CC/REV) F200 = .232 (878.2 CC/REV)
 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. See pages 9 thru 14 for illustrations and further explanation of directions of
rotations. CW = clockwise rotation; CCW = counterclockwise rotation.
High Drive:
No letter or W = CW (standard rotation for most sizes)
X = CCW
B. Spec
Occasionally, special pumps or configurations are required which are unique for a particular application. These
modifications are clarified by a SPEC ie: specification number. Identification of any items different than a standard
pump can be made by consulting Roper Pump Company or an authorized distributor.
Spec 0 – Mechanical Seal, Tapped Ports Spec 17 – Mechanical Seal, Flanged Ports
Spec 5 – Packed Box, Tapped Ports Spec 174 – Packed Box, Flanged Ports
C. Type
The TYPE number is a number used by Roper Pump Company for in-house identification of construction and
hydraulics. Always include the type number in any references to the pump.
