Description
The Roper A Series operates at standard motor speeds and is available in flange-mount, foot-mount, and C-face close-coupled configurations. Helical gears provide stronger, quieter performance while compact close coupling supports alignment.
Features:
– Quiet helical gears
– Maintenance-friendly design
– Long-lasting bearings
– Flexible mounting options
Nomenclature
A Series Small
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 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. Shaft Sealing:
The next two digits indicate shaft sealing.
AL = Lip Seal
AM = Mechanical Seal
AP = Packing
C. Theoreticall Displacement:
The next two or three digits indicate the approximate theoretical displacement in US gallons per 100 revolutions [Liters/100 rev].
005 = .005 [.019]
01 = .01 [.038]
02 = .02 [.076]
03 = .03 [.114]
06 = .06 [.227]
08 = .08 [.303]
D. Rotation Directio & Shaft Position:
High Drive:
No letter or W = CW (standard rotation for most sizes)
X = CCW
Y = CW
Z = CCW
Low Drive:
LW = CW
LX = CCW
LY = CW
LZ = 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
B = 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.

D. Rotation Directio & Shaft Position:
The next one or two letters indicate the direction of rotation and shaft position. The letter “L” indicates low drive. If the letter “L” is not used, the shaft position is high drive. Not all rotations are available for all sizes. CW = clockwise rotation; CCW = counterclockwise rotation.
