Nomenclature
A. Figure (Model Number):
The FIGURE number consists of an eleven to thirteen digit number.
The first two digits (07) indicates the approximate theoretical displacement in US gallons per 1000 revolutions. Gallons/1000 Rev. [Liters/1000 Rev.]
07 [26.5]
12 [45.4]
18 [68.1]
B. Housing Material:
The third digit (S) indicates the housing material.
S = 316 Stainless Steel
C = Steel
C. Gear Material:
The fourth digit (S) indicates the gear material.
S = 17-4 vs. 17-4 PH Stainless Steel
D. Drive:
The fifth digit (1) indicates the drive configuration.
1 = Standard Coupled without outboard bearing
2 = Standard Coupled with outboard bearing
3 = Mag drive, 5 lb/ft torque, Neodymium
7 = Special (covered by a Spec. No.)
E. Internal Relief Valve:
The sixth digit (P) indicates whether or not the pump is equipped with an internal relief valve.
P = Plain
F. Shaft Seal:
The seventh digit (T) indicates the type of shaft seal.
T = Single Mechanical Seal
U = Packing
W = Sealless (mag drive)
X = Special (covered by Spec. No.)
G. Elastomer Material:
The eighth digit (Y) indicates the elastomer material used.
Y = PTFE Encapsulated
Z = Solid PTFE
K = Kalrez®
V = Viton®
N = Buna
E = EPDM
X = Special covered by Spec Number
H. Bearing Material:
The ninth digit (D) indicates the bearing material used.
D = Carbon
Q = Special (covered by Spec. No.)
I. Pump Mounting:
The tenth digit (G) indicates the type of pump mounting.
G = Pump with feet. (Use only with “H” or “M” in the eleventh position.)
J = Footless mag drive or standard drive pump and/or bracket (Mag or Standard Drive).
I = Mag drive pump with feet on bracket.
J. Final Unit Shipped:
The eleventh digit (H) indicates the final unit shipped.
H = Bare pump without accessories (includes the bracket and coupling on mag drive pumps).
M = Mounted pump and accessories. (Includes base or bracket mounted standard drive pumps with or without the motor.)
O = Pump less bracket and coupling for footless pumps and mag drives. O is not to be used for standard drive pumps with feet; use H for these.
K. Drive Shaft Position:
The twelfth digit (L) indicates the drive shaft position.
L = Low drive; Standard
H = High Drive
L. Drive Shaft Rotation:
The twelfth digit (W) indicates the drive shaft rotation.
W = Clockwise rotation; Standard
X = Counterclockwise Rotation
M. 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.
N. 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.
O. Spring:
A = low pressure spring
B = high pressure spring (standard)
P. 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.
