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]

The third digit (S) indicates the housing material.

• S = 316 Stainless Steel
• C = Steel

The fourth digit (S) indicates the gear material.

S = 17-4 vs. 17-4 PH Stainless Steel

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.)

The sixth digit (P) indicates whether or not the pump is equipped with an internal relief valve.

• P = Plain

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.)

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

The ninth digit (D) indicates the bearing material used.

• D = Carbon
• Q = Special (covered by Spec. No.)

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.

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.

The twelfth digit (L) indicates the drive shaft position.

• L = Low drive; Standard
• H = High Drive

The twelfth digit (W) indicates the drive shaft rotation.

• W = Clockwise rotation; Standard
• X = Counterclockwise Rotation

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. 

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. 

• A = low pressure spring  
• B = high pressure spring (standard) 

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.
