Bulk Liquid Series
All Bulk Series pumps are available on baseplates that are custom-designed for each application to ensure product reliability.
Bulk Liquid Series Nomenclature
The Model Number consists of a seven or eight digit number.
The first digit (4) indicates the port arrangement.
- 4 = Straight through ports
The second digit (6) indicates the shaft sealing.
- 6 = Packing
- 7 = Mechanical Seal
The third and fourth digits (11) indicate the approximate theoretical displacement in U.S. gallons per 100 revolutions. Gallons/100 Rev. [Liters/100 Rev.]
- 11 [41.6]
- 17 [64.4]
- 22 [83.3]
- 32 [121.1]
- 35 [132.5]
- 43 [162.8]
- 48 [181.7]
- 58 [219.6]
- 65 [246.0]
The letter or group of letters indicates special model options (precedes letters to indicate pump arrangement).
- E = EVO options included
- C = Cartridge seal provisions
- EC = EVO plus cartridge seal provisions, including ANSI machined for backplate
The letter or group of letters (GHB) indicates the pump head arrangement. Backplate machined for cartridge seal use.
- HB = Pump with outboard bearing
- SBH = Short backplate with outboard bearing and triple lip seal
- GHB = Pump with outboard bearing and built-on gear reduction unit
- BH = Pump without outboard bearing to accommodate close coupled hydraulic drive auxiliaries through a rigid coupling.
- H: Backplate
On GHB pumps, the letter (O) indicates pump with outboard bearing and auxiliary mounting provisions (does not include built-on gear reduction unit).
The letter (F or A) indicates port style
- No letter = Pump with threaded ports
- F = Pump with Roper standard flange ports
- A = Pump with flange facing to accept ANSI flanges
The letters (RV) indicate type of faceplate on pump.
- No letters = Plain faceplate
- RV = RV style single direction relief valve faceplate (Standard RV, Jacketed RV)
- BV = BV style bi-directional relief valve faceplate
The letter or group of letters (X, LX) indicates direction of rotation and shaft position. The letter (L) indicates low drive unit. If the letter (L) is not used, the shaft will be in a high drive position.
- No letter or W = Clockwise Rotation (Standard Rotation)
- X = Counterclockwise Rotation
- Y = Clockwise Rotation
- Z = Counterclockwise Rotation
- LW = Clockwise Rotation
- LX = Counterclockwise Rotation
- LY = Clockwise Rotation
- LZ = 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.

Note: Maximum speed and flow can only be achievable under the correct inlet (suction) and liquid conditions. Liquid viscosity and discharge pressure, plus pumping conditions will determine actual flow (ie. – theoretical minus slip).
