DESCRIPTION AND SPECIFICATIONS
The I-Series are single-stage, end suction, centrifugal pumps
for general liquid transfer, booster applications, irrigations, and
general service pumping.
Pump impellers are fully enclosed, key-driven, and held in position
by an impeller bolt and washer. Casings are full volute in design.
Based on the diversity of applications and requirements within which the I-Series pumps are installed, the configurations, materials of
construction, and specifications may significantly vary within the models available. Therefore it is the responsibility of the installer and
customer to confirm the model of pump and reference catalog information accordingly to identify the specifics of the unit prior to installation.
Additionally, assistance is available from a Franklin Distributor or by calling the Franklin Hotline.

Dependent on the pump size, the suction and discharge
connections will be threaded, flanged or victaulic. Shafts are
protected with replaceable shaft sleeves.
Close-coupled units have NEMA-standard JP motors with C-face
mounting and key-driven shaft extension. SAE drive units bolt
directly to the engine flywheel housing for SAE sizes 1, 2, 3, 4 or 5.
Optional elastomer element couplings are available for 6.5-,
7.5-, 8-, 10-, 11.5-, and 14-inch flywheels. Frame-mounted units
can be coupled to motors through a shaft-to-shaft coupling, or
belt-driven.
