Overview

The LSP is Franklin’s self-priming lawn sprinkler pump, with a cast iron casing and seal plate, a 5/8 in rotating mechanical seal, dual-voltage 115/230V motor, and 2 in NPT suction with 1-1/2 in NPT discharge. Sprinkler pumps run seasonally and hard, so the seal and impeller are the usual wear parts.

This page also carries the repair parts Franklin lists for its CE series and its non-corrosive pumps. Each part is listed against the pump it fits.

Before You OrderMatch the pump model from the nameplate, not the horsepower alone. Replace the mechanical seal and the seal plate O-ring together, and check the impeller for wear while the pump is open.
