The heaviest-duty contactor in the Tornatech JP-series family, CONLOV0004 is rated for 18 amps and carries a 24 VAC coil. It fits JP1 and JP3 jockey pump controllers serving larger jockey pump motors that exceed the capacity of the 9 A and 12 A contactors.

Installation is a direct swap: de-energize the controller, transfer the line, load, and coil wiring to the new contactor, then verify the pump starts and stops at its set pressures. Replace any contactor with discolored terminals or contacts that stick — on a pressure-maintenance pump, a welded contact means the motor runs until it fails.

Confirm your controller is a Tornatech JP1 or JP3 and your motor current suits an 18 A contactor before ordering; see CONLOV0001 (9 A) and CONLOV0003 (12 A) for smaller motors.
