High tensile gray iron pump bodies
Large water cavities provide fast, easy priming. Separate priming ports enable quick water fill and the fast evacuation of air. Separate 1/4″ tapping’s are provided for the convenient mounting of pressure/vacuum gauges and the pressure switch, and for pump draining.

Buna-n Square cut ring
Reusable provides a positive seal between the pump case
and motor bracket.

Molded diffusers
Corrosion and abrasion resistant, provide precision alignment with the impeller for maximum performance. The snap- in diffuser design uses no bolts and is held in place by compression.

Impellers –
Precision balanced, these impellers are ultra-smooth for high efficiency. 1/3 through 1 HP CPJ, CPH, and EK models feature molded thermoplastic impellers. 1-1/2 HP CPJ models feature brass impellers.

Pipe plugs and priming plugs
Coated with a non-hardening, non-toxic, non-corrosive material which allows for easy removal even after the pump has been in service for years.

Standard shaft seal
Silicon carbide face is self-adjusting throughout the seal life. One size fits all models.

CPH and EK Patented uni-frame motor bracket
Unique to the water systems industry-designed to accept any NEMA J motor if motor replacement is ever necessary.

Automatic overload
Senses both start and run winding heat to ensure complete winding protection.

CPJ models
Feature NEMA J motors. All motors are dual voltage, capacitor start with automatic thermal overload protection.
