The Cal Spas Jet Pump PUM22001600 is a 2-speed, 230-volt replacement jet pump used in compatible Cal Spas hot tubs. This 56-frame pump features 2″ intake and 2″ discharge plumbing connections and is rated for 10 amps on high speed and 3.5 amps on low speed.
This pump is commonly used as a replacement for older discontinued Power Right PRC4212X and 5KCP39TN4212X pump assemblies when electrical and plumbing specifications match.
Common symptoms of a failing spa pump include humming without starting, weak jet pressure, tripped breakers, loud bearings, leaking seals, or complete pump failure.
You will typically reuse your existing pump cord. If your cord is damaged or missing, a new cord is sold separately here: 2-Speed Pump Cord
EZ’s Pro Tip: Replace the gaskets whenever replacing a pump to help prevent leaks during installation — 2″ Flat Pump Gasket
Important: When replacing a spa pump or motor assembly, always match amperage, voltage, speed, frame size, and plumbing size. Horsepower (HP) and brake horsepower (BHP) ratings are often used inconsistently by manufacturers and marketers. Always compare amperage and electrical specifications first to avoid poor performance, nuisance breaker trips, or fire risk.
