1 HP Variable Speed 2 in. Threaded Ports CaliMar Pool Pump, 230V

The CaliMar CMARVSP1.0 is a 1 HP variable speed pump built for inground pools, spas, water features and fountains. Thick walled body castings, engineered hydraulics and a heavy duty totally enclosed fan cooled motor are what let it run a full season on a pad that sees sun, rain and chlorine.

Why variable speed matters

A single speed pump moves water at one rate whether you are filtering overnight or vacuuming. This one runs anywhere from 450 to 3450 RPM, so filtration happens slowly and quietly for most of the day and full speed is reserved for cleaning and backwashing. Moving the same water more slowly uses far less power, which is why the pump carries a WEF rating of 7.5 and is listed under ENERGY STAR 2.0. That listing is also what most utility rebate programs are written against.

Built to stay serviceable

The permanent magnet motor produces less noise and vibration than the induction motors it replaces. Wetted components are molded from corrosion proof reinforced thermoplastic, the shaft is stainless steel and the mechanical seal uses American designed carbon to ceramic sealing faces. A large strainer basket sits under a clear engineered polymer lid that stays transparent instead of clouding, and the lid locks with a quarter turn, so checking the basket is a ten second job rather than a tool job.

Before you order

This model is specified at 230V single phase, 10A, so confirm the circuit at the pump pad is 230V. Suction and discharge are 2 in. threaded ports, the standard size on inground systems. The pump is self priming and carries a NEMA Type 3 environmental rating for outdoor installation.
