Cal Pump waterfall pumps are solidly constructed with non-corrosive components, ceramic mechanical seal and brass insert in the 1 1/4" discharge. Their water-cooled design ensures safe and efficient operation without fear of harm to ornamental fish or aquatic plants. The Cal Pump submersible pump is great for high volume waterfall applications, skimmers, powering large Bio Filters, Steams, Aeration and more.
1 1/4" up to 2" MPNT adapter included on PW2500 through PW5500.
Can always use extra fittings for 1 1/2" Tubing.

Note: If excessive buildup of debri cloggs the screen on the bottom of the PW waterfall pump you can use the 1 1/2" filter screen underneath the PW Pump. Ask for details.
