Series 1522 cast iron centrifugal pumps are reliable, close-coupled, foot-mounted pumps intended to pump water through closed loop systems for hydronic heating and cooling, primarily in commercial settings. These pumps are ideal in applications where front end suction and top discharge is needed. The Series 1522 features a back pull-out design, which allows the pump to be serviced without disturbing system piping. Flexible coupling and large bronze sleeve bearings provide significant noise reduction, making the Series 1522 perfect for installation in locations where quiet operation is critical. The 4T is a three phase pump and includes a bronze impeller, a 2" end suction, and a 1-1/2" top discharge.
