Liberty's SPAC-S37-ALM-P1 is a factory-assembled SPAC-Series sump pump package. A 1/3 HP Model S37 sump pump sits in a durable structural-foam pit (18" x 22" basin, 22-1/2" overall height) with a gasket-sealed, radon-ready polyethylene cover, pre-assembled with 1-1/2" Schedule 40 PVC discharge piping. A molded pump platform raises the pump off the bottom of the pit, secures it during shipping, and is sized to also locate a Liberty 441 or 442 battery backup pump. Two 4" inlet hubs with rubber grommet seals are provided. Wired for 115V, with a 10' cord. Ships with a Liberty ALM-P1 standard alarm. Shipping weight approximately 26 lb.
