140 Series Effluent Pumps

• ZOELLER BN-140 (BN140; STF-100-FILTER)

The 140 Series Effluent Pumps from Zoeller Pump Company come with a durable, cast iron construction. This model works well in light commercial applications and is a desirable choice for homeowners prioritizing longevity.

An effluent or dewatering pump moves grey water containing limited solids, such as some septic fluids, laundry water, and other waste liquids. Depending on your chosen model, the pump system can pass ¼- to ½-inch spherical solids, and both have a 1 ½-inch vertical discharge. A single-vane impeller design uses centrifugal force to push fluid against the pump volute, keeping it away from the impeller vanes for smooth, clog-resistant operation.

These fully submersible models come hermetically sealed to prevent dust and water incursion. A finish consisting of powder-coated epoxy prevents corrosion, and heat dissipation technology in the motor helps provide a long service life. You can choose various level control systems and container sizing for longer cycles.
