ZOELLER SUMP PUMP BUYER'S GUIDE

Zoeller sumps are all characterized by rugged construction, excellent engineering and consistent performance. In addition to performing standard basement sump applications, most of these pumps can be used for general dewatering and effluent applications as well.

The Zoeller 49 Water Ridd’r III pumps are submersible dewatering pumps. The pump itself is made of rugged cast iron with a baked-on enamel finish for corrosion resistance, while the base and pump housing are constructed of glass-filled polypropylene with no screen. A non-clog vortex impeller made of engineered glass-filled thermoplastic (with a metal insert) allows the pump to pass ⅜” spherical solids. The Water Ridd’r III 49 models are lightweight (11 lbs.) and compact about (9” x 10-½”) making them ideal choices for dewatering applications in confined spaces or if you want an easily portable dewatering pump.

Zoeller’s Aqua-Mate pumps are reliable and versatile pumps built for dewatering in residential or light commercial applications. Thermoplastic Aqua-Mate models come are built with noncorrosive engineered plastic pump housing, motor housing and base. The plastic construction and lack of steel sheet metal prevents the pumps from accruing rust over time (some components, such as the screws are stainless steel). “Builder” type Aqua-Mate pumps (73 and 75 models) are constructed of rugged cast iron with a baked on enamel finish for increased corrosion-resistance. Builder pumps also feature a heat sink to dissipate the motor heat. Regardless of construction type, each Aqua-Mate pump has been factory tested to be completely submersible and is also hermetically sealed to be watertight and dust tight. Thermal overload protection is also included on each model. If you want consistent and worry-free dewatering operation, the Aqua-Mate series may be for you.
