The Goulds WE0511H is an excellent choice if you are looking for an Effluent Pump. This pump can move effluent (or graywater) in residential or light commercial settings. It was specifically designed for on-site wastewater treatment in multi-unit dwellings with expansive systems.

Think farms, trailer parks, motels, schools and hospitals. Basically, any site that involves a large number of people using the system everyday. The Goulds WE0511H Effluent Pump can transport effluent containing up to ¾” non abrasive solids. It is a heavy duty pump at approximately 70 lbs.

Construction

Goulds Effluent Pumps are known for sturdy, well-designed construction and this model is no exception. The volute is rugged class 30 gray cast iron for extra protection. Specifically, the cast iron is thick enough to withstand 1.5 times (!) the shut-off pressure that could potentially be produced by the largest available impeller for the pump. Now that’s rugged.

The shaft is stainless steel with a threaded design and the fasteners are 300 series stainless steel. The cast iron impeller is a semi-open type with pump out vanes that distribute potential contaminants to prevent clogging. The mechanical seal has two sealing silicon carbide faces and BUNA-N elastomers for containment.

Extra special construction is particularly important for submersible effluent pumps because of the potentially corrosive effects of being submerged in and pumping out wastewater for extended periods of time. The construction of the Goulds WE0511H Effluent Pump ensures that the pump will avoid damage and perform for the life of the pump. In fact, while the pump is meant to be run continuously submerged, it can also be run dry for intermittent periods.

Naturally, such a pump will need to be able to withstand certain temperatures and the Goulds WE0511H can withstand continuous water temperatures up to 104° F.
