Stancor Sump & Effluent Pumps

Stancor pumps serve dewatering, wastewater transfer, sump drainage, and solids-handling applications. They are used in industrial facilities, utilities, mining operations, construction projects, and other sites that need dependable liquid removal.

Stancor offers electric submersible dewatering and solids-handling pumps. Product families include P/S dewatering pumps and SE/SV and SEW wastewater pumps, with selection based on the liquid and required performance.

A dewatering pump is selected to remove accumulated water, while a wastewater pump must also accommodate the expected waste and solids. Passage size, impeller design, and material compatibility help determine the appropriate choice.

Selected Stancor wastewater pumps are designed to pass solids. Check the specific model’s allowable particle size and impeller design, especially when the liquid contains fibrous material, grit, or a high solids concentration.

A vortex impeller creates liquid movement that carries material through the pump. This design can help accommodate solids, but the complete pump selection must still account for particle characteristics, flow, and discharge head.

Oil Minder combines compatible submersible pumps with oil- and water-sensing controls. It is intended for applications such as elevator sumps and utility containment areas where water removal must be coordinated with oil detection.

Oil Minder is a sensing and pump-control system, rather than a treatment device that removes oil from water. Oil containment, removal, and any required wastewater treatment must be addressed in the overall installation.

Compatible Stancor pumps can be configured with Oil Minder for elevator-sump applications. The pump, controls, sensing arrangement, and discharge design should be selected for the conditions and requirements of the specific installation.

A simplex system has one pump. A duplex system has two pumps and can be configured for alternating operation, additional capacity, or backup duty. The control strategy should reflect the facility’s actual drainage requirements.

Determine the required flow, total dynamic head, sump dimensions, liquid properties, and solids characteristics. Also confirm available voltage and phase, operating levels, and whether the application requires a single pump or coordinated multiple pumps.

Yes, with suitable controls. Float switches or level sensors can command pumping based on liquid level, while additional monitoring can support alarms. Confirm compatibility among the pump, control panel, and sensing equipment.

Continuous-duty suitability depends on the selected model and installation. Verify cooling requirements, minimum liquid level, maximum liquid temperature, and the allowable operating range before specifying extended or continuous pumping.

Frequent cycling can result from closely spaced start and stop levels, limited usable sump volume, returning discharge water, or an oversized pump. Inspect the controls and system arrangement before replacing the equipment.

Follow the pump and control manuals for inspection and service intervals. Check the intake, wear components, cables, level devices, and alarms, and verify that the complete system responds correctly to changing liquid levels.

A replacement may be possible after comparing performance, solids capacity, dimensions, discharge connections, electrical requirements, and control compatibility. Provide the existing nameplate and installation details so the replacement can be evaluated accurately.
