MERCK Animal Health Variable Water Chemistry Pump

Merck Animal Health|DeSoto, KS|100 GPM - 21' TDH

jweddell50gpm - 100gpm, Central, Corrosive/ Caustic Pumping, Industrial, Industrial Process Water featured, Pharmaceutical Waste

This industrial pumping system was designed to handle medium flows of process wastewater created from cleaning cycles at the Merck Animal Health facility. The wastewater was specified with highly variable pH conditions, so the pumping system was designed with a double-wall fiberglass sump with leak detection. All of the submersible components in the well were constructed of stainless steel, including the Tsurumi duplex submersible pumps. The pumping system electrical controls comprised a UL listed panel with SCADA integration.

TVA Power Plant|West Paducah, KY|50 GPM - 67.7' TDH

jweddell50gpm - 100gpm, Central, Industrial, Industrial Water, Power Generation, Wastewater, Wastewater Featured

This industrial power plant needed a package lift station to meet the requirements for municipal wastewater. The 23-foot-deep sump holds duplex Goulds submersible sewage pumps specified to meet the 50 gpm maximum flow requirements. A precast concrete valve vault contains the system valves and a force main junction. Both the below-grade wet well and valve vault are pedestrian rated. Liquid level-sensing controls are a pressure transducer and floats for backup. The outdoor control panel includes a receptacle for an owner supplied onsite generator.

Tesoro Oil and Water Separator Pump

A remote Tesoro Corporation industrial site needed this stormwater pump station to handle water discharged from an oil/water separator which processes on-site runoff. Submersible centrifugal pumps were used in a duplex configuration in this shallow wet well. The 7.5 hp Ebara explosion-proof pumps were sized to meet low flow, medium head conditions for stormwater. Check valves and plug valves were integrated into the discharge piping in the well for a simple and cost-effective design. The precast concrete wet well and the access hatch are both pedestrian rated.

This power generation facility installed a package lift station designed for medium sewage flows of industrial wastewater. To protect the submersible solids-handling pumps, an inlet line deflector panel was included in the design. The wet well was protected from off-gassing and corrosion by an interlocking fiberglass lining. Conductive probes are used for primary and backup liquid level-sensing with an outdoor UL listed control panel. The panel is outfitted with a basic alarm and an autodialer for telecommunications.

Industrial Stormwater Pump Station

British Petroleum Refinery|Bellevue, WA|350 GPM - 30' TDH

jweddell300gpm - 500gpm, Industrial, Industrial Process Water featured, Oil & Gas, Oil/Water Separators, Pacific, Stormwater, Stormwater Runoff

This package lift station handles the medium flows of stormwater and process water drainage at this oil refinery. A stormwater plan is required at most industrial facilities and BP proactively chose a reliable lift station to manage its environmental footprint. Duplex submersible centrifugal pumps and a below grade valve assembly comprise the major underground components of this system. An outdoor control panel utilizes float controls and an ultrasonic transducer for primary and backup liquid level-sensing.
