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.

Pleasant Valley RV Park

Pleasant Valley RV Park|Williston, ND|844 GPM - 38' TDH

jweddell500gpm - 1,000gpm, Central, Mixed Use Development, Resorts/ Golf Courses, Wastewater

A residential boom town of employees from nearby natural gas mining facilities needed a large lift station to handle over 1.2 MGD of wastewater. Submersible Ebara sewage pumps in a triplex configuration were included for the new and future pumping rates resulting from residential growth. The lift station controls are located in a nearby control building. The UL listed control panel utilizes floats for primary and backup level controls, an autodialer for communications, and a permanent onsite generator for backup power.

Gas Refinery Process Water

Exxon Mobil|Chalmette, LA|30,000 GPM - Various TDH

jweddell10,000gpm +, Central, Stormwater, Stormwater Runoff

To address the industrial stormwater concerns of coastal Louisiana, this large, precast concrete pump station was designed to meet super-high flows of runoff at this Exxon refinery. Five vertical turbine pumps and three submersible pumps, capable of pumping 60,000 GPM, are spread across three large interconnected rectangular wet wells. This approach was much more affordable than a single poured in place sump, and the connection tubes make the functionality near identical. A robust steel baffle slows incoming stormwater at the inlet line to reduce turbulence and wear on the sump components.

Groton Power Plant|Groton, SD|130 GPM - 45' TDH

jweddell100gpm - 300gpm, Central, High Temperatures, HRSG Blowdown, HRSG Pumping, Industrial, Industrial Water, Power Generation, Process Water

The Groton Generating Station needed this package lift station to pump clean water as a part of its power generating processes from natural gas. The submersible centrifugal pumps in a duplex configuration meet the pumping requirements for this facility and discharge the water to parallel force mains.
