The Marathon Petroleum Refinery in Robinson, IL needed this new industrial process water pump station to handle its medium flows of highly acidic water combined with standard wastewater. A precast concrete sump included an interior Tnemec coating to withstand the water chemistry from a refinery testing lab. 11 hp Goulds grinder pumps were designed in a duplex configuration and included a factory epoxy coating to withstand the water chemistry. The pump station piping was designed with stainless steel components, and corrosion resistant floats were included as the liquid level sensing devices.

A large neighborhood received these two lift stations that were designed to handle medium sewage flow requirements. The submersible solids-handling pumps in duplex configurations were specified to handle influent from three inlet lines from different sections of the neighborhood. The below-grade valve assemblies hold the system operation valves, bypass pumping ports, and shut-off valves. The outdoor UL listed control panels utilize pressure transducers and redundant float controls for liquid level-sensing; basic alarms were included for communications.

A liquid hydrogen plant required this large 20’ deep lift station to handle super-high flows of industrial wastewater. In order to provide redundancy and expanded pumping capabilities, triplex submersible centrifugal pumps were specified in the 8’ diameter sump. A large custom valve vault holds the complete 8” valve configurations with triplex discharge piping and force main headers. Two below grade junction boxes hold electrical disconnects to comply with the classified space. An outdoor UL listed control panel uses float controls for primary and backup liquid level-sensing.

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.

These package lift stations were designed to meet the high head pumping requirements for this training facility of the US Army Corps of Engineers. For one station with over 7,000 ft. of 8” force main, 35 hp duplex submersible centrifugal pumps were supplied to achieve the 300 gpm flow rate . The second lift station used smaller, 4 hp duplex grinder pumps to meet its pumping requirements. Outdoor UL listed control panels utilize float controls for level-sensing and soft starters to provide advanced pump diagnostics and to reduce inrush currents. Autodialers were specified for communications.
