A publicly funded greenway project required two package lift stations that were configured to meet the low flow, high head requirements for this park. Grinder pumps in duplex configurations will alternate between starts to reduce wear on the pumps and make time of operation equal.
This packaged pump station was the second of two pump stations supplied for industrial process water and stormwater at two Valero oil refineries. The design criteria specified varying flows which required a duplex pump configuration with an included “jockey” pump to handle the smaller flows.
This was the first of two packaged pump stations needed to handle varying flows of industrial process water and stormwater at a hydrogen refinery. Submersible centrifugal pumps in a duplex configuration also included a submersible “jockey” pump.
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.
This package lift station was designed to meet municipal standards for medium sewage flows at this new commercial complex. The duplex pump configuration and solids-handling pumps provide suitable preventative measures for a reliable and long-term wastewater lift station. The below-grade valve assembly included swing check valves, a pigging port, and flow meters. An on-site permanent generator and sheltered outdoor PLC control panel provide robust and programmable lift station controls. An ultrasonic transducer and a two float backup comprise the liquid level sensing controls.
