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 pump station was configured to meet the medium flow requirements for this clean water power generation process and reuse system. The system has a large precast-concrete rectangular sump with a barrier wall –or weir wall- to reduce turbulence for the pumps.
To create new potable water, this lift station pumps clean stormwater from a collection/storage basin to a treatment facility. Duplex vertical turbine pumps move high flows of water very efficiently and use soft starters to reduce torque on the vertical shaft and provide additional pump diagnostics. Also included is an above-grade valve assembly on the top slab. The control panel utilizes an ultrasonic transducer for primary level controls and a pressure transducer for backup. The entire package lift station is located inside an owner-supplied control building.
