Lift stations are facilities which are utilized in municipal and industrial water management and treatment, and mining applications. These stations utilize gravity conveyance to move water from lower to higher elevations, and direct the flow of water, wastewater or storm drainage often in low lying municipalities with flooding potential.
Key elements of lift stations include a wastewater receiving well or wet well with a screen (to remove particulate materials), submersible pumps and piping with valves, motors, and an equipment control and alarm system.
Due to the viscous and corrosive quality of the wastewater, storm water and sewage that is processed through a lift station, these systems require material compatibility with harsh media. Submersible pumps at the bottom of lift station storage tank are designed to pump suspended solids, sewage and slurry.
Electronic pressure & level measurement is often used to identify blockages, back-ups and flooding. During pump staging, this indication can trigger alarms to turn on additional pumps in flood situations, equalize pump wear, and turn pumps off when tank levels are low.
NOSHOK offers several submersible pressure & level measurement solutions to address these applications. Our 612 Series submersible transmitter features corrosion-resistant, stainless steel construction, and provides highly accurate, shock resistant and extremely stable performance over long periods of time. This sensor incorporates an advanced diffused semi-conductor and sputtered thin film sensor for maximum stability.
NOSHOK also offers an anti-clogging 613 Series cage-protected submersible transmitter for use in severe high solids environments such as sewage, lift stations, storm canals, wet wells and slurry tanks where sludge, slurry or turbulence may be present. This transmitter features durable all 316 stainless steel construction and a large 2.14” diameter diaphragm which is extremely responsive, even when monitoring very low liquid levels or when buried in viscous media. The NOSHOK 613 Series transmitter is welded at the cap and base to provide a leak-tight seal and features a standard 1/2" NPT conduit for attaching lifting rings or mounting brackets.
The NOSHOK Type 40 flow-through annular style diaphragm seal can be incorporated into the piping at the pump to offer a non-clogging seal, along with the NOSHOK 800/810 Series electronic indicating pressure transmitter/switch to provide feedback and alarms to the control panel. This system can warn the user of a high or low pressure situation that could damage pump(s) at the station.
