It’s an obvious fact: safe and clean pumping is better than dangerous and messy pumping. But if you want more proof, here’s a quick look at what makes S&L EVERLAST™ Wet Well Mounted Pump Stations superior to submersible pumps.
Confined Space
– Eliminates the need to enter confined space for maintenance or operation.
– Eliminates the need for a valve vault.
Pathogen Exposure
– Exposure to pathogens is limited with S&L stations.
– Release the vacuum & wastewater falls back into the wet well, un-screw 4 bolts, hang the rotating assembly from the lifting stanchion to access the mechanical seal.
Footprint
– Control panel and valves are located under the enclosure.
– No valve vault is required.
Valve Vault
– No valve vault needed – all discharge valves come preassembled and tested at the factory, under the hood.
– All maintenance & inspection of valves done at-grade.
Fewer Priming Mechanisms
– Submersibles require the following to be primed:
– placement inside wet well at bottom of the wastewater
– explosion proof motor
– oil filled motor
– cables & connections rated for hazardous area
– 316SS rails
– coupling underwater
– seal leak sensor
– motor overheat sensor
– oil filled seal
– S&L stations require the following for priming:
– WaveStart™ Prime Sensing System
– solenoid valve
– vacuum pump
– vacuum tubing
Long Life
– S&L pumps last 25+ years with regular lubrication and general maintenance.
– Design life of the S&L mechanical seal is 7 years.
Maintenance Savings & Safety
– Roughly $2400/yr savings per station over submersible stations for annual maintenance costs.
– Maintenance can be done above grade, eliminating the need for 3 people on site, paperwork, and time for confined space entry maintenance and inspection.
