Pitless Booster Stations

Water Booster Station Click the image to view full size

The Monitor Pitless Booster Station is a unique device designed for increasing waterline pressure or filling water towers. The Pitless Booster houses a submersible turbine pump, below grade, within a sealed tank reservoir. The Pitless Booster can house pumps up to 30” in diameter.

Monitor Pitless Booster Station Advantages

The Monitor Pitless Booster offers several advantages over conventional pump stations including

  • a smaller footprint
  • elimination of the need for a building or structure
  • elimination of motor noise and no confined space entry


The Pitless Booster offers easy motor service by allowing access from the ground level by lifting our the inner assembly. Units with tank reservoirs 16” diameter or less are constructed using cast (or steel) spool and cast iron discharge bodies. Units with tank reservoirs 18” or larger are fabricated using cold-rolled steel.

Water Booster Station Options Include

  • secondary conduit entry for signal wires
  • wire seals
  • suction and discharge transducer tappings
  • locking caps
