This represents the cheapest & most user friendly pumping station design. The pump is installed directly at the bottom of the wet pit using our automatic coupling system. This system ensures that the pump is properly lowered (& firmly connected to the discharge piping) or Lifted out (disengaged from line) in a simple, precise & quick way. This system includes guide rails (which guide the pump correctly downwards) till its discharge flange matches that of the auto coupling pedestal. The contacting surfaces are well machined & designed such that the weight of the pump compresses an inbuilt rubber bellow gasket to ensure a leak free joint. The pump is kept in place by its own weight - there is no need for any fasteners to clamp it to the delivery piping. Removing the pump for maintenance is equally simple – just pull it up; there are no bolts to be dismantled. The operator need not enter the septic sump once the automatic coupling system is fitted.

Minimum Liquid Level
If site conditions dictate minimal depth of excavation (& hence a higher sump bottom level ); Jacket cooled motors can be (optionally) offered allowing the pumping to almost the casing level of the pump. Aqua’s wet pit jacket cooling system is field proven to be clog resistant in densely polluted sewage. It uses the pumped media to dissipate motor heat & hence does not require any additional coolant / impellers.

We do offer an option of close circuited jacket cooling systems (utilizing special coolant& internal circulation impeller) for cases where the pumped liquid is very corrosive or very thick.

 

Temporary submerged installation

Certain applications like sewer pipe line construction / maintenance works, salvaging flooded dry pits in pumping stations, replacing aged dry installed pumps (by mounting the ANS pump directly in the wet pit), drainage of open sewer drains; require submersible pumps to be installed on transportable portable stands. ANS pumps can be factory fitted with portable skirt base stands enabling quick & versatile installation - they can be fitted either Vertically or Horizontally.
