Batescrew Axial Flow Pumps.
Vertical Application - Description.

The traditional vertical pump, as seen here, is most often used for pumping from sumps of one type or another.  Cost is less than for an equivalent angle application pump.
Vertical pumps are also used for pumping from open water e.g. rivers, dams, channels etc., with appropriate supporting structure.  (For these open-water situations, an angle application pump is often more appropriate, due to lower installation costs.)
If the depth of a sump exceeds six metres, excavation costs become excessive.  In some cases a different system layout will allow the use of a more cost-effective angle application pump.
Mounting Plates are normally bolted immediately below the discharge head flange, as seen at left, and allow the pump to be rotated in one hole increments, if necessary,  for alignment of the discharge.  See below for mounting details of below-ground discharge.

 On pumps with discharge below ground level, mounting plates may be located at any of the four alternate positions indicated at left..  Please specify the preferred location when ordering.




This combination of sump cap and swivel-mount allows for pumping from a dam or channel with a water level higher than the pump site, it also permits unrestricted rotation of the pump for alignment.
The fabricated steel cap is machined to take the rubber sealing ring and is hot dip galvanised.  The hole in the cap is of sufficient diameter to allow removal of the pump without removing the cap.
