Large amount of suction lift - is this possible?
Large amount of suction lift - is this possible?
(OP)
Hello, We currently have a submerged multi-stage centri pump ~60m down a borehole pumping water in underground (~5m below surface) tanks. The water has a high Iron content and as a result, bacteria have caused havoc with the resulting rusty slime reducing the throughput of the system. A lack of maintenance is mostly to blame for the drop in pumping capacity, and subsequent 'quick fixes' by the maintenance team have been ill-informed and have made my job somewhat more difficult.
I would like to replace the submerged pump with one mounted on the surface, for easy access by our mechanics. This would require a suction lift of ~60m. Is it possible to achieve this amount lift? even with manual priming?
My aim is to provide a solution of both an easily accessible pump which can deliver the water at a high velocity, to try to reduce the biofouling on the line. If a pump with ~60m of suction doesn't exist, can you think of another option?
Thanks
V

In addition, moving the pump motor to the surface is not going to stop the slime problem. In order to eliminate the slime problem, you will have to periodically disinfect the well. Some wells have the capability to feed chlorine into the well bottom continuously by installing a chlorine feed line attached to the well string.
Shock chlorination/hydrochloric acid treatment should be done only periodically, maybe annually. The well is flushed to waste after these treatments, so I don't understand why it should be affecting your process.
Addition of a multimedia filter will dramatically improve the water quality.

Watch out though, it does not have any persistence.
