These pumps consist of a body and impeller assembly with antiabrasion coatings, as on all PEMO pumps, coupled to the heavy-duty waterproof electric fully submersible motor through a coupling cage containing the dual opposed seal with independent permanent lubrication.
These pumps are designed for use in deep wells where a vertical pump would be too costly or impossible to install.
The unique features of the internal coatings give these pumps a broad range of applications: they can pump any kind of liquid or abrasive slurry with up to 30% suspended solids by weight and particle size up to 20mm in diameter.
Pemo Submersed Pumps are installed without masonry or special structures: they can be set on the bottom of the well or hung from a rope, chain or other suspension devices.
A float switch controls the pump, keeping it constantly covered with fluid. Sono inoltre provviste di griglia di aspirazione per evitare l'ingresso di corpi estranei voluminosi che potrebbero intasere i passaggi. An inlet screen keeps out large external bodies and prevent cloggins.
The supplied power cable is 7 metres (23') long or longer if required, very heavy duty, fully insulated and designed for the severest operating conditions.
