Amphibious modular pumps

Abstract

“Modular Amphibious Pumps.” The objective of this invention is to provide a modular pump ( 1 ) that can be installed in a series, that has a special volute ( 11 ) and impeller ( 12 ), and that can allow the entry of larger particles without damaging the system.

1 . A modular pump for pumping fluids and suspended solids where the pump comprises a chamber having a center and containing a wet motor having a motor shaft and comprising a volute ( 11 ) and a impeller ( 12 ) with one entrance and at least two exits ( 122 ) and two tabs ( 123 ) with rounded edges. 
   
   
       2 . A modular pump according to  claim 1 , additionally comprising a centrifuge ( 13 ) having a body with orifices ( 131 ) along the body and stationary to the motor shaft. 
   
   
       3 . A modular pump according to  claim 1 , where said motor is displaced away from the center. 
   
   
       4 . A modular pump according to  claim 1 , where the exits ( 122 ) are located transversely to the motor shaft, forcing a centrifugal movement on the fluid.
