Davey Clean and Grey Water Drainage Pumps

Davey Clean and Grey Water Drainage Pumps are double case submersible pumps that stay cool when not completely submerged. The double case allows for full water flow around the pump motor for superior cooling and a longer pump life. Double case pumps are capable of pumping clean water with a maximum of 10% small soft organic solids.  Diameter of less than 10mm. Water should be of a neutral pH.  Some accelerated wear is expected when pumping hard solids in suspension.
