Here is the DM tranfert pump. Powered by an electric motor and available from 6 to 12 feet. Completely galvanised, it will perform its task for several years without any hassles. The electric motor ( 5hp - 7.5hp) transmit the rotation to the impeller at the bottom of the pump with 2 straps and a steel shaft.
No bearing or oil bath that rust into the manure! Only prediodic greasable sleeve. Much more enduring. A mixing kit is also available in option ( include rotating nozzle and pivoting trap)
The impeller is equiped of many knives and can pump up to 900 US gal. per minute. A 12in impeller is also available for a higher flowrate.
