McKINNON
Colmena Pump is a multi purpose non-clog type pump designed for
use with water to raise coffee to a certain height and also to transport
it horizontally.
The open faced bronze impeller has been designed to
combat damage during pumping. The blade profile ensures that the
beans in gelatinous condition have smooth entry and exit from the
pump. The pump is used with 50% solids and 50% water condition.
