seepex pumps of the BTHE range feature a feed hopper with vertical hopper walls and a ribbon screw rotating centrically and on the edges. This guarantees optimum emptying of the feed hopper and optimised feed for the medium to the conveying elements of the pump. The length of the hopper opening is variable to suit the respective application conditions.
