Hopper feed pump Type KL-R

The WANGEN progressing cavity pump of type KL-R and the specially designed hopper housing and modular sealing system enable the gentle conveyance of mediums without influencing the structure or quality of such. The low dead space version of the KL-RL series is ideal for use also as a pump in the food industry and particularly easy to clean.
