For the operation of a mix shield a bentonite suspension is mixed in a container. A pump circulates the mixture via a pipe circuit. Bentonite is added via a venturi nozzle on the pipe. Very heavy wear due to bentonite.
1x KTZ45.5 for 24h continuous operation. This pump has been running since July 2001 without breakdowns and without any visible wear.
