VerderGear (made by Kracht) gear pumps are suitable for pumping medium to high viscosity liquids which have a lubricating property. The pumps deliver a constant, non-pulsating flow of fluid which is easily reversible by changing the direction of rotation. The BT / BTH models are slowly running gear pumps for pumping medium to highly viscous fluids of various kinds. The liquids should have to have lubricating properties, to contain no solid particles and not to adversely affect the materials of the chemical pump. The pumps of the BT series are standard suitable for ATEX Zone 2 (3G) and ATEX Zone 1. The pumps can be used for pumping grease, molasses, finasse, chocolate and paint and ink products.
