Unusually high service factors enable the assembly to carry all radial and axial thrusts. A rigid large diameter shaft with reduced overhang minimises deflection and vibration under all conditions ensuring trouble free operation. √ Tobee heavy-duty grease lubricated taper roller bearing assemblies are fitted as standard. (Except the 6/4 DG which has two components) Gold can hide down in the deepest part of a crack or crevice or behind a boulder and often is best reached with a hand dredge, also called a 'sucker gun' or 'suction gun.' This gold prospecting tool is ideal for working below the water line when a motorized dredge cannot be used.
The casing is made up of three components to reduce maintenance time and costs associated with a onepiece design. √ The large, robust casing has been designed to reduce internal velocities resulting in minimum efficiency loss and improved casing wear life. The unique casing design and sealing vanes prevent abrasive solids intrusion at the sealing faces. √ Specially designed and shaped impeller vanes allow the handling of extraordinarily large particles. Efficiency is maintained by minimising suction side recirculation. √ Impeller expulsion vanes reduce gland pressure and intrusion of high concentrations of solids in the gland area. √ The unique segmented clamp ring on larger size units and solid on smaller pumps, facilitates casing rotation to any angle, reducing the need for costly high wearing bends.
