TZG(H) Gravel Sand Slurry Pump
Type TZG(H) gravel pumps are designed for continously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by common pump.They are suitable for delivering slurries in Mining, Explosive sludge in metal melting.Dredging in dredger and course of rivers, and other fields.Type TZ(G)H pumps are of high head ones.
Construction of this pump is of single casing connected by means of clamp bands and wide wet passage.The wet parts are made of Ni-hard and high chromium abrasion-resistance alloys.The discharge direction of pump can be oriented in any direction of 360 degree.This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion-resistance.
Design Features:
• 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. Minimal maintenance is required.
• Impeller expulsion vanes reduce gland pressure and intrusion of high concentrations of solids in the gland area. Efficiency is maintained by minimising suction side recirculation.
• Specially designed and shaped impeller vanes allow the handling of extraordinarily large particles. The unique casing design and sealing vanes prevent abrasive solids intrusion at the sealing faces.
• The large, robust casing has been designed to reduce internal velocities resulting in minimum efficiency loss and improved casing wear life. The casing is made up of three components to reduce maintenance time and costs associated with a onepiece design.
• BODA heavy-duty grease lubricated taper roller bearing assemblies are fitted as standard. A rigid large diameter shaft with reduced overhang minimises deflection and vibration under all conditions ensuring trouble free operation. Unusually high service factors enable the assembly to carry all radial and axial thrusts.
• A unique “-10” (dash 10) end cover assembly comprising of V-seals, double piston rings and an external flinger with grease lubricated labyrinths are standard with all BODA pump.
