Tobee® China ZJ High Efficient Slurry Pump is a new generation of centrifugal slurry pumps based on modern hydromechanics and mechanics theories, TJ series slurry pumps are designed for heavy duty high head applications like ash removal in power plants, coal, Filter press feed and mining tailing etc, oil lubrication with water-cooling design makes the bearings always working at lower temperature, direct connected drive are always optional by trimming impeller to appropriate diameter and to get performance just in need, save the cost for variable-frequency motor. Specially designed liners and impellers structure help pump get higher efficiency and high head.
√ Single stage, single suction, overhang shaft, centrifugal, double casing, hard metal horizontal slurry pump design.
√ Base - A single piece base with integrated adjustment mechanism for impeller clearance within pump, bearing assembly locks into base using six or eight heavy-duty bolts.
√ Bearing assembly - all bearings assembled with highest quality tapered roller bearings in controlled environments to prevent lubricant and housing contamination, oversized shaft diameters and reduced overhang in the wetted end contribute to long life and reliability in the field
√ Impeller - hard metal impeller, pump out vanes on rear and front reduce recirculation within pump, and aid in preventing seal contamination, optional castings of straight or semi-Francis vanes offer wider hydraulic options in single sizes
√ Liners - heavy-duty hard metal liner, active engineered attachment mechanism to casing via threaded bolts as opposed to unreliable glue
√ Throatbush - adjustable via cotters to account for wear over time and increase efficiency
√ Expeller seal combined with packing seal and mechanical seal have been adopted to guarantee the slurry from leakage.
Tobee® TJ High Efficient Slurry Pumps Applications:
Featured with high efficiency and high head, hard metal wet parts, plus the usage of oil lubrication bearing assembly, ensures the pump could running continuously without stop in ash removal in power plants.
High head performance could meet the needs of feeding process to filter press, allows the SPL pumps are widely used in coal washing applications.
The rigid structure design and usage of wear-resistance hard metals, combined with low running speed, allows SPL slurry pumps could be used in long distance tailing transportation.
Special materials are adopted to resist the abrasion and corrosion from the gas of power generation.
The usage of versatile wear/corrosion resistance materials allow the pump could be used in this field to pump corrosive and sticky fluids.
Specially designed oil lubrication and cooling system ensures the bearings to run at low temperature while delivering high temperature media in steel slag transportation.
Passage of wet part were designed to have the feature that head drops quickly when flow rate increases, by the rule of power consumption: the power is directly proportional to the product of the flow rate and head, and the curves are nearly reverse 45 degree, this means, the power won’t change much when flow rate or head change, this characteristic especially applies to filter-press feeding applications in coal preparation plants, where the flow rate need to be substantial under lower head, and minor flow rate at high head.
