Tobee^® ZJ China Slurry Pump is a new generation of centrifugal slurry pumps based on modern hydromechanics and mechanics theories, ZJ series slurry pumps are designed for heavy duty high head applications like ash removal in power plants and mining tailing, 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.

ZJ Slurry pump Design Features:

• 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.
• IMPELLERS - 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.
• CHEMICAL COMPATIBILITY - operating PH range from 5 to 12.
• SEALS - Tobee^® offers 3 kinds of seal options to suit any process requirements.
• GLAND SEAL - The most popular and economical seal option, flush water with certain pressure inject in to packing to prevent slurry from leaking, gland seal is simple, easy to repair and cost less.
• EXPELLER SEAL (CENTRIFUGAL  SEAL) - Rotating expeller generate negative force to prevent slurry from leaking. Use in applications like suction pressure is no more than 10% of discharge pressure, single stage pump, or the first stage of series pumps. Expeller seal need no flush water, do not dilute slurry, seal better than gland seal.
• MECHANICAL SEAL - Suit for high-seal applications such as chemical, food industries that any other materials are forbidden to be mixed into fluid. Cost more and hard to fix.

Tobee^® ZJ High Efficient Slurry Pumps Applications:

Ash Removal

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.

Coal Washing

High head performance could meet the needs of feeding process to filter press, allows the SPL pumps are widely used in coal washing applications.

Mineral Processing

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.

FGD System

Special materials are adopted to resist the abrasion and corrosion from the gas of power generation.

Building Material

The usage of versatile wear/corrosion resistance materials allow the pump could be used in this field to pump corrosive and sticky fluids.

Metallurgy

Specially designed oil lubrication and cooling system ensures the bearings to run at low temperature while delivering high temperature media in steel slag transportation.

Filter Feeding

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.
