50ZJ-I-A50 Horizontal Slurry Pump

50ZJ-I-A50 Horizontal Slurry Pump is horizontal, axial-suction, single-state, single-suction and centrifugal slurry pump. The series pumps, through combination of advantages of similar products both at home and abroad and innovation in the aspects of hydraulic design, structural design and materials of flow passage components, own the features of high efficiency, energy conservation, small vibration, low noise, reliable operation, long service life and easy maintenance. The allowed maximum paste weight density of solid-liquid mixture(cw) is 45% of ash paste and coal paste, and 80% of pulp and dense media.

Design Benefits:

• 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.

Tobee^® 50ZJ 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 ZJ 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.
