G118-1-K31 Lantern Restrictor of 14x12ST-AH Centrifugal Horizontal Slurry Pump Spare Parts.
In slurry pumps, a slurry pump lantern restrictor is located between slurry pump gland packing and slurry pump impeller. It works as a lantern ring, but at the same time has clearances that restrict the flow into the pump. These clearances result in significantly more flush water being required, as there is no longer the interference fit between the ring of gland packing and slurry pump shaft.
By using a lantern restrictor, if the gland flush is always on, at a higher pressure than in the slurry pump wet end parts and the flush water is clean, the packing never encounters slurry and the sleeve and packing life is usually acceptable. Because the sleeve remains in good condition, the leakage is acceptable.
14x12ST-AH Slurry Pump is made for high wearing and heavy duty applications. 14x12 slurry pumps and replacement parts are used worldwide industries like mining, mineral processing, power generation, aggregate processing, or any type of slurry pumping system. It is especially for handling the toughest and most abrasive applications.
Design Features:
Power End
√ Labyrinth bearing isolators to protect internal components during wash-down cycles.
√ Clearances can be easily adjusted to maintain efficiency while optimizing performance and extending wear life.
√ Over-sized, self-aligning spherical roller bearings for trouble free operation.
√ Heavy duty bearing assembly, 50,000 hour minimum L10 bearing life, Distortion free bearing clamp system ensures maximum bearing life and prevents premature fatigue.
Wet End
√ Maintenance friendly split casing for elastomer liners (lined wet end).
√ Static vanes reduce wear and prevent erosion.
√ Tangential discharge improves efficiency and reduces wear.
√ Optimized hydraulics for high efficiency and low wear.
√ Dowel pins for easy and accurate split case alignment (lined wet end).
√ Ribs designed for optimized strength/weight.
√ Static suction vanes extend wear life (metal wet end).
√ Patented flange system for ease of maintenance (metal wet end).
√ Adjustable suction cover on sizes 200 and larger to optimize efficiency and minimize wear.
Sealing arrangements:
√ Packed gland with expeller configuration (other sealing options available).
√ Split stuffing box for simplified installation and adjustments.
√ Mating shaft sleeves with engineered materials for extended life.
Tobee 14/12 ST AH Slurry Pumps Applications:
The 14/12 ST AH Slurry Pumps are widely used to transport high-hardness, strong-corrosion and high-concentration liquids that contain suspended solid particles, such as finished ores, refuse ores, ashes, cinders, cements, mud, mineral stones, lime and etc. in the industries of metallurgy, mining, coal, power, building material and etc. The temperature of the pumped solid-liquid mixture should be ≤80℃, and the weight concentration should be ≤60.
