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.
