Between-the-bearings Design: Impeller is mounted on a shaft supported by bearings on both sides, ensuring stability.
Double-suction Impeller: Dramatically reduces loads on the bearings compared to single-suction types. High-precision casting ensures performance.
Sealing Solutions:
• Packing Seals: Traditional rope-like materials wrapping the shaft, cost-effective for standard applications.
• Mechanical Seals: Highly durable, designed to eliminate leakage in critical environments.
Flexible Couplings: Accommodate vibrations and thermal expansion. We use wear-resisting disc couplings or pin couplings to protect the shaft and bearings from premature wear.
This product is widely utilized across multiple industries:
Professional Cooperation: Long-term relationships have been established with major pump-testing institutions, including National Quality Supervision centers and specialized Irrigation Machinery inspection centers to ensure consistent product quality.
