(1) Auxiliary impeller shaft seal: The horizontal wear-resistant and corrosion-resistant slurry pump cleverly uses the impeller effect of reverse centrifugal force to effectively prevent slurry leakage and ensure the stable operation of the pump. In a single-stage pump with a positive pressure value at the pump inlet or a first-stage pump with a multi-stage series pressure value of no more than 10% of the pump outlet pressure value, this slurry pump is specially equipped with a secondary impeller shaft seal, which is unique in that it does not require shaft seal water, so as to avoid the slurry being diluted and ensure that the shaft seal effect is excellent. Therefore, under specific working conditions where the slurry cannot be diluted, the horizontal wear-resistant and corrosion-resistant slurry pump can exert excellent performance.
2) Packing shaft seal: As a common sealing method in horizontal wear-resistant and corrosion-resistant slurry pumps, packing shaft seals are widely used for their simple structure, convenient maintenance and economical performance. Although shaft seal water is required, packing shaft seals are ideal in applications where secondary impeller shaft seals are not suitable, ensuring pump reliability and durability.
3) Mechanical seal: The mechanical seal of the horizontal wear-resistant and corrosion-resistant slurry pump is mainly suitable for scenarios with extremely high requirements for sealing, especially in the chemical field, which not only requires that the slurry cannot leak, but also must strictly prevent external substances from entering the pump body. Although mechanical seals have excellent sealing performance, they are expensive and difficult to maintain, so they need to be selected based on a combination of actual needs and operating conditions.
In general, the horizontal wear-resistant and corrosion-resistant slurry pump adapts to the needs of different working conditions through flexible sealing design, ensuring the efficient, stable and reliable operation of the pump.
