Small diameter high lift submersible pump

Small diameter high lift submersible pump and submersible pump technology for organic combination, in the material and pump anti-sand and other aspects of improvement, developed for the small diameter, high head, deep level, deep Large, the displacement of 0.5m3 / h-200m3 / h, head in the 3800m below the high-pressure submersible pump. The pump a number of technology in the domestic leading position, part of the international advanced level, the line became their own characteristics of products.
Taking into account the well water level is higher, deep down, in order to ensure the stability of the pump water supply, to avoid fluctuations in the liquid level caused by pump failure, special matching level control system and frequency control system, Has achieved multi-stage automatic variable speed variable water supply. Reduce the impact of high liquid level on the system and the larger the level of the evacuation caused by the occurrence of the phenomenon, but also played a role in improving the pump efficiency and energy saving.
