Polder Type Submersible Pump

Polder Type Submersible Pump

• Jasco Polder type submersible pump is a robustly constructed pump that has a computer aided design. This compact and efficient pump at minimum power output gives optimum output. There are many features of this pump which makes it highly regarding type in the market, for instance continuous operation, no pump housing required, suction from bottom, and drawing of water to lowest level. The wetted parts undergo special anti-corrosive process to enhance their life.
