PRODUCT INTRODUCTION
QD/Q series multi- -stage submersible pump(here in after referred to as the electric pumps).The electric pump is composed of water pump. motor and mechanical seal, located in the upper of electric pump, motor is single or three- phase asynchronous motor; located in the lower part of electric pump, water pump of channel impeller or vortex impeller volute structure, mechanical seal and framework oil seal are adopted between water pump and motor as seal, 0- shaped oil resistant rubber seal rings are adopted at fixed rabbet seals as static seal to insure the rlibility of electric pump.

PRODUCT USAGE
This series of electric pumps are widely used in such fields as industry agriculture, mining, building construction and municipal administration and environmental protection.
