SQGP(B)Q type unattended amphibious submersible sand pump

SQGP(B)Q type gas isolation submersible sand discharge pump adopts a semi-open impeller. The end face of the guide body at the mating surface with the impeller blade is provided with a vent hole. When the impeller enters the gas, the gas will be discharged along the vent hole to realize unattended operation and keep the pump running continuously. The conveyed medium is derived from the outer sleeve of the motor, and the motor is cooled by the conveyed medium, allowing the motor to run without flooding. This series of products have compact structure, convenient use and maintenance, good passability and wide operation range. Suitable for conveying sewage containing gravel and other solid particles.
