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 exported 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.

Installation method

1. Mobile hard pipe installation

The pump is supported by its base, and the hard pipe joint is connected to the pipeline system.

2. Mobile hose installation

The pump is supported by its base, and the hose connector is connected with the water outlet hose. It is multi-purpose and easy to install. The pump can be easily moved from one sewage well to another.

3. Fixed dry installation
Can withstand flooding, for wet/dry well or pipeline connection of the pump system, suction port and drain port a flange and pipe connection, vertical installation. If this installation is selected, it must be equipped with a cooling system.
4. Fixed wet installation
The pump is supported by a base and fixed at the bottom of the sewage well. The drain port is connected with the pipeline. The vertical installation water outlet hose is connected. It is multi-purpose and easy to install. The pump can be easily moved from one sewage well to another.
