Pneumatic Sump Pumps
Pneumatic sump pump, or named as pneumatic submersible pumps are ideal to empty ballast tanks, bilge wells, etc. in emergency cases. Often used for draining cargo holds during and after washing procedure. Especially preferred where an electric spark may risk ignition or explosion. The pumps can also be applied in mining industry.
Product features：
QYW/K type pneumatic blade sewage submersible pump, this series (oil free type) pneumatic water pump is divided into two parts: power and water pump. The power adopts tangential intake blade type aerodynamics. The overflow part of the water pump adopts an efficient spiral vortex chamber, and the two parts are connected as one; The intake adopts tangential compression in the middle of the cylinder, reducing the resistance of the intake airflow and pressure loss. At the same time, it also utilizes the velocity energy of pressure to balance the uniform wear at both ends of the blade, further extending the service life of the blade. Adjusted the structural parameters and intake and exhaust positions of the pneumatic motor, increased the working chamber for the expansion work of the pneumatic motor, and greatly improved the shaft power of the pneumatic motor; The optimization design of matching the power of the pneumatic motor shaft with the water pump makes the configuration more reasonable, and the water pump head has been significantly improved, meeting the needs of a large number of users.
