SLQS series single stage dual suction split casing powerful self suction centrifugal pump is a patent product developed in this Co.for helping users to settle the difficult problem in the installation of pipeline engineering and equipped with a self suction device on the basis of the original dual suction pump to make the pump to have the exhaust and water-suction capacity. AS of the existing centrifugal pump unit, the user has to do one of the three jobs below when to get the pump suck and start working: 1.mount a foot valve on the water suction pool of the inlet pipeline and close it before starting the pump, then open it when the pump is full of water inside and the air inside is completely exhausted. Under-liquid installation of the foot valve makes overhaul very unconvenient in case of a failure. 2.equip the pump unit with a vacuum pump to lead the water in the suction pool into the pump. Different norms of the pump unit need different norms of the vacuum pump, requiring a cost not low and thus increasing the engineering cost. 3.mount the pump unit under the sucked in liquid surface, i.e. Inverse pumping, that means the basis of the pump room must be below the ground, i.e. digging hole underground, this makes the engineering cost greatly increased. While the powerful self-suction centrifugal pump can make it satisfied for a user to have the pump normally pumping without use of any of the three ways above-mentioned!

Vacuum status all the time and can extract air at any time. 4.Automatic exhaust and water suction is available in case
of water cut-off in the inlet pipeline or requiring to start the pump often. 5.Two structures of single and double air rooms can be set up upon the size of the inlet pipeline and the pump, that means the quantity of air. 6.Not to change the construction of dual-suction pump. The working principle of the pump refer to working principle drawing.
1.Can control the pump unit automatically. 2.Both pump and self suction device use one shaft, no shaft
power is increased. 3.Upon the self suction device, the pump’s inlet is in a
