Mixed flow pump is a kind of pump between centrifugal pump and axial flow pump.
The specific speed of mixed flow pump is higher than centrifugal pump, lower than axial flow pump, generally between 300 and 500.
Its head is higher than the axial flow pump, but the flow is smaller than the axial flow pump, larger than the centrifugal pump.
When the prime motor drives the impeller to rotate, it has both centrifugal force and axial thrust on the liquid, which is a combination of centrifugal pump and axial flow pump, and the liquid slanting out of the impeller.
Therefore, it is a kind of pump between the centrifugal pump and the axial flow pump.
The specific speed of mixed flow pump is higher than centrifugal pump, lower than axial flow pump, generally between 300 and 500.
Its head is higher than the axial flow pump, but the flow is smaller than the axial flow pump, larger than the centrifugal pump.
Range of application
Used to transport clean and contaminated media, chemically neutral or corrosive media.
Forced circulation, seawater culture, urban gas engineering, water treatment system in chemical process.
Design features
The mixed flow pump is a "pull out" structural pump. When inspecting and disassembling the impeller and shaft seal, it is not necessary to disassemble the pipeline connected with the pump body.
Equipped with precision machined pump shaft and bearing with thin oil lubrication, in the stuffing box cover with protective sleeve.
Oil level of bearing box can be controlled by constant oil cup.
The support of the pump body can withstand any load from the pipeline and pass it directly to the foundation.
In this way, the rotor will not bend because the pump is under load, thus ensuring the optimal service life of the bearing.
Because of the large overcurrent area, the congestion is reduced.
The rotation direction of the pump, seen from the driving end, is clockwise.
A motor or an internal combustion engine may be used for power drive.
The pump device can be equipped with a complete air discharge device, conducive to the exhaust of the suction line.
Shaft seal
Packing seal or double end mechanical seal.
The material
Corrosion resistant material.
