Axial flow pump

Axial pump impeller is open, generally 2-6 leaves. Leaf blade streamlined, leaf twisted, like propeller. When the impeller rotates, it will push the water so that the water in the tube flows out of the axis. Impeller blades according to its installation angle can be divided into fixed, semi-adjustable and all three adjustable installation. Changing the blade's mounting angle can adjust the pump's head and head. According to the number of impeller in axial flow pump, axial flow pump can be divided into single and secondary two. The pump does not need to be irrigated.

Centrifugal pump

Centrifugal pump depends on the impeller in the high-speed rotation by the centrifugal force generated by the impeller to produce water out of the vacuum state, the atmospheric pressure of the river or well water pressure for the impeller, so the cycle, the water is constantly being thrown out of the centrifugal pump impeller is closed, Semi-closed and open type 3. The adjacent blades of the enclosed impeller and the inner wall of the front and rear wheel covers constitute a series of curved blades with high pumping efficiency for pumping water.

Mixed flow pump

The mixing pump is a pump between the centrifugal pump and the axial flow pump: the water entering the impeller, combined by the centrifugal force and the thrust of the impeller, is an oblique flow, also known as a diagonal pump. According to the pump shaft position, the mixed flow pump is divided into vertical and horizontal two, horizontal pump shell is usually volute type, generally used for I-lB said; vertical pump shell is usually guide leaf type, such as HL, H1 or LN instructions.

Submersible pumps

The submersible pump is a vertical motor and pump that is installed directly from the water in the pump, with a watertight seal that can work underwater, called submersible pumps. According to its use of different technical measures, divided into dry, oil-filled and wet type 3. Common submersible pumps and sewage pumps and single-phase submersible pumps. Submersible pumps are widely used in rural well water irrigation, pastures and farms for liquid feed and construction.

Deep well pump

Deep well pump is a multi-stage centrifugal pump that can pump deep groundwater to the ground. Its structure is more complex, the flow and lift a wide range, but the installation, maintenance more difficult, more expensive, quality requirements are good. Commonly used deep well pump QJ), QJT, QS, QY type.

Deep well pumps and shallow wells are suitable for agricultural production and extraction of residential groundwater for irrigation.

Shallow well pump

A shallow well pump is a centrifugal pump with a long drive shaft for pumping well water. Pump structure is simple, reliable operation, high efficiency, suitable for shallow wells.
