HW Type Mixed-flow Pump Impeller

The HW type mixed-flow pump impeller refers to the core flow passage component assembly of the HW series horizontal volute mixed-flow pump. It includes components such as the pump body, pump cover, impeller, pump shaft, bearing housing, and shaft seal, but does not include the motor, diesel engine, base, coupling, and other power and installation accessories. The pump head component directly determines the flow rate, head, efficiency and reliability of the pump, and is the core of the overall pump performance.

Large flow rate at the outlet, less prone to clogging, simple operation and smooth running. Strengthen the pump body. The pump body is reinforced and thickened, which is resistant to wear, has excellent sealing performance, and is sturdy and durable.
Thickened bracket
Increased and thickened bracket, sturdy and stable, thickly cast, solid and firm, runs smoothly
Stable and powerful performance, runs smoothly, high efficiency, widely applicable, easy to use 

Integrated core components, ready to use immediately: The HW type mixed-flow pump head integrates the flow passage components, rotor, bearings, and seals. Users only need to connect the power machine and the pipeline to start operation. There is no need for self-assembly or alignment, saving installation time on-site.
Front and rear opening boom structure, no need to dismantle the pipeline for maintenance: By opening the pump cover, the rotor assembly can be withdrawn. The inlet and outlet pipelines remain unchanged. When purchasing a pump head for replacement of an old pump, it can be installed in place without changing the pipeline layout.
Wide efficiency range, suitable for various power sources: The hydraulic model of the pump head is mature, and the efficient range covers 40% to 100% of the flow rate range. Regardless of whether the motor is directly connected or driven by a diesel engine belt drive, it can maintain a high efficiency.
High interchangeability, universal spare parts: The HW series is a nationally jointly designed product. The main components (impeller, shaft sleeve, seal) of the pump head are interchangeable with various brands. Users can easily maintain and purchase spare parts.
Material selection, suitable for different media: The standard model is used for transporting clear water. A stainless steel impeller can be selected for mild corrosive media, or a high-chrome cast iron can be used for water containing sand. The pump head body can be retained, and only the flow passage components need to be replaced to switch the working conditions.

The HW type mixed-flow pump head is widely used in pump station renovation and replacement (replace the old pump head directly after it wears out, keeping the original motor and base intact), OEM matching (agricultural machinery factories, pump assembly plants purchase pump heads to assemble complete machines), emergency spare parts reserve (防汛 departments, irrigation management offices have inventory of spare parts, ready to replace faulty pump heads at any time), and self-assembly of mobile pump trucks (purchase pump heads in combination with diesel engines and trailer chassis).
