Specific motor power, rotational speed, impeller diameter and installation dimensions depend on the selected pump model and actual operating conditions.
The HW pump provides flow capacities from 70 to 8600 m³/h.
Its large flow range makes it suitable for medium-sized irrigation systems as well as large municipal, industrial and construction drainage projects.
With a head range of 5 to 21 meters, the pump is suitable for transferring large volumes of water over low or moderate elevation differences.
It is particularly effective in applications where high flow is more important than high discharge pressure.
The horizontal structure provides stable installation on a conventional foundation.
It also allows convenient access to the pump casing, shaft, bearings, coupling and motor during inspection or maintenance.
The pump uses a single impeller to transfer energy to the water.
The single-stage structure reduces mechanical complexity and provides a practical solution for continuous large-volume water transportation.
Water enters the impeller from one side through the suction inlet.
This simple hydraulic arrangement supports convenient installation and maintenance while meeting the operating requirements of large-flow, low-head systems.
The volute casing collects water discharged from the impeller and gradually converts velocity into pressure.
This structure helps provide stable water delivery and efficient operation within the recommended performance range.
The pump has a straightforward mechanical and hydraulic structure with fewer complicated components.
This reduces installation difficulty and simplifies routine inspection, servicing and replacement of wear parts.
The horizontal arrangement makes the pump easy to connect to the inlet and discharge pipelines.
Once the pump, motor, coupling and pipelines are correctly aligned, the unit can provide reliable operation with relatively simple operating procedures.
The pump structure allows convenient access to internal components during maintenance.
The pump casing, impeller, shaft, bearings and sealing components can be inspected and serviced according to the maintenance schedule.
The HW Horizontal Mixed-Flow Pump is widely used for transferring irrigation water from rivers, canals, lakes, reservoirs and pumping stations to farmland.
Its high flow capacity makes it suitable for:
The pump model should be selected according to the required irrigation flow, lifting height, pipeline length and water-source conditions.
The pump can be used for large-volume drainage and process-water transfer in factories, mines and other industrial facilities.
Typical applications include:
The pumped liquid should generally be free from large solids, long fibers and highly abrasive particles.
The HW series is suitable for municipal pumping stations, urban drainage systems and water-transfer projects.
It can be used for:
Its high-flow, low-head characteristics are well suited to moving large quantities of water within a relatively short period.
The pump can remove accumulated water from construction sites, foundation pits, excavation areas and temporary drainage channels.
It is suitable for projects where continuous drainage is required to maintain safe and workable site conditions.
Typical applications include:
The HW pump can also be used in water-diversion, canal-transfer and regional water-management projects.
Its broad flow range allows it to serve both individual pumping units and multi-pump station configurations.
The HW Horizontal Mixed-Flow Pump is mainly designed for transporting:
The pumped liquid should generally not contain:
Where weeds, branches, plastic or other floating debris may be present, an inlet screen should be installed to protect the pump.
A mixed-flow pump combines the operating principles of centrifugal and axial-flow pumps.
When the impeller rotates, water enters through the suction inlet and is accelerated in both axial and radial directions. This mixed flow pattern allows the pump to generate moderate pressure while maintaining a large flow capacity.
Compared with an axial-flow pump, the HW mixed-flow pump can normally provide a higher head.
Compared with a conventional radial-flow centrifugal pump, it can deliver a larger flow rate at a relatively lower head.
This makes the HW pump suitable for applications requiring:
The horizontal configuration provides several practical benefits:
Adequate maintenance space should be reserved around the pump and motor during pump-station design.
The single-stage, single-suction structure provides a simple and reliable pumping arrangement.
Its main benefits include:
The pump should be operated within its recommended performance range to maintain efficiency and reduce vibration or excessive wear.
The pump should be installed horizontally on a firm and level foundation.
The foundation should be capable of supporting the combined weight of the pump, motor, coupling and pipelines.
The pump shaft and motor shaft must be correctly aligned before operation. Misalignment may cause excessive vibration, bearing wear and coupling damage.
The suction pipeline should be as short and direct as possible. Unnecessary bends and restrictions should be avoided to reduce suction losses.
The suction pipe should remain airtight to prevent air from entering the pump.
The inlet and discharge pipelines must be independently supported so that their weight and stress are not transferred to the pump casing.
Valves and pressure-monitoring instruments should be installed where required for startup, adjustment and maintenance.
Before startup, the pump casing and suction pipeline should be completely filled with water. Dry running must be avoided.
For large-flow mixed-flow pump installations, the intake structure has an important influence on pump performance.
The pump-station design should provide:
For large projects, the hydraulic conditions of the intake channel and sump should be evaluated during system design.
Regular inspection helps maintain stable performance and extend pump service life.
Recommended checks include:
The bearings should be lubricated according to the equipment instructions and operating schedule.
When the pump is shut down for a long period, water should be drained where freezing or internal corrosion may occur.
The HW Horizontal Mixed-Flow Pump combines high flow capacity, moderate head performance and a simple horizontal structure.
Its flow range of 70 to 8600 m³/h and head range of 5 to 21 meters make it suitable for agricultural irrigation, municipal drainage, industrial water transfer and construction dewatering.
The horizontal, single-stage, single-suction volute design is easy to install and operate. It also provides convenient access for dismantling, inspection and maintenance.
For projects requiring reliable large-volume water transportation without extremely high pressure, the HW series provides a practical and economical pumping solution.
