The Ronix RH-4021 centrifugal pump is a compact 1HP electric water pump designed for clean-water transfer, irrigation, domestic water supply, and light industrial applications. With a maximum flow rate of 6.6 m³/h and a maximum head of 32 m, it provides a practical pumping solution for distributors, contractors, and equipment brands looking for a reliable electric centrifugal pump for everyday water handling.
Powered by a 220–240V motor and equipped with thermal protection, the RH-4021 is built for stable operation and long service life. Its cast iron pump housing, brass impeller, copper winding, and ceramic/graphite mechanical seal provide a solid configuration for regular pumping work.
The RH-4021 uses a 1HP electric motor running at 2850 RPM. The motor is designed for S1 continuous-duty operation, making the pump suitable for applications that require regular and repeated water transfer.
The 220–240V voltage range also makes this model suitable for common residential, commercial, and light industrial power systems.
With a maximum flow of 6.6 m³/h, the RH-4021 can handle a variety of clean-water transfer tasks without requiring a large pump system.
It can be used for moving water between tanks, supplying water to buildings, and supporting small-scale irrigation systems.
The pump delivers a maximum head of 32 meters, providing sufficient pressure for many domestic and small commercial water supply applications.
Its minimum head is 3 m, while the working pressure reaches 3.2 bar.
The RH-4021 offers a suction height of up to 8 meters, giving users more flexibility when the water source is located below the pump.
This makes it useful for water transfer from tanks, wells, reservoirs, and other clean-water sources where a self-priming arrangement is required.
The pump housing is manufactured from cast iron, offering good mechanical strength and durability for regular use.
The motor housing is made from aluminum, helping maintain a practical balance between durability and overall equipment weight.
A brass impeller is used inside the pump. Brass provides good corrosion resistance and is well suited to clean-water pumping applications.
The single-impeller configuration keeps the pump structure relatively straightforward, making it a practical choice for distributors and service teams.
The RH-4021 uses a ceramic/graphite mechanical seal to help reduce water leakage around the shaft during operation.
The mechanical seal, combined with the brass impeller and cast iron pump body, creates a dependable configuration for regular clean-water applications.
Built-in thermal protection helps protect the motor against overheating during operation.
This feature is particularly useful for applications where the pump may be operated frequently or for extended periods.

The RH-4021 is designed for clean water and non-aggressive liquids that are free from abrasive particles, solids, and crystallized materials. Its compact design and practical performance make it suitable for a range of water pumping applications.
The RH-4021 can be used as a domestic water pump for transferring clean water between tanks, supplying water to residential systems, and supporting everyday water distribution.
For gardens, small agricultural areas, and landscaping projects, the RH-4021 can work as an irrigation pump for transferring water from a tank or other clean-water source.
The 1HP configuration provides a convenient solution for garden watering and small landscaping systems where a compact electric water pump is preferred.
The pump can be used to move clean water between storage tanks, reservoirs, and other water containers. Its 8 m suction capability adds flexibility when the water source is positioned below the pump.
The RH-4021 is also suitable for selected light industrial water transfer applications, provided that the pumped liquid meets the specified temperature and chemical compatibility requirements.
For distributors and importers, the RH-4021 offers a balanced specification that fits several common water-pumping categories.
Standard 1HP configuration: Easy to position within residential, irrigation, and general-purpose water pump ranges.
Common 220–240V power supply: Suitable for many markets using standard single-phase electrical systems.
Practical port size: The 1" × 1" inlet and outlet configuration works with commonly used plumbing connections.
Durable construction: Cast iron pump housing, brass impeller, copper winding, and stainless-steel shaft provide a robust component combination.
Multiple application scenarios: One model can cover domestic water supply, garden irrigation, water transfer, and light industrial use.
Easy product positioning: The RH-4021 can be marketed as a 1HP centrifugal water pump, electric water pump, irrigation pump, or general-purpose clean-water pump depending on the target market.
For tool distributors, importers, and private-label brands, the Ronix RH-4021 can serve as a practical addition to a professional water pump product range.
Its established 1HP configuration and standard electrical specifications make it easier to position across different sales channels. For buyers developing their own product portfolio, factors such as branding, packaging, product configuration, and market-specific requirements can be discussed according to the project.
Whether you are sourcing a wholesale centrifugal pump, developing an OEM water pump, or expanding an existing irrigation equipment range, the RH-4021 provides a straightforward platform for B2B purchasing.
