Product Advantage – Fully Enclosed Internal Gear Pump
System applicationFully enclosed structural design
The independently innovated fully enclosed electro-hydraulic integrated drive pump patent technology completely eliminates leakage risks. The pump body structure is more compact, high-pressure resistant, with low vibration and noise, good heat dissipation performance, and high operating efficiency.
Patent profile technology
Through the optimization design of rotor profiles, programming algorithms and other core technologies, the lubricating area and load-bearing capacity of the rotor are improved, dead volume and cavitation are eliminated, and the designed pump has excellent performance such as high efficiency and low cavitation margin.
High-efficiency variable frequency motor
By designing a new type of fully immersed device, using the pumped liquid to briefly circulate around the motor to take away heat, and then entering the pump outlet for pressure increase, the motor temperature rise can be effectively reduced, thereby improving the service life of the machine.
Low-noise operation control
Through flow path and profile optimization, the balance state of internal components is obtained, the fluid noise generated by the high and low pressure interaction in the pump cavity is reduced, and at the same time, noise reduction composite materials are selected, and the internal structure is reasonably arranged to effectively reduce the operating noise.
Friction pair optimization design
By optimizing the friction pair design and selecting the friction pair matching parts materials, the compressive strength of the lubricating film is improved, thereby improving the wear resistance, reducing the friction coefficient, improving the mechanical efficiency, and maximizing the effective power.
Modular integrated manufacturing
Based on the building block principle, the position accuracy of internal core components is ensured, and the standardization of segment manufacturing is realized. Through the rapid detection of key product indicators, the product energy efficiency indicators are improved while ensuring a large-scale yield rate.
High-precision processing breakthrough
Through the control of high-precision equipment, the machining allowance after assembly is reduced, and a high-precision consistent forming process technology is realized, ensuring the coupling accuracy of the core rotor, effectively improving the reliability and service life of the pump.
Fully automatic intelligent assembly
The fully automated assembly intelligent production line meets the requirements of the product for assembly accuracy and process, effectively improves production capacity and manufacturing stability, and greatly improves production capacity.
Product Advantage – Fully Enclosed Centrifugal Refrigerant Pump
Continuous pulsation-free conveying
The centrifugal refrigerant pump achieves smooth, continuous flow with no pulsating disturbances, ensuring stable operation of the refrigeration system and preventing temperature fluctuations caused by flow variations.
Structural optimization design
The impeller is arranged symmetrically, effectively balancing axial forces and significantly extending the pump’s service life. The pump body features a simple structure with no complex transmission components, resulting in zero wear and a low failure rate.
Runs smoothly and quietly
Fully enclosed and completely silent design, featuring low vibration and minimal noise (≤57 dBA), which causes little disturbance to the overall system operation and ensures a quiet and reliable cooling environment.
High refrigerant compatibility
It is compatible with a variety of mainstream non-conductive refrigerants, including R134a, R410A, R22, R407C, R410A, R1234ze, and R515b, meeting the needs of different systems.
Wide operational adaptability
Wide temperature range (-40°C to +80°C), wide pressure rating (up to 45 bar), suitable for altitudes up to 5,000 meters, and equipped with dustproof, waterproof, and sand-resistant features, making it adaptable to a variety of challenging operating environments.
Feature customization
It can accommodate low-level installation of the storage tank (H ≤ 100 mm) and enables full-capacity two-phase gas-liquid flow transportation (gas content s ≥ 20%), significantly enhancing system adaptability.
Wide flow pressure range
The multi-stage pump features a symmetrically arranged structure and allows for wide-range frequency adjustment (100–350 Hz), enabling flow rates from 0.6 times the rated flow rate (Qrated) to 1.5 times the rated flow rate (Qrated). The pressure can range from 2 bar to 8 bar.
Inducer Optimization Design
An inducer wheel can be installed upstream of the primary impeller, allowing the storage tank to be mounted at an installation height close to zero. This significantly reduces the required installation space and lowers the consumption of copper tubing, thereby reducing the overall system cost through optimized inducer wheel design.
Two-phase gas-liquid flow transport
A variety of impeller configurations are available to enable the transportation of gas-liquid two-phase flow (gas phase content ≤20%).
