RH00300N Single-Stage Directly-Coupled Rotary Vane Vacuum Pump
Overview and features of the product
The single-stage direct-drive rotary vane pump is powered by electricity. The pump features direct-drive rotor operation with speeds reaching up to 3,000 RPM, offering advantages such as a compact design, small footprint, lightweight construction, high pumping speed, and minimal vibration and noise. Not only is this pump highly efficient and energy-saving, but it’s also easy to install and maintain—making it both safe and reliable.
• Long-lasting blades, low noise levels, easy maintenance, capable of withstanding higher water vapor, and requiring infrequent upkeep.
• Low noise, low vibration, air-cooled, convenient and easy to use.
• It continues to function effectively in high-temperature environments and maintains excellent pumping speed even under low vacuum pressure.
• Built-in filter element and filter for superior filtration performance, along with a built-in one-way valve to prevent vacuum oil from flowing backward.
• The standard features an air-cooling design, but a water-cooling unit can be added as an option, making it suitable for use in environments with higher ambient temperatures.
• Built-in air purge valve handles air with heavier moisture content, and features a high-efficiency oil-mist separator—plus, the installation process is remarkably simple.
• We offer a wide range of vacuum systems designed for various applications requiring central negative pressure. Reliable and durable, these systems are ideal for both rough and medium-vacuum applications.
• It can be used independently, as a backing pump for other high-vacuum or ultra-high-vacuum pumps, or as a roughing pump for ultra-high-vacuum systems.

Precision Machining
The forged billet is turned by a CNC lathe to remove most of the allowance, making the shape of the rotor closer to the design size, while leaving an appropriate machining allowance for the subsequent fine processing. The precision machining of the screw profile is carried out using a MAZAK precision machining center. Through precise programming and processing, the profile accuracy of the screw rotor is controlled within the design requirements.
Assembly
After the installation engineer checked the vacuum pump materials, they assembled the vacuum pump products in accordance with the drawing requirements and conducted pressure tests and usage debugging on the assembled vacuum pump products.
Quality inspection
After each processing step of the product is completed, the quality inspection team conducts quality checks based on the processing technology and product standards. Products that do not meet the standards need to be reworked or scrapped.
Shipment
After all processing procedures are successfully completed, the staff responsible for packaging and shipping will check each product against the shipping documents one by one. Once the information is accurate, they will contact the logistics to arrange for shipping.
