2RH175C Two-Stage Directly-Coupled Rotary Vane Vacuum Pump
Overview and features of the product
The working pressure range is broad, making it suitable for general gases—but it cannot be used to evacuate flammable, explosive, or corrosive gases.
If the extracted gas contains significant amounts of dust, impurities, and liquids, pretreatment is required.
If extracting oxygen-rich gases or chemically reactive gases, special vacuum pump oil must be used.
• Long-lasting blades, low noise levels, easy maintenance, capable of withstanding higher water vapor, and requiring infrequent upkeep.
• Low noise, low vibration, air-cooled, and easy to use.
• It continues to operate effectively even in high-temperature environments and maintains excellent pumping speed 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 for use in environments with higher ambient temperatures.
• Built-in gas ballast valve allows handling air with heavier moisture content, and a high-efficiency oil-mist separator is included—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.
