Wastewater treatment
Roots Vacuum Pump VP Series
Category:
Our company’s RH three-lobe Roots blowers, built upon the foundation of our previously successful models, have been independently developed using advanced design technologies and feature a CONCH rotor profile. This ensures smooth meshing during operation (with rotor meshing unevenness less than 0.01 mm), thereby achieving a balanced performance in terms of noise levels, flow rate, and volumetric efficiency for Roots blowers.

Product Features
Our company’s RH three-lobe Roots blowers, built upon the foundation of our previously successful models, have been independently developed using advanced design technologies and feature a CONCH rotor profile. This ensures smooth rotor meshing during operation (with a rotor meshing unevenness of less than 0.01 mm), thereby achieving a balanced performance in terms of noise level, flow rate, and volumetric efficiency for Roots blowers. 
Performance advantages:
[Low Noise] The rotor is manufactured using CNC machining technology, ensuring high precision, smooth operation, and low noise.
[Micro-vibration] Rotor dynamic balancing grade G2.5, high-speed and stable operation with minimal vibration.
【Stability】The spindle features a stepless design for high strength.
[High-pressure resistance] Optimized structural design enables the entire device to withstand pressures up to 1 MPa.
[Leak-Free] A combination of multiple sealing technologies ensures zero leakage, making it safe and environmentally friendly.
[Adaptable Operating Conditions] Integrated design featuring air-cooling, water-cooling, and open-wall panel configurations to handle complex and varying operating conditions.
[Energy Saving and Environmental Protection] Smooth operation, high compression efficiency, and low fan energy consumption.
Model Description
For the wind turbines applicable to the selected plan, please contact us as thoroughly as possible regarding the following matters:
1. Application: Distinguish between blowers and vacuum pumps. 2. Gas Properties: Provide the gas name, state (gas, liquid, or solid), temperature, and whether the gas is corrosive or explosive. In the case of mixed gases, specify the composition ratio and molecular weight. 3. Pressure: Use units such as kgf/cm², mmH₂O, mmHg, Pa, etc. Clearly differentiate between gauge pressure and absolute pressure; also indicate whether backpressure exists. 4. Airflow Rate: Unit: m³/min.
Standard state (N: 0℃, one standard atmosphere, air volume under dry gas conditions); Standard state (S: 20℃, one standard atmosphere, relative humidity of 65%—air volume under these conditions).
Inhalation status (indicated values of inhalation temperature, pressure, and humidity)
The above three air volumes can be converted to each other.
If converting Q1 to Q2:
Q2 = Q1 × P1/P2 × T2/T1
Q1: Airflow (m³/min) at absolute pressure P1 (mmH₂O) and absolute temperature T1 (K); Q2: Airflow (m³/min) at absolute pressure P2 (mmH₂O) and absolute temperature T2 (K). Site settings: Differences between indoor and outdoor environments; ambient temperature; presence or absence of hazardous areas. 5.
6. Motor: Model, output power, number of poles, other requirements
7. Drive method: Coupling, V-belt
8. Other: Operating time, whether accessories and spare parts are required, paint color
9. The allowable range for the specified air volume under pressure is ±5%.
