Decades of Vacuum Technology Evolution
Nantong Rongheng has refined the three-blade vacuum pump design over three decades. Our focus on precision machining ensures that internal clearances are minimized, allowing for higher ultimate vacuum levels while maintaining the mechanical integrity that the Rongheng brand is known for.
| Ultimate Vacuum | -10kPa to -80kPa |
| Suction Capacity | 0.8 - 180 m3/min |
| Seal Arrangement | Lip Seals / Piston Rings |
| Noise Level | <80 dB(A) with silencer |
Vacuum Process Applications
- Vacuum packaging and bottling
- Industrial central vacuum cleaning
- De-aeration of liquids and resins
- Pneumatic suction conveying
Vacuum Seal Metallurgy
Standard rotors are machined from high-tensile ductile iron. Vacuum-specific seals are utilized to maintain pressure integrity and prevent ambient air leakage into the process stream.
