Roots Type Vacuum Pump
The MB-type integrated impeller-shaft Roots blower is an internationally advanced model with independent intellectual property rights, featuring a one-piece cast impeller-shaft structure for high overall strength, good rigidity and reliable operation. It adopts anti-adhesion-wear technology and piston ring sealing for excellent sealing, minimal leakage and high efficiency, plus an aluminum alloy cast air-cooled oil tank with an efficient oil tray to avoid water cooling even under high pressure. It supports vertical and horizontal installation, directly replacing foreign similar models. Paired with the Roots Vacuum Pump (flow: 2.3-90.5m³/min, vacuum degree: -9.8 to -49kPa), it’s used in sewage treatment, petrochemicals, etc., to convey clean air.
The MB Series integrated impeller-shaft blower is an internationally competitive Roots blower developed by our company. It incorporates proprietary intellectual property rights, built upon the introduction of advanced American blower technology, assimilated through digestion and absorption, and integrated with our company's core and key technologies in blower design and manufacturing accumulated over 40 years, followed by further innovation.
