The CFG rubber rotor rotary lobe pump is a modular positive displacement pump with reliable self-priming performance. Designed for tank bottom residual liquid suction, this industrial lobe pump can convey oil, diesel, alcohol and water. It adopts a standard three-phase motor, with optional cast iron or stainless steel pump body, flexible customization and stable running performance for industrial fluid transfer.
This self priming lobe pump can reach up to 8m suction head without pre-filling liquid. It supports gas-liquid mixed conveying and effectively sucks residual liquid from the tank bottom, solving incomplete liquid drainage problems of storage tanks.
Equipped with elastic NBR or EPDM rubber rotors, the pump avoids jamming when handling media with tiny particles. It provides smooth liquid transfer, reduces wear and extends service life compared with metal rotor lobe pumps.
The pump body is available in cast iron or stainless steel. It is fitted with carbon, ceramic and PTFE mechanical seals to prevent leakage. Flow rate ranges from 5 to 180m³/h, working pressure 0.1~1.2MPa. Flange connection and flexible coupling ensure stable assembly.
This rubber rotor lobe pump is widely used in petroleum, chemical, environmental protection and light industries. It is suitable for transferring water, various oils, diesel and alcohol, ideal for tank emptying and liquid recovery projects.
