The CFG Rubber Rotor Rotary Lobe Pump is a modular positive displacement pump with strong self-priming ability. Equipped with an optional explosion-proof motor, this industrial lobe pump is specially designed for tank bottom residual liquid suction. It can transfer oil, diesel, alcohol and water stably, featuring robust construction, low noise and flexible customization for various industrial liquid transfer tasks.
This self priming lobe pump achieves up to 8m suction head, no need for pre-filling liquid before startup. It supports gas-liquid mixed conveying, efficiently drawing residual media from tank bottoms and solving incomplete liquid draining problems in storage tanks. Continuous and stable suction performance guarantees long-time operation.
The rotary lobe pump adopts elastic NBR or EPDM rubber rotors. The flexible rotor design prevents pump jamming when handling media with tiny particles. It delivers smooth transfer, reduces abrasion and extends pump service life compared with metal rotor lobe pumps.
The pump body is available in cast iron or stainless steel. It uses carbon, ceramic and PTFE mechanical seals to prevent leakage. Multiple motor choices are supported: standard three-phase motor, explosion-proof motor and inverter motor. Flow rate ranges from 5 to 180m³/h, working pressure 0.1~1.2MPa. Flange connection and flexible coupling ensure reliable assembly.
This rubber rotor lobe pump is widely used in petroleum, chemical, environmental protection and light industries. It handles water, diesel, alcohol and different kinds of oils. It is ideal for tank emptying, liquid transfer and medium recovery projects.
