CFG Rubber Rotor Self-Priming Rotary Lobe Pump for Oil, Diesel & Alcohol Transfer

The CFG rubber rotor rotary lobe pump is a modular positive displacement pump with strong self-priming performance. This industrial lobe pump is built for tank bottom residual liquid suction. It is equipped with a standard three-phase motor, available in cast iron or stainless steel pump body. It can transfer oil, diesel, alcohol and water stably, with flexible customization for diverse industrial fluid conveying needs.

1. Powerful Self-Priming for Tank Bottom Suction

This self priming lobe pump can reach up to 8m suction head and does not require pre-filling liquid before startup. It supports gas-liquid mixed delivery, efficiently pumping residual liquid from tank bottoms and solving incomplete liquid draining issues for storage tanks.

2. Wear-resistant NBR / EPDM Rubber Rotor

The pump adopts elastic NBR or EPDM rubber rotors. The flexible rotor design prevents pump jamming when handling media with tiny particles. It delivers smooth liquid transfer, reduces abrasion and extends the pump service life.

3. Reliable Structure & Optional Configurations

The pump body is optional with cast iron or stainless steel. It uses carbon, ceramic and PTFE mechanical seals to avoid leakage. The flow rate ranges from 5 to 180m³/h, working pressure 0.1~1.2MPa. Flange connection and flexible coupling ensure stable assembly.

4. Wide Range of Industrial Applications

This rubber rotor lobe pump is widely applied in petroleum, chemical, environmental protection and light industries. It is suitable for conveying water, oils, diesel and alcohol, perfect for tank emptying and liquid recovery projects.
