The CFG explosion-proof rubber rotor self-priming rotary lobe pump is a heavy-duty positive displacement pump designed for hazardous chemical and petroleum working environments. Equipped with an explosion-proof motor, this industrial lobe pump delivers reliable tank bottom residual liquid suction. It can safely transfer flammable media including oil, diesel and alcohol, featuring strong self-priming performance, stable gas-liquid mixed conveying and long service life.
This self priming rotary lobe pump can achieve up to 8m suction head without pre-filling liquid before startup. It handles gas-liquid mixed medium smoothly and efficiently draws residual liquid from the bottom of storage tanks. It solves the common problem of residual liquid left in tanks that cannot be fully drained.
This rubber rotor lobe pump is fitted with an explosion-proof motor, meeting safety standards for explosive and flammable working sites. It minimizes safety risks when transporting oil, diesel and alcohol. The high-performance mechanical seal effectively prevents liquid leakage during continuous long-time operation.
The pump uses NBR or EPDM elastic rubber rotors. Flexible rotors prevent pump jamming when conveying liquid with tiny fine particles. The pump body can be cast iron or stainless steel. It adopts carbon, ceramic and PTFE mechanical seals for leak resistance. Flow rate ranges from 5 to 180m³/h, working pressure 0.1~1.2MPa. Flange connection ensures easy installation.
This explosion-proof lobe pump is widely used in petroleum, chemical industry, environmental protection and waste liquid recovery projects. It is suitable for conveying water, various oils, diesel and alcohol. It is an ideal piece of equipment for tank emptying, residual liquid recovery and flammable liquid transfer.
