Positive Displacement Lobe Pumps for Oil Products And Chemical Unloading
Accuvon rotary lobe pumps
Oil products and chemical unloading pumps are typical applications in petrochemical technology. Accuvon provides its rotary lobe pumps for oil products transportation. Pump meets theAPI676 and the sealing system meets the API682.
Accuvon rotary lobe pump has a strong hybrid transport capacity of gas and liquid, which can empty the products in the pipeline. In addition the pump also allows short -time drying, has stable unloading, simple process, and high efficiency. It is currently widely used by large chemical companies such as Sinopec and PetroChina.
Oil products must ensure no sparks, electrostatic.and leakage during the transportation.Accuvon pump is equipped with brass rotor and EPDM rotor through anti-static processing to ensure the safety of transporting flammable and explosive and easy to corrode products.
Operating Principles:
When pump lobes rotates, the space between 2 lobes increase, it will create a partial vacuum to transfer fluid into pump chamber, The pump shaft keeps turning, lobes will continue to create space to delivery fluid, the tolerance between lobes and chamber ensure the space is suitable to filled. When the pump chamber is fully filled, the fluid will be transfer to outlet.

Construction
1. The quick-release cover
Access to all wetted parts by simply loosening four ring nuts – maintenance without removal of pipe or drive systems.
2. The rotors
Large selection of high-quality rotors for almost pulsation-free pumping of the medium.
3. The casing protection
Depending on its size, the BLUEline pump is available with and completely without protection plates and liners. When pumping abrasive media containing solids, the protection plates and liners protect the pump casing from wear and can be replaced in a matter of minutes.
4. The intermediate chamberand shaft seal
The large-volume quench chamber is oil-filled and ensures the highest degree of safety. The ideal mechanical seal is selected depending on the medium.
5. The carrier and timing gear
The high-quality and maintenancefree carrier and timing gear guarantees a smooth and even operation of the rotors. The result is a long service life of the pump.
