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.
