Stainless steel lobe pumps for Lub oils

Lub oil is a kind of high-viscosity medium. It is used in various types of automobiles and machinery to reduce friction and protect liquid and semi-solid lubricants of machinery and processed parts. It is mainly used for lubrication, cooling, rust prevention, cleaning, sealing and Buffer and other functions. Our pumps have a strong self-priming capacity and can transport materials with a viscosity of up to 1.5 million Cp, which is energy efficient.

Bonve rotary Lobe Pumps for lube oils


Lub oil pump factory


Lube oils are liquid or semi-solid lubricants used in various types of automobiles and machinery to reduce friction and protect machines and machined parts. Mainly used for lubrication, cooling, rust prevention, cleaning, sealing and cushioning.


The problem


Screw pump and gear pump are normal to see for lube oil transferring. But usually users will face below problems


Screw pumps

Heavy damage might be caused due to dry run

Sensitive to the change of viscosity

The fluid may leak out of the pump body and cause pollution to the environment and the pump body.

Maintenance is inconvenient

Gear pump

The inter-tooth groove of the end cap and gear constitutes a number of fixed sealing working chambers, which can only be used as a dosing pump

Unbalanced radial force, large flow artery, high noise

Low efficiency, poor interchangeability of parts, difficult to repair after wear

High cost of wearing part to replace


The solution


With the characteristics of low rotation speed and high output torque, Bonve rotary lobe pump shows his talents to transfer high viscosity lub oils.  Its unique working principle works with a strong drive system, ensure that the pump can output a strong driving torque at low speed, can guarantee continuous, non-stagnant transferring.


Advantages of Bonve Lobe Pumps


  • Gap is kept between the rotors to allow no friction, thus to ensure long service life.
  • Simple installation and disassembling easy maintenance and cleaning, strong resistance to wearing.
  • High efficiency and energy- saving, stable transmission, low failure rate, good sealing and low noise.
  • A heat retaining device can be built in structure.
  • Suitable temperature: 1~250c degree.


How Bonve Lobe pump works?


Bonve Lobe pump work


The even rotation of the rotor pair creates a vacuum on the priming side of the pump, which can be defined by the direction of rotation of the drive. This vacuum draws the liquid into the pump chamber. With further rotation, the pumped medium is conveyed past the pump wall into the pressure area. Up to six chamber charges are displaced with each drive rotation– depending on the rotor type. When the rotor is at a standstill, the pump seals off almost completely.
