A ROTARY POSITIVE DISPLACEMENT PUMP - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240052834 titled 'A ROTARY POSITIVE DISPLACEMENT PUMP
Simplified Explanation
The patent application describes a rotary positive displacement pump with a unique design to provide a positive pumping effect on fluid products.
- The pump includes two parallel drive shafts with constantly meshing gears, rotating in opposite directions.
- A rotor casing connected to the housing houses two rotors connected to the drive shafts, rotating in opposite directions to pump fluid.
- Sealing arrangements prevent leakage of fluid from the cavity towards the rear side of the casing.
- A heating device is detachably fastened to the rear casing wall to heat the casing, sealing arrangements, and fluid product within.
- Potential Applications
- Industrial pumping systems
- Chemical processing plants
- Oil and gas industry
- Problems Solved
- Leakage of fluid in pumping systems
- Inefficient pumping mechanisms
- Lack of heating options for maintaining fluid viscosity
- Benefits
- Efficient and reliable pumping of fluid products
- Reduced risk of leakage and contamination
- Heating capability for maintaining optimal fluid properties
Original Abstract Submitted
a rotary positive displacement pump comprises a housing rotationally supporting first and second parallel and axially extending drive shafts having constantly meshing gears such that the drive shafts rotate in opposite directions. a rotor casing is connected to a front side of the housing and has axial rear and front walls and a circumferential side wall jointly defining a pumping cavity. the casing houses first and second rotors drivingly connected to the first and second drive shafts respectively. the rotors rotate in opposite directions and mutually interact to provide a positive pumping effect on fluid product entering the cavity. first and second sealing arrangements prevent leakage of fluid product from the cavity towards the rear side of the casing along the first/second drive shafts. a heating device is detachably fastened to the rear casing wall to heat the casing, the first/second sealing arrangements and/or any fluid product within the casing.
