INTERNAL ECCENTRIC GEAR PUMP
Internal eccentric gear pumps are positive displacement pumps and can be used for many purposes. These pumps have two basic movable parts, perimeter gear and idler gear. Therefore, they are easy to maintain, durable and safe. It is designed specifically for every conditions and processes by our expert engineers.
Working Principle
1- While the peripheral gear (rotor) rotates in the direction of the arrow with the circular motion it receives from the motor; the inner idler gear (star) rotates and separates from the ring gear. The fluid fills the gap created by the separation of the gears.
2- The half moon (crescent) in the pump cover and the gears are separated from each other. Thanks to by gear gaps are transported the fluid.
3- While the ring gear and idler gear are intertwined, the fluid is thrown into the discharge channel.
4- The fluid thrown into the discharge channel moves through the installation and the fluid is transferred.
ADVANTAGES
- They occupy less space than external gear pumps that provide the same flow and flow conditions.
- It is easy to maintain and durable.
- Suitable for high viscosity liquids.
- It provides a regular discharge flow.
- It has a high suction capacity.
USAGE AREAS
- Fuel Oil Service Tanks, Gas Oil, Diesel Tankers
- Resin and Polymers
- Asphalt and Bitumen
- Paper and Paint Industry
- Small scaled hot oil circulation
- Pharmaceutical, chemical and detergent industry
- Food Industry

HELICAL GEAR PUMPS
Maxwor Helical Gear pumps are positive displacement pumps and they are pumps working with the gear pump principle. They are used for the transfer of fluids with low and medium viscosity that can operate at higher speeds than internal gear pumps.
Working Principle
1- Pump shaft transmits the circular movement with gear on shaft to other gear on opposite direction. Then, the fluid fills the gap created by the separation of these gears.
2- The fluid filled into the gap is transported towards the discharge channel of the pump between the gears gaps.
3- As the gears are intertwined, the fluid is transferred out of the discharge channel.
4- The fluid transferred to the discharge channel moves through the installation and the transfer process takes place.
ADVANTAGES
- They can work at high speeds.
- Suitable for low and medium viscosity fluids.
- Due to the fact that they have helical gear, they work quietly.
- It is easy to maintain and long lasting.
- They provide uninterrupted flow.
USAGE AREAS
- In industrial applications
- Molasses
- Oil & Gas
- Fuel
- In high volume transfers
