Advantages of Gear Pump
- Transfer medium sized solids.
- No friction between surfaces during liquid transfer.
- The pump can be cleaned while connected to the service line.
- Silent operation.
- In pumps with heating jacket option, the fluid smoothly passes through, which prevents freezing, with easy flow. It transfers the product smoothly without damaging its properties.
- Optionally, a panel can be applied on a portable wheeled chassis, providing convenience in different areas of applications. The only required action is to connect the electrical line to chassis’ panel.
- Conveniency, especially during food tankers’ unloading and loading operations, by taking the energy from the concerned vehicles.
- It transfers low and high viscosity products without any problems.
Information on Gear Pump Selection
In selecting gear pumps, the medium qualification, the transferring line specifications, and the enquired technical details to be taken into consideration. These enquired parameters are shown in detail in following table.
Internal Eccentric - GEAR PUMPS
Internal eccentric gear pumps are positive displacement and consist of two moving parts. As the ring gear connected to the pump rotating shaft, it transmits rotating power to the idler gear, and the idler gear starts rotating. During this rotation, the idler gear and the ring gear are separated from each other by the crescent and the vacuum created. The created vacuum, sucks a certain amount of liquid. The sucked liquid inside the pump moves towards the discharge port in gear cavities. At the discharge port, the idler and the ring gear interlock, creating pressure and allowing the liquid to be expelled. In each pump shaft rotation, it transfers liquid as much as the pump capacity. Therefore, the capacity of the pump is directly proportional to its size and speed. The working principle of internal eccentric gear pumps is shown schematically as below.
Internal eccentric gear pumps falls into two main categories: with and without console.
The console provides the opportunity to transform the inlet and outlet ports of the pumps into eight different positions (45º apart) for ease of installation, and since the pump shaft bearing is more rigid, it allows the pumps to operate for a long time under more severe conditions.
Helical and Straight - GEAR PUMPS
Helical & Spur gear pumps are positive displacement and consist of two moving parts. The pump shaft transmits the circular motion received from the motor to the shaft gear. As the driving gear transmits its movement in the opposite direction to the driven gear, the gears separated from each other and a vacuum created. The creaed vacuum sucks in a certain amount of liquid. The sucked liquid pushed into the pump discharge port in gear cavities. At the discharge port, the gears interlock, creating pressure and allowing the liquid to be expelled. In each shaft rotation, the pump transfers liquid as much as its capacity. Therefore, the capacity of the pump is directly proportional to its size and speed. The working principle of Helical & Spur gear pumps is shown schematically below.
Our manufacturing Helical & Spur gear pumps fall into three different groups: helical & spur gear pump, external ball helical gear pump & external ball & driven spur gear pump.
Helical gear pumps operate with high efficiency, where silent operation and uninterrupted flow are required. They have the ability to pass small and crushable particles during liquid transfer. Spur gear pumps operates with high efficiency, where medium pressure is required, and external ball & driven helical gear pumps operate with high efficiency for abrasive, non-lubricating and high temperature liquids.
