Working Principle
Helical & Spur gear pumps are positive displacement and consist of two moving parts. The pump shaft transmits the circular motion it receives from the motor to the gear (Returning Gear) on the shaft. The gears are separated from each other and a vacuum is created while the rotating gear transmits its movement in the opposite direction to the driven gear. Thanks to the vacuum created, the pump absorbs a certain amount of liquid.The liquid drawn into the pump moves towards the discharge port in the gear cavities.At the discharge port, the gears are intertwined, creating pressure and allowing the liquid to be ejected. Pump; In each revolution of the pump shaft, it transfers the liquid as much as its volume. Therefore, the capacity of the pump is directly proportional to its size and revolution. The working principle of Helical & Spur gear pumps is shown schematically below.
Helical & spur gear pumps that we manufacture; helical & spur gear pump, external ball helical gear pump, external ball & driven spur gear pump are collected in three main groups. 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 in the liquid during transfer. Spur gear pumps work in places where medium pressure is required, external ball and external ball & driven helical gear pumps work with high efficiency in the transfer of abrasive liquids, non-lubricating liquids and high temperature liquids.
