The Helical External Gear Pump is designed for medium and high-pressure transfer applications, with versatile uses in industrial settings. This pump features a horizontal shaft that transmits circular movement to the opposite gear. As the gears separate, liquid is drawn in to fill the space between them. When the gears move closer together, this liquid is moved with a rotary motion towards the pump outlet. With a capacity for pressures up to 20 Bar (depending on the liquid viscosity), this pump excels in situations requiring uninterrupted flow for less viscous and medium-pressure applications.

How does a Helical External Gear Pump work?
The pump features a horizontal shaft, 180° port position and has 2 external helical gears.
The pump shaft operates, moving the gears which draws liquid into the port. The liquid fills the space between the gears and moves towards the outlet of the pump as the shafts turn.
The Helical External Gear Pump is ideal predominantly for industrial applications such as:
It is also suitable for transferring molasses.
