What is a Helical Gear Pump?

Helical gear pumps are positive displacement pumps. It consists of two moving parts. Suitable for medium and high viscosity liquids. For a more reliable and controlled fluid flow, the speed must be adjusted appropriately for high viscosity fluids.

Working Principle of Helical Gear Pumps

The helical gear pump transmits the circular motion that the pump shaft receives from the motor to the rotating 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.

With this vacuum, the pump absorbs some liquid and the liquid is pushed towards the discharge port. In the discharge mouth, the gears are intertwined and pressure is created. Thus, it allows the liquid to be thrown out. The pump transfers liquid as much as its volume.

Helical Gear Pump Usage Areas

Helical gear pumps, often referred to as helical pumps, are widely used in various industries due to their efficiency and smooth operation. These pumps are primarily employed in applications where the transport of fluids with varying viscosities is required. One of the key uses is in the automotive industry, where they are used to circulate oil within engines and transmissions, ensuring proper lubrication. They are also utilized in hydraulic systems to provide consistent pressure for machinery operations, including heavy construction equipment, agricultural machinery, and industrial machinery.

In the food and beverage industry, helical gear pumps are employed for pumping thick liquids such as syrups, oils, and creams. Their ability to handle viscous materials without compromising the flow rate makes them ideal for these applications. Additionally, these pumps are used in chemical processing, where precise and reliable fluid transfer is crucial for maintaining the quality and safety of the product. In such settings, they often handle abrasive or corrosive liquids, and their design ensures minimal wear and tear.

Helical gear pumps are also widely used in the oil and gas industry, particularly in the transportation of fuels, lubricants, and other essential liquids. The pump's design minimizes pulsation, providing a steady and continuous flow of fluids, which is especially important in sectors where consistent performance is critical. Furthermore, their versatility extends to the pharmaceutical industry, where they are used in the accurate dosing of liquids in the manufacturing of medicines and chemicals.

These pumps are favored in such settings due to their quiet operation, high efficiency, and long service life, making them indispensable in industries that require reliable and efficient fluid handling solutions.
