Gear pump

A gear pump is a type of positive displacement pump that uses the meshing of gears to pump fluid by displacement. It is one of the most common types of pumps for hydraulic fluid power applications and is also used in chemical installations to pump high viscosity fluids.

Basic Function

The basic function of a gear pump is to transfer fluid from one place to another. It operates by using two or more gears that mesh together. As the gears rotate, they create a vacuum at the pump inlet, drawing fluid into the pump. The fluid is then trapped between the teeth of the gears and the pump casing, and is carried around the casing to the discharge side of the pump, where it is forced out.

Operation

Gear pumps are typically used in applications where a constant flow rate is required. They are capable of handling a wide range of viscosities and can operate at high pressures. The flow rate of a gear pump is directly proportional to its speed, making it easy to control and adjust.

Maintenance

Regular maintenance of gear pumps is essential to ensure their efficient operation and longevity. Key maintenance tasks include:

• Regularly checking and replacing worn gears and bearings.
• Ensuring that the pump is properly lubricated to reduce friction and wear.
• Inspecting seals and gaskets for leaks and replacing them as necessary.
• Monitoring the pump for unusual noises or vibrations, which may indicate a problem.

Failure

Common causes of gear pump failure include:

• Wear and tear of gears and bearings due to inadequate lubrication or excessive pressure.
• Contamination of the fluid being pumped, which can cause damage to the gears and other components.
• Overheating, which can result from operating the pump at too high a speed or pressure.
• Cavitation, which occurs when the pump is not properly primed or when there is a restriction in the inlet line.

To prevent failure, it is important to follow the manufacturer’s guidelines for operation and maintenance, and to address any issues promptly.
