What is the mounting method of a tandem gear pump?
Hey there! As a supplier of tandem gear pumps, I often get asked about the mounting methods of these pumps. So, I thought I'd write a blog post to share some insights on this topic.
First off, let's understand what a tandem gear pump is. A tandem gear pump consists of two or more gear pumps connected in series or parallel. This setup allows for increased flow rates or pressure capabilities, making them suitable for a wide range of applications, from industrial machinery to automotive systems.
Now, let's dive into the different mounting methods for tandem gear pumps.
Flange Mounting
One of the most common mounting methods for tandem gear pumps is flange mounting. In this method, the pump is attached to a flat surface using a flange. The flange has holes that align with corresponding holes on the mounting surface, and bolts are used to secure the pump in place.
Flange mounting offers several advantages. It provides a stable and secure connection, ensuring that the pump remains in place even under high-pressure conditions. It also allows for easy installation and removal of the pump for maintenance or replacement.
When choosing a flange for your tandem gear pump, make sure to select one that is compatible with the pump's specifications. Consider factors such as the size, material, and pressure rating of the flange.
Foot Mounting
Foot mounting is another popular mounting method for tandem gear pumps. In this method, the pump is supported by feet that are attached to the bottom of the pump housing. The feet are then bolted to a flat surface, such as a baseplate or a machine frame.
Foot mounting is a simple and cost-effective way to install a tandem gear pump. It provides good stability and support, especially for larger pumps. However, it may require more space compared to flange mounting.
When using foot mounting, it's important to ensure that the mounting surface is flat and level. This will help prevent any misalignment or vibration issues that could affect the performance of the pump.
Shaft Mounting
Shaft mounting is a specialized mounting method that is used when the tandem gear pump needs to be directly connected to a drive shaft. In this method, the pump is mounted on the shaft using a coupling or a spline connection.
Shaft mounting offers a compact and efficient way to install a tandem gear pump. It eliminates the need for additional mounting hardware and reduces the overall footprint of the system. However, it requires precise alignment of the pump and the drive shaft to ensure smooth operation.


When using shaft mounting, make sure to use a coupling or spline that is compatible with the pump's shaft size and torque requirements. Also, ensure that the drive shaft is properly supported and lubricated to prevent premature wear and failure.
Considerations for Mounting
Regardless of the mounting method you choose, there are several important considerations to keep in mind when installing a tandem gear pump.
- Alignment: Proper alignment is crucial for the smooth operation of the pump. Make sure that the pump is aligned with the drive shaft or the mounting surface to prevent any excessive stress or vibration.
- Vibration Isolation: Tandem gear pumps can generate vibrations during operation. To minimize the impact of these vibrations on the pump and the surrounding equipment, consider using vibration isolation mounts or pads.
- Accessibility: Ensure that the pump is easily accessible for maintenance and inspection. This will make it easier to perform routine tasks such as oil changes, filter replacements, and seal inspections.
- Environmental Conditions: Consider the environmental conditions in which the pump will be operating. If the pump will be exposed to extreme temperatures, moisture, or corrosive substances, make sure to choose a mounting method and materials that are suitable for these conditions.
