Rotary Piston Pump Fluid Compatibility Guide

Introduction

What is a Rotary Piston Pump?

A rotary piston pump is a type of positive displacement pump that uses a rotary motion to compress and move fluid through the pump. It consists of a rotor with multiple pistons that rotates inside a cylinder. As the rotor turns, the pistons move in and out of their cylinders, generating suction and compression of the fluid. Rotary piston pumps are commonly used in applications requiring high vacuum levels and high pumping speeds.

Fluid Compatibility Issues

Fluid compatibility is an important consideration when selecting a rotary piston pump for an application. Incompatible fluids can cause a range of issues, from reduced pump performance to complete failure of the pump. The most common problems associated with fluid incompatibility include:

• Corrosion of pump components
• Contamination of the pumped fluid
• Reduced pumping speed
• Reduced ultimate vacuum level
• Damage to the pump

Fluid Compatibility Solutions

Choosing the Right Pump Material

The first step in ensuring fluid compatibility is to select a pump material that is compatible with the fluid being pumped. The most common materials used for rotary piston pumps are stainless steel, cast iron, and aluminum. The choice of material depends on the type of fluid being pumped and its chemical composition.

Using a Chemical Resistant Coating

Another solution for fluid compatibility is to apply a chemical resistant coating to the pump components. This coating acts as a barrier between the fluid and the pump, preventing corrosion and contamination.

Regular Maintenance

Regular maintenance of the pump is also important for ensuring fluid compatibility. This includes cleaning the pump after use, replacing worn or damaged parts, and monitoring the pump’s performance over time.

Steps to Solve Fluid Compatibility Issues

Step 1: Identify the Problem

The first step in solving fluid compatibility issues is to identify the problem. This may involve testing the fluid for chemical compatibility, inspecting the pump for signs of corrosion or damage, or monitoring the pump’s performance over time.

Step 2: Choose the Right Solution

Once the problem has been identified, the next step is to choose the right solution. This may involve selecting a different pump material, applying a chemical resistant coating, or performing regular maintenance on the pump.

Step 3: Implement the Solution

The final step is to implement the chosen solution. This may involve replacing pump components, applying a coating, or performing regular maintenance tasks.

Points to Note

• Always select a pump material that is compatible with the fluid being pumped
• Regular maintenance of the pump is important for ensuring fluid compatibility
• Chemical resistant coatings can provide an additional layer of protection against fluid incompatibility
• If fluid compatibility issues persist, contact the technical department of Ever-Power for assistance

Frequently Asked Questions

Q1: What fluids are compatible with stainless steel rotary piston pumps?

A1: Stainless steel rotary piston pumps are compatible with a wide range of fluids, including water, oils, and solvents. However, they are not suitable for pumping corrosive fluids or fluids containing abrasive particles.

Q2: Can a chemical resistant coating be applied to an existing pump?

A2: Yes, a chemical resistant coating can be applied to an existing pump. However, it is important to ensure that the coating is compatible with both the pump material and the fluid being pumped.

Q3: How often should I perform maintenance on my rotary piston pump?

A3: The frequency of maintenance depends on the type of pump and the application. In general, it is recommended to perform maintenance at least once per year, or more frequently for pumps operating in harsh environments.

Q4: What is the maximum vacuum level that can be achieved with a rotary piston pump?

A4: The maximum vacuum level depends on the pump design and the type of fluid being pumped. In general, rotary piston pumps can achieve vacuum levels of 10-3 to 10-6 torr.
