Chemical Resitant Pumps The AVF-X series is one of the first plastic magnetic drive pumps to meet the highest European pump efficiency standards on the market (Commission Regulation (EU) No. 547/2012 with an MEI ≥0.7). This means you can rest assured knowing you are using one of the most energy efficient pumps available and benefiting from exceptional energy savings in your production processes whilst reducing your overall carbon footprint.

The AVF-X Series features breakthrough designs focused on improving pump efficiency. Superseding the AMX range, the volute and impeller have been completely re-designed with a 3-Dimensional impeller and centreline volute casing to enable even longer service life whilst consuming less energy and reducing your running costs. With pumps accounting for half of all the energy consumed in an industrial plant, we believe that every pump should be reliable and efficient because if your pump doesn’t perform well, your plant won’t either.

The AVF-X Series of pumps handle highly corrosive or toxic chemicals for everyday applications. The sealless, magnetic-drive construction fully contains the chemical to prevent leakage and pollution of your work environment. Mag drive pumps work by using a magnetic coupling to transfer the mechanical energy from the motor to the pump's impeller. A drive magnet is attached to the motor shaft and on the pump side, an inner magnet is attached to the pump impeller. The magnetic flux between the drive and inner magnets pass through the pump containment shell, forming the magnetic coupling and allows the pump to be hermetically sealed for leak-free operation.

Reliability Redefined

Patented Run Dry Design

Under normal conditions, pumped liquid cools and lubricates the pump. But when starved of liquid, heat from friction can cause damage.

Crest Assoma’s Mag Drive range prevents this with a patented auxiliary circulation channel, cooling the bearing without reducing pump efficiency—even in dry-run scenarios.

For a smarter, more cost-effective solution, use our Life Cycle Cost (LCC) analysis to compare pump options and find the most efficient choice.

Frequently Asked Questions

What are magnetic drive pumps used for?

Magnetic drive pumps are used in a wide variety of applications, including chemical processing, water treatment, and metal finishing. They are designed to provide a reliable and efficient solution for transferring corrosive and hazardous liquids. The pumps are constructed with a non-metallic construction, making them ideal for use in highly corrosive and hazardous environments.

How do magnetic drive pumps work?

Magnetic drive pumps are centrifugal pumps that use a magnetic coupling to transmit power from the motor to the impeller. The drive magnet is mounted on the motor shaft that will connect by magnetic force to driven magnets contained within the pump. This type of pump is ideal for applications where leakage or contamination of the pumped fluid is a concern, as there is no mechanical seal or shaft seal to fail.

Understanding MEI for pumps Exceeding 0.7

Pumps are an essential part of many industries, and it is important that they operate as efficiently as possible. The Minimum Efficiency Index (MEI) is a metric used to measure the efficiency of a pump. MEI is particularly important for pumps exceeding 0.7 because it can help users save money on energy costs and reduce their carbon footprint.

What is the Minimum Efficiency Index (MEI) for Pumps?

The Minimum Efficiency Index (MEI) is a measurement of the efficiency of a pump. MEI is calculated by dividing the actual pump efficiency by the minimum efficiency for that type of pump. The minimum efficiency for each type of pump is set by the standards organizations such as the Hydraulic Institute and the European Union. The higher the MEI, the more efficient the pump is.

Why is MEI important for pumps exceeding 0.7?

MEI is particularly important for pumps exceeding 0.7 because it can help users save money on energy costs and reduce their carbon footprint. Pumps that exceed 0.7 are typically larger and more powerful, and they use more energy than smaller pumps. Therefore, even a small increase in efficiency can result in significant energy savings. In addition, using a more efficient pump can help reduce greenhouse gas emissions, which is an important consideration for many industries.

What are the benefits of using a pump with a high MEI?

Lower energy costs: Since a more efficient pump uses less energy, it can help users save money on energy costs.
Reduced carbon footprint: Using a more efficient pump can help reduce greenhouse gas emissions, which is an important consideration for many industries.
Improved reliability: A more efficient pump is likely to last longer and require less maintenance than a less efficient pump.
Better performance: A more efficient pump is likely to perform better, which can help improve overall process efficiency.
