The AME range are heavy-duty process pumps designed with a metallic armour and high purity PFA-lining to handle the toughest applications and for transferring high purity aggressive chemicals. Designed to ISO 2858 standards, these magnetic drive pumps are built for reliable and leak-free operation in the most arduous of applications with temperatures <150°C thanks to the patented structural design.

ROBUST DESIGN
Stop replacing pumps and start investing in performance.
The biggest concern with heavy duty seal-less pumps made from engineering plastic has been the shaft support system as it must be strong enough to withstand the radial forces during operation. The AME range is designed to balance radial force and reduce the bearing load which also reduces the noise level as a result. The AME mag drive range feature a patented, integrated ‘V’ shape front support that is integral to the metal casing which is then PFA lined. This improves the liquid flow to the impeller, increasing operational efficiency, reducing NPSHr and ensuring a long service life. The one piece PFA lining and internal SSiC parts give outstanding chemical resistance to practically all corrosive applications, even at temperatures up to 150°C.

Frequently Asked Questions
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.
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.
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.
