A. Rigid Shaft Support Traditionally, plastic chemical pumps either have a single sided shaft support or only use plastic for a double-ended shaft support. The problem with this is that under high temperature or pressure, the shaft support weakens resulting in shaft deflection and therefore vibrations leading increased wear and reduced service life. The AME range features a patented integral V shape front support that is part of the metal casing armour and then PFA lined. The rear of the shaft is supported in the PFA lined containment shell and reinforced by a metal support ring and high-strength carbon fibre composite cover. This superior design means a longer design life resulting in far less downtime and increased productivity.
B. Vacuum Resistant Lining The PFA lining is formed directly onto the metal armour and designed to ensure the PFA material remains adhered to the armour even under low absolute pressure.
C. Load Balanced Volute The casing volute is designed to have an evenly distributed hydraulic pressure, providing a balanced radial loading on the impeller.
D/E. One piece, metal embedded impeller Traditionally, an ETFE or PFA mag drive pump will be fitted with a separate impeller and inner magnet. In applications of high pressure or temperature, the impeller can deform resulting in damages and reduced performance. The AME pump range is built whereby the impeller and magnet capsule are formed as one piece which eliminates the possibility of the impeller loosening. For further operational stability and rigidity, a metallic structure is embedded from the magnet capsule to the impeller blade further increasing the pump’s operational life.
F. Simple Construction The stationary shaft design allows for a very simple construction which makes maintenance and repairs very simple.
G. Reinforced Containment Shell The plastic containment shell is reinforced with a carbon fibre composite cover. There is no eddy current loss, so no additional heating of the pumped chemical.
H. High Strength Magnetic Coupling Inner magnets are constructed from Samarium Cobalt (SmCo) in order to withstand high operating temperatures without experiencing demagnetization. High strength neodymium (NdFeB) is then used for the drive magnet to provide high torque transmission.
I. Back Pull-Out Simple and quick maintenance access without the need to remove the pump casing from the piping.
J. ISO Standardised Designed to ISO 2858, ISO 5199, ISO 15783, and EN 809 standards.
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.
