Magdrive and mechanical seal industrial pumps
Horizontal and vertical centrifugal pumps

HTN are close-coupled single-stage magnetic drive regenerative pumps. The pump casing is made from one-piece machined thermoplastic thus guaranteeing exceptional mechanical strength. The remaining components in contact with the pumped liquid are made from injection-moulded thermoplastic. The Neodymium-Iron-Boron rare-earth magnets guarantee a compact coupling that is efficient even with high-density liquids. The use of rotary LF graphite and static ceramic bushings guarantees excellent value for money. On the other hand, the pure Silicon Carbide version allows use with particularly corrosive liquids. Motion is transmitted by magnetic couplings, thus avoiding a mechanical connection between impeller and the driving part. This system guarantees maximum safety, reducing the risk of leakage to a minimum. Furthermore, the elimination of external transmission parts makes this series extremely compact, silent and safe even for inexperienced operators. The special characteristics of these pumps are: low flow and high head, possibility of pumping liquids containing up to 20% gas, lower suction head requirement than a centrifugal pump, processing of clean liquids only.

HTN pumps are mainly intended for builders of small systems, OEM users and all those applications where the use of conventional centrifugal pumps is not recommended.
