Mag drive regenerative turbine pumps series HTA GemmeCotti


Mag drive regenerative turbine pumps series HTA are made of AISI 316 or, on request, in other metallic materials (Hastelloy or Titanium) and are suitable for dangerous and inflammable liquids. Thanks to the innovative mag drive system, pumps model HTA reduce the risks of losses and the maintenance costs. The transmission of the motion occurs through magnetic joints without using mechanical seals. This guarantees the maximum hermetic safety and efficiency. The pumped liquid has to be clean and without solids in suspension.

Magnetic drive pumps have a particular sealless design that is suitable to pump corrosive and dangerous liquids thanks to the high chemical resistance and absence of leakage and emissions. The structure is really simple so that the pump requires a very reduced maintenance with consequent save in terms of repairing and spare parts costs during the pump life. The external magnet placed on the drive shaft transmits the motion to the internal magnet connected to the impeller which rotates and moves the fluid through the pump.

Typical applications:
▪ High corrosive liquids
▪ Toxic, noxious and carcinogenic liquids
▪ Hydrocarbons, pyrophorics and other flammables
▪ Heat transfer oils
▪ Refrigerants and cryogenics
▪ Radioactive liquids
▪ Handles up to 20% entrained gas, resists cavitation
