HTT – Magnetic drive turbine pumps in thermoplastic materials

HTT pumps are magnetic drive turbine pumps made of thermoplastic materials (Polypropylene and PVDF) suitable to transfer acids and corrosive liquids. These pumps have been designed with a sealless design where the pump is closed coupled to the motor and the motion occurs through magnetic joints. The external magnet, in fact, is mounted on the drive shaft and it transmits the motion from the motor to the internal magnet connected to the pump impeller which rotates and moves the fluid through the pump. It is the magnetic attraction between the external magnet and the internal magnet which allows the full torque of the motor to be passed to the impeller. The two magnets are separated by a rear casing that creates a hermetic containment of the liquid which has no access to the outside, thereby preventing any leakage of fluid or other fugitive dangerous emissions. Magnetic pumps require minimum maintenance with consequent save in terms of repairing and spare parts costs. HTT pumps handle 20% entrained gas and resist cavitation.

Mag drive turbine pumps model HTT are suitable to pump acids and highly corrosive liquids used in chemical industries, laboratories, biotechnology, pharmaceutical, metal finishing machines, petrochemical industries, sugar plants, textile industries,loading/unloading of tank trucks, graphics, heat exchangers, water treatment plants, filter units, galvanic industry, military industries, dairies, packaging industries and many more. These kind of pumps can easily handle acids without any problem of chemical corrosion such as for example: acetic acid, alcohol ethyl, ammonia, detergents, hydrochloric acid, hydrofluoric acid, phosphoric acid, sea water, sodium chloride, sodium hydroxide, sodium hypochlorite, sulfuric acid.
