Anti-corrosion industrial pumps suitable for pumping acids and bases fluids and highly corrosive liquids
The HTT series magnetic drive regenerative turbine pumps are manufactured in thermoplastic materials (Polypropylene – PP and PVDF) and are specifically designed for handling highly corrosive liquids.
Thanks to the advanced magnetic drive system, HTT pumps significantly reduce the risk of leakage and fugitive emissions, while also lowering overall maintenance costs.
Torque transmission is achieved through magnetic couplings, eliminating the need for a mechanical seal. This sealless configuration ensures maximum operational safety, high efficiency and reliable performance.
For correct operation, the pumped liquid must be clean and free of suspended solids, as the presence of particles may compromise internal components and pump functionality.
* The head and flow of the pump refer to the performance with water at room temperature. Should liquids at high temperatures and with high viscosity and density be pumped the performance has to be calculated accordingly. The electric motor should be selected on the basis of the viscosity and the specific weight given by the customer.

The HTT series pumps are manufactured in thermoplastic materials (PP or PVDF), offering excellent compatibility with acids, alkaline solutions, chemicals and hazardous fluids. These materials ensure high corrosion resistance and long-term durability in aggressive environments.
All thermoplastic components of the HTT pumps are produced by GemmePlast, a company within the GemmeCotti Group specialized in plastic injection moulding.
This internal production structure allows strict quality control of raw materials and full supervision of the entire moulding process, ensuring consistent product quality.
In the HTT series regenerative turbine pumps, the suction and discharge connections can be reversed simply by changing the motor rotation direction.
This feature provides greater installation flexibility and simplifies integration into existing systems.
HTT pumps are equipped with NdFeB (Neodymium-Iron-Boron) magnets, capable of generating high magnetic torque.
The magnetic drive configuration provides several important advantages:
Unlike many pumps available on the market, the pump casing (pump head) of GemmeCotti pumps is secured to the bracket using 8 fixing bolts.
This reinforced fastening system guarantees solid mechanical stability and prevents casing deformation under pressure.
The static shaft used in HTT magnetic drive turbine pumps is manufactured in Alumina 99.7% (Al₂O₃), a highly resistant ceramic material.
This ensures maximum structural stability and excellent resistance to aggressive and corrosive chemicals.
Magnetic drive pumps are engineered with a dedicated sealless configuration, making them ideal for handling acids, chemicals, corrosive and hazardous liquids. Their suitability for aggressive media is ensured by the high chemical resistance of the construction materials and by the complete elimination of leakage and fugitive emissions.
The design is mechanically simple and highly reliable, requiring minimal maintenance and allowing significant savings throughout the pump’s lifetime in terms of repairs, spare parts and reduced machine downtime.
This pump technology is not suitable for liquids containing solids. The pumped fluid must always be clean and free of suspended particles to ensure proper and safe operation.
For over 30 years GemmeCotti has been designing and manufacturing chemical pumps for acids, aggressive and corrosive liquids.
