Anti-corrosion industrial pumps suitable for pumping acids and bases fluids and highly corrosive liquids
The HTM PP/PVDF series magnetic drive centrifugal pumps are manufactured in thermoplastic materials ( PP and PVDF) and are specifically designed for handling chemicals and highly corrosive liquids.
Thanks to the advanced magnetic drive system, the HTM PP/PVDF pumps significantly minimize the risk of leakage and fugitive emissions, while also reducing overall maintenance costs.
Torque transmission occurs 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.
* 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.
* GemmeCotti supplied customized pumps with trimmed impellers based on the working point required by the customer. For any further information and quotation you can fill in the online form or send an email to info@gemmecotti.com. Our commercial office will select the pump suitable for your needs.
The HTM 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 HTM 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.
The oversized front bushing is designed to provide high resistance to axial thrust, improving mechanical strength and extending service life.
HTM pumps are equipped with NdFeB magnets, capable of generating high magnetic torque.
This configuration ensures efficient power transmission with no risk of magnetic decoupling under correct operating conditions.
The magnetic drive configuration provides several important advantages:
Unlike many centrifugal pumps available on the market, the 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 HTM magnetic drive centrifugal 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.
