Anti-corrosion industrial pumps suitable for pumping acids and bases fluids and highly corrosive liquids
The HTM SS series magnetic drive centrifugal pumps are manufactured in AISI 316 stainless steel and are specifically designed for handling hydrocarbons, solvents and hazardous liquids.
Thanks to the advanced magnetic drive configuration, HTM SS pumps minimize the risk of leakage and fugitive emissions, while also reducing overall maintenance costs.
Torque transmission is achieved through magnetic couplings, eliminating the need for a mechanical seal. This sealless design ensures maximum operational safety and high efficiency, even in demanding applications.
For correct operation, the pumped liquid must be clean and free of suspended solids, as the presence of particles may damage internal components.
The HTM SS 316 series is also available in ATEX version for Zone 1 and Zone 2 (pump model EM-C).
* 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 SS 316 pumps are manufactured in AISI 316 stainless steel, ensuring excellent mechanical strength and corrosion resistance.
This material provides high compatibility with acids, alkaline solutions, chemicals and hazardous fluids, making the pumps suitable for demanding industrial environments.
Unlike many centrifugal pumps on the market the pump head of GemmeCotti pumps is fixed to the bracket with 8 bolts. This feature guarantees a firm fastening of the pump head to the bracket and avoid the casing deformation under pressure.
The static shaft used in HTM SS 316 magnetic drive centrifugal pumps is manufactured in Hastelloy C276 (HC276), a nickel-based alloy known for its exceptional resistance to highly aggressive chemicals and severe operating conditions.
This material ensures maximum structural stability and superior corrosion resistance.
The magnetic drive configuration provides several important advantages:
The oversized front bushing is designed to provide high resistance to axial thrust, improving mechanical strength and extending service life.
HTM SS 316 pumps are equipped with NdFeB magnets, capable of generating high magnetic torque
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.
