Anti-corrosion industrial pumps suitable for pumping acids and bases fluids and highly corrosive liquids
The HTT-SP pumps are capable of self-priming up to 5 meters with water at ambient temperature.
The pump casing is machined from a solid PP block, ensuring high mechanical strength, while the impeller is manufactured in PVDF to provide maximum chemical resistance.
The casing construction from solid material guarantees superior structural robustness. The PVDF impeller is dynamically self-balanced, reducing axial loads and minimizing thrust bearing wear. Its independent design also simplifies servicing operations and helps lower maintenance costs.
This pump configuration offers excellent durability and high resistance not only to aggressive process fluids but also to external corrosion. It can handle fluids containing up to 20% entrained gas and provides strong resistance to cavitation phenomena.
* 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-SP 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.
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-SP 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.
The HTT-SP pump casing is machined from a solid thermoplastic block, ensuring high mechanical strength and structural rigidity.
This construction provides excellent resistance to process fluids as well as to external corrosion, making the pump suitable for demanding industrial environments
Advantages of magnetic drive pumps:
The HTT-SP series features integrated self-priming capability, allowing the pump to prime up to 5 meters at sea level, with liquids having specific gravity 1 at room temperature.
This makes the pump suitable for applications with suction lift conditions.
HTT-SP 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.
