Our HTM PP/PVDF series mag drive centrifugal pumps are made of thermoplastic materials, Polypropylene (PP) and PVDF, ideal for handling aggressive chemicals and corrosive liquids.

Featuring an innovative sealless magnetic drive, these pumps eliminate leakage and emissions, significantly reducing maintenance costs. Motion is transferred via magnetic couplings, ensuring maximum safety and efficiency.

Our HTM PP/PVDF series pumps feature NPT or BSP connections and are designed for use with NEMA motors (operating at 60Hz) or IEC motors.

TECHNICAL DATA

HTM-PERFORMANCE-CURVES-60HZ

* 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.

TECHNICAL DATA

* 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.

STRONG POINTS OF HTM PUMPS

HTM80-HTM100-pp-pvdf-mag-drive-centrifugal-pumps

MANUFACTURING MATERIALS

HTM pumps are made of thermoplastic materials PP o PVDF and they are compatible with most acids and basic liquids, chemicals and other dangerous fluids.

LEAK FREE MAGNETIC DESIGN

Advantages of magnetic drive pumps:
– sealless design
– no leakage and emissions
– no motor/pump alignment
– environmental sustainability
– reliability and safety
– limited periodic maintenance with long-term savings

INJECTION MOULDING

The plastic parts of HTM pumps are made by GemmePlast, a company belonging to the GemmeCotti group, which is specialized in the injection molding for plastic materials. This allow for a careful quality check of the raw materials and the complete control of the entire molding process.

RELIABILITY

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.

 

BUSHING

The large size of the front bushing used ensure high resistance to axial thrust.

STATIC SHAFT

The static shaft of the mag drive centrifugal pumps HTM series are made of Alumina 99,7% (Al2O3), an extremely resistant ceramic material, which guarantees the maximum stability and resistance to aggressive chemicals.

MAGNETS

The HTM pumps are equipped with NdFeB magnets that ensure a high magnetic torque. No risk of magnets decoupling

SEALLESS MAGNETIC DRIVE DESIGN

Magnetic drive pumps are designed with a special sealless configuration that is suitable for transferring acids, chemicals, corrosive and dangerous liquids thanks to the high chemical resistance of their construction materials and to the absence of leakage and emissions. The structure is really simple and it requires very little maintenance with consequent saving in terms of repairing, spare parts and machine downtime (costs during the pump life).  This type of pump is not suitable for transferring liquids with solids.  Perfect solution for aggressive liquids.

OPTIONAL

FLANGES

On request GemmeCotti provides DIN e ANSI flanges for thermoplastic pumps (flat stub + slip-on flanges) and welded DIN o ANSI  flanges for pumps in AISI 316.

More informations about flanges

BASEPLATES

GemmeCotti baseplates are suitable for pump completed with motor with B3/B5 configuration. They allow the correct positioning of the pump.
