HTM-SP pumps combine the typical features of our mag drive centrifugal pumps with the self-priming capability. At sea level these pumps can prime up to 6 meters. HTM-SP pumps are made of Polypropylene (PP) or PVDF, a thermoplastic material that ensures the best resistance to most chemicals. Thanks to the innovative sealless magnetic drive system, the pump model HTM-SP guarantees the maximum safety and efficiency, reducing the risks of leakage and emissions in the environment and the maintenance costs. The pumped liquid has to be clean, without solids in suspension.

TECHNICAL DATA

* 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.

MANUFACTURING MATERIALS

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

LEAK FREE MAGNETIC DESIGN

Advantages of the magnetic drive design:
no mechanical seal
no loss of liquids and emissions
no motor/pump alignment
environmental sustainability
reliability and safety
limited periodic maintenance
long-term savings

INJECTION MOULDING

The plastic parts of HTM-SP 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 HTM-SP 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.

 

SELF-PRIMING ABILITY

HTM-SP pumps can prime up to 6 m at sea level liquids with specific gravity 1 and at room temperature.

STATIC SHAFT

The static shaft of the mag drive turbine pumps HTM-SP 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-SP pumps are equipped with NdFeB magnets that ensure a high magnetic torque

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.  Liquid must necessarily be clean and free of suspended solids (max presence of solid admitted: max 2% – max 1mm).
