GemmeCotti European Pumps: HTM PP/PVDF Series for Corrosive Fluid Handling

What are the HTM PP/PVDF pumps

In a seal-less magnetic drive centrifugal pump the external magnet is connected directly to the motor shaft and it transmits the torque to the internal magnet. The magnetic field created produces a rotation without physical contact between the parts so the impeller spins and moves the fluid. The rear casing is placed between the two magnet joints and it hermetically closes the hydraulic part from the motor.

Main advantages of seal-less mag drive pumps:

• No mechanical seals
• Hydraulic part hermetically closed
• No leakage or emissions
• Low maintenance costs
• Long lifetime
• No need of motor/pump alignment
• Safe and reliable pumps

Mag drive pumps are the perfect solutions for chemical handling because they assure zero leakage and emissions.

These anti-corrosion industrial pumps are suitable for pumping acids, bases and highly corrosive liquids.

Features of HTM PP/PVDF Pumps by GemmeCotti European Pumps

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

Injection Moulding

• The plastic parts of HTM pumps are made by GemmePlast, a company belonging to the GemmeCotti group, which specializes in injection moulding for plastic materials. This allows for a careful quality check of the raw materials and the complete control of the entire moulding 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 avoids casing deformation under pressure.

Bushing

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

Static Shaft

• The static shaft of the HTM PP/PVDF series mag drive centrifugal pumps is made of Alumina 99.7% (Al₂O₃), an extremely resistant ceramic material, which guarantees the maximum stability and resistance to aggressive chemicals.

Magnets

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

HTM pumps are an ideal solution for reliable, leak-free performance in high-temperature environments. Their capability to manage aggressive chemicals while offering low-maintenance and efficient operation makes them well-suited for a wide range of demanding industrial applications.
