HTM SP: OUR NEW MAG DRIVE CENTRIFUGAL PUMP SELF-PRIMING

HTM SP mag drive centrifugal pump self-priming

We are extending our product line: our new pump is ready!

We are happy to announce our new mag drive centrifugal pump self-priming HTM SP!

GemmeCotti HTM SP pumps combine the typical features of our mag drive centrifugal pumps with the self-priming capability. These pumps can prime up to 6 meters at sea level.

MAIN FEATURES

MATERIALS

HTM SP pumps are made of Polypropylene (PP), a thermoplastic material that ensures the best resistance to most chemicals.

All the internal plastic parts are obtained through the injection moulding process that we directly manage in our sister company Gemme Plast.

PERFORMANCE CAPABILITY

The new magnetic centrifugal pump self-priming HTM SP can reach a capacity of 25 m3/h and a head of 22 m.

The suction connection of this pump can be customized in 3 welded configurations according to your needs (frontal, on the right and on the left).

MAGNETIC DRIVE PUMP SYSTEM

Mag drive pumps have a special sealless design that is suitable for pumping corrosive and dangerous liquids thanks to the high chemical resistance and to the absence of leakage and emissions. The structure is really simple and it requires very little maintenance with consequent savings in terms of repairing, spare parts and machine downtime costs during the pump life.

In magnetic pumps, there is an external magnet which is connected to the shaft of the electric motor.
The synchronous motion is transmitted from the motor to the rotor (consisting of the internal magnet and the impeller) through the external magnet. The two magnets never come into contact, they are moved by the magnetic field only. The impeller connected to the internal magnet spins around a static shaft and the liquid moves through the pump. The whole hydraulic part is hermetically sealed: in the space between the magnets there is a rear casing which closes on the pump head and prevents the pumped liquid from coming out of the pump.

The pumped liquid must be clean, without solids in suspension (max. quantity of solids: max 2% – max 1mm).

HTM PP PVDF NOW AS THEN: THE 7 STRONG POINTS OF OUR BEST-SELLER SERIES

Since 1992 GemmeCotti has been manufacturing several types of high quality chemical pumps suitable for most industrial applications.

Everyday we employ all our experience to improve the existing products and to design new projects in order to satisfy our customers’ needs. We live in the present and we design the pumps of the future without forgetting where we started.

The magnetic drive centrifugal pump HTM PP/PVDF was our first product, the one which made us experts in the field of the pumping solutions.

HTM 10 mag drive centrifugal pump

Over the years we developed the series that now includes 9 sizes: HTM 4, HTM 6, HTM 10, HTM 15, HTM 31, HTM 40, HTM 50, HTM 80, HTM 100. Each size is available in two thermoplastic materials: PP (polypropylene) and PVDF.

The HTM are high-quality pumps, extremely reliable and versatile, and they are still our bestsellers.

Which are the 7 strong points of these mag drive centrifugal pumps?

1. MATERIALS OF CONSTRUCTION

The HTM pumps are manufactured in thermoplastic materials, PP or PVDF. These anti-corrosion materials are compatible with the great majority of the acids, chemicals and dangerous liquids.

Check the chemical compatibility chart

2.INJECTION MOULDING

The plastic parts of our HTM are manufactured by Gemme Plast, another company in the GemmeCotti group, which is specialized in the injection moulding of plastic. Thanks to this cooperation, we can check all the raw materials used and we have total control over the moulding process.

3.LEAKLESS MAGNETIC DESIGN

Advantages of the magnetic drive system:

  • no mechanical seal
  • no leakage or emissions
  • no waste of liquidsHTM magnetic drive system
  • environmental sustainability
  • reliability and safety
  • low maintenance and consequent long term savings
  • no need for a pump-motor alignment

Please note that the liquid must be clean and without solids in suspension (acceptable quantity and dimensions of the solids: max 2% – max 1mm).

Discover more about the mag drive advantages

4.RELIABILITY

Unlike most centrifugal pumps on the market, the pump head of the HTM is secured to the bracket with 8 bolts. This feature allows the safe fastening of the pump head, ensuring the static seal and avoiding the deformation of the pump head due to the pressure.

5.BEARINGS

The wide dimensions of the frontal bearings ensure the high resistance to the axial thrusts.

6.STATIC SHAFTHTM magnet and shaft

The static shaft of the mag drive centrifugal pumps HTM is made of alumina (Al2O3), an extremely robust ceramic material that ensures great stability and resistance to most hazardous liquids.

7.MAGNETS

The HTM pumps series are equipped with a high magnetic coupling created with magnets made of NdFeB. Thanks to this particular feature, the internal and external magnets won’t detach from each other while the pump is operating.

HTM 100 PP/PVDF: our biggest mag-drive centrifugal pump is now available

 mag-drive centrifugal pump HTM 100

Just two months ago we had the pleasure to introduce to you our new magnetic drive centrifugal pumps HTM 80 as one of the biggest pumps with injection moulded parts in the market. But now we are getting even bigger! GemmeCotti’s mag-drive centrifugal pumps series HTM has indeed another new entry: the HTM 100 PP/PVDF. Just as her little sister HTM 80, mag-drive pump HTM 100 PP/PVDF is not machined from a block and it can reach a capacity of 130 m3/h and a head of about 50 mlc.

MAIN FEATURES

Performance capability:

HTM 100 is the new king size of our best seller series HTM. This centrifugal pump series, that now counts 9 sizes of pumps, can cover a range of flow from 0,5m3/h to 130m3/h and a range of head from 0,5mlc to 48mlc.

Materials:

As all our HTM pumps, HTM 100 is available in thermoplastic materials (PP or PVDF). These materials grant the best resistance to a lot of existing chemicals. You can find a useful compatibility guide here to find out which material better fits your liquid. Moreover, in HTM 100 all the internal plastic parts are obtained through the injection moulding process that we directly manage in our sister company Gemme Plast

Mag drive design of HTM 100:

The special design of our mag-drive centrifugal pumps without any mechanical seal has a lot of advantages, such as the prevention of any leakage of fluid and fugitive emissions, the very low maintenance and the easiest possible assembly process.

Magnetic drive pump functioning:

How does the HTM 100 work? Thanks to our magnetic drive technology it is very simple to explain. An external magnet located on the drive shaft transmits the motion to the internal magnet, that is connected to the impeller. The impeller rotates and moves the fluid through the pump. Isn’t it really easy? Furthermore, the two magnets are separated by the rear casing that creates a hermetic container for the liquid, avoiding any access from the outside.
