MAG-DRIVE CENTRIFUGAL PUMPS
SEAL-LESS MAG DRIVE CENTRIFUGAL PUMPS

In seal-less magnetic drive centrifugal pumps, the external magnet is directly connected 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. Three different models of mag drive centrifugal pumps:

HTM PP/PVDF

 MECHANICAL SEAL CENTRIFUGAL PUMPS

Mechanical seal centrifugal pumps are the right solution for applications involving solids in the liquid because their design with open impeller allows to pump dirty liquids and fluids with high viscosity. The seal in mechanical seal pumps is composed by a static ring and a rotating ring placed on the pump shaft which is directly coupled to the motor shaft. The two surfaces sliding together need to be lubricated and the seal lubricant is the liquid itself that is being pumped.

• Thermoplastic pumps made in PP or PVDF.
• Capacity up to 58 m3/h.
• Head up to 38 mlc.
• Two different kind of mechanical seal available: lip seal for model HCO 95-10, internal PTFE bellow mechanical seal for all the other pump sizes.

 LIQUID RING VACUUM PUMPS

VPM (magnetic drive design)

VPM range: Sealless pump, magnetic drive. Support is guaranteed by standard design of silicon carbideslide bearing.

VPS (close coupled with mechanical seal)

VPS range: available in close coupled design and fitted with single mechanical seal. Supported by means of standard bearings fitted to the electric motor.

VPL (long coupled with mechanical seal)

VPL range: Standard execution with single mechanical seal. For more arduous duties it is also possible to install a double mechanical seal with an external flushing system. Support by a robust bearing bracket complete with sealed for life ball bearings. We can also install an oil lubricated ball bearing design for this construction if requested.

Our liquid ring vacuum pumps types VPM, VPS, and VPL, are constructed in a conventional overhung impeller design. They are suitable for operating with both toxic ad dangerous gases. GEMMECOTTI liquid ring vacuum pumps attain high levels of vacuum by means of isothermal compression. They can evacuate most gases and vapors and are especially suitable for the evacuation of gases containing both condensate and liquid compositions for arduous applications. GEMMECOTTI liquid ring vacuum pumps generally operate without contact between internal rotating parts, with the exception of the mechanical seal rings for pumps VPS and VPL and the rotating bushes for pump VPM (magnetic drive). Due to their inherent design, contact is required, however, the service liquid ensures that both the mechanical seal and bushes are lubricated sufficiently in these designs. VPM, VPS, and VPL models are also capable of operating without the need for an external lubrication source, as the standard design uses sealed for life bearings. Vibration and noise levels are minimized and fall well below industry requirements on all models within the range. VPM, VPS and VPL have the capability to incorporate automatic drain and anti-cavitation valves

 MAG DRIVE CENTRIFUGAL PORTABLE PUMP

The new pumping system for IBC tanks is a portable device composed of a mag drive centrifugal pump series HTM PP/PVDF, placed in a frame that can be easily moved.The peculiarities of this system are that it is flexible for different uses, and it is portable. In fact the pump, placed in a proper structure, can be removed from an IBC container’s attack and connected to another, thanks to quick couplings, ensuring anyway all of its functionalities. The displacement of the pump is easy and rapid, as a result of its compact shape and its practical handles, located on the top. The system includes a control panel composed by illuminated start and stop pushbuttons, a red LED for power on, an emergency stop button with manual restoration and a flexible supply cable with CEE plug. There is also a specific container in order to collect dropping fluid. As an optional, it is possible to order a dry running protection device.

 ACCESSORIES

The installation of W-01 Emirel prevents expensive damage to pumps because it avoids the dryrunning working, the closed discharge and the blocked suction. We recommend the use of this instrument to unload tank truck or every other application when it’s not certain if the liquid is constantly present in the pipes. This device checks constantly the active power of the motor, that is the medium value of the instantaneous power absorbed by the pump, through the reception of information about the voltage and about the voltage variations. Through a set point and a timer, which are adjustable, it’s possible to set the minimum power and the triggering time of the device. If the power goes under the established value, the pump stops and the device must be switched on again manually. In case of continuous intervention on the apparatus, check the presence of liquid and/or the correct functioning of the plant to find the cause of working of the device.
