Magnet Drive
KLAUS UNION MAGNET DRIVE
Sealless Technology
If pumps are used to handle dangerous products, it is essential to avoid even the smallest leakages into the environment in order to ensure the protection of both people and the atmosphere. The ideal solution for such a case is pumps with magnet drive. The first of its kind was introduced by Klaus Union in 1955.
Technical Description
In a magnetic drive pump, the drive shaft – to transfer the mechanical energy from the drive to the pump hydraulics – is not a single shaft with a gland packing or mechanical seal on it. Instead, the energy is transferred contactless from the drive shaft to a pump shaft, using a magnetic coupling. The drive shaft connects the motor with the outer magnet carrier, while the pump shaft holds the inner magnet carrier and the impeller. Both magnet carriers are fitted with permanent magnets, on the inside and the outside respectively. Due to the rotation of the outer magnet carrier, the inner magnet carrier is rotated synchronously via magnetic forces; the mechanical drive energy is transmitted.
Between the magnet carriers, the so-called containment shell is installed to separate the pumped fluid from its environment. The pump shaft is supported by fluid-lubricated maintenance-free slide bearings within the pump’s hydraulic system. There are no dynamic seals between the pumped fluid and the environment from which leakage can escape. Only two static seals are used between pump casing and casing cover and between casing cover and containment shell in the magnetic drive pump.
Advantages vs. Mechanically Sealed Pumps
- Nearly maintenance free
- Less investment costs and less maintenance costs
- No instrumentation or special monitoring devices required in standard
- No utilities required, such as nitrogen or cooling water
- No leakage to the atmosphere
- No loss of sealant liquid
- No wear of the seals at all
- Low mechanical loads on shaft and bearings
- High stiffness of the pump shaft
Advantages vs. Canned Motor Pumps
- Standard IEC and NEMA motors can be used
- Lower investment and repair costs
- Separate flushing of journal bearing
- Higher efficiency
- Use of non- metallic containment shell possible
- No heat generation of the rotor by electric losses
- Higher viscosities possible
- Higher temperatures without cooling possible
- No special monitoring devices necessary
Technical Developments
TECHNICAL DEVELOPMENTS
KLAUS UNION NO VISCO® BEARINGS
Our new NoVisco® bearings can handle extreme solid loads and require no hydrodynamic lubrication film. Thus they do not require any minimum viscosity whatsoever.
This enables Klaus Union pumps to handle applications reliably and without the use of any utilities which were previously impossible to handle reliably with magnetic coupled pumps.
PULLOUT DESIGN FOR VERTICALLY SUSPENDED (SUMP) PUMPS WITH MAGNET DRIVE
Clean and safe maintenance of vertically suspended (sump) pumps with magnet drive
TEMPERATURE MONITORING SYSTEM (TPX)
To further optimize the process reliability of Klaus Union’s magnetically coupled pumps, the TPX temperature monitoring system enables accurate and instantaneous measurement of the containment can temperature.
HYBRID DOUBLE CONTAINMENT SHELL
To reduce the heat generated by a purely metallic, double containment shell and at the same time to improve the overall efficiency of the pump, Klaus Union has developed and patented a new hybrid double containment shell.
Secondary mechanical seal
Secondary mechanical seal as a cost efficient additional layer of safety for magnetic coupled pumps in particularly hazardous applications.
Non-Metallic Containment Shells
Through the use of non-metallic containment shells instead of the traditionally used metallic containment shells, Klaus Union eliminates eddy current losses and increases the efficiency of magnet drive pumps significantly.
Dry Running Design
For the case of a flow interruption, Klaus Union has developed the RTZ Design for magnet drive centrifugal pumps.
Pumps according to this special design conveying water-like media can handle a dry run on suction side for up to 10 minutes. The increase of the containment shell surface temperature is relatively slight.
Handling Liquids Containing Solids
Available design features for magnetically coupled centrifugal pumps to safely handle liquids containing solids.
Greased-for-life Lubrication
Effective from August 1, 2016, Klaus Union offers greased- for-life antifriction bearings (2Z/WT: two sealing discs) for pumps with grease lubricated drive frame as a standard.
The upgrade does not incur a cost adder. It provides various benefits for customers.

DESIGN VARIANTS The pumps are outfitted with a heat jacket and pump casing (H1) and/or a heat jacket in the bearing lantern (H2). Both heat jackets can be realized either separately or in conjunction with a bypass line. The heat jackets in the standard construction are rated for operating pressure of 16 bar at 200 °C (steam) or 6 bar at 350 °C. The heat jackets can also be used for cooling. Inducers are often used in cases where the installation’s NPSH values are extremely low. Inducers substantially reduce pump NPSH throughout the installation without altering pump characteristics.

NACHSETZZEICHEN (AUSFÜHRUNGEN): DESIGN VARIANTS The pumps are outfitted with a heat jacket and pump casing (H5) and/or a heat jacket in the bearing lantern (H2). Both heat jackets can be realized either separately or in conjunction with a bypass line. The heat jackets in the standard construction are rated for operating pressure of 16 bar at 200 °C (steam) or 6 bar at 350 °C. The heat jackets can also be used for cooling. The thermal barrier acts as a structural element between the bearing carrier (in the bearing carrier model) or drive motor (in the close coupled model), whereas the hydraulic system allows for heat transfer. This reduces ball bearing temperatures in the gearing when hot liquids are being transported. A radial shaft sealing ring can also be integrated into the thermal barrier for purposes of sealing the magnet driver. The sealing ring acts as a secondary seal that prevents the product from leaking into the environment through a leak in the isolation shell. In order for this secondary seal to be used, the magnet driver chamber must be monitored so that leaks can be detected in good time. The double isolation shell should be used in situations requiring a high level of safety. The unit consists of two interlocking isolation shells, both of which are rated for the relevant operating conditions. If one of the two units is damaged, the casing still remains leaktight. The gap between the two units can be monitored. Flow Rate

The heat jackets in the standard construction are rated for operating pressure of 16 bar at 200 °C (steam) or 6 bar at 350 °C. The heat jackets can also be used for cooling. When solids-containing liquids are being transported, the internal filter prevents inadmissibly large particles from entering the flow channels, and from there the magnetic coupling and internal bearings. These external connections allow for external flushing, feeding and/or venting. Connection E1 is used in situations where a continuous feed into the magnet drive is desired. Connection E2 is used suitable for short-term flushing, or for external venting of the magnetic coupling. The double isolation shell should be used in situations requiring a high level of safety.
