herborner.F 100 % Coating = 0 % Corrosion!

A global innovation sets benchmarks: optimum protection against rust The herborner.F, with its coating thickness of up to 1000 µm, ensures for extremely smooth surface. This increases hydraulic efficiency by up to 10%, saving energy for years. All surfaces which come in contact with the pumped medium are sealed and protected. Sealing is achieved with a special HPC coating applied using a special method. This unique 100% coating is suited especially for use in swimming complexes, leisure and adventure pools and other theme parks. In addition, it is used in areas where a perfectly clean...

Efficiency comparison Coated pump Uncoated pump Thanks to the 100% coating, frictional losses are so low that up to 10% greater efficiency is achieved. The energy savings made during continuous operation mean that cost-effectiveness levels are particularly high. When using a pump with 22 kW, this would effect a saving of up to 2.2 kW/h. Optimised for servicing and maintenance Start-up safety All of the components were developed for optimum servicing and maintenance and put together intelligently. This means that work is significantly reduced for the required pump usage. When needed, easy...

equipment Service and maintenance Only stainless steel screwed connections are used, allowing trouble-free maintenance of components for years. Corrosion protection and protection against aggressive media thanks to the 100% coating of all relevant parts at risk from corrosion and that come in contact with the medium. Corrosion damage to the pump or system components is thereby prevented. Fortified bearings as standard An extended service life is achieved through liberally dimensioned shafts and fortified bearings. The 4-pole motors are also equipped with a relubrication unit from 1.1 kW.

Impeller protector Special impeller protector made of highly durable plastic protects the impeller from seizing up due to corrosion (after standstill periods) and ensures that the pump runs quietly. The version with a particularly small gap achieves high efficiency. Motor shaft The rigid motor shaft made from high-alloy stainless steel ensures minimal deflection. In this way, seal leaks can be minimised and the service life of the motor shaft increased. Impellers Dynamically balanced, closed multi-channel impellers make sure running is vibrationless and contribute to the long service life...

IE3-Motor The coated, close-coupled centrifugal pump herborner.F has an IE3 motor as standard. All the typical features of this series lead to energy savings and thus also to a noticeable cost reduction. Classification of electric motors In 2011, a new efficiency definition (IEC code) came into effect to which three-phase asynchronous motors must conform. The new standards are applied globally in order to be able to give a uniform assessment of motors. Since 2017, motors have had to conform to at least IE3 unless they are considered to be an exception, such as submersible motors. Motor A...

Comparison of the efficiency of IE2 to IE5 motors The graph clearly shows that it makes sense for pool operators to use efficiency-optimised motors because the power range of the pump is more often in the lower power range of the motor. Energy classification of electric motors IEC energy class Ultra premium efficiency Super premium efficiency SUPER Premium Premium efficiency NEMA Premium High efficiency Standard efficiency Below standard efficiency Comparison of old EFF code, new IEC code and NEMA (North America).

PM-Motor The coated, close-coupled centrifugal pump herborner.F-PM has a permanent magnet motor (PM). Compared to conventional asynchronous motors, PM motors (synchronous motors) achieve efficiency improvements of up to 13%. This leads to significant energy savings and thus also to a noticeable reduction in costs. Protection type Motor A permanently energised surface-cooled sync hronous motor is used. The motors cont i nu o u s l y a c h i eve t h e m oto r eff i c i e n c y of energy class IE5. Synchronous motors re quire a frequency converter in order to operate because they cannot start...

Comparison of the efficiencies The pump curve shown in the diagram with 3 kW drive output compares the electrical power consumption (efficiency) of the PM motor with an asynchronous motor. The PM motor has a considerably lower power consumption. Efficiency of asynchronous motor Calculation of the efficiency at Q = 120 m³/h P = U * I * cosφ * √3 PAsynchronous = 401.9 x 6.83 x 0.79 x 1.73 = 3.75 kW PPM = 330.0 x 5.73 x 1.0 x 1.73 = 3.27 kW Savings = 0.48kW = 12.8% Advantages of PM motors: More performance due to very high efficiency Reduced operating costs due to high energy savings Reduced...

C-Motor The coated, close-coupled centrifugal pump herborner.F-C has a heat exchanger motor (C). The energy re-use principle of heat exchanger motors leads to considerable savings in heating costs and heat reduction of the plant room, by supplying the motor's waste heat directly to the swimming pool water for heating. In addition, these motors are characterised by lower noise emissions. Protection type A medium-cooled heat exchanger motor is used. This returns a large proportion of the motor's waste heat back to the medium via an integrated cooling system through which the medium is guided....

Comparison of the noise emissions Reduction of the noise emissions for heat exchanger motors Heat exchanger motors not only save energy costs, but are also generally quieter by more than 10 db(A) compared to conventional air-cooled motors, as shown in the graph here to the side. This corresponds to a halving of the noise level. This makes these motors an attractive option for sensitive applications, such as in hotel systems. Use of heat exchanger motors means environmental protection Air-cooled motor Heat exchanger motor Dishwasher In general when compared to standard motors, heat exchanger...

Accessories Seal-Guard-System The Seal-Guard-System prevents dry running of the mechanical seal by means of a reserve medium supply. As soon as the primary mechanical seal in a pump is not in contact with the medium (a situation which subsequently would result in dry running), the reserve medium supply compensates for this insufficient lubrication. The medium supply is introduced into the pump back wall and is sealed on the drive side against the motor by means of a further secondary mechanical seal. You can also see from this tank if the primary mechanical seal is leaking. This system is...
