Rotalution brand Pumps

Rotalution Brand type: MAGDRIVE- Magnetic Seal less centrifugal pumps.

Different Brands:

Rotalution has an extensive supply chain network in spare parts for pumps. 

There are many brands and types from all parts of the world, still existing or gone bankrupt, making it difficult to trace a pump back to the original or current supplier. Within our network we can always find either the part, pump or provide you with a suitable alternative.

We can make your work easy, don't waste precious time searching for a part.

Pump types we provide services for:

  • Oil lubrication pumps for gearboxes, compressors and turbines
  • Cooling water pumps for industrial- or power plants
  • Chemical substance pumps
  • Dry-dock pumps
  • Water management pumps
  • Boiler water feed pumps
  • Slurry pumps, like the Warman range


 

Pump and Electric Motor  Efficiency

 

A lot of the currently installed pumps in the industry today do not run at their best efficiency point. If the pump is completely off the curve, there can even be a lot of damage due to for instance cavitation.

Rotalution Focusses on these inefficient pumps. The cause can be found in a lot of areas, plants increase their capacity, Difference between calculated resistance and real life, different pumped product. These inefficiency’s waist a lot of energy, this is not necessary.

Case study:

 

Imagine a water pump with a power of 350 kW and a flow of 1500 m3/h. If the pump has the best efficiency point at for instance 1600 m3/m, it is easily more than 10% efficiency loss. If the pump runs 24/7 the waisted energy is: 22.26 MWh. Not only is this very bad for the environment, it is also destroying € 17.808,- per year (if 1 kWh = 0,08 euro, industrial pricing).

Many pumps we encounter even run worse than the 10% reduction in efficiency, do your math.

Our proposal:

Step 1: One of our experts measures all pumps in your plant with our US flow meter. We take the information from the pump and collect the available data from the customer (Pump data, running hours, etc.)

Step 2: We calculate the options. These options can be, adjusting/ renewing the impeller, adjusting the piping, replacing the complete pump (Wear and tear also changes the efficiency) or maybe even replacing the complete skid. (we also check the electric engine on efficiency, a lot can be gained there as well).

Step 3: We offer the complete scope we think is worth the investment. We calculate the savings for the coming years and the environmental benefits.

Step 4: If all in agreement, we execute the work, the complete scope with our professional service engineers.


Example of a pump efficiency curve, you can see the steep drop if the flow/ head changes.
