In the process industry there is a wide choice of types of pumps. Depending on the process for which the pump is used, the selection is limited. When a pump is used for dosing additives, for example, or for pumping water, the choice will quickly fall to gear pumps or centrifugal pumps respectively.
Centrifugal pumps are traditionally driven at speed. To achieve the desired volume flow, the pressure line is pinched. This is best compared to a garden hose that is connected to the tap, where the tap is fully opened and the hose is then pinched so that only a small stream of water comes out. This creates a higher pressure in the pipe that would not actually be necessary if the tap were to be opened only a little. At that moment, the pressure (and therefore the problem) is moved to the tap.
In fact, a lot of energy is used to build up a pressure, which is not necessary for a small stream. In this way, a lot of energy is wasted during the life of the pump over many years, because centrifugal pumps often have large installed capacities. 100 - 350 kW is not unusual. There's a lot to save here.
The speed of gear pumps is often controlled via frequency conversion of the e-motor. The speed of the gear pumps is adjusted with a flow meter or a "load cell" and a closed-loop control in such a way that the pump delivers the desired volume flow. Here, dosing accuracies of 0.1 ... 5% can be achieved. As a result, no more pressure is built up than necessary and much more efficient and energy-efficient pumping can be done.
The gear pumps that Suurmond supplies all have relatively small installed capacities. These typically vary between 0.2 kW and 18.5 kW! In short: the gear pump solution offers significant energy savings over centrifugal pumps.
Where centrifugal pumps often have large installed capacities, gear pumps are all very effective and efficient! Do you want to limit your CO2 emissions and save on energy costs? Then gear pumps are the best choice.
This new MAAG pump series, called “FQ” – ‘quick cleaning’ version, is being released for the production facilities with a constant need to clean and wash the transfer line at the end of each production batch, use different colours, use different additives etc. The pump can be disassembled quickly without needing to dismantle the drive shaft from the drive motor and the seal.
This feature can be applied on the existing pump series - CX, TX, FX, DX by using the FQ kit or the pump can be selected as an FQ model itself.
The great benefit of the FQ is that it can change the production and maintenance style of the customers without compromising on the desired operating characteristics.
The FQ kit provides high flexibility and functionality with easy maintenance and part replacement possibilities.
Moreover, to enable a varied range of process fluids and flow rates, the seal flange can accommodate different pump sizes!
For example, the DX 20 can be converted to DX 20/10 or 20/5 and FX 22 can be converted to FX 22/14 or FX 22/8.
In this way, the drive configuration and seal flange can be retained and there can be a possibility to have variations in flow rate depending on the size of the pump that will be installed.
The FQ pump is currently available for the following sizes:
Since the FQ version is unique, the feature is patent protected by MAAG.
Another innovative and smart extension of our industrial pump portfolio!
