New high-pressure pump unites efficiency with flexibility
KSB Group has launched the first size of its newly developed MultiTec Plus type series – size 150.
These pumps have been specially developed for transporting drinking water, with optimum hydraulic efficiency being the focus. Combined with extremely economical synchronous reluctance motors and variable speed systems of the PumpDrive type series, the pump sets have a very low energy consumption and a very small carbon footprint.
The variable speed systems automatically match pump output to actual demand, making sure that no energy is wasted. Optionally, the KSB Guard monitoring system can monitor the pumps’ condition by measuring the temperature and vibration data and sending it to the KSB Cloud in real time. If any deviations or irregularities compared to normal operation occur, the system will also send messages to efficiently plan maintenance measures and minimise downtimes.
MultiTec Plus pumps are designed for a casing pressure of 25 bar. They can reach a maximum head of almost 250m and a flow rate of up to 470m³/h.
They are exclusively driven by four-pole three-phase motors. Compared with higher-speed pump sets with smaller nominal diameters, the new pumps, running at 1450 (50 Hz) or 1750 (60 Hz) rpm, will reach the same maximum flow rate, yet run much more quietly. Their low rotational speeds help reduce wear, which has a positive impact on both the service life and the efficiency of the pump set.
Energy efficiency, long service life and low noise emissions are especially important in the water sector.
The maximum temperature of the fluid handled should not exceed 60°C. The transition areas of the diffusers are protected against wear by casing wear rings. As the arrangement of suction and discharge nozzles can be matched to customer requirements, the pumps are particularly versatile and flexible to install.
The pump sets are available in different designs, such as versions for horizontal and vertical installation with different bearing arrangements. Robust in design and equipped with flow-optimised hydraulic systems as well as easily replaceable wear parts, MultiTec Plus offers a high degree of operating reliability at low energy and maintenance costs. Self-adjusting plain bearings made of silicon carbide and innovative axial thrust balancing ensure high operating reliability.
