New efficient high-pressure pump for a powerful performance
In June 2016 KSB Aktiengesellschaft, Germany, is launching its
Movitec 125 pumps, complementing its current range of vertical highpressure pumps. The multistage centrifugal pumps are designed for
fluids such as water, coolants, condensate and mineral oils. They are
ideal for industrial recirculation and fire-fighting systems, cooling
water circuits and washing plants as well as for boosting pressure in
general process applications, for example.
The engineers behind the new pump sets put special emphasis on
achieving outstanding hydraulic efficiencies. The efficiency of a pump
with a full impeller diameter is greater than 80 percent. The type
series handles flow rates of up to 192 cubic metres per hour (at
60 Hz) at heads of up to 125 metres. The permissible fluid
temperature ranges from -20 °C to +120 ˚C. As standard, the new
pump sets are driven by 2-pole IE3 motors of 15 to 45 kW.
Fitted with product-lubricated plain bearings made of tungsten
carbide, cast bases, and torsion-resistant pressure shrouds sealed
by confined O-rings, the pumps are highly robust and reliable.
Corrosion-resistant hydraulic components made of stainless steel
further add to these qualities.
Several material variants and flange connection options provide
users with maximum flexibility when it comes to installing and
operating the new pump sets. With easy-to-replace standardised
cartridge mechanical seals to EN 12756, the new Movitec 125 pumps
are easy to service and built to last.
As an option, the pump can be operated on a frequency inverter and
combined with high-efficiency motors to increase the system’s
efficiency and match the flow rate to actual demand.
