KSB, the world’s most experienced supplier of pumps and pump parts, announced its KRT submersible pump line now features IE2-compliant high-efficiency motors up to 10HP in four and six poles that provide an extremely reliable and versatile dry and wet pump solution — with low energy loss.

Increased energy savings
KSB’s IE2-compliant high-efficiency motors give its submersible KRT pumps improved efficiency, reducing ene

rgy losses through several enhancements:

• The design reduces heat losses in stator windings and
  rotor squirrel cage.
• Increased number of laminations by up to 25 percent per KW, plus optimized stator rating and voltage, reduces magnetic reversal losses in the stator cores.
• High-quality components reduce friction losses in bearings and mechanical seals.
• Heat exchange by convection reduces losses that would be imposed by recirculation of coolant liquid, maintaining lower motor temperatures and extending the useful life of the pump.

In addition, KSB’s high-efficiency motors comply with NEMA MG1 part 31 requirements for variable speed operation, enabling installations in wet installations with low-liquid levels in which the pump must continue running constantly. Dry-pit submersible installations, either vertical or horizontal, are also possible.

Flexibility and longer wear life
The ability to use the KRT pumps in both wet and dry installations gives the product great flexibility to be used in different applications.

When configured as a submersible pump, the KRT can easily transition to a dry operation without interruption when water levels drop. This ability to run continuously as water levels change reduces wear caused by frequent stops and starts and extends the overall pump wear life. When configured as a dry pit pump, the KRT can continue running seamlessly even if flooding occurs.

In addition, the KRT employs KSB’s highly optimized hydraulic systems, and operators can select from a variety of impeller styles, ensuring the right impeller is used for each application. Free passages from 3 inches and up reduce clogging and maintenance. And all parts are made of the highest quality materials. Cast iron is the standard material for the KRT pumps when handling wastewater, but special materials are available for industrial applications.

Operators can be assured of the safety of this pump — it is completely sealed. No water can enter the motor, even in the case of a damaged cable. Motor temperature is continually monitored by sensors that prevent overheating, and all pumps are fitted with a moisture sensor in the motor casing that will signal if water ingress to the motor occurs.

Fully backed by KSB experience
At KSB, more than 100 years of hydraulic pump design experience, combined with a focus on continuous improvement, create pumps that are exceptionally reliable and functional.

Operators and maintenance engineers working in wastewater applications will save time and effort with KSB’s efficient, highly reliable KRT pump while experiencing lower energy losses over the life of the pump’s operation.
