PUMPS IDEAL FOR HIGH-TEMPERATURE HEAT TRANSFER LIQUIDS
KSB’s HPK-L family of pumps for high-temperature heat transfer liquids combine high performance with energy efficiency and low maintenance costs. These versatile performers are designed for industrial processes or large-scale heating plant applications. HPK-L pumps are a complement to the company’s successful Etanorm heat transfer pumps, but are rated for higher discharge pressures (40 bar, or 580 psi, versus 16 bar for the Etanorms).This means that they can handle temperatures up to 240°C with water, or 350°C with thermal oil. With discharge nozzle diameters ranging from 25 mm to 250 mm, the HPK-L series can deliver flow rates as high as 1,600 m3/hr (7,000 gpm) and heads up to 222 metres.
These pumps feature medium-lubricated ceramic plain bearings and standardized mechanical seals. A heat barrier separates the hot operating area from the air-cooled seal chamber, preventing the heat-sensitive components from being exposed to the high temperatures. As a result, HPK-L pumps will operate reliably at high temperatures without any need for cooling water, significantly reducing installation and operating costs. The special back pullout design allows the casing to remain in the pipeline when the pump is dismantled for overhauls, making these pumps relatively easy and inexpensive to service. Like other KSB products, HPK-L pumps feature carefully optimized hydraulics to ensure high energy efficiency. With their combination of high performance, reliability and low total cost of ownership, KSB’s HPK-L series pumps can meet the most demanding requirement for high-pressure industrial process and heat transport applications.
