K 系列螺杆泵技术参数K 系列螺杆泵多种安装方式

The new generation Series K has been thoroughly reengineered. As the most sold universal pump series K offers a number of benefits.The pump prevents the accumulation of residue forming fluids by locating the leakage hole before the ball bearing. Secondly, KRAL offers the advanced quality of SiC mechanical seals, which contains graphite, as a solid lubricant to reduce the coefficient of friction in dry running conditions. The O rings with high fluorine content are suitable for higher temperatures and are chemically stable. The Series K offers innovative seal concepts. A proven selection of radial rotary shaft seals, mechanical seals and a hermetically sealed magnetic coupling are available as standard. A robust and compact design rounds off the profile.Your advantages:

• Nocoupling damage through well placed leakage hole.
