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: No coupling damage through well placed leakage hole. Safety reserve in dry running. Low maintenance operation. DIN standard.
