Gear Pumps KF 730 ... 1500 KRACHT 1 End cover 2 Plain bearing bushes 3 Gear 4 Housing 5 Flange cover 6 Shaft seal 7 Shaft end Working Notes Gear pumps KF are used for pumping a wide variety of fluids. Gear pumps KF are distinguished especially by their wide range of variants which are assembled as required on the modular principle and also permit subsequent upgrade. The standard housing sections are of grey cast iron. The gear units are manufactured from high-strength case-hardening steel, hardened and mounted in special multi-compound plain bearing bushes. The standard drive shaft is...

KF 730 ... 1500 noise optimized for medias with increased air percentage The noise optimized pumps in the KF series are designed for conveying for medias with increased air content, predominantly for use as lubricating oil pumps in gears. Special measures prevent the otherwise normally increased noise present in auriferous gear oil. The noise levels do not exceed or only barely exceed the measurements with non-auriferous oils. Also, there is no noise spectrum shift to higher, unpleasant frequencies. In applications without auriferous portions in the media, it is not recommended to use this...

Gear Pumps KF 730 ... 1500 KRACHT Type Key (Ordering example) (1) Measures for noise optimisation are only possible for one rotational direction and only effective for aerated oils or vacuum (only in connection with seal versions that are suitable for vacuum operation). Can lead to a reduction of delivery rate. KRACHT GmbH • Gewerbestr. 20 • 58791 Werdohl, Germany • Phone +49 23 92.935-0 • Fax +49 23 92.935 209 • Email info@kracht.eu • Web www.kracht.eu
