Water pump L series

handself-primingrotary lobe

The individual customer solution The Premiumlobe offers the ideal conditions for use in sophisticated processes. Due to a conclusive concept for hygienic and non-hygienic applications it is a synthesis of highest technical know-how and practical feasibility. The contactless running of the pump elements in rotary lobe pumps opens up important perspectives: On one hand it is perfect for hygienic applications due to the complete elimination of abrasion and product contamination; on the other hand the pump elements are wear-free with clean liquids. An innovative design of the gearbox and the shaft configuration is part of our mission in order to improve significantly the performance of the PREMIUMLOBE compared to other pumps, mainly conventionally designed: Shafts with an extremely short shaft overhang and large diameters for maximum stiffness; preferably large bearings with high capacity in order to increase service life and reliability and to allow high pressures; selection of material with preferably low coefficient for thermal expansion in order to reduce temperature shock sensibility. Surfaces and materials 1.4404 standard (equal AISI 316L) for wetted metallic material 1.4435, 1.4539 and 1.4462 optionally (lowest delta-ferrit contents). Raw material always high quality rolled steel. No use of cast iron parts due to danger of porosity Special "cold" welding procedures are standard. Electro polishing and any surface harshness up to Ra<0,4 µm are available.
