2.11 Self-priming centrifugal pumps 2.12 Rotary lobe pumps The GEA Tuchenhagen self-priming pump of the TPS series are used for conveying aggressive, clean liquids that are free of abrasive constituents. Pumps of the TPS series are horizontal, self-priming pumps. They stand out by their sturdy construction and high operational reliability and are preferably used in the food processing and luxury food industry as a CIP return pump. Fig. 3 - Self-priming centrifugal pump, type TPS GEA Tuchenhagen rotary lobe pumps of the VPSH and VPSU series are used whenever viscous, sensitive or solids-containing liquids must be gently transferred. Type VPSH is used in hygienic applications of all kinds. Type VPSU has been designed especially for high aseptic requirements that are standard in sterile areas. The special design of the Skimitar rotors and the pump’s design enable the pump to convey a wide range of media: from low-viscous media to products with a viscosity of up to 1,000,000 mPas or even media with suspended solids. Due to the shape of the Skimitar rotors, a particularly high efficiency is achieved. Fig. 4 - Rotary lobe pump VPSH 11 GEA Tuchenhagen
