The hybrid pump LES from SAWA Pumpentechnik AG has an inducer as well as an integrated feedback system in the specially developed pump cover, which makes it possible to successfully use it as a self-priming pump.
The SAWA Pumpentechnik AG developed the LES hybrid pump, based on LE, which was launched two years ago, and LES for Leise Efficient Self-priming. The newly developed feedback system in the pump cover, in which, among other things, An inducer is used to increase the suction pressure, this pump is excellently suited for applications in which high gas components are to be conveyed or suction lines are to be completely emptied. Likewise, this pump is predestined for suction and snort operation without damaging the mechanical seal. Accordingly, the pump is e.g. Ideal for use as a CIP return pump or for tank emptying.
The essential advantages of the LES pump versus a side canal pump can be summarized as follows:
Ideal inserts for high flow rates at high pressure
First practice tests were already completed and we were able to convince customers of the advantages of the LES pump. The operating director of a large milk processing company expressed the following:
LES-hygiener-Einsatz-bei-Grossmolkerei
"The pump LES runs to our fullest satisfaction, very quietly and efficiently, especially efficiency is an important cost factor in 24 h operation, and the silent operation is a further advantage because the environment also needs to be taken into consideration , Is the ideal prerequisite for reducing the loss of the product and for the subsequent CIP cleaning. In addition, the truck drivers have great pleasure that the unloading of the vehicles is now even faster. "
The LES pump, like the entire LE series of pumps, is based on the EHEDG regulations, which ensure hygienic process operation as well as rapid cleaning. If a medium remediation of the pump body takes place, By means of the new, non-trapped SAWA residual emptying valve.
SAWA Pumpentechnik AG uses the high-quality, corrosion-resistant chrome-nickel molybdenum 316L stainless steel and 1.4435 for all pumps. The media-contacting components are electropolished and have a smooth, pore-free surface.
All SAWA pumps can be equipped with different mechanical seal systems, which of course must always be adapted to the medium to be conveyed. Various material pairings such as, for example, Carbon / chromium steel, hard metal / carbide metal, SiC / SiC or combinations of the mentioned slip rings and counter rings. Designs such as quench, tandem, back to back, static or pressure superimposed and special designs are a matter of course for SAWA. All elastomers of mechanical seals and secondary seals can be supplied with the required certificates for a wide range of materials (for example, FDA and USP Cl VI)
The philosophy of SAWA Pumpentechnik AG is characterized by cooperation, precise clarification of the needs (in many cases on-site), elaboration of problem solving, delivery of detailed offers, fault-free deliveries and short response times in the after sales service. This creates trusting partnerships with long-term relationships.
