Hygienic Pumps

SAWA hygienic pumps made of stainless steel (1.4435), the first choice for your cleanest production results. With an efficiency of up to 75%, our hygienic pumps are successfully used in a wide range of industries and meet the EHEDG guidelines of the pharmaceutical and food industries.

The bolted and very thick-walled housing constructions promise a very high degree of robustness and process reliability. SAWA hygienic pumps are equipped with IEC standard motors. The stub shaft is simply pushed onto the motor shaft, is easy to position and very simple to fasten. Thanks to the balanced stub shaft and the flow-optimised impeller/housing geometry, optimum concentricity is guaranteed and noise is reduced to a minimum.

Pump types of our hygienic pumps

Hygienic pump type HD: The hygienic self-priming side channel pump with a delivery rate of up to 70 m3/h and a delivery head of up to 43 m is quiet, achieves a suction head of over 7 m and is suitable for both left-hand and right-hand rotation.

Hygienic pump type LE: The hygienic centrifugal pump with a delivery rate of up to 240 m3/h The perfectly matched, flow-optimised impeller and volute casing geometry achieves a very efficient and quiet pumping of liquid media. This pump is 100% clean due to the cleaning process and is also free of dead space.

Hygienic pump type LES: The hygienic hybrid centrifugal pump with up to 100 m3/h delivery rate. The ideal pump for pumping liquids with high gas contents. The ideal pump for tank truck loading and unloading as well as for CIP return flow applications.

Hygienic pump type ZA / ZAL: The hygienic centrifugal pump with delivery heads of over 100 m. The ZAL series can be used for low flow rates and simultaneously high delivery pressures and is therefore a very good alternative to multistage centrifugal pumps in the single-stage design. The hygienic pump is compact, simple in design, effective in cleaning and energy efficient.

Hygienic pump type MP: The hygienic peripheral impeller pump with a delivery rate of 100 - 7,000 l/h and delivery heads of up to 100m. The peripheral impeller pumps are used wherever small flow rates pulsation-free against high pressures are required under hygienic conditions. The symmetrical design is suitable for clockwise and anti-clockwise rotation.

Hygienic pump type BB + BA: The circular and rotary lobe pump with a delivery rate of up to 99 m3/h and delivery pressures of up to 20 bar, with 13 model sizes. This series becomes microbiologically clean by the CIP process. Surface qualities of up to Ra ≤ 0.8µm and corresponding certificates such as 3A or FDA are available and suitable for hygienic applications in the food industry.

Hygienic pump type C: The circular and rotary lobe pump with a delivery rate of up to 144 m3/h and delivery pressures of up to 20 bar, with 9 model sizes. This series has a frontal arrangement of the mechanical seal (integrated in the rotor) and is easy to maintain. With the EHEDG certificate, surface finishes down to Ra ≤ 0.5µm, this sterilizable version is suitable for the highest hygienic requirements of the pharmaceutical industry.
