The self-priming pump type HD impresses with its excellent priming capability (up to 7 m) and an excellent conveying behavior with liquids containing gas. Because of its robust design the maintenance costs are very low and the lifetime is long. The design of the pump guarantees a gentle and silent pumping of different liquids. The sanitary design and the material 1.4435 makes the pump easy to clean. That's why the pump is often used in the beverage, food and pharmaceutical industries.

| L |
Because of its specially designed impeller, the SAWA centrifugal pump ZAL is capable to reach delivery heads up to 10 bar with a single stage. This characteristic is often used for cleaning applications with spray balls. An advantage of the single stage pump against a multi stage pump is the better drainability which is of importance in many applications in the pharmaceutical industry. The SAWA centrifugal pump typ ZA is designed for higher flow rates and is also made of stainless steel 1.4435. The pump is predestined to be used in sanitary and sterile applications.
Hybrid centrifugal pump LES

| Nominal pressure: | max. PN 63 |
| Surface roughness: | down to Ra < 0.4 μm |
| ATEX for zonen: | 1 and 2 |
| Heatable: | no |
| Magnetic coupling: | yes |
| L |
The SAWA hybrid centrifugal pump LES has a better suction capabilty compared to a normal centrifugal pump. Through its special designed recirculation system in the pump cover the pump can be an alternative to a self-priming pump. Especially for CIP-retrun applications or for the unloading of tank trucks, a SAWA hybrid centrifugal pump is an interesting solution.
Submersible centrifugal pump LET
| L | |
|---|---|

| Heatable: | no |
| Magnetic coupling: | no |
| L |
The SAWA submersible centrifugal pump with motor in dry well installation is available for a submersion depths up to 3 m. It is manufactured out of corrosion resistent stainless steel. The pumps are made according to the customers's requirements and are ideal for application with solvents, industrial waste water, alcohol and chemicals. A bearing free version is available for submersion depths up to 0.6 m. This guarantees a long lifetime e.g. with abrasive liquids.
Peripheral pump P/MP
| L | |
|---|---|
| Flow rate: | up to 7 m3/h |

| Nominal pressure: | max. PN 63 |
| Surface roughness: | down to Ra < 0.4 μm |
| ATEX for zonen: | 1 and 2 |
| Heatable: | no |
| Magnetic coupling: | yes |
| L |
The SAWA peripheral pump is mostly used with magnetic coupling. Despite of its compact design the peripheral pump can reach delivery heads up to 10 bar. Because of its linear performance curve it is adjustable easily with a frequency converter. The magnetic coupling guarantees a hermetically sealed execution which is of high importance with hazardous liquids or in ATEX zones. It is possible to run the peripheral pumps in both directions.
