Filtration pumps made of stainless steel (1.4435)

We are a manufacturer of hygienic filtration pumps for various applications in the food, pharmaceutical and chemical industry. Development in SAWA and our own production of filtration pumps made of solid stainless steel 1.4435 / 316 L is carried out at our company headquarters in Degersheim SG. Self-priming and normal-priming SAWA filtration pumps of the HD, LE,LES, ZALR, ZA series are excellently suited for various applications.

Filtration pumps for the following fluids

Edible oils such as sunflower oil, rapeseed oil, olive oil, pumpkin seed oil, chili oil, thistle oil, coconut oil, frying oils, etc.
Drinking water, milk, beer, white wine, red wine, spirits such as fruit brandies, brandies, whisky
Fruit juice, apple juice, orange juice, distillates, pure alcohol

Applications of the filtration pumps

Liquid separation of solids,
Conveyance of soft and hard solids up to d 25 mm, depending on size of type LE
Gentle delivery of small and soft solids with the HD pump
Unloading of truck tankers with the LES series, no break in the flow of air when changing from one tank chamber to another

Pump types of our filtration pumps

Filtration pump type HD: The side channel pump with a delivery rate of up to 70 m3/h and a delivery head of up to 43m is quiet, self-priming, suitable for left-hand and right-hand rotation and therefore also suitable as a filter cleaning pump.

Filtration pump type LE: The 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 yet quiet pumping of liquid media and is widely used in filtration.

Filtration pump type LES: The hybrid centrifugal pump with up to 100 m3/h delivery rate. The ideal pump for tank truck loading and unloading and simultaneous filtration. Also ideal for any subsequent cleaning as a CIP return flow pump.

Filtration pump type ZA / ZAL: The spiral impeller pump with delivery heads of over 100 m. The ZAL series is used for low flow rates and at the same time high delivery pressures which are often required in filtration. In the compact single-stage design, pressures of over 10 bar are achieved. The pump is simple in design, effective in cleaning and energy efficient.
