Combining centrifugal force with integrated mixing capabilities, this pump ensures homogeneous blending while maintaining full sanitary standards. Whether you are processing dairy products, beverages, pharmaceuticals, or fine chemicals, the LES 190 delivers consistent quality, gentle product handling, and easy cleaning. Its robust construction and modular design make it a reliable workhorse for continuous production lines.
The LES 190 model stands out in the SAWA series for its high flow capacity (up to 190 m³/h) and hygienic design compliant with global food and pharmaceutical regulations. It is engineered to transfer and mix fluids simultaneously, eliminating the need for separate mixing tanks in many processes. This saves floor space, reduces energy consumption, and shortens production cycles. Below, we detail the key features, technical specifications, and benefits that make this pump an excellent investment for your facility.
Key Features and Benefits
Integrated Mixing Function: The specially designed impeller and casing create a vortex that blends ingredients during transfer, ensuring uniform consistency without additional equipment.
Hygienic Construction: All wetted parts are made of stainless steel (AISI 304/316L) with surface finish Ra ≤ 0.8 μm. No dead zones, full drainability, and CIP (Clean-in-Place) capable.
High Efficiency: Optimized hydraulic design reduces energy consumption by up to 15% compared to conventional centrifugal pumps, lowering operational costs.
Gentle Product Handling: Low shear impeller minimizes damage to shear-sensitive products such as yogurt, cream, or protein solutions.
Flexible Installation: Horizontal or vertical mounting options, with a wide range of motor power (0.75 kW – 11 kW) and electrical configurations (IP55, IE3, etc.).
Easy Maintenance: Back pull-out design allows quick access to the impeller and seals without disturbing piping connections.
