Features/Product Advantages

The Wilo-TWS series stainless steel submersible deep-well pumps feature a compact design, excellent performance, high efficiency and energy savings, a small footprint, and light weight; they operate smoothly and are easy to install. The pumps are equipped with an internal elastic spherical check valve to prevent damage caused by backflow or pipeline water hammer upon shutdown. They can be installed either vertically or horizontally.

Construction

Multi-stage submersible pumps (4", 6", and 8") feature NEMA-standard connections, axial impellers, and an integrated check valve design. All components are made from corrosion-resistant materials.
