Download PDFA complete home waterworks system ready for immediate installation with a self-priming pump Wilo Jet HWJ 204-EM-50/2-2. The waterworks system includes a membrane pressure tank with a capacity of 50 litres, which absorbs pressure surges caused by the pump starting and reduces the number of pump activations. This protects the pump from wear and extends its lifespan. The stainless steel construction allows for outdoor use and prevents corrosion during prolonged inactivity of the pump. The pump is protected against dry running.

Note: To maintain quality, the product is tested by the manufacturer during production. It may contain residues of the test liquid.
