Reich Single Submersible pump 18L Durable high-performance immersion pumps and their advantages: The special high-tech seal with fat deposits makes REICH pumps especially durable and suitable for short dry runs. A patented ventilation system which is integrated into many of our pumps provides immediate output after immersing into the tank. REICH pumps are extremely quiet and almost not audible. The surface of the casing is dirt resistant, easy to clean and therefore extremely hygienic. A check valve which is integrated into many REICH pumps reduces the assembly efforts. Higher output than pressure pumps. 100% inspection before leaving production.
