Applications/Examples of results
At the San Luis Rey Water Reclamation Facility in Oceanside, California, there were issues with the pumps supplying sodium hypochlorite in the chlorine treatment cycle. By replacing the diaphragm pump with a Qdos (Qdos) peristaltic tube pump, the frequency of maintenance was reduced, and operators were no longer exposed to chemicals. Additionally, the operating pressure exceeded 0.5 MPa, which was beyond the pump's pressure specifications. The new Qdos CWT can be safely used at this high pressure. The innovative design of the Qdos pump, utilizing tube pump technology, ensures consistent long-lasting performance at high pressures of up to 0.7 MPa and is not affected by the exhaust or related vapor blockages from chemicals like sodium hypochlorite, which can cause some types of pumps to stop. Even when maintenance is needed, the pump head can be replaced quickly, easily, and safely without the need for tools.
