General data CI, CIU Applications The CI and CIU pumps are primarily designed for industrial applications: Typical applications CI CIU Water treatment! " Industrial washing and dish-washing machines! " Pressure boosting of process water! eating and cooling in industrial processes! " Air-conditioning! " Airwashing, moisturization, humidification!! (softened water) Water supply and pressure boosting!! (potable water, also slightly chlorinated) Fertilizer/dosing systems! " Aquafarming! In addition, the CI, CIU pump is suitable for many specialized applications.! Recommended " Applicable Pumped liquids Thin, clean, non-aggressive and non-explosive liquids without solid particles or fibres. The pumps are able to pump liquids such as demineralised water, softened water, cleaning solutions, light oils and other light chemicals. When pumping liquids with a density and/or viscosity higher than that of water, motors with correspondingly higher outputs must be used, if required. Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are chloride content, p value, temperature and content of solvents, oils, etc. Operating conditions Liquid temperature: 15 C to +11 C Maximum ambient temperature: + C Maximum operating pressure: 1 bar Maximum inlet pressure is limited by maximum operating pressure. Maximum operating pressure and liquid temperature The actual operating range depends on the operating pressure, the pump type, the type of shaft seal, the pumped liquid and the liquid temperature. Shaft seal The shaft seal is to be selected on the basis of liquid temperature and type of liquid. For other liquids than water, the chemical resistance of the materials - incl. seal face, seat and rubber components of the shaft seal - must be taken into account. The following table shows available shaft seal types.

Technical data CI, CIU Curve conditions The guidelines below apply to the curves shown on the previous pages: 1. Tolerances to ISO 996, Annex A, if indicated.. Measurements were made with airless water at a temperature of C. 3. The curves apply to a kinematic viscosity of υ = 1 mm /s (1 cst).. The bold curves indicate the recommended performance range. The thin curves are only a guide. 5. Due to the risk of overheating, the pumps should not be used at a flow below the minimum flow rate. The curve below shows the minimum flow rate as a percentage of the nominal flow rate in relation to the liquid temperature. Qmin [%] 5 15 1 5 5 6 7 8 9 1 11 1 t [ C] TM1 9158 153 1
