The ZUS gear pumps are designed for handling viscous and dense liquids with lubricating characteristics, not containing any solid particles (as sand, ash, crystals etc.) up to a temperature of 100 °C and pressure differences up to 0,5MPa. They are used to advantage for pumping a wide range of viscous liquids and fluids in chemical, petrochemical and other industries, such as oils, tar with phenolated water, water-glass, varnishes, soap, glues, grease,etc. They are used to advantage due to their low speeds for handling in food and sugar installations to pump sugar products, molasses and sirobs.
