Horizontal, single-stage volute casing pumps with design features and nominal rating to DIN EN ISO 2858 and enlarged sizes. The process design permits dismantling of the complete bearing unit towards the drive end, without the pump casing having to be disconnected from the piping. If a spacer coupling is used it is also unnecessary to disconnect the motor.
Series DBS volute casing pumps can be used where the requirement is for pumping dirty liquids or liquids with solids like for sewage plants (storm water, pre-filtered sewage, industrial effluents), chemical plants (chemical effluents, brines and lies, milk of lime, crystal sludge, filter material, plastic suspensions), rolling mills (scale-contaminated water from steel and copper rolling mills), foundries and iron and steel works (effluents and sludge from dust and arrester plants), construction industry (mixtures of water and cement and water from excavation ditches), paper and cellulose paper industry (chemical pulp and mechanical pulp, suspensions up to 6% absolutely dry), sugar mills (carbonation juice, concentrated juice, milk of lime) and food industry (thick mash, fruit and potato slices).
