Non-clogging Pump DBS 3216...30040 TECHNICAL DATA Output: up to 1200 m3/h Delivery head: up to 100 m Speed: up to 3600 rpm depending of the pump size and material execution Medium temperature: max. 110 °C Casing pressure: 10 bar Shaft sealing: stuffing box or mechanical seal Flange connections: PN 10 Sense of rotation: clockwise, when seen from the drive on the pump APPLICATION Series DBS volute-casing pumps can be used where the requirement is for pumping dirty liquids or liquids with solids. 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 Effluents and sludges from dust and and steel works: arrester plants Construction industry: Mixtures of water and cement and water from excavation ditches Paper and cellulose Paper, chemical pulp and mechanical pulp industry: suspensions up to 6% absolutely dry Sugar mills: Carbonation juice, concentrated juice, milk of lime Food industry: Thick mash, fruit and potato slices (parings) DESIGN Process type, single-stage, volute casing pumps with design features and nominal rating to ISO2858/EN22858 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. CONSTRUCTION Casing pressure: Max. 10 bar between -10 º C and +120 ºC Please note: Casing pressure = Inlet pressure + shut off head. Max. test pressure 16 bar Branch positions: Suction branch axial, discharge branch radial upwards. Flanges: Connection dimensions of flanges DIN 2501 PN 10 . Flanges can be supplied drilled to ANSI Optional the pump can be supplied with a flange adapter piece on the suction side (see sectional drawing, pos. 72.20) Bearings: Execution B: Pump end: one cylindrical roller bearing to DIN 5412 Drive end: one deep groove ball bearing to DIN 625 The bearings are grease lubricated Execution C: Pump end: one cylindrical roller bearing to DIN 5412 Drive end: one deep groove ball bearing to DIN 625 The bearings are oil lubricated Execution S: Pump end: one cylindrical roller bearing to DIN 5412 Drive end: two angular contact ball bearings in Oarrangement. The bearings are grease lubricated Execution T: Pump end: one cylindrical roller bearing to DIN 5412 Drive end: two angular contact ball bearings in Oarrangement. The bearings are oil lubricated Shapes of impellers: Double channel impeller (code Z) or triple channel impeller (code D) Free-flow impeller (code F) If required, the sealing clearance gap on the suction side of pumps fitted with double and triple channel and wear plates can be arranged for flushing.
