| Application MultiStream pumps are suitable for handling effluent or sewage in municipal and industrial pumping stations as well as in surface water drainage applications. The smaller typs are also used very successfully as portable units to deal with emergency situations. ͕ The sewage pumps UAK are suitable fr handling sewage water. In hazardous locations explosion-proof sewage pumps UFK have to be used. The adjustable axial gap of the MultiStream-pump makes it pos앭sible to re-optimize the efficiency in case of abrasion by adjusting only one single screw. This can be done very cost-effective when the maintenance is carried out and the pump keeps its optimum performance on a long-term basis. MultiStream-pumps are recommendet for: effluent which contains fibrous matter Օ effluent which contains solids mixed water Օ raw effluent raw sludge Օ rainwater Technical data Pump Vertical, single-stage, submersible, pump case with horizontal discharge, single channel impeller and short shaft extension. This provides a longer service life for the ball bearings and the mechaͭnical seal. | ||||||
| Types of operation: Up to 40°C medium temperature UAK/UFK Motor submerged: continuous operation SI UAK/UFK Motor not submerged intermittent operation S3 (e.g. 15% = 1,5 min operation and 8,5 min pause) | ||||||
| Bearings Common shaft for pump and motor, deep groove and inclined ball bearings, grease-packed. Seal Silicon carbide mechanical seal independent of sense of rotation, oil chamber and artificial carbon mechanical seal or rather SiC mechanical seal (or duplex rotary shaft seal up to size 35) as secondary seal, safe to run dry. Motor Submersible, enclosure IP68, activation through special purpose plug or control unit, protected by winding thermostats, UFK types tested by PTB (German tech. inspection authority), type of proͭtection () II 2 G EEx d MB T4. Materials Pump, motor case and impeller in GG grey cast iron (single chanínel impeller with n = 2800 min-1 from size 55/2 in spheroidal graphite iron GGG), corrosion protected shaft (no contact with pumped liquid), flexible rubber sheathed cable. Installation Install pump vertically with guide rail system or pump base. Flange coupling according to DIN, coupling size B or hose tail bend up to 3" possible. Scope of supply Pump acc. to EN 12050 with 10 m cable without plug, without pump base: a) as sewage pump UAK b) as explosion-proof sewage pump UFK | ||||||
