MultiFree-Pump with vortex impeller

Product catalog summary
Application: MultiStream and MultiFree pumps are designed for handling effluent or sewage in municipal and industrial settings, as well as surface water drainage. They are portable and suitable for emergencies. UAK models handle sewage water, while UFK models are explosion-proof for hazardous locations.
Specifications: MultiStream pumps feature an adjustable axial gap for efficiency, a vertical, single-stage design with a single-channel impeller, and a submersible motor with IP68 enclosure. Materials include GG grey cast iron and corrosion-protected shafts. MultiFree pumps have a vortex impeller and similar construction materials.
Technical Data: Both pump types use a common shaft for pump and motor, with deep groove and inclined ball bearings. They have silicon carbide mechanical seals and are safe to run dry. The motor is protected by winding thermostats and is tested by PTB for UFK types.
Installation: Pumps are installed vertically with a guide rail system or pump base, with flange coupling according to DIN standards. They come with a 10 m cable but without a plug or pump base.
Performance: Designed to handle effluent containing fibrous matter, solids, mixed water, raw effluent, raw sludge, and rainwater. They maintain a minimum flow rate of 0.7 m/s in the pressure pipe, adhering to ISO 9906 performance tolerances.
Operation: Pumps can operate continuously when submerged (S1) or intermittently when not submerged (S3), with specific operation cycles detailed for each model.
Specifications and Components: Detailed specifications for various sewage pump models, including codes and configurations. Highlights the need for specific control units, especially for models requiring direct start. Mentions the use of flushing tubes to reduce deposits and surface scums in sump designs.
Control Units: Categorized based on compatibility with single or duplex units, with or without explosion-proof features. Lists specific codes for each type of control unit.
Additional Features:
  • Seal Leak Detector: Monitors the sealing of the oil chamber in pumps, activating a buzzer if water ingress occurs.
  • Discharge Connection: The PN 6 / PN 10 discharge connection allows for universal compatibility with existing pipe systems, with specific dimensions and bolt sizes provided.
Operational Enhancements:
  • Adjustable Axial Gap: Ensures optimal efficiency by allowing adjustments to the gap between the impeller and wear ring, reducing blockage risks.
  • Ceramic Anti-Wear Coating: Protects channel type impellers from wear due to abrasive liquids, ensuring long-term durability.
  • Moisture Sealed Cable Inlet: Prevents water intake through power cables using a special resin, ensuring lasting moisture resistance.

MultiFree-Pump with vortex impeller-1

1 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. ð The sewage pumps UAK are suitable für handling sewage water. ð In hazardous locations explosion-proof sewage pumps UFK have to be used. The adjustable axial gap of the MultiStream-pump makes it possible 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: ð effluent which contains fibrous matter ð effluent which contains solids ð mixed water ð raw effluent ð raw sludge ð 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 mechanical seal. 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 protection II 2 G EEx d IIB T4. Materials Pump, motor case and impeller in GG grey cast iron (single channel 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 D 302–4.2E-0810 Sewage pumps MultiStream Adjustable single-channel impeller Connection alternatively PN 6 or PN 10 Safe to run dry Controllable oil chamber Plug type cable connection (UAK/UFK 10...–100...) SiC mechanical seal independent of sense of rotation Moisture sealed cable inlet Built-in motor protection Types of operation: Up to 40°C medium temperature UAK/UFK Motor submerged: continuous operation S1 UAK/UFK Motor not submerged intermittent operation S3 (e.g. 15% = 1,5 min operation and 8,5 min pause)
