Rodelta LSM

Features:

• Vertical design drinking water pump can be easily installed. (Prefabricated pump chamber option.)
• Closed Impeller with diffuser casing, single or Multi stage
• Diffuser/impeller combination reduces radial loads; Easier to match to customer system; Optimizes efficiency
• Robust construction due to low pump rotor load, minimum shaft deflection, smooth running, high availability, reduced stock of spares
• Low noise emissions
• High hydraulic efficiency
• Hydraulic performance to DIN 24255
• Space saving construction (building cost / footprint)
• Possibility of hydraulic tuning *(NL) if operating point has changed over the years
• Construction of LSM design provides cost savings in building costs. (Linked example is worked out using LS as an example, however, the same parameters apply for LSM implementation.)
• No alignment required when installing the pump thereby reducing installation costs

Specifications:

• Delivery size up to 250mm
• Capacity up to 3500m3/hr
• Head up to 220m per stage
• Suitable for liquid Temperature: Up to 80ºC
• Sealing Arrangement: Gland packing or with mechanical seals
• Flanges Drilling Standard: Flanges can be as per BS EN/DIN/ANSI/ASA standard

Applications:

• Drinking Water
• Cooling Water
• Process Water
• Clean & lightly contaminated liquids

Applications:

• (Drinking)Water Pumping stations
• Data Center
• On board ships (confined spaces)
• Chemical & Petrochemical plants
• Booster pumping stations

Constructional features:

• Closed couple pump construction with impeller directly mounted on extended motorshaft.
• Low pump rotor load
  – Radially due to the diffuser design
  – Axially due to replaceable wear rings on the impeller and pump casing as well as balancing holes in the impeller
• Minimum shaft deflection
  – Stiff pump shaft, with grease lubricated ball bearings designed for minimum life time of 20000 hours
• Smooth running
  – The pump is supported by a stable foot
  – The sturdy shaft runs in well dimensioned bearings and the long throttling tracts between the wear rings also stabilized  the running of the rotor
• High availability
  – Due to the long running life of the pump components
• Reduced stock of spares
  – Due to the modular pump design
• seal dimensions to DIN 24960
• Nozzle positioning in steps of 45°
• Bearings grease lubricated
• Top pull out for LS
• Renewable wear rings
• Compact build / Space saving design
