Flowserve QLC and QLQC Vertical Double Case Twin Volute Double Suction Pump for high flow API applicationsQLC and QLQC Vertical Double Case, Double Suction Twin Volute

Brand: Worthington
Description:

The Flowserve QLC and QLQC are vertical double case, double suction, twin volute pumps engineered for high-volume, low-pulsation fluid transfer. These API 610-compliant pumps are ideal for critical services in water injection, pipeline transport, cooling water circulation and refining operations. The vertical configuration minimizes footprint while the double suction design ensures hydraulic balance and quiet operation.

The QLC and QLQC are double casing, double suction, vertical turbine pumps. Available in single or multistage units and featuring true twin volutes, these pumps incorporate the proven hydraulics of the QL and QLQ into a double casing configuration.

QLC and QLQC Double Suction Twin Volute Applications

Desalination, Dewatering and Water Supply (mining), Fire Protection, Water Supply and Distribution (water), Condensate Extraction, Leaching Acid, Auxiliary Services (power), Descaling, Geothermal Well Services, Molten Salt Transfer, Ground Water Development and Irrigation

  • Industries:
    General Industries, Mining, Water Resources, Power Generation, Primary Metals, Oil and Gas

Versatile Seal Chamber accommodates installation of cartridge-style single, dual pressurized and dual unpressurized mechanical seals to meet safety and environmental requirements.

Keyed Impeller design provides ease of maintenance.

Renewable Impeller Wear Rings enable the restoration of original clearances and promote high operating efficiency.  Casing wear rings are standard.

Line Shaft Bearings are spaced to ensure the first critical speed of the rotor is well above running speed.  Sleeves are provided under bearings for additional shaft protection.
