vertical cooling water pump
LC vertical cooling water pump are "engineered to order" large flow vertical pumps for industrial pumping needs and sump design, with semi-open or closed cast impellers available in sizes starting from 650 mm (26") impeller diameter and nq 75 (Ns 3'870). They are mainly designed as cooling water pumps for thermal power and combined-cycle power applications but can also be used in water or other industries.
High pump efficiency
Modern fabricated suction bell and bowl casing incorporating swirl break for stable pump performance curve
Semi-open or closed cast impeller design for best fit and optimum efficiency
Segmented elbow to optimize pump efficiency
Optional full pull-out construction to reduce lifting crane capacity and ease maintenance
LC vertical cooling water pump is specifically designed as circulating water pump for the following fields:
Cooling water pump in utility thermal, nuclear, gas-fired combined-cycle power plants and industrial power stations
Water supply
Irrigation
Flood control and drainage
General water service
Cooling water pump for refining and seawater intake pump for open rack vaporizers in LNG regasification terminals
