1. Aplication
The KSB Megachem centrifugal pump is recommended for
handling chemical products, aggressive organic and
inorganic liquids, oil, water, condensate and other liquids
mainly used in the following applications:
-Chemical and petrochemical;
- Sugar and alcohol industry;
- Boiler feed;
- Aux. circuits in refineries;
- Aux. circuits in the industry (paper, food, synthetic fibers,
others);
- Water supply;
- Irrigation;
- Air conditioning;
- Fire-fighting;
- Drainage;
- Circulation of heat transfer oil.
2. Design
Horizontal, single- stage end suction and top centerline
discharge. The "back-pull-out" design allows maintenance
and repair services through the back side, without dismantling
piping supports.
Dimensionally built to ISO 2858 / DIN 24256 and
mechanically to ANSI B 73.1.
