ISW Series Horizontal Centrifugal Pump

ISW horizontal centrifugal pump is designed based on the structural combination of IS centrifugal pump and ISG vertical pump, and is an energy-saving product designed and manufactured in strict accordance with ISO2858 and JB/T53058-93 standard for pipeline centrifugal pumps. At the same time, hot water pumps, high temperature pumps, chemical pumps, oil pumps, etc. are derived from ISW according to different operating temperatures and media.

4. ISWB type horizontal oil pump, used for conveying gasoline, diesel, kerosene and other petroleum products, use temperature T: -20℃-120℃.

  • Working conditions

1. Suction pressure ≤1.0Mpa, or pump system working pressure ≤1.6Mpa, that is, pump suction pressure + pump head ≤  1.6Mpa, pump static pressure test pressure is 2.5Mpa, please indicate the system working pressure when ordering. When the pump system working pressure is greater than 1.6Mpa, it should be separately proposed when ordering. So that the flow-through parts and connecting parts of the pump can be made of cast steel during manufacturing.

2. Ambient temperature <40℃, relative humidity <95%.

3. The volume content of solid particles in the conveyed medium does not exceed 0.1% of the unit volume, and the particle size is <0.2mm.

Note: If the medium used is fine particles, please indicate it when ordering so that wear-resistant mechanical seals can be used.
