Introduction:
Horizontal split case pump is a type of centrifugal pump that has two single suction impellers or a double suction supported between bearings. The pump casing is split axially with opposing suction and discharge flanges. This allows for easy maintenance on the pump.
Split case pump are typically used to carry low-viscosity liquids such as clear water and unsaturated wastewater from industrial processes at average heads. it can be applied for higher flow rate conditions that are not suitable for end suction pumps, such as fire pumps, portable water distribution, plant make-up water, pipelines, cooling water, and other industrial process flows with fairly thin fluids.
Specifications:
Pump diameter: DN150-800mm.
Capacity Q: 160 to 3750 m3/h.
Head: 10 to 125 Meters.
Working Pressure: 0 to 2.5 MPa.
Working Temperature: 0 to 135℃.
Applications:
- Commercial air conditioning
- Commercial heating
- Commercial hot water recirculation
- Commercial water pressure boosting
- District cooling
- District heating
- Drinking water treatment
- Irrigation
- Industrial cooling
- Desalination
- Industrial heating
