BISON, China’s leading water pump manufacturer, has launched a 1.5-in. hi-pressure water pump that water pump dealers can sell to building contractors, landscapers or agricultural enterprises.


The 1.5-in. water pump provides a displacement of 35m³/h and is ideal for a variety of applications:

  • Agriculture: Ideal for irrigation, pesticide spraying and water delivery in farm fields and greenhouses.
  • Construction: Essential for drainage of construction sites, supplying water to remote areas, and cleaning equipment.
  • Firefighting: Providing the continuous flow of water needed to extinguish fires, especially in rural or remote areas.
  • Industrial cleaning: Use high-pressure water to clean surfaces, ideal for removing dirt, mold, and grease from buildings, vehicles, and equipment.
  • Residential use: suitable for garden irrigation, and pool filling.

Advantages of hi-pressure water pump

  • Increased efficiency: hi-pressure water pumps provide a stronger water flow, significantly increasing water delivery rates, and allowing your customers to complete tasks faster.
  • Versatility: Compared to standard water pumps, the high-pressure output is suitable for multiple industries.
  • Powerful cleaning: Remove stubborn dirt, mold and grease more effectively through the concentrated power of water flow.
  • Wide coverage: 55m lift and 6m suction transport water to higher and further distances, suitable for applications that require water supply over long distances or elevated areas.
