Do you want to increase your water pump sales? BISON is a global manufacturer of water pumps, and its new high pressure cast iron pump combines high pressure performance with cast iron construction. The 2-inch inlet and outlet sizes are compatible with various hoses and pipes.

WP20HI high pressure cast iron pump uses BS170F gasoline engine. The 210cc one-cylinder, air-cooled, 4-stroke gasoline fuel engine is designed for efficiency and performance. Direct injection and OHV specifications enable low fuel consumption while maintaining stable output, and meet the stringent requirements of different customer demands, such as irrigated farms, construction sites or firefighting emergencies where water needs to be delivered quickly.

Advantages of WP20HI pump:

  • Easily water uphill: With a maximum lift of 75 meters, tasks such as irrigating fields on slopes or transporting water to a storage tank at a higher location can be easily accomplished.
  • Long-distance transportation: The 36 cubic meters/hour displacement ensures a strong flow rate, ensuring that your customers can effectively transport large amounts of water over long distances.
  • Durable: Unlike plastic alternatives, cast iron is known for its high strength and corrosion resistance. Cast iron pumps are built to withstand harsh environments and frequent use, minimizing downtime and replacement costs.
  • Enhanced heat dissipation: Cast iron’s superior thermal conductivity effectively transfers heat away from the pump’s core, preventing overheating and ensuring smooth operation.
