BISON is a world-renowned wholesale water pump manufacturer that provides cast aluminum high pressure pumps, which combines cast aluminum’s durability with the water delivery efficiency of high-pressure technology. It is a good choice for water pump trader who wants to optimize their supply chain.

Advantages of cast aluminum high-pressure pump:

  • Easy to operate: Cast aluminum has high strength and high pressure resistance, ensuring the durability of the water pump. Compared with traditional water pumps, cast aluminum pumps are significantly lighter in weight for easier handling, installation and start-up.
  • Corrosion resistance: Cast aluminum has excellent rust and corrosion resistance and can be used in salt water or harsh chemical environments. Extends the water pump’s service life and avoids after-sales problems.
  • High performance: The high-pressure pump can provide a flow rate of 42m³/h and strong momentum. It is suitable for pressure cleaning, car washing, agricultural spraying, dust control and other applications. It can also quickly complete water delivery over longer distances.
  • Improve efficiency: The good thermal conductivity of cast aluminum enables efficient heat dissipation and prevents the water pump from overheating and shutting down. Through high-voltage technology, ensure continuous and smooth operation and reduce the cost of use for your customers.
