Plastic impeller solar pumps and stainless steel impeller solar pumps are multi-stage centrifugal pumps for deep well. The multistage centrifugal pump increases the water pressure by the rotation of the impeller to achieve The rise of water.
The biggest difference between a plastic impeller solar pump and a stainless steel impeller solar pump is the difference in impeller material. The impeller of the stainless steel impeller solar pump is made of 304 stainless steel. Compared to plastic impellers, stainless steel impellers are less prone to wear, more durable and have a longer service life. Moreover, the plastic impeller solar pump outlet is made of copper, and the stainless steel solar pump outlet is made of stainless steel.
In short, the stainless steel impeller solar pump is made of higher quality materials, with better quality and longer service life, so the price is higher.
