Features

1. Utilize a robust stainless steel 304 pump tube with a thickness of 1.5mm, complemented by a stainless steel 304 diffuser and a durable stainless steel 304/316 pump head. This combination ensures high strength, aesthetic appeal, and long-lasting durability.

2. The innovative design of the multi-stage floating impeller significantly lowers the starting torque requirements and prevents blockages caused by small sand particles. This sand-resistant capability extends the motor's service life, offering enhanced performance and reliability.
