Advantages of SP series self-priming sewage pump

1. Strong self suction performance - SP non-clogging self-priming sewage pump has a self suction height of basically 7-8 meters, while ordinary self suction sewage pumps can only suction within 5 meters.

2. Strong sewage performance - SP self-priming sewage pump adopts a semi open impeller that can pass through large particle impurities, while ordinary self suction sewage pumps generally use a closed impeller that can pass through relatively small particle diameters.

3. Low maintenance cost - SP non clogging sewage pump adopts a replaceable wear-resistant disc design, and later maintenance only requires replacing the wear-resistant disc without damaging the pump body. Ordinary self suction sewage pump body wear must be replaced with a new pump body, which is costly.

4. Adjustable impeller clearance - SP self-priming sewage pump adopts radial sealing, and the position of the bearing body can be adjusted within a certain range, which can control the gap between the impeller and the wear-resistant disc, ensuring the self suction performance of the pump. If ordinary self suction pumps wear, the clearance between the mouth ring will increase, affecting the self suction performance and pump efficiency.

5. Durable for idle operation - SP self-priming pump adopts an oil lubricated sealing structure, which can idle for a short time without damaging the mechanical seal. Ordinary self-priming sewage pumps cannot idle and will burn out the mechanical seal in just a few seconds

6. The same caliber flow rate is larger - the flow rate of SP self suction sewage pumps with the same caliber can exceed that of ordinary self suction sewage pumps by more than 50%, making them widely used in the field of emergency drainage.

7. Convenient Cleaning - The full-size cleaning port design can quickly and conveniently remove garbage even in the event of blockage without the need to disassemble the pump body. The closed impeller of a regular self suction sewage pump is relatively easy to clog, and once garbage entangles the impeller, the pump body needs to be removed to clean, which is very inconvenient in practical applications.
