Technical Advantage

Powerful self-priming, no pre-filling

Adopts optimized internal self-priming loop structure, no need to pour water before startup. It features high self-priming height and fast priming speed, easy to operate and suitable for frequent start-stop working conditions.

Non-clog design for sewage

Equipped with large flow channel non-clogging impeller, it can smoothly transport sewage mixed with solid particles, fiber impurities and sludge. Not easy to be entangled or blocked, ensuring long-term stable conveying.

Robust cast iron pump body

The pump body is integrally cast with high-strength cast iron, featuring high pressure resistance, deformation resistance and good corrosion resistance. It can work continuously under full load for a long service life.

Alloy seal, leak-proof & wear-resistant

Fitted with high-quality alloy mechanical seal, high temperature resistance and wear resistance. It effectively prevents liquid leakage, adapts to complex sewage media and reduces frequent maintenance.

Compact, easy install & maintain

Compact integrated structure saves installation space, no special foundation required. Simple overall design makes daily inspection, disassembly and parts replacement much more convenient.
