Product Description

📌 Basic Info & Overview

The high-performance Self-priming non-clogging sewage pump is a cutting-edge solution integrating self-priming and sewage handling capabilities. It eliminates the need for bottom valves or manual water priming, efficiently handling soil, sediment, and solids up to 60% diameter of the outlet. This system significantly reduces labor intensity and is designed for urban emergency rescue, engineering sewage, and industrial fluid transfer.

❓ Frequently Asked Questions

How long does it take to start pumping water on-site?

The standard configuration includes a built-in vacuum assist system, allowing the pump to be unloaded and operational in 3 minutes or less. It can reach a 7-meter self-priming height in 120 seconds.

What size solid particles can the pump handle?

The non-clogging impeller handles solids up to 50-60 mm, such as branches and gravel. An 8 mm stainless steel filter provides secondary interception.

Can the pump be used on narrow urban roads?

Yes, the unit is mounted on a short-axle trailer with a turning radius of ≤ 6 meters and a width of 2.3 meters, making it suitable for narrow streets.

What maintenance is required after long-term storage?

Simply check engine oil/antifreeze, open the fuel valve, and use the "One-touch Start." Maintenance costs are low, typically involving once-a-year filter replacements.

Is the material resistant to corrosive sewage?

Yes, we use high chromium alloy or stainless steel options with epoxy ceramic coatings to ensure durability against wear and corrosion.

Can the system operate continuously for long durations?

Absolutely. The unit is designed for continuous operating times of ≥72 hours with a large-capacity fuel tank (≥300 L) and high-performance cooling systems.
