Water Pump, Self Priming Sewage Pump

Product Description

The Self-Priming Sewage Pump by SUHUA is a vertical, self-priming, outer-recirculation pump designed for sewage, wastewater and mixed liquid transfer. It supports flows from 5 to 800 m³/h, heads of 10 to 80 m, and can self-prime up to 4.5–5.5 m. With materials suited for pH 6–9 (or stainless versions pH 2–13), and operation up to 80 °C, it provides reliable, efficient service for municipal and industrial drainage systems.

🌍 Applications

This self-priming sewage pump is ideal for fluid transfer where submersion or priming is difficult. It finds wide use in:

  • Municipal sewage discharge systems and stormwater drainage
  • Industrial wastewater and effluent handling
  • Agriculture / aquaculture drainage and irrigation return
  • Paper, textile, chemical, food factories for mixed suspensions
  • Power plants / factories handling plant drainage or cooling water return

In many settings, its self-priming and non-clogging features reduce installation complexity and prevent downtime in sewage or mixed liquid pipelines.

💡 Features & Benefits

This pump is engineered to deliver durability, performance, and operational simplicity.

  • Self-Priming & Non-Clog Design — integrates axial reflux and outer recirculation to handle solids and prevent clogging
  • Wide Range & Flexible Use — works across a broad flow / head span making it useful in various municipal and industrial systems
  • Material Flexibility — standard cast iron for common sewage; stainless steel available for corrosive media
  • Energy Efficient — optimized hydraulics reduce losses and operating costs
  • Easy Operation & Maintenance — modular design allows quick access and servicing
  • Robust for Sewage Conditions — capable of handling slurries and mixed solids in drainage systems
  • OEM / Factory Direct Supply — advantage in cost, customization, and export support

Many buyers choose this pump because its self-priming and anti-clogging feature minimizes downtime and reduces need for additional foot valves or priming equipment.

❓ Frequently Asked Questions

Q1: What kind of sewage or wastewater can it handle?

This pump is suitable for sewage, industrial effluent, mixed liquids with suspended solids, fibers, or slurries (within reason).

Q2: How does its self-priming capability work?

Thanks to its outer recirculation and design, it can prime itself up to 4.5–5.5 meters, eliminating the need for foot valves or manual priming.

Q3: What materials are available and what pH ranges can it support?

Standard models use cast iron for pH 6–9; stainless-steel versions can be used for aggressive media in pH range 2–13.

Q4: What is the maximum liquid temperature it can manage?

The pump is rated for operation up to 80 °C.

Q5: Can this pump be customized to my project’s flow and head?

Yes — as a manufacturer, SUHUA supports customization of flow, head, material, impeller type, and connection size.
