The WQ Series Submersible Sewage Pumps are specialized for sewage transfer, designed to handle sludge, industrial wastewater, and municipal domestic wastewater containing solids (e.g., small gravel) and fibers (e.g., textile scraps). With a non-clogging design and anti-winding feature, these submersible pumps eliminate common issues like impeller blockages, ensuring continuous operation in wastewater treatment plants, construction sites, and municipal sewage systems. Their compact submersible structure saves installation space, while easy maintenance reduces downtime—making them a cost-effective choice for low-to-medium head sewage handling.
| Capacity | 10-5000 m3 /h |
| Head | 7-60m |
| Power | 0.35-315kw |
| Sizes | 50-600mm |
| Speed | 740-2950r/min |
The pump’s impeller and flow channel are optimized to prevent fiber entanglement and solid particle blockage, efficiently handling media with up to 30mm diameter solids. Ideal for sludge transfer and food processing wastewater.
As fully submersible units, the pumps can be installed directly in sewage tanks or pits, eliminating the need for complex above-ground pump rooms. This saves space and reduces pipeline layout costs, suitable for both temporary and permanent wastewater treatment projects.
With a 10-5000 m³/h flow rate and 7-60 m head, the series covers diverse needs—from small-scale residential sewage lifting (0.35kw models) to large municipal wastewater plants (315kw models). Multiple pump sizes (50-600mm) ensure compatibility with different pipeline systems.
The simplified structure allows quick access to internal components (e.g., mechanical seals) without disassembling inlet/outlet pipes. Corrosion-resistant materials (e.g., cast iron, stainless steel options) enhance longevity in acidic/alkaline wastewater.
Media Type: Sludge, industrial wastewater, municipal domestic wastewater (solids ≤30mm, fibers ≤50mm);
Installation: Fully submersible (IP68 protection class for motors);
Seal Type: Double mechanical seal (prevents sewage leakage into motors).
SPMC prioritizes the WQ Series’ durability for harsh sewage environments:
All pumps undergo 100% factory performance testing (including load and leakage tests) before delivery;
Motor windings use moisture-resistant insulation materials to withstand long-term submersion;
Feedback-driven design improvements—based on 5000+ customer cases, optimizing impeller anti-clogging performance;
Consistent quality control aligning with municipal wastewater equipment standards.
Yes—optional stainless steel (304/316) materials are available for pumps used in acidic/alkaline industrial wastewater handling (e.g., printing and dyeing wastewater).
Most models support up to 5m submersion; customized deep-water models (up to 10m) are available for large sewage pits.
Under normal municipal sewage conditions, routine maintenance (seal inspection, impeller cleaning) is only needed every 6-12 months—far less frequent than non-submersible sewage pumps.
