WQK8-22QG Sewage Pump Company – Why Choose a Manufacturer That Tests

There are a lot of companies selling sewage pumps. Some just rebrand generic imports and hope for the best. Others — like us at HAQUANPUMP — actually manufacture and test the pumps we sell. The WQK8-22QG is a good example of why that matters.
What Testing Reveals
Every WQK8-22QG we produce goes through a run test before shipping. We check flow rate, head pressure, power consumption, and cutting performance. If the numbers don’t match the spec sheet, the pump doesn’t ship.
Here’s what the spec says for this model:
| Parameter | Value |
|---|---|
| Model | WQK8-22QG |
| Outlet | 25 mm |
| Flow | 8 m³/h |
| Head | 22 m |
| Power | 1.1 kW |
| Speed | 2900 rpm |
The Difference You Can’t See
Inside the pump, we use C&U bearings — a reputable Chinese brand. The mechanical seal is graphite versus silicon carbide, which handles dirty water better than cheaper combinations. The cutting blades are hardened alloy, not soft stainless that dulls after a few weeks.
Why It Matters to You
When you buy from a company that manufactures and tests, you get consistent quality. The pump you receive will perform the same as the one in the catalog. That’s not always true with unbranded imports.
Applications Summary:
manufacturer direct, tested pumps, quality assurance, industrial sewage, reliable pumping
