Choose by Water Type
QDX-SC and WQD-SD serve different water conditions. Start with the liquid, rather than the housing alone.
STAINLESS-STEEL HOUSINGS
Metal Submersible Pumps
Compare QDX-SC and WQD-SD models with 304 stainless-steel housings. Choose by water condition, required performance and installation.

Before You Choose
Before You Choose
Use these points to compare the water, installation and operating requirements before choosing a model.
Start with the water type, then check all wetted materials, performance, controls, dimensions and electrical version alongside the stainless steel housing.
Check All Wetted Materials
A stainless steel housing does not establish compatibility for the seals, impeller or other parts in contact with the water.
Compare the Complete Pump
Check performance, controls, dimensions and electrical version alongside the housing material.
Explore the Applications
Compare these models for clean-water transfer or dirty-water drainage where a stainless steel housing is part of the product requirement.
Key Applications
Where these families may fit within their published limits.
Application suitability depends on the liquid, solids, required duty point, installation/control method and exact product configuration.
Common Questions
Questions to Check Before You Choose
Does a stainless steel housing make the pump seawater-safe?
No. Seawater suitability depends on all wetted materials, seals, salinity and operating conditions. Ask for a compatibility review before choosing either model for seawater.
Can I request private-label versions?
Yes. Share the selected model, market, quantity and changes you need. Electrical, branding, packaging and compatible construction changes are reviewed for the project.
