APPLICATION GUIDE
Drainage & Water Removal
Choose by the water, solids and required flow. Compare models for removing standing water and transferring water through your installation.
Selection
What to Check Before Choosing
01
Water and Debris
Describe the water and the type and size of particles.
02
Draining Time
Estimate the volume and how quickly it needs to be removed.
03
Lift and Hose
Share the vertical lift, hose length and internal diameter.
04
Available Space
Check access, intake clearance and room for level controls.
05
Final Water Level
Decide whether you need bulk drainage or shallow-water cleanup.

Common Questions
Questions to Check Before You Choose
Should I choose a clean-water or dirty-water pump?
Start with the debris in the water. Clean-water models have smaller particle limits; dirty-water models allow soft particles within their stated limits. Neither label alone confirms suitability for sand or fibrous waste.
How do I estimate the drainage time?
Divide the water volume by the flow available in your installation. Use the pump curve at your working head, rather than maximum flow. Allow for changing water level and hose conditions.
