Why Godwin Wellpoint
Construction dewatering with wellpoints requires simultaneous water and air handling — Godwin's three-pump-in-one design integrates everything in a single trailer.
Integrated Vacuum + Centrifugal
Single unit combines centrifugal water pump, belt-driven vacuum pump, and air/water separator. No separate vacuum truck or compressor needed.
Self-Jetting Wellpoint System
Compatible with Godwin's quick-disconnect wellpoint and header pipe system. Sets up faster than traditional flanged systems.
Up to 200 CFM Air Handling
Vacuum pump pulls air through wellpoint screens, lowering groundwater table around the excavation. Critical for sandy / silty soils.
Solids Up To 3⅛ in
Hardened wear parts and a dry-running liquid bath mechanical seal handle real construction-site conditions.
20° Joint Deflection
Header pipe joints adapt up to 20° to terrain without losing suction or pressure integrity. Faster setup on uneven ground.
Three Frame Sizes
CD100MV (4×4), CD150MV (6×6), and CD225MV (8×8) cover residential foundation work through major commercial / industrial excavation.
Wellpoint Models & Specifications
Electric drive specifications shown. Diesel drive available on request. CD225MV is skid-base only due to weight — trailer mounting available with custom configuration.

Wellpoint System Components
A complete wellpoint dewatering system requires more than the pump — we configure the full system per project:
Available Configurations
- Pump unit. CD100MV / CD150MV / CD225MV centrifugal + vacuum pump assembly with air/water separator.
- Wellpoint screens. Self-jetting wellpoint screen + 1½-in riser pipe (sized by depth of excavation). Multiple screens per project, spaced per soil hydraulic conductivity.
- Header pipe. Quick-disconnect header pipe with 20° joint deflection. Sized to handle peak flow from all wellpoints at minimum friction loss.
- Swing arms / connections. 90° wellpoint swing arm assemblies, lever closure rings, gate valves, hose shanks, clear suction hose.
- Dust plugs / accessories. MQD dust plugs with lever, riser adapters, O-rings, connection hardware.
- Drive type. Electric (230/460 V) standard for permanent / extended construction projects. Diesel available for remote / temporary jobs.
Wellpoint Applications
Wellpoint dewatering is the standard approach for excavation in saturated sandy / silty soils where surface pumping alone won't lower the water table.
Foundation Excavation
Building foundations in high water table areas — dewater the excavation perimeter to allow dry working conditions.
Utility Trenching
Sewer / water / gas line installation in saturated soils. Wellpoints lower the trench water table for safe pipe-laying.
Underground Tank Installation
Petroleum tanks, water tanks, lift stations — anywhere a tank must be set in saturated ground.
Slope Stabilization
Permanent or temporary slope dewatering to reduce pore water pressure and prevent slope failure.
Cofferdam Dewatering
Inside-cofferdam dewatering for bridge piers, marine construction, and waterfront foundation work.
Mining / Quarry Dewatering
Open-pit and underground mining where groundwater inflow exceeds surface pumping capacity.

Wellpoint FAQ
How many wellpoints do I need?
Wellpoint spacing is determined by soil hydraulic conductivity (permeability), excavation depth, target dewatering depth, and acceptable cone-of-depression geometry. Sandy soils typically need wellpoints every 3–6 ft along the excavation perimeter; silty soils may require closer spacing. Site geotechnical data drives the design — we'll work with your geotech to size the system.
What's the difference between Wellpoint and a regular dewatering pump?
Regular dewatering pumps remove standing water in an excavation — they can't lower the surrounding groundwater table. Wellpoint systems use vacuum to draw down the groundwater table around the excavation, keeping the inside dry through hydraulic isolation. The vacuum pump is the key difference — it pulls air through the wellpoint screens to maintain suction in the well system.
Can wellpoints handle deep excavations?
Single-stage wellpoints reach approximately 18–22 ft below the pump centerline. For deeper excavations, multi-stage wellpoint systems are used — the first stage dewaters down 15–20 ft, then a second-stage system installed at that lower elevation reaches another 15–20 ft. Excavations over 30 ft typically use deep-well systems instead of wellpoints.
Electric or diesel drive?
Electric for projects over 2 weeks duration, urban sites with grid power, or where noise/emissions matter. Diesel for short-duration jobs, remote sites, or emergency response. Electric drive also enables VFD operation for energy-efficient flow matching as wellpoint demand changes.
Do you sell the full wellpoint accessory kit?
Yes — quick-disconnect wellpoint screens, riser pipe (by the foot), header pipe in 6/10/20-ft sections, swing arms, gate valves, hose shanks, MQD dust plugs, sealing rings, and connecting hardware. We configure complete systems based on excavation length and depth.
