Dewatering, sewer bypass, lift-station backup, industrial process, and emergency response. Sized correctly the first time. Quote turnaround within 24 hours.

The Godwin Dri-Prime and Heidra series have set the global benchmark for portable dewatering and sewer-bypass pumping for over 100 years.
Automatic priming up to 28 ft of suction lift. No foot valve, no operator priming, no babysitting.
Open-impeller design passes solids up to 5 in — handles raw sewage, sludges, and slurries without clogging.
Liquid-bath silicon-carbide mechanical seals dissipate heat through the pump casing. Pumps survive dry running indefinitely.
From compact CD80 trash pumps to 24-in CD500M skid units. Total dynamic head from 75 ft to 640 ft on standard models.
Diesel-driven units run overnight without refueling. PrimeGuard 2 intelligent controls enable unattended automatic operation.
Direct sourcing of new Godwin equipment with engineering-led pump selection — backed by a Houston-based team that understands Texas applications.
Complete Godwin US catalog coverage — Dri-Prime portable pumps, Heidra submersibles, the DBS Backup System, plus power, control, and accessory equipment.

High Volume · Medium Head · Large Solids
The workhorse of the Godwin range. 13 base models plus 3 elevated-head variants in 2-in to 24-in discharge. Sewer bypass, construction dewatering, municipal applications.

Medium Volume · High Head · Solids Handling
Single-stage impeller delivers up to 640 ft TDH — no staging required. High-rise dewatering, long discharge runs, jetting, pressure boost.

Stringy Material · Self-Cleaning Impeller
Featuring Flygt N-technology with self-cleaning impeller. Designed for fibrous, stringy material applications — wipes, rags, hair, fiber-laden wastewater.

Hydraulic Submersible · Deep Sumps
When suction lift exceeds 28 ft, Heidra takes over. Hydraulic submersibles powered by remote diesel or electric power packs. 17 models including high-head variants.

Compact Electric · Confined Spaces
Compact electric submersibles for vault drainage, manholes, and confined-space dewatering. Run-dry capable with silicon-carbide seals. 6 models from 0.5 HP to 2 HP.

Lift-Station Redundancy · Permanent Install
100% pump-station backup instead of backup power. Engaged on loss of primary power, switch-gear failure, or routine maintenance. PrimeGuard 2 with FST remote monitoring.

Construction Dewatering Systems
Centrifugal pump with high-volume vacuum pump and air/water separator. Self-jetting wellpoint header system. 3 models — CD100MV, CD150MV, CD225MV.

Positive Displacement · Sock Dewatering
Positive-displacement rotary lobe pumps in 6, 8, and 12-in models. Higher flow rates with lower horsepower. Wellpointing, sock dewatering, low-abrasion service.

Compact Engine-Driven · 4 Variants
Engine-driven wet-prime portable pumps. Four variants: Dewatering, Trash, Pressure, and Plastic. Construction, irrigation, agriculture, manhole drainage, jetting.

GHP Series · 20 kW – 325 kW
15 generator models for powering electric pumps and light towers. Skid- or trailer-mounted. Three-phase prime ratings from 23 kW to 327 kW.

GLT416 · 5–7 Acre Coverage
Trailer-mounted light tower with 4-pole brushless 6,000 W generator and four 1,000 W metal halide lamps. 30-ft mast, 60-hour run time, single-person deployment.

PrimeGuard 2 · FST · VFD
PrimeGuard 2 microprocessor controller, Field Smart Technology (FST) remote monitoring, and industrial-grade electric pump control panels including VFD up to 400 HP.

OEM · Mechanical Seal · Filter · Service
Three Godwin OEM kit types: Dri-Prime 1–2 Year Parts Kit, Diesel Engine Filter Kit (Tier 2/3/IT4/T4), and Mechanical Seal Kit with Viton/SS gaskets.

Suction · Discharge · HDPE · Plugs · Ramps
Complete hose lineup (suction, discharge layflat, composite OS&D, PVC layflat, helix, chemical, air), HDPE pipe 4–36 in, fusion machines, road ramps, and inflatable pipe plugs.

Quick Disconnect · Flanged · Threaded
Full Godwin Quick Disconnect coupling system. Flanged ends, screw ends, strainers, pipe bends (45°/60°/90°), tees, Y-adapters, reducers, increasers, sealing rings.
Godwin equipment covers virtually every portable pumping application across municipal, industrial, construction, and emergency-response markets.
Sewer bypass, lift-station backup (DBS), digester cleaning, sludge removal, force-main bypass during repair, emergency floodwater drainage.
Open-pit and underground drainage, process water supply, pit dewatering, tailings transfer, slurry handling.
Wastewater bypass, temporary fire pump duty, plant turnaround support, tank transfer, permanent process pumping.
Site drainage, stream diversions, foundation dewatering, drill rig water supply, well-point support.
Tank cleaning, hydraulic fracturing water supply, product transfer, pipeline pigging, refinery turnarounds.
Barge ballasting, jetting operations, dock and harbor dewatering, vessel transfer.
Every Godwin inquiry is sized using established hydraulic engineering methods — pump selection done right the first time.
System-curve construction, NPSH-available calculations, friction loss analysis using Hazen-Williams or Darcy-Weisbach, and pump-curve matching to specific duty points.
Sewer bypass design with peak-flow factoring, redundancy planning, lift-station capacity matching, and discharge piping sizing.
Certified pump curves, dimensional drawings, NPSH data, performance test reports — formatted for engineer review and project specs.
Diesel vs. electric trade-off analysis: emissions tier, fuel logistics, run-time requirements, noise constraints, motor sizing for VFD operation.
Wetted-parts metallurgy for application chemistry — cast iron, 316 SS, CD4MCu, hard iron, high chrome — for pH range, abrasive content, and chloride exposure.
PrimeGuard 2 configuration, level float setup, VFD selection for variable-speed operation, SCADA integration planning, soft-start vs. across-the-line motor starting.
