MODEL-H CONVEYOR
Model-H Conveyor for Heavy-Duty Sludge Applications
Designed to convey abrasive, high-moisture sludge in wastewater treatment and dewatering environments where uptime and durability matter.
Built for the Toughest Applications
The Model-H Conveyor is purpose-built to handle sludge and other demanding materials that challenge conventional conveyor systems.
With its robust design and patented continuous path™ system, the Model-H eliminates multiple transfer points—reducing downtime, cutting maintenance costs, and improving overall performance.
Handles sludge, grit, and semi-solid materials with ease.
Designed for reliability in high-demand, nonstop environments.
Minimized spillage, fewer motors, and reduced maintenance needs.
Why It Perfoms Better Than Flat Belt Conveyors
| Feature | Model-H | Flat Belt Conveyor |
|---|---|---|
| Incline Capability | Up to 45° | Up to 20° |
| Path Flexibility | 3D turns & curves | Mostly straight or limited |
| Transfer Points | None | 2 or more |
| Motors Required | 1 low HP motor (2–10 hp) | Multiple motors |
| Maintenance | Focused on stations | Spread across entire system |
| Belt Alignment | Positive chain guidance | Tension-based, frequent |

Model-H vs Flat Belt
Model-H
| Incline Angle | 45° |
| Radius | 9–24 feet |
| Energy Efficiency | Single low horsepower motor (2–10 hp) |
| Drive Type | Chain driven conveyor |
| Cleaning System | Scraper system for dewatered sludge |
| Turning Capability | Horizontal and helical turns |
| Path Type | Three-dimensional path |
| Applications | Municipal and industrial use — sludge, grit, screenings, bulk materials |
| Ease of Use | Simple to use and assemble |
| Belt Width Options | 20″, 26″, or 32″ |
| Cost Efficiency | Low capital cost for belt replacement |
Flat Belt
| Cost Competitiveness | Competitive |
| Maintenance | Requires increased maintenance to lubricate idler rollers along the conveyor |
| Routing & Containment | Routing restrictions and poor containment |
| Path Capability | Requires two or more conveyors to convey an offset path |
| Energy Consumption | Uses more energy due to multiple motors |
| Incline Capability | Straight line and slight inclines up to 20° between transfer points |
| Belt Replacement Cost | High capital cost for one belt replacement |
| Drive System | Belt-driven system requiring frequent attention and alignment |
Model-H – Sludge Conveyor
The Model-H sludge conveyor is the heaviest duty Serpentix designed to convey sludge up to 400 tons per hour at maximum speeds on slightly more than 100 feet per minute over distances up to 400 feet. Belt widths for Model H are 20″, 26″, and 32″.
Positive guidance and tracking for the belt are provided by roller carriages attached to and pulled through a channel track by a steel link chain. The belt is attached to and supported by the carriages and intermediate belt chain attachments. The chain is driven by a sprocket located at the drive station, and tension is set by a screw adjusted spring in the tension station.
The sludge Conveyor – Serpentix Model-H Conveyor is built to haul larger capacities of sludge over longer distances. The Serpentix Model-H implements the usage of rollers to permit longer hauls at a lower horsepower.
The Model-H like the Pathwinder, still gives clients the ability to make turns in three dimensions, and work around complex job-sites. The Model-H also uses the same belting system as the Pathwinder for easy repair and less maintenance.
Proven in the Field
Over the years Serpentix has designed and fabricated the Model-H Conveyor. This conveyor design launched the company. For thirty years each component has been scrutinized and every opportunity has been taken to improve performance.
- Convey up to 100 tons/hour
- Elevate a material up to 45° inclines
- Turn a 9-foot radius
- Conveyor lengths up to 300-feet
- Belt widths of 20″, 26″ or 32″
- Transport of materials types from solids to near-liquid
Applications
