Hydraulic designs suitable for solids-laden liquids common in wastewater and industrial services.
Service-Friendly Access
Clean-out and maintenance features support faster inspection and reduced downtime.
Application
Flexibility
Rugged construction and configuration flexibility to match demanding operating conditions.
S-Series & XS-Series Self-Priming Pumps
Wastewater | Municipal | Industrial | Dewatering
Heavy-duty self-priming pumps designed for demanding solids-handling service.
- Rugged construction for demanding solids-handling applications
- Maintenance-oriented design features for faster service
- Wide range of sizes and configurations (model dependent)
When We’d Recommend It:
A strong choice when the water source or system arrangement calls for a vertical configuration, particularly for wells, intakes, open sources, boosting, or high-capacity water movement.
Resources
I-Series High-Head Self-Priming Pumps
Industrial | Municipal | Higher-Head Applications
Efficiency-forward designs often selected for higher-head / higher-pressure duties.
- Efficiency-forward hydraulic designs (application dependent)
- Service-friendly construction aligned with field maintenance needs
- Often selected for higher-head / higher-pressure duties confirm with published curves
When We’d Recommend It:
Consider the I-Series when the application requires self-priming and solids-handling capability at higher head or pressure than typical wastewater transfer duties.

What Determines the Right All-Prime Pump?
Selecting a fire pump starts with the requirements of the fire protection system. The appropriate configuration and equipment can depend on:
Flow & Head Requirements
Required capacity and total dynamic head establish the hydraulic performance the pump needs to deliver.
Solids & Fluid Conditions
Solids size and concentration, liquid properties, temperature and chemical compatibility influence pump and material selection.
System & Installation Requirements
Suction lift, available NPSH, piping, installation constraints and existing equipment all affect the final configuration.
Flowstar can review these requirements alongside All-Prime Pump capabilities to help identify the appropriate equipment for the application.
All-Prime Pump Interchangeability for Retrofit & Replacement Projects
A major advantage in retrofit and replacement projects where minimizing rework is critical.
All-Prime pumps and replacement components are designed for full dimensional and parts interchangeability with
Gorman-Rupp® T, Super T and U Series platforms.
- Helps reduce retrofit time and disruption
- Supports standardization and simplified long-term maintenance
- Ideal for replacement projects where piping and mounting changes are undesirable

Answers to Common All-Prime Pump Questions and Performance Issues
Priming issues are often caused by air leaks on the suction side, insufficient liquid in the priming chamber, or blockages in the suction line. Even self-priming pumps require initial priming.
Troubleshooting Tips:
- Inspect all suction line fittings and hoses for air leaks using soapy water
- Ensure the pump casing is fully filled with liquid before startup
- Clear debris from suction strainers, impellers, and check valves
- Verify suction lift is below 25 feet (the practical limit)
- Confirm the suction flapper check valve is functioning properly
- Keep discharge valves open during priming to allow air evacuation
Proper installation ensures optimal performance and easy maintenance access.
Installation Guidelines:
- Maintain at least 18 inches of clearance in front of the back cover plate
- Install pumps above the liquid level for self-priming applications
- Keep suction inlet height below 5 meters (16 feet)
- Ensure level mounting — use shims to eliminate vibration
- Use independent pipe supports to prevent stress on the pump body
- Align pump shaft and motor output coaxially
- Install suction strainers with drainage area 2–3× the suction pipe cross-section
Proper sizing requires understanding your system’s hydraulic and environmental conditions.
Key Factors to Consider:
- Required flow rate and total dynamic head (TDH)
- Solids content and maximum particle size (up to 3-inch spherical solids)
- Suction lift height and available NPSH
- Liquid temperature (max 160°F / 71°C for standard models)
- Chemical compatibility — choose from cast iron, stainless steel, CD4, Hastelloy-C276
- Viscosity and specific gravity of the fluid
Tip: Contact Flowstar with your full application details for expert pump selection and sizing support.
A structured maintenance plan extends pump life and prevents breakdowns.
Daily:
- Check for leaks at mating surfaces and connections
- Listen for unusual noises or vibration
- Monitor bearing and motor temperature
- Verify liquid levels in the priming chamber
Monthly:
- Compare suction/discharge pressures to baseline
- Inspect mechanical seals for wear or leakage
- Check impeller clearance using the external adjustment system
- Tighten bolts and verify coupling alignment
Annually:
- Replace seals, impellers, and wear plates via the suction cover
- Inspect and replace rotating assemblies if worn
- Adjust impeller-to-wear plate clearance
Yes. All-Prime pumps are designed for full interchangeability with several leading brands of solids-handling self-priming pumps.
Benefits:
- Direct replacement without modifying piping
- Simplified inventory using industry-standard dimensions
- Rotating assemblies removable without disturbing piping
- Standard NEMA motor compatibility
- 150# ANSI flange connections for universal fit
This makes All-Prime ideal for upgrading existing installations while maintaining infrastructure.
