All-Prime Pumps
Built to beat clogging, priming delays, and costly repairs.
In industries where uptime is non-negotiable — mining, wastewater treatment, food processing, and manufacturing — pump failures caused by clogging, unreliable priming, and inaccessible maintenance lead to costly shutdowns and operational inefficiencies.
Flowstar is your Canadian resource for All-Prime Pumps, offering self-priming, solids-handling pump systems that solve these exact challenges. Facilities across Newfoundland and Labrador, New Brunswick, and Nova Scotia are reporting improved performance, reduced maintenance costs, and greater reliability with All-Prime’s engineered solutions.

Clogs Shouldn't be a Daily Maintenance Task
XS-Series: Designed to Handle Real-World Solids Without Constant Intervention
Whether you’re dealing with sludge, pulp, sediment, or food waste, the All-Prime XS-Series pumps are engineered to keep your fluids moving:
Features include:
- Handles up to 3-inch diameter solids without clogging
- Semi-open impellers with pump-out vanes reduce buildup
- Quick-access clean-out covers let you clear blockages fast — no piping disconnection required
These anti-clogging features can benefit wastewater systems in the the industrial and municipal sectors .
All-Prime XS Series Pump
Priming Shouldn’t Be a Guessing Game
The S-Series: Reliable Self-Priming That Works — Even After Shutdowns
If your current pump needs a vacuum system or foot valve just to start, you’re wasting time and risking failure. The All-Prime S-Series simplifies startup:
- Self-primes up to 25 feet suction lift
- No foot valves required
- Volute retains liquid for dry suction re-priming
- Suction flapper check valve speeds priming and improves reliability
This means no confined space entry, fewer restart delays, and less troubleshooting.

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

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.
