Reduce downtime with our range of both suction and discharge pipe spools
Slurry pump spools connect pumps to surrounding process pipework and are often exposed to the harshest operating conditions in the circuit. High pressure slurry, vibration, pulsation, alignment stress and abrasive wear can quickly destroy conventional rigid spool systems.
Many sites still rely on steel spools, couplings and expansion joints, however these arrangements often create unnecessary leak paths, difficult installation and uneven wear issues. Raised sphere expansion joints can cause significant flow impacts and typically don’t use very abrasion resistant compounds
A smarter solution is to replace rigid spool sections with Abrasor mining hose assemblies.
By strategically using flexible hose spools on suction and discharge lines, sites can improve reliability, reduce downtime and protect both pumps and connected pipework.
Common Problems with Rigid Suction Spools
Pump suction connections are highly sensitive to misalignment, vacuum conditions and installation accuracy. Rigid steel spools often create unnecessary stress at the pump inlet.
Common failures include:
- Misalignment creating stress and metal fatigue
- Vibration transfer into pump and pipework
- Steel liner detaching under wear and vacuum
- Difficult fit-up causing delays during shutdowns
- Premature failure due to wear
The Abrasor® Solution
Abrasor mining hose is ideal for suction spools because it combines flexibility, vacuum resistance and simplified installation.
Key Benefits
- Absorbs movement vibration and alignment variation
- Can be easily made to varying diameters, optimising flow and reducing wear points
- Reduces stress on pump suction nozzles
- Fewer joints reduce potential for leaks and uneven wear
- Faster installation than rigid multi-piece spool systems
- Cost effective
Why Discharge Spools Fail
Discharge lines face high pressure slurry, severe vibration and abrasion directly from the pump. Conventional rigid steel spools often fail due to concentrated wear and vibration loading.
Common issues include:
- Rapid wear on bends and reducers
- Excess pressure on surrounding equipment due to vibration
- Leaking flanges and connection points coming loose
- Multiple spool sections increasing leak paths and uneven wear
- Frequent shutdowns for replacement & maintenance
The Abrasor® Solution
Abrasor mining hose is highly effective on discharge lines because it combines wear resistance and vibration absorption.
For aggressive duties, our Abrasatech liner delivers exceptional abrasion resistance while flexible construction protects surrounding equipment.
Key Benefits
- Handles vibration and misalignment
- Longer wear life in abrasive slurry service
- Can replace bends, spools and expansion joints in one assembly
- Reduced leaks and maintenance downtime
- Protects pumps and downstream piping systems
