Beavers customers include:
Suction and discharge spools connect your slurry pumps to the rest of your circuit, and they see the worst conditions in your plant. High‑velocity, turbulent slurry, pressure fluctuations and tight reducer geometry make them some of the most failure‑prone pieces of pipework. Standard steel spools can’t cope – they wear out quickly, misalign when pumps vibrate and are hard to install. Beaver’s custom pump spools and reducers, built using Slurryflex® mining hose and ceramic‑lined reducers, deliver longer wear life and reliable performance.
Whether you need suction spools to match a new pump layout or discharge reducers that handle abrasive slurry and vibration, our engineered solutions keep your pumps running and your plant online.
Common Pump Spool Issues
Abrasion & Wear
Slurry pump spools are exposed to erosive, impact and leading edge wear. Turbulent slurry can wear through rubber lined steel spools, causing liners to debond. Impact wear occurs when high velocity slurry strikes the bend of a reducer, creating localised hotspots. Leading edge wear happens when the internal diameter of adjoining spools doesn’t match, so the slurry catches on the lip and wears through the joint. These wear mechanisms lead to leaks and unplanned repairs.
Vibration & Noise
Pumps generate noise and vibration, and rigid spools amplify this. Rubber lined steel cannot absorb vibration, so it feeds it back into the pump, damaging bearings and accelerating wear. Vibration also causes misalignment at the suction and discharge flanges, leading to leaks and premature spool failure. If operators have to tighten couplings regularly, vibration is usually the culprit.
Installation & Alignment Challenges
Rigid spools must be perfectly aligned. In practice, pump bases move and plant tolerances vary, making installation slow and dangerous. When two rigid spools and a coupling are used, installers must align three components exactly – any mis match will stress the flanges and create leading edge wear. Flexible spools are far easier to install: they can be stretched, compressed or rotated to bolt onto the pump.
Leaking Couplings and End Connections
The common arrangement of two rigid spools joined by a flexible coupling is a hotspot for leaks. Coupling misalignment lets slurry escape, creating safety hazards and messy clean ups. Pump vibration accentuates the misalignment and speeds up failure. Eliminating couplings by using one piece mining hose reducers removes this weak point and improves reliability.
How Beaver Solves the Pump Spool Problem
1. Use Flexible Mining Hose And Reducers
Beaver replaces rigid steel spools with Slurryflex mining hose and reducers. These hoses can flex axially, laterally and torsionally, allowing for misalignment and absorbing vibration. They dampen noise and vibration rather than transmitting it back to the pump.
2. Upgrade To Ceramic Lined CLX Spools For Severe Wear
For extreme abrasion, we use Slurryflex CLX ceramic lined reducers. Fine grain alumina tiles are embedded into the rubber hose, providing a seamless, impact resistant wear surface. The rubber carcass absorbs vibration while the ceramic tiles resist sliding abrasion.
3. Custom Engineer The Fit
Each spool or reducer is built to match your pump flanges and adjoining pipework. We can vary diameters, bore sizes and lengths to eliminate leading edge wear and optimise flow. Mining hose can be stretched, compressed or rotated to achieve alignment.
4. Simplify Installation And Maintenance
One mining hose replaces two rigid spools and a coupling. Hoses are lighter and easier to handle, reducing installation time and crane requirements. Fewer joints mean fewer leak points and a safer plant.
