Weir Mining Hoses, Weir Electric, and the Unexpected Lesson from a Tongue Scraper

7 Questions About Sourcing Weir Products I Learned the Hard Way

I manage purchasing for a 30-person engineering firm. We spec out weir equipment—mining pumps, hydraulics, the works—and I handle the ordering. Roughly $120K annually across 8 vendors. After 5 years in this seat, I've collected a list of FAQs I wish I'd known in 2020.

1. What exactly is a weir electric actuator, and where do I find one?

A weir electric actuator controls the opening and closing of a weir gate, sluice, or dam. It's a motorized unit that replaces manual cranking. For mining applications, you need something rated for heavy torque and slurry exposure.

Where to find one? Weir Group makes their own, but you can also source compatible replacements from industrial valve suppliers. Just verify the voltage (what we need: 24V DC or 120V AC?) and the duty cycle before ordering.

I learned never to assume "same specifications" meant identical results. Did that once with a supposedly matching actuator. Turned out the shaft keyway was 2 mm off. Wasted two weeks. Verify the exact part number with the OEM manual, not just the sales rep's word.

2. Is weir mining hose just fancy rubber pipe?

Yes—but with serious engineering. Weir mining hose refers to heavy-duty rubber or polyurethane hoses designed to handle abrasive slurry. Not like a garden hose. This stuff takes rock fragments, chemicals, and high pressure without bursting.

Look for hoses with reinforced inner linings. The standard spec is similar to all: 5-8 MPa burst pressure depending on diameter. But some knockoffs use lower-grade rubber that swells under chemical exposure.

A vendor once tried to sell me "industrial grade" hose that was really just truck air brake tubing. We caught it during inspection. Saved a $15K line shutdown.

Tip: Always request a material data sheet. If they can't provide one, walk.

3. Why would I need an engine hoist to install a weir pump?

Good question. The answer: Because these pumps weigh 600-2000 lbs depending on the model. An engine hoist (a.k.a. cherry picker) lets you lift the pump into place without tearing down the wall or renting a crane.

If you're doing your own pump change-out, a 2-ton floor crane is usually enough. Harbor Freight sells one for about $250. Not cheap, but compared to the $1,200 you'd pay a rigger? Worth it.

To be fair, not every shop needs one. But if you're maintaining multiple weir pumps on site, the ROI is real. Just make sure your floor can handle the weight. I still kick myself for not checking the concrete rating before attempting a lift. Cracked the slab. Cost me $600 in repairs.

4. Can I use a drill press for modifying weir components on-site?

Yes—within limits. A drill press is great for drilling weir gate mounting holes, pin holes in hinge brackets, or even modifying pump flanges. But don't expect it to machine hardened steel. Those slurry pump casings are tough.

For on-site repairs, a benchtop drill press with a variable speed drive and a mobile base is ideal. We use the Wen 4214. Reasonably priced ($120) and accurate enough for our needs.

But here's the catch: Most drill presses accept up to a 5/8" chuck. For larger fasteners on mining weirs, you're looking at 3/4" bit sizes. We had to buy an adapter collet set. Not a huge deal—but plan for it.

5. What about the tongue scraper? That seems off-topic.

It's not. Really. I included it because the search data shows people search "how to use a tongue scraper" constantly. And there's a connection: cleaning out your daily routine is like maintaining your equipment.

Using a tongue scraper: Place it at the back of your tongue, scrape forward 3-5 times, rinse. Takes 30 seconds. Reduces bad breath and clears bacteria.

Similarly, a daily weir pump inspection takes 2 minutes: check the shaft seal for drips, listen for bearing noise, verify the weir gate isn't stuck. A simple habit that prevents major failures. Keep your mouth clean, keep your pump running.

6. How do I know if a weir parts supplier is legit?

Here's what I check:

• Do they provide a proper invoice with a clear line-item breakdown? The vendor who gave me a handwritten receipt cost us $2,400 in rejected expenses from accounting.
• Can they provide proof of warranty? Written. Not a verbal promise.
• Do they know the Weir part numbering system? If they can't find the correct hose by a Weir part number, run.
• Have they done business with companies similar to yours? I asked for a reference from a mine with 400 employees. They provided one—quickly.

My biggest regret: not verifying their invoicing capability before the first order. Now I confirm billing format, terms, and everything upfront.

7. Is it better to go with a specialist weir vendor or a general industrial supplier?

Specialist, every time. Look, I get the appeal of a general supplier—one phone call, one shipment. But when that general supplier doesn't know why your weir mining hose is failing under 200 psi when it should handle 400 psi... that's a problem.

The vendor who said "this isn't our strength—here's who does it better" earned my trust for everything else. I'd rather work with a specialist who knows their limits than a generalist who overpromises. In my opinion, focus beats breadth for critical components.

That said, I use general suppliers for less critical items—like the drill press or engine hoist parts. For the weir electric actuator and hose? Specialist only.

This advice is accurate as of January 2025. Pricing and availability change fast in mining and industrial supply. Verify current specs with your OEM before placing any order.
