“If our crew won’t put it on a truck we’re building, we won’t put it on yours.”
What this site is
Superior Water Truck Parts is the catalog and ordering surface for the parts inventory we run at our Phoenix yard. Everything we sell here is sourced and stocked by the same crew that builds finished water trucks at our parent company, Superior Equipment Inc. Pumps, valves, spray heads, hose reels, water cannons, cab controls, tanks, complete build kits — if it goes on a working water truck, we carry it.
The reason it’s a separate brand instead of just a parts page on the Superior Equipment site: parts buyers and truck buyers are different audiences. A fleet manager needs a B3Z-S mechanical seal today, ships tomorrow, no negotiation. A truck buyer is in a multi-week purchase cycle. Different sites, different surfaces, different speed.
Why we have a different inventory philosophy
We use the parts ourselves
Every SKU we stock goes on the trucks our parent company builds. We’re the customer of our own catalog. If a part isn’t good enough for our builds, we don’t stock it for yours.
Mech-seal only
We only stock mechanical-seal pumps and parts — the modern standard. Rope-seal pumps are still out there in the field, but they’re not what we build with and not what we sell.
Real photos, real specs
The photos on each product page are the actual part as it sits on our shelf. Specs are what the part actually does, verified by the crew that uses it.
Fitment-first conversations
We’d rather take 5 minutes on the phone to confirm fitment than send you the wrong part. Call before you order if you’re not sure — we know the questions to ask.
How we sell
Three paths to get a part:
- Order online — add to cart, pay by card. Stripe-hosted checkout coming online soon. Most orders ship same-day from Phoenix if placed before 1pm AZ.
- Call us — (602) 437-3980. Especially for big-ticket items (pumps, cannons, build kits) where a 5-minute fitment call beats a wrong-part return.
- Fleet account with NET-30 — for fleets running 2+ water trucks or parts resellers. Consolidated monthly invoicing, dedicated phone line, priority service. Open a fleet account →
Phoenix yard pickup
If you’re in the Phoenix metro, parts are usually ready for same-day pickup at our yard by 2pm AZ. 156 E Mohave Street, Phoenix AZ 85004. Open Mon–Fri 7am–5pm. Drive in, talk to the crew, leave with the part. Bring the truck if you want fitment verified on the spot — we’re working trucks every day; an extra one in the yard isn’t a problem.
