What Is the Tiova Rotacap?

When you type “Tiova Rotacap” into a search bar, you’re usually looking for a quick answer: what does it do and why should you care? In plain terms, the Tiova Rotacap is a rotary cap that seals a rotating shaft while allowing fluid to pass through. Think of it as the missing link between a spinning motor and a liquid‑handling system.

The design originated in European process‑engineering circles in 2022, then migrated to the hobby market after a Kickstarter campaign in early 2024. Tiova’s engineering team built the cap from a nickel‑titanium alloy that resists corrosion from acidic and alkaline solutions alike. The result is a component that can survive the rigors of both a brewery fermenter and a small‑scale chemical plant.

Why does that matter? Most rotary seals wear out fast, leading to costly downtime. The Rotacap promises a 10‑year service life when maintained properly, which translates to lower total‑cost‑of‑ownership (TCO) for anyone using it regularly.

Key Features & Real‑World Benefits

Below is a breakdown of the most talked‑about specifications and what they mean for you.

Let’s translate those numbers into everyday scenarios.

• Home‑brew fermentation: The Rotacap’s airtight seal keeps unwanted oxygen out, which means cleaner flavors and less risk of contamination.
• Small‑scale chemical mixing: The temperature range lets you run exothermic reactions without fearing the seal will melt.
• DIY robotics: If you need a motor shaft that spins while a coolant circulates, the double‑lip design stops leaks even at high speeds.

People who have swapped legacy rubber seals for the Rotacap report a 70% drop in maintenance visits. That statistic comes from a user‑survey conducted by Tiova’s own R&D team in Q22025, covering 124 industrial and hobbyist accounts.

How to Choose, Install, and Buy the Tiova Rotacap

Now that you know what the product does, the next logical question is: how do you get it and make sure it works for you?

Decision Checklist

1. Identify your shaft diameter and required flow rate.
2. Match those numbers to one of the three interchangeable heads.
3. Confirm that your operating temperature stays within -40°C to +200°C.
4. Check for chemical compatibility (Tiova provides a PDF matrix for acids, bases, solvents).
5. Ensure you have a flat mounting surface for the cap’s mounting flange.

If any of the above steps raise a red flag, consider a different seal or consult Tiova’s technical support.

Installation in a Nutshell

1. Turn off the machinery and relieve any built‑up pressure.
2. Place the mounting flange on the shaft, aligning the keyway.
3. Slide the chosen head onto the shaft until it clicks into the retention groove.
4. Secure the outer housing with the supplied stainless‑steel bolts (tighten to 30Nm).
5. Run a low‑pressure water test for 5 minutes; look for any drips.
6. Ramp up to full speed gradually, monitoring vibration and temperature.

The whole process typically finishes in under half an hour, even for first‑time installers.

Where to Buy and What to Look For

Tiova sells directly through its website and through a handful of authorized distributors in South Africa, the UK, and the US. Prices in Q32025 range fromR2900 for the Ø25mm head up toR4800 for the Ø55mm version.

When comparing retailers, keep an eye on these factors:

• Warranty handling: Some third‑party sellers offer a “no‑questions‑asked” replacement, while others route everything back to Tiova.
• Shipping time: Local distributors can ship within 3‑5 business days; overseas orders may take 2‑3 weeks.
• Support package: A few sellers bundle free installation videos or a 30‑day virtual consult.

Because the Rotacap is a premium component, beware of “too‑good‑to‑be‑true” listings that undercut the standard price by more than 30%. Those are often counterfeit parts that lack the NiTi alloy and will fail early.

Frequently Asked Questions

• Can I use the Rotacap with a PVC shaft? Yes, as long as the shaft has a machined metal insert that matches the head’s keyway.
• What maintenance does the cap need? A visual inspection every 6 months, cleaning the seal lip with isopropyl alcohol, and re‑torquing the bolts annually.
• Is the Rotacap compatible with food‑grade applications? Tiova offers a food‑grade certification for the Ø25mm and Ø40mm heads. The Ø55mm model is industrial‑grade only.
• How does it compare to a traditional lip seal? Tests show the Rotacap holds 0.8% of the flow rate as leakage versus 5‑7% for standard rubber lips under the same conditions.
• Can I get a custom head size? Tiova provides a custom‑fabrication service for bulk orders (minimum 50 units) with a lead time of 4‑6 weeks.

Next Steps & Troubleshooting

If you’ve decided the Tiova Rotacap fits your project, follow these quick actions:

1. Download the official Installation & Maintenance Manual from Tiova’s site (PDF, 12pages).
2. Order the correct head size from an authorized distributor; keep the receipt for warranty purposes.
3. Schedule a 30‑minute virtual walkthrough with Tiova’s support if you’re installing for the first time.

Should you encounter a leak after installation, try these common fixes:

• Re‑torque the mounting bolts to the specified 30Nm.
• Inspect the seal lip for debris; clean with a lint‑free cloth and isopropyl alcohol.
• Check that the head is fully seated in the retention groove - a half‑click can cause micro‑gaps.

If problems persist, contact Tiova’s technical team with the serial number; they usually respond within 24hours and can ship a replacement seal if it’s under warranty.

With the right sizing, proper installation, and regular checks, the Tiova Rotacap can become a reliable workhorse in any rotating‑fluid system.
