Mechanical Seal Spiral Multiple Spring Burgmann Single Seal M74F For Water Pump

Q: Are you a factory or a trade company?
A: We’re a 100% real seal manufacturer based in Ningbo, with our own in-house export team. That means you get factory-direct pricing, full control over production quality, and our dedicated sales team will handle every step of your order smoothly. No middleman markup at all.

Q: Can I try to get a SAMPLE before the order?
A: Of course! Standard seal samples are totally free for you. You only need to cover the small international shipping fee. If you need a custom sample made to your specs, we’ll charge a tiny processing fee — and we’ll refund that fee fully once you place your formal bulk order later.

Q: Where is your factory located? How can I visit there?
A: Our factory is right in Ningbo, China. You can fly straight to Ningbo International Airport, or land at Shanghai Pudong Airport — it’s just a 2-hour high-speed train ride to our city. We’ll arrange free pick-up for you, and every overseas client is more than welcome to walk through our production lines anytime.

Q: How does your factory do regarding quality control?
A: Quality is non-negotiable for us. We check every single part from the moment raw materials come in, test semi-finished products on our test benches, and run a 100% pressure & leakage test on every finished seal before it leaves the factory. We’re ISO9001 certified, so you never have to worry about inconsistent quality.

Q: How about the lead time?
A: For all our standard mechanical seal models, we ship out within 10-20 working days after we receive your prepayment. If you need custom non-standard seals, we’ll give you a clear, exact timeline right after we review your drawing or sample, no hidden delays.

Q: How can we pay?
A: For small sample shipping fees, PayPal or T/T both work perfectly. For formal bulk orders, we use T/T at sight as our standard term. And for long-term regular clients, we can talk through more flexible payment options to fit your business needs.

Q: If OEM available?
A: 100% yes. We do full OEM and ODM services. We can make seals exactly to your samples, your engineering drawings, or even design a brand-new seal for you if you have special working condition requirements, like high temperature, strong corrosion or dry running scenarios.

Q: If I can buy pumps or pump parts from your company?
A: Absolutely! We’re your one-stop shop for all pump-related supplies. Besides our full range of mechanical seals, we also supply complete pumps and spare parts — including lobe pumps, compound homogeneous pumps, homogeneous emulsification pumps and more. This way you don’t have to source from 3 different suppliers, saving you tons of time and cost.
