We can tweak the sizing or labeling on these if your setup needs something different—just let me know what you're working with, but most buyers go with the standard dimensions because they're already a known fit for common pump housings.
What it basically does is handle high pressure really well for a balanced mechancial seal, and the SIC rotary ring gives it that extra durability edge—it's not a one-size-fits-all solution though, since it's better for water, oil, or mildly corrosive chemicals than anything aggressive like strong acids.
1.2 MPa is teh pressrue ceiling, and the temperature range sits at -20°C to 120°C, which is solid for most industrial setups but you'll want to check if your media runs hotter or has a higher viscosity since that can push the limits on the 10m/s speed rating.
The stationary ring choices—ceramic, SiC, or CAR—and the rotary ring options like carbon or SUS304 give you some flexibility, but we usually have the SIC/CAR combo in stock because that's what most pump repair shops ask for, roughly 20 days or so lead time on custom runs.
One thing we've noticed from handling these: the NBR secondary seal holds up better in oil-based application than EPDM, so if you're pumping hydrocarbons, don't default to EPDM unless you've got a specific reason (like temperture tolerance).
Anyway, the MOQ is usually 50 units or so for the standerd version, and we provide COA with HPLC data —just keep in mind these aren't designed for food-grade or pharmaceutical use without further testing on your end.
You can choose Carbon, SiC, CAR, or SUS304 for the rotary ring, depending on your application needs.
It handles up to 1.2 MPa, which covers most standard industrial applications without issues.
Yes, we can provide material certifications and a quality inspection report upon request for each batch.
For standard sizes, lead time is usually 7-10 days after order confirmation, depending on quantity.
Absolutely, we offer both SS304 and SS316 spring options, just let us know your preference when ordering.
