FAQ’s
Your Questions Our Answers
Pump diaphragms push fluid and take a beating from constant cycling. Valve diaphragms flex to open/close flow and give you a tight shut-off. Different job, different design.
Yes — it’s what we’re known for. The fabric layer stops the rubber from stretching out of shape and makes it last a lot longer under pressure.
Natural or synthetic rubber — NBR, EPDM, Neoprene — reinforced or plain, bonded to metal, plastic, carbon or PTFE depending on what you need.
DN08 to DN350 across the XE, XB, XC, XF and KB types.
Yes, both — they’re part of this same range.
Three things really matter: temperature, what chemicals it’ll touch, and how hard it’ll be worked. Tell us that and we’ll narrow it down fast.
Yeah, send us the old part or a drawing and we’ll reverse-engineer it — often better than the original.
