our company can do custom shaft configurations and extended lead times for non-standard voltages, but the standerd build is 380V at 50Hz with a ±5% tolerance window — most pump users just go with the 4KW rating and 1500RPM from that 4-pole design anyway.
It's basically a cast iron workhorse for industrial pumps, and the IP55 protection level means it shrugs off water jets and dust without fuss, though you can get IP56 if your environment is really nasty. The sealed bearings on this frame size are a plus, but for larger frames you're looking at open types (usually 2-4 weeks lead if you want sealed custom).
Interesting detail nobody thinks to ask: the F-class insulation actually handles a steady 40°C ambient with a 80K overtemperature rise, so you're not losing efficiency when the pump room heats up, and it'll run at 4KW all day without complaint.
85% or so efficieny at full load — IE3 class — which is tighter than most older EFF1 designs, and that matters when you're paying the electric bill on a bank of pumps running 24/7. We always have the standard B3 foot-mount version in stock, but B5 or B35 flanges add maybe 10 days or so to ship date.
Not suited for outdoor installations in salt spray or chemicla washdown areas unless you spec the optional IP56 and special paint finish, or you'll be looking at corrosion inside a year or so. We've seen that happen with buyers who tried to save a few bucks on a covered dock application.
Our standard MOQ is 10 units per model, but we can negotiate lower quantities for first-time orders or sample requests. Just let us know your needs.
Lead time is usually 15-20 working days for standard orders, depending on stock levels. Custom configurations may add a few extra days.
Yes, we include copies of the ISO9001 and CCC certifications with every order. We can also send them in advance for your review.
Absolutely—the YE3-112M-4KW supports B3, B5, and B35 mounting types. Just specify which one you need when placing the order, and we'll set it up accordingly.
The motor can be stored safely at temperatures from -25°C to +55°C. Keep it in a dry, covered area to avoid moisture buildup.
