    API 610 Bearing system life --- is it a requirement or option?

    Maybe try the bearing forum..those guys get pretty analytical

    centrifugal pump code and standard

    At a large power plant, our feed pumps and booster pumps, and condensate pumps are api610 or meet the spirit of api610 :). Also other pumps that see elevated temps or considered "critical" are api610. Pumps that just move low-temp water around tend to be ANSI b73,1. If you have a specific...

    protect Vetrical Pump - on Earthquake

    As mjcronin already posted, Talk to one of the major manufacturers that have seismically-qualified nuclear safety-related pump designs. That would be flowserve, Sulzer, goulds, Hayward Tyler in the US. You're probably looking at seismic supports/rings near the bottom of the can.

    Need to Identify What a Part Is In a Pumping System?

    That may be an ANSI (b73.1) end-suction pump - or at least the bearing housing. Just search for b73.1 and you should be able to tell if it is built to ANSI dimensions.

    Low Temperature Flange Bolting

    You Sure your flange is big enough? My point is that you are missing adequate details for us to understand the problem.

    Baseplate Leveling

    it's a big deal for suspended pumps (soleplates). Might as well make it a big deal for installing all baseplates.

    pump flow rate

    Assuming you're not a rice farmer and that "flood" means an avg depth of 6" to make sure water gets everywhere...requires 4 acre feet in eight hours, or 2700 GPM. That's 100 HP imparted to the water, requiring about 150HP at shaft, 130 kVA in the line. Evaporation should be negligible compared...

    Duplex or Cuno strainer and differential pressure gauge should be pretty cheap.

    beaing isolator in pressure vessel

    You thought about a vertical installation? Not sure what's going on in there or how fast it is turning but I imagine you will need some radial bearings and a thrust bearing. maybe easier to suspend the rotor and have some low-load guide bearings.

    beaing isolator in pressure vessel

    Typically they are not designed for differential pressure of more than a few inches water. They are normally held in place with o ring and very light press fit. Me thinks you may need a mechanical seal. Or maybe a low pressure chamber with a throttle bushing to break down the pressure...

    Groove worn on wear ring surface at the eye of each impeller stage?

    Picture is too low resolution to tell...is the groove in a replaceable wear ring or in the impeller surface behind the wear ring?

    vertical very large 1 million gpm sea-water pumps

    For materials, see link below. For pumps of this size, You're probably looking at 316SS for stationary castings and super duplex or equiv for internals. Catholic protection will be considered. Vendors: All of the big names should have plenty of experience in this. Techniques to detect...

    Dissimilar metals for flange/bolt connections

    Surely the client is talking about corrosion of the flange, not the fasteners. Assuming normal outdoor installation, your setup sounds fine to me and fairly typical.
