Multistage pump (API 610 BB3)
Axially split multistage between-bearings pump: casing with stage bulges, back-to-back crossover and a heavy single row of studs with nuts on top of the horizontal split, side-side nozzles in the lower half (rotor lifts out without disturbing piping), casing vent and drain valves, seal chambers with API 682 Plan 23 seal coolers at both ends, bearing housings with X-Y probes, RTDs and ring-oil constant-level oilers (or pressure lube from the optional console), guarded spacer coupling and a 2-pole motor (HV with top air-to-air cooler from 1 MW) on a drain-rim baseplate. Stages, kW and nozzle sizes drive the length and frame.
Installation
Copies rotating/between-bearings-pump.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.
Usage
import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { BetweenBearingsPump } from './components/deck-twin/rotating/between-bearings-pump'
export default function Scene() {
return (
<Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
<Stage>
<BetweenBearingsPump />
</Stage>
<OrbitControls makeDefault />
</Canvas>
)
}

P&ID
Same centrifugal pump circle (tangential discharge, side suction), here with the driver drawn as a circle with M on the shaft. High-head water injection or export duty, often noted "multistage" or "BB3".
The symbol does not show between-bearings or multistage construction; pick this component when the title, datasheet or duty says multistage / BB3 / high head (e.g. water injection, pipeline booster). Otherwise use centrifugal-pump.

Or fetch /r/between-bearings-pump.json, or copy a ready-made instruction:
Add the Deck Twin "Multistage pump (API 610 BB3)" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add between-bearings-pump` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info between-bearings-pump` for its props, ranges and ports. Render <BetweenBearingsPump /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
