## 1 Product description
The PumpX-2000 is a single-stage, end-suction, radially split centrifugal pump
for clean and lightly contaminated liquids in utility and process-water duty.
The hydraulic end is close-coupled to a foot-mounted asynchronous motor; the
bearing bracket carries a temperature probe and the discharge nozzle carries a
combined pressure/flow transmitter assembly.
The pump is instrumented as an OPC UA asset. It exposes its nameplate, its
process values and its supervision states through the
[OPC 40223 Pumps](https://reference.opcfoundation.org/specs/OPC-40223) companion
specification, layered on
[OPC 40001-1 Machinery](https://reference.opcfoundation.org/Machinery/v102/docs/)
and [OPC 10000-100 Device Integration](https://reference.opcfoundation.org/DI/v104/docs/).

## 7 Monitoring, supervision and alarms
### 7.1 Trip points
The bearing-temperature chain is monitored by a `NonExclusiveLimitAlarmType`
instance published at `Events/OverTempAlarm`. Its `SourceNode` is the
`BearingTemperature` variable and its limits are the datasheet trip points:
| Limit | Value | Equivalent | Action |
|---|---:|---|---|
| `HighHighLimit` | 373.15 K | 100 °C | Trip — stop the pump |
| `HighLimit` | 363.15 K | 90 °C | Alarm — reduce load, check cooling |
| `LowLimit` | 283.15 K | 10 °C | Warning — lubricant below operating viscosity |
| `LowLowLimit` | 278.15 K | 5 °C | Warning — risk of freezing |
The alarm is acknowledgeable; the sample accepts every acknowledge request.
### 7.2 Supervision states (NAMUR-style)
| Supervision variable | Browse path | Set condition | Reset condition |
|---|---|---|---|
| Motor overheat | `Events/SupervisionPumpOperation/MotorOverheat` | Bearing temperature ≥ 363.15 K (90 °C) | Bearing temperature < 361.15 K (88 °C) |
| Cavitation | `Events/SupervisionProcessFluid/Cavitation` | Suction level < 2.10 m (NPSHA < NPSHR) | Suction level > 2.20 m |
`MotorOverheat` drives the activation of `OverTempAlarm`; the resulting
condition events are delivered through the `HasNotifier` chain from the pump to
the `Server` object.

## 8 Simulation profile
The sample server reproduces the datasheet with a deterministic model driven by
a single independent variable — volumetric flow. Every other published value is
derived from the characteristic curves in section 3.2, so the published values
are mutually consistent at all times. The simulation advances on one shared
250 ms tick; each pump uses a fixed phase offset of 17 ticks per instance so the
units never move in lockstep.
| Signal | Model | Simulated range |
|---|---|---|
| Flow | `Q(t) = 25 · (1 + 0.30 · sin(0.03 · t))` | 17.50 … 32.50 m³/h |
| Differential pressure | `ρ · g · H(Q)` | 205.7 … 282.1 kPa |
| Mass flow | `ρ · Q / 3600` | 4.85 … 9.01 kg/s |
| Efficiency | `η(Q)` | 68.1 … 72.0 % |
| Shaft power | `ρ · g · (Q/3600) · H(Q) / η` | 2.01 … 2.73 kW |
| Bearing temperature | `323.15 + 10 · (P₂/P₂,BEP) + cooling-fault excursion` | 331.5 … 378.2 K (58.4 … 105.1 °C) |
| Fluid temperature | `313.15 + 5 · sin(0.01 · t)` | 308.15 … 318.15 K (35 … 45 °C) |
| Suction level | `2.5 + 0.5 · sin(0.02 · t)` | 2.00 … 3.00 m |
| Start counter | one start per 15 simulated minutes | monotonic |
*Cooling-fault excursion*: every 64 ticks (16 s) the simulated bearing-cooling
water is interrupted for the last 8 ticks (2 s), ramping the bearing temperature
linearly by up to +43.75 K. The excursion crosses both the `HighLimit` and the
`HighHighLimit` trip points, so a full alarm activate/clear cycle — including the
`MotorOverheat` supervision transition — is observable roughly every 16 seconds.
*Cavitation*: the suction level sine dips below the 2.10 m NPSH threshold once
per level cycle (≈ 78 s). Because the state only clears again above 2.20 m, the
`Cavitation` supervision state is held for approximately 19.6 s (78 ticks) per
cycle.
