Simulated device. The PumpX-2000 is a fictitious product used by the PumpDeviceIntegrationServer sample of the OPC UA .NET Standard stack. It does not exist as hardware. Every figure in this datasheet is reproduced by the sample server's simulation and is asserted by tests/Opc.Ua.Di.Tests/PumpDatasheetConformanceTests.cs, so this document and the running address space cannot drift apart.

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 companion specification, layered on OPC 40001-1 Machinery and OPC 10000-100 Device Integration.

Both units are the same product; they differ only in serial number, fabrication number, asset identifier, component name and installation bay. The sample server materialises two units by default and derives the same per-unit fields for any further unit when started with --pumps N (SN-00n, PMP-100n, Feed Pump A/B/…, F-2025-000n, Bay n+2).

3.2 Characteristic curves

The pump is characterised by a quadratic head curve and a parabolic efficiency curve about the best efficiency point (Q in m³/h):

H(Q)  = 32.0 − 0.0104 · Q²                     [m]
η(Q)  = 72.0 · (1 − 0.6 · ((Q − 25) / 25)²)    [%]
Δp(Q) = ρ · g · H(Q)                           [Pa]
ṁ(Q)  = ρ · Q / 3600                           [kg/s]
P₂(Q) = ρ · g · (Q / 3600) · H(Q) / (η(Q)/100) [W]

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 (NPSH_A < NPSH_R)	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.
