Which pumps run at variable speed, how large, and with which drives?哪些泵能变频、做到多大、配什么变频器？
All three makers offer variable speed in two forms.三家都提供两种变频方式。
Drives built into the pump are stated up to 22–55 kW (Armstrong to 450 hp); larger plant pumps use separate drives.一体式驱动写明到 22–55 kW（Armstrong 到 450 hp）；更大的冷站水泵配独立变频器。

drive on the pump驱动装在泵上 pump without a built-in drive, largest motor泵上不带变频器的泵，最大电机 separate drive, largest size独立变频器，最大规格
Largest size each source states, in kW; hp is drawn at 0.746 kW unless the source gives kW. Armstrong's 4300 family runs to 1,250 hp (900 kW), but its drive sits on the pump only up to 450 hp indoors; above that it has standalone control. Wilo TERA-SCH: largest article listed (Wilo states IE3 motors to 1,000 kW). The Grundfos sources read here do not state KPVS motor sizes, and Wilo Korea gives no power for its Wilo-Sensorless pump with an integrated inverter, so neither is drawn. Sizes are not efficiencies or duty points.各来源写明的最大规格，单位 kW；来源未给 kW 时按 0.746 kW/hp 换算。Armstrong 4300 系列到 1,250 hp（900 kW），但驱动装在泵上只到室内 450 hp，再往上为独立控制。Wilo TERA-SCH：所见最大型号（Wilo 写明 IE3 电机至 1,000 kW）。这里读到的 Grundfos 资料未写明 KPVS 电机规格，Wilo 韩国也未给出带集成变频器的 Wilo-Sensorless 泵的功率，所以两者都未画出。规格不是效率，也不是工况点。

Willow Lei · judgementWillow Lei · 判断
All three makers offer variable speed in two forms: pumps with the drive built in, stated here up to 22 kW at Wilo, 55 kW at Grundfos and 450 hp at Armstrong (4300, indoors), and larger plant pumps that get variable speed from a separate drive, such as split-case pumps (Armstrong 4600 to 400 kW; Wilo TERA-SCH articles seen to 450 kW) and the 4300 above 450 hp.
The separate drives differ: Grundfos's CUE reaches 560 kW with BACnet built in and Armstrong's IVS 102 1,250 hp, while the Wilo sources read here state the Wilo-EFC to 132 kW without mentioning BACnet, and CC-HVAC panels to 45 kW per pump (higher on request) with an optional BACnet module; on the CDU side, in the sources read here, only Wilo names a supply, about 240 Atmos GIGA-B pumps (standard motor, no built-in drive) on DCX units, and DCX states that Wilo's pumps and VFDs are integrated across its FDUs (facility coolant distribution units).
In my judgement, for AI sites the question is no longer whether a pump is variable-speed, but how pumps, drives, the CDU and the plant are controlled together when GPU load swings; none of the sources read here gives data on that.
三家都提供两种变频方式：驱动装在泵上的一体式变频泵，这里写明的最大规格为 Wilo 22 kW、Grundfos 55 kW、Armstrong 4300 室内 450 hp；更大的冷站水泵则靠独立变频器调速，例如中开泵（Armstrong 4600 到 400 kW；Wilo TERA-SCH 所见型号到 450 kW）以及 450 hp 以上的 4300。
独立变频器各不相同：Grundfos CUE 到 560 kW、内置 BACnet，Armstrong IVS 102 到 1,250 hp；这里读到的 Wilo 资料写明 Wilo-EFC 到 132 kW、未提 BACnet，CC-HVAC 控制柜每泵到 45 kW（更大功率可询）、可选配 BACnet 模块；这里读到的资料中，CDU 侧只有 Wilo 点名供货：DCX 设备上约 240 台 Atmos GIGA-B（标准电机，泵上不带变频器），DCX 称 Wilo 的泵和变频器已集成在其 FDU（设施侧冷却液分配单元）中。
我的判断是：对 AI 机房，问题不再是泵是否变频，而是 GPU 负载波动时，泵、变频器、CDU 和冷站如何协同控制；这里读到的资料都没有给出这方面的数据。
