Sensorless control for pumping systems

IPS 4000 operates in either a stand-alone mode or networked through the BMS to maximize performance.


Handles up to six pumps in 12 zones.

Handles up to six pumps in 12 zones.

Armstrong Fluid Technology’s IPS 4000, an integrated pumping system multi-zone control, optimizes energy performance, system handling and installation.

The control has a “sensor within” so it doesn’t rely on remote sensors to optimize the control of any variable flow HVAC system. With patented Best-Efficiency staging in a headered configuration, the IPS 4000 operates in either a stand-alone mode or networked through the BMS to maximize the performance profile of up to six pumps in 12 zones.

Key features and benefits include:

• Performance efficiency exceeding ASHRAE 90.1 2010, MEI 2015 compliant and achieves IE3.
• Easy installation and integration with existing HVAC systems.
• Field configurable by the user interface.
• Parallel sensorless technology.
• Enhanced performance data for optimized staging of pumps.
• Multi-zone control.
• Control of the by-pass valve in the de-coupler line, ensuring minimum flow rate requirements.
• Automates variable primary pump stations in response to changing number of chillers/boilers.
• Reads the flow from pumps, a flow meter or both.

Armstrong Fluid Technology, based in Toronto, makes intelligent fluid flow equipment.
