Commercial Pumps
Armstrong Fluid Technology provides high-efficiency, intelligent HVAC pumps—notably the Design Envelope (DE) 4300 Vertical In-Line series—designed to reduce installation, energy, and maintenance costs. These pumps feature integrated, sensorless variable speed controls, simplifying setup by eliminating external sensors and reducing floor space by up to 60% compared to traditional models.
Installation and Design Features
- Reduced Footprint: Vertical motor positioning requires up to 60% less floor space.
- Lower Installed Cost: Eliminates the need for concrete housekeeping pads, inertia bases, and many flexible connectors.
- Ease of Maintenance: Split-coupling allows mechanical seal replacement without removing the motor.
- Outdoor Applications: Controls are rated UL type 4x with weather shields, suitable for outdoor installation.
- Parallel Pumping: Often configured in parallel to optimize efficiency across part-load conditions (e.g., 50/50 flow split).
Key Technologies and Advantages
- Design Envelope (Sensorless): Algorithms calculate flow and head, providing intelligent control without needing external sensors, allowing for automated, energy-efficient performance.
- ARMSEAL: Specialized construction to prevent water leakage.
- System Integration: Supports modern Building Management Systems (BMS) with Wi-Fi connectivity on Gen 5 models.
- Wide Performance Range: Up to 28,000 USgpm flow and 500 ft head.
