Design Envelope 4332 Tango Pumps
The Design Envelope 4332 Tango Pumps are engineered for optimal performance, energy efficiency, and serviceability, making them an ideal solution for HVAC systems, general-purpose pumping, and industrial/process applications involving water or glycol-based fluids.
Product Description
This pipe-mounted dual-pump unit integrates intelligent controls for a streamlined, space-saving installation that achieves outstanding energy performance. Designed for parallel pumping or full redundancy operation, the Tango Pumps can reduce energy consumption by up to 75% compared to traditional constant-speed or variable-speed pumps. With smart technology, they offer the flexibility and efficiency required in today’s high-demand environments.
Materials
The Tango Pumps are crafted with durable, high-quality materials:
• E-coated cast iron body for corrosion resistance and longevity.
• 316 stainless steel impeller, providing robust performance and resisting wear.
• Sintered silicon carbide mechanical seal, ensuring reliability even in demanding conditions.
Configuration & Intelligent Controls
Equipped with on-board Intelligent Variable Speed controls, these pumps offer Sensorless and Parallel Sensorless control options. This configuration ensures reliable performance across diverse applications, including UL Type 12 or UL Type 4X (for outdoor use) enclosures. Available with IE5 Ultra Premium Efficiency motors, they further optimize energy use. The design includes an outside-balanced mechanical seal for enhanced durability and maintenance ease.

Key Benefits
Lowest Installed Cost
• Compact Design: The dual-pump vertical in-line configuration eliminates the need for inertia bases, housekeeping pads, and flex connectors, saving space and costs. It also reduces the need for additional piping risers and pump trim.
• Integrated Controls: The intelligent controls eliminate the requirement for a separate variable frequency drive (VFD) and reduce procurement and installation costs by integrating wiring, calibration, and differential pressure sensors.
• Optimized Equipment Size: With DEPM motors, the Design Envelope selection often allows for a smaller motor and pump, reducing initial capital costs.
Lowest Operating Cost
• Ultra-Efficient Motors and Hydraulics: The advanced hydraulic design combined with DEPM motors provides IE5 Ultra Premium Efficiency, significantly lowering operating costs, especially in high turndown applications.
• Intelligent Energy Management: The integrated controls and precision component matching deliver up to 75% energy savings compared to traditional constant-speed and variable-frequency systems.
• Parallel Sensorless Control: This standard feature provides the most efficient staging of both pumps, maximizing energy savings.
Enhanced Serviceability and Zero Downtime
• Built-in Isolation Valves: Isolation valves on both suction and discharge sides allow one pump to be serviced without interrupting operation, ensuring continuous service.
• Convenient Service Features: Overhead lifting eyes make it easy to remove pump ends with integrated controls for maintenance, minimizing downtime and simplifying repairs.
Minimal Environmental Impact
• Lower Embodied Carbon: The Tango Pumps have up to 85% less embodied carbon than traditional two-pump end-suction setups, achieved through smaller equipment sizes and the elimination of bases, pads, extra piping risers, and connectors.
• Reduced Operating Carbon: The energy efficiency and Active Performance Management, including self-diagnostics, extend the pump’s operational life while reducing its carbon footprint.
• Efficient Packaging: The integrated design allows for more economical packing and shipping, reducing packaging waste compared to systems shipped with loose components.
