Armstrong Fluid Technology launches new single-phase pumps in the Middle East

Armstrong Fluid Technology, a leading innovator in the design, engineering and manufacturing of intelligent fluid-flow and control solutions, has launched a new version of its Design Envelope pump, specifically to serve in light-duty installations where the available power is single-phase.

Many smaller commercial and residential buildings use single-phase power. The conventional approach for these applications is often to install a low-cost, light-duty circulator. While this meets the application requirements, many circulators are not repairable, and are designed for only a few years of operation.

The new Single-Phase Design Envelope pumps provide practical and economical solutions for those installations and are now available for single phase power (200–230V) in sizes ranging from 0.25 to 1.5kW.

Kevin Laidler – Sales Director, Middle East and Africa, comments: ‘These pumps are designed to deliver increased reliability, which in turn helps to reduce costs. They are built to follow the design standard for commercial pumps, so they are manufactured to last and can be economically repaired.’

As mechanical room piping for light-duty fluid-flow applications is often installed vertically, the new single-phase pumps can also be installed and operated in vertical piping.

Compared to conventional pumps that often rely on wall-mounted drives and standard induction motors, Design Envelope pumps provide savings of up to 30% on operating costs through:

• Adjustable design point and setpoint to match on-site conditions
• Quadratic pressure control curve for maximum efficiency in variable-speed applications
• Constant flow function to maintain a precise flow rate in recirculation applications

As with all our Design Envelope pumps, the new single-phase pump includes built-in intelligence and connectivity to support Active Performance Management. The subscription-based Pump Manager service allows users to track pump status and performance, and will send alerts identifying issues such as cavitation and dead-head. It also enables performance optimization through cloud-based analytics.
