DUBAI, UAE, 28 February 2022: Armstrong Fluid Technology has launched a new version of its Design Envelope pump for the Middle East region. Making the announcement through a Press release, the company added that the pumps are intended specifically to serve in light-duty installations, where the available power is single-phase.

Many smaller commercial and residential buildings use single-phase power, Armstrong said, adding that 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 company further added.

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

Kevin Laidler, Sales Director, Middle East and Africa, said: “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, Armstrong said. Compared to conventional pumps that often rely on wall-mounted drives and standard induction motors, the new 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, and constant flow function for maintaining a precise flow rate in recirculation applications, the company added.

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