ไดอะแฟรม ซีล , a quantity one innovator within the design, engineering and manufacturing of clever fluid-flow and control solutions, has launched a brand new version of its Design Envelope pump, specifically to serve in light-duty installations where the available power is single-phase.
Many smaller business and residential buildings use single-phase power. The standard method for these functions is often to put in a low-cost, light-duty circulator. While this meets the application necessities, many circulators are not repairable, and are designed for only a few years of operation.

The new Single-Phase Design Envelope pumps present practical and economical solutions for these installations and are now available for single part energy (200–230V) in sizes starting from zero.25 to 1.5kW.
Kevin Laidler – Sales Director, Middle East and Africa, comments: ‘These pumps are designed to ship elevated reliability, which in flip helps to scale back prices. They are built to follow the design commonplace for commercial pumps, so they are manufactured to final and can be economically repaired.’

As mechanical room piping for light-duty fluid-flow purposes is commonly installed vertically, the new single-phase pumps can be installed and operated in vertical piping.
Compared to conventional pumps that always depend on wall-mounted drives and commonplace induction motors, Design Envelope pumps present financial savings of up to 30% on operating prices via:
Adjustable design point and setpoint to match on-site conditions

Quadratic pressure management curve for max effectivity in variable-speed applications

Constant circulate operate to hold up a precise circulate price in recirculation applications

As with all our Design Envelope pumps, the new single-phase pump contains built-in intelligence and connectivity to assist Active Performance Management. The subscription-based Pump Manager service allows users to track pump status and performance, and can send alerts identifying issues similar to cavitation and dead-head. It additionally permits performance optimization through cloud-based analytics.
