Armstrong Fluid Technology, Toronto, Ont, announces a new version of its Design Envelope Pump to serve light-duty installations where the available power is
single phase.
The new pumps are available for use with single-phase power (200 to 230V) from 1/3- to two-hp and are built to a design standard carried over from commercial pumps. In addition, since the mechanical room piping for light-duty fluid-flow applications is often installed vertically, these new single-phase pumps can be installed and operated with vertical piping.
