Low flow high head pumps are also known as radial vane or partial emission pumps. This pump is a frame mounted, end suction, top centerline discharge, ANSI pump designed specifically to handle corrosive chemicals at low flows. It makes the flow outside the operating range of typical end suction pumps. They are designed to operate where standard end suction pumps operate poorly at throttled low flows. The high-head, low flow pump is without column piping and with an integral discharge connection and flexible-coupled electric motor. This pump is furnished, mounted horizontally, in the vertical position and usually has a flexible coupled solid-shaft motor.
