The HT and VHT models are multi-stage centrifugal pumps. The number of stages depends on the required head. The number of stages is variable, and the pump running wheel can be adapted to match the specific capacity required within the range covered by the pump size.
The standard pump comes in cast iron or bronze, dimensioned for TN 16, but can be tailored for other pressure ranges or made from other materials, if required.
The pump has a stainless steel shaft, firmly seated in greased ball bearings in the coupling side. In the suction side the shaft is seated in a medium-lubricated support bearing made from a special material. The pump has only one stuffing box with a mechanical shaft seal. The shaft seal can be replaced without dismounting the pump from the system. The pump and motor are connected by an elastic coupling.
Areas of application
The high pressure provided by the pump at revolutions of only 1,500 r/min. makes it suitable for many different applications. The number of revolutions in a technically correct installation in terms of flow ensures high pump efficiency, a low NPSH, long service life, and a low noise level.
