Fields Of Application :

The up series comprises horizontal single stage centrifugal pumps, specially designed for the pumping of thermal fluids at a high temperature, in industrial installation, without needing any type of external refrigeration. The hydraulic characteristics of pumps are in accordance with the standard DIN 24 256 (ISO 2858) for chemical pumps.

Pumped Liquids

All kinds of heat transfer liquids.

Design

From the hydraulic point of view, the ATP pumps are centrifugal single stage, horizontal, volute type pumps. With regards to the mechanical design, the main concept of the ATP series is to a maximum, the mechanical seal and ball bearing from the source of heat that constitutes the pump casing, placing between both a thermal barrier and cooling the mechanical seal housing and bearing support by natural convection.

Pump Casing

The impeller of the ATP pumps are single entry, closed type and dynamically balanced. The impeller has back Ring & Holes between each fins for the axial balancing of pressures.

Shaft And Support

The impeller is overhung mounted on the end of the end the shaft. The shaft is designed to be able to withstand all mechanical and thermal efforts generated during operation of the pump with minimum deflection. The bearing housing is made of cast iron and apart from serving as the shaft support; it also houses the mechanical seal. It is equipped with external cooling wings.

Shaft Seal & Bearings

Shaft sealing is obtained by means of a high security mechanical seal, placed in the bearing housing, close to the second ball bearing near to the shaft end. This means that the seal is housed in allow temperature zone, given the distance from the pump casing, thus obtaining a long life for the seal. The first ball bearing near to the casing is lubricated by pumped liquid. A safety stuffing box with a following throttling area is arranged in front of the first ball bearing and mechanical seal. Even in case of failure of the mechanical seal, these additional safety elements prevent seepage from emerging in a hazardous quantity and manner. The second ball bearing is located near the end of the shaft and lubricated by grease for life.
