An engine pump assembly (), particularly a main coolant pump, composed of a housing () of a rotary pump with delivery elements arranged therein, a heat barrier part (), a motor part () which drives the delivery elements, and force transmitting connecting elements () between a housing flange () of the housing () of the rotary pump and a flange () of the engine part (). For faster and more reliable assembly and disassembly, the housing flange () is provided with receptacles () over at least half of its periphery for the arrangement of screw heads () of the connecting elements (), which screw heads () are held in a bayonet-like manner in the receptacles ().

Main coolant pump

An electric motor () having a coaxially associated pump () for a coolant circuit, in particular in a system with temperature transfer and/or heat transfer, in which a shaft assembly () transmits a torque from the electric motor () to at least one impeller () arranged in the pump housing () within housing parts () in the form of a hermetically sealed pressure enclosure, and a flywheel () is arranged between the electric motor () and the pump housing (). All of the rotating parts are arranged within a hermetically sealed motor/pump unit, and the motor/pump unit is filled with fluid. The flywheel () comprises a flywheel body () made from a high-strength material having a large number of cavities () with inserts () formed of or containing a heavy metal having a density greater than 11.0 kg/dmarranged in the cavities.

Electric motor having a coaxially associated pump

The invention relates to a compensator modular unit for a multistage pump housing, ensuring as compensation device during hot or cold temperature shocks compensation of changes in length caused by said shocks.

Compensator

A centrifugal pump system for moving hot media includes a pump section, a motor section and mounting elements holding the pump and motor sections together. A force is formed by the mounting elements that is transmitted between the pump section and the motor section. A heat barrier is positioned between the pump section and the motor section. The heat barrier includes an insulating ceramic element. The force transmitted between the pump section and the motor section is transferred through the ceramic element.
