High temp. magnetic pump

The utility model discloses a high temperature magnetic pump, relating to the improvement of the structure of the magnetic pump. The right side of the support seat (2) of the utility model is fixed with a heat dissipation body (9). A sealing sheath (7) is fixed between the support seat (2) and the heat dissipation body (9). A magnetic shaft (8) is arranged in an outer bracket (3), the heat dissipation body (9), a pump head (11) and an end cover (14). A graphite bearing sheath (10) is fixed on one side in the heat dissipation body (9) and slidingly connected with the magnetic shaft (8). A fluorine thermoplastic bearing sheath (12) is fixed on the other side in the heat dissipation body (9) and slidingly connected with the magnetic shaft (8). A pump head graphite bearing sheath (20) is fixed in the pump head (11) and slidingly connected with the magnetic shaft (8). The end cover graphite bearing sheath (21) is fixed in the end cover (14) and slidingly connected with the magnetic shaft (8). The utility model can be used for the equipment, such as the reaction kettle heated by oils, injection mould, chemical engineering, etc., and can work stably under the high temperature of 250-300 DEG in long time. The high temperature magnetic pump has the advantages of simple structure, convenient operation, stable performance, high-temperature resistance, low noise, good sealing effect, long service life and low maintenance cost.
