Abstract
A pump particularly for pumping abrasive and/or chemically aggressive liquids includes at least one rotating pumping member having a respective shaft, the at least one rotating pumping member being at least partially housed inside a pump body. The shaft is rotatably supported by at least one support associated with the pump body. The shaft and the at least one support are both at least partially made of a material having a hardness greater than or equal to 5 Mohs, where the material having a hardness greater than or equal to 5 Mohs is located at least in the areas of the shaft and of the support in mutual contact.
Claims14
A pump for pumping abrasive and/or chemically aggressive liquids, the pump comprising:
- at least one rotating pumping member comprising a respective shaft, said at least one rotating pumping member being at least partially housed inside a pump body, said shaft being rotatably supported by at least one support associated with said pump body, wherein said shaft and said at least one support are both at least partially made of a material having a hardness greater than or equal to 5 Mohs, said material being located at least in the areas of said shaft and said at least one support in mutual contact.
The process for assembly a pump for pumping abrasive and/or chemically aggressive liquids, comprising at least one rotating pumping member comprising a respective shaft, said at least one rotating pumping member being at least partially housed inside a pump body, said shaft rotatably supported by at least one support associated with said pump body, wherein said shaft and said at least one support are both at least partially made of a material having a hardness greater than or equal to 5 Mohs, said material being located at least in the areas of said shaft and said at least one support in mutual contact, said at least support comprising at least a bush, the method including the following steps:
- inserting said at least a bush inside a corresponding housing seat present in said pump body, and
- deforming the portion of material of which said pump body is made at said housing seat to fix said at least a bush in said housing seat.
