Abstract
A blade set for masserating effluent solids in a sewage pump is composed of a cutter ring and a wheel blade adapted to attach to an effluent water inlet at the lower base. Particularly, the cutter ring has an inner wall and multiple recesses defined on the inner wall to accept enhancing blocks made of tungsten carbide. Correspondingly, the wheel blade has multiple blade strips and each blade strip has a cutout defined at edge to combine with an enhancing corner also made of tungsten carbide. By having the structure made of tungsten carbide, the cutter ring and the wheel blade has excellent wearing resistance and less abrasion loss to keep the operational efficiency to masserate the effluent solids and to extend the lifespan of the sewage pump.
