<p>Applicant: Vaughan Co., Inc. Title: High Head Centrifugal Slicing Slurry Pump A booster propeller is located at the inlet of a flared funnel leading toward arcuate inlet apertures in an end plate of a centrifugal pump casing. The pump impeller is received in a bowl capped by the end plate and has a circular shroud plate perpendicular to the axis with vanes or blades projecting toward the end plate and having cupped leading surfaces forming a sharpened edge. Such blades are swept back in the area of the end plate inlet apertures for effective slicing of chunks or lumps of solid material in the slurry in combination with sharpened leading edges of the inlet apertures.</p> |
