US 6,190,261 B1 · Pump assembly shaft guard

Abstract

A shaft guard is provided comprising a first guard portion, a second guard portion, and a pair of support legs. The first guard portion defines a first guard body, a first pair of guard portions, and a first pair of flange portions. The first guard body is arranged about a longitudinal shaft guard axis. The first pair of guard portion openings are positioned at opposite ends of the longitudinal shaft guard axis. The first pair of flange portions are arranged on opposite sides of the longitudinal shaft guard axis. Similarly, the second guard portion defines a second guard body, a second pair of guard portions, and a second pair of flange portions. The second guard body is arranged about the longitudinal shaft guard axis. The second pair of guard portion openings are positioned at opposite ends of the longitudinal shaft guard axis. The second pair of flange portions are arranged on opposite sides of the longitudinal shaft guard axis. Respective ones of the first pair of flange portions are secured to opposing ones of the second pair of flange portions to form respective mated flange pairs such that the respective ones of the first pair of guard portion openings complement opposing ones of the second pair of guard portion openings to form a pair of shaft guard openings positioned at opposite ends of the longitudinal shaft guard axis. The pair of support legs are secured to at least one of the first and second guard portions.
