<p>A pump assembly for an emergency eyewash station and method of retrofitting a plumbed emergency eyewash station is disclosed. The pump is configured into two parts, an impeller assembly (10, 112) and a drive assembly (28, 102), that are configured to couple together. The impeller assembly (10,112) is isolated from the drive assembly (28, 102) and can be easily replaced to ensure a sterile fluid path is maintained for the eyewash fluid. The drive assembly (28, 102) can be fluid powered (28) or an electric motor (106) as desired. The present invention allows a plumbed eyewash station (26) to be retrofitted to use a sterile eyewash fluid. The present invention can also be used in portable eyewash station units (200) too.</p> |
