Abstract

A fluid spraying system includes a displacement pump configured to mount to a drive housing. A reciprocating drive is connectable to a pump rod of the displacement pump and includes a connecting rod and a drive link that receives a head of the pump rod. A tightening ring that includes threading is configured to rotate about a cylinder of the pump and shift axially along the cylinder and engage with a bottom side of the drive housing to secure the displacement pump to the drive housing.
