Lubrication pump with improved priming handle assembly

摘要: A lubrication pump includes a piston and cylinder assembly comprising arranged for reciprocation within relative to having charging stroke discharging stroke, motor drivingly connected the priming means including handle coupled assembly. In order reduce risk of damage or parts downstream lubricant distribution system through excessively forceful use provide visual indication operation pump, resilient member is provided in coupling between such that movement move can take place without corresponding by deformation member.
