The GRACO 224914 is a lower pump assembly designed for use in Dyna-Star hydraulic reciprocating pump systems. It is engineered for optimal performance and durability, intended to transfer oil or grease in bulk or for auto-lubrication in various industrial applications. The wetted parts are constructed from steel, copper, polyurethane, buna-N, and polyester elastomer.

Key Features:

• Hydraulic reciprocating pump (lower pump assembly)
• 5:1 Dyna-Star, 35 LB
• Steel, copper, polyurethane, buna-N, polyester elastomer (wetted parts)
• Maximum output flow rate: 4 lb/min (with No. 2 grease at 60 cpm, 3000 psi)
• Maximum hydraulic fluid input pressure: 1500 psi; Maximum grease output pressure: 7500 psi
• Designed for use with GRACO Dyna-Star hydraulic reciprocating pump systems
• Reliable, quiet, and ice-free performance at maximum pressure and low-flow rates
• Up to three times more energy efficient than comparable compressed-air systems
• Engineered for durability and optimal performance
• Ease of maintenance and robust duty cycle

Applications:
Used for transferring oil or grease in bulk or for auto-lubrication in various industrial settings, including mining, agriculture, and manufacturing.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and longevity of the equipment.
• When purchased separately, the displacement pump (224914) comes with the priming piston and priming cylinder un-assembled—follow the manual for proper assembly.
• Ensure hydraulic supply inlet (3/8" NPT), hydraulic return outlet (3/4" NPT), and fluid outlet (1/2" NPT) are correctly connected.
• Do not exceed maximum incoming fluid temperature of 130°F (55°C).
• Regularly inspect and maintain wetted parts for wear and proper function.
