Need help?Do you have a question about the Graco PRESIDENT 207-706 and is the answer not in the manual?
The Graco Hydra-Spray 30:1 Ratio President Pump is a high-performance, air-powered pump designed for industrial spraying applications, particularly those requiring high pressure. This device is capable of handling a maximum working pressure of 3600 psi (250 bar), making it suitable for a wide range of materials and demanding tasks. The pump is available in several models, including the 207-706 Series E for 55-gallon (200-liter) drums, the 207-707 Series D for 10-gallon (38-liter) drums, and the 217-578 Series A, also for 10-gallon (38-liter) drums, which features a Severe-Duty Displacement Pump.
The Severe-Duty Displacement Pumps (Model 217-578 Series A) are distinguished by their abrasion and corrosion-resistant displacement rod and sleeve, enhancing durability and extending the pump's lifespan when handling aggressive materials. Conversion kits (217-544) and displacement pumps (217-528) are available to upgrade standard 207-706 or 207-707 pumps to severe-duty configurations, offering flexibility and cost-effectiveness for users with evolving needs.
The pump is designed for ease of installation and operation. It requires a proper air supply and fluid lines, with clear instructions for connecting these components. The manual emphasizes safety, particularly regarding high-pressure fluid injection. Users are instructed to always follow the Pressure Relief Procedure before servicing, cleaning, or changing spray tips to prevent serious bodily injury. This procedure involves engaging the gun safety latch, turning off air to the pump, closing the bleed-type master air valve, disengaging the safety latch, relieving pressure into a grounded pail, and then opening the drain valve.
The pump's operation involves an air motor that drives a displacement pump, creating high-pressure fluid output. Troubleshooting guidance is provided for common issues such as low output on strokes, erratic operation, or pump failure, with solutions ranging from clearing restricted lines and refilling fluid supply to servicing internal components like packings and valve balls.
Regular maintenance is crucial for the longevity and optimal performance of the Graco President Pump. The manual provides detailed instructions for servicing, including:
The manual also includes parts drawings and lists for each model, facilitating the identification and ordering of replacement parts. Users are advised to provide the 6-digit part number, quantity, and part description when ordering from a Graco distributor. A mounting hole layout and dimensional drawing are provided for installation planning.
Safety is paramount with this high-pressure equipment. The manual contains numerous warnings regarding fluid injection, splashing, and moving parts. It stresses the importance of proper grounding to prevent static electricity discharge, which could ignite flammable materials. Users are warned against operating the pump with air motor plates removed due to the risk of pinching or amputating fingers. Regular checks for leaks, abrasion, corrosion, and damaged components are essential to ensure safe operation. The warranty information outlines Graco's commitment to quality and specifies conditions under which the warranty applies.
