Key features include a 3/4" hollow shaft for seamless power source connection, a flow rate of up to 11.4 GPM, and a maximum pressure of 290 PSI. Constructed with durable polypropylene and Viton o-rings, it ensures longevity and resistance to harsh environmental conditions.

2. Safety Information

Read and understand all safety instructions before operating the pump. Failure to follow these instructions may result in serious injury or property damage.

• Always wear appropriate personal protective equipment (PPE) such as eye protection and gloves when handling chemicals or operating the pump.
• Ensure the pump is securely mounted before operation to prevent movement or vibration.
• Verify all connections (inlet, outlet, shaft) are tight and leak-free before starting the pump.
• Do not exceed the maximum rated pressure or flow rate of the pump.
• Never operate the pump dry. Ensure there is a constant supply of liquid to prevent damage.
• Disconnect power before performing any maintenance or adjustments.
• Dispose of chemicals and waste materials according to local regulations.

3. Product Features

The Annovi Reverberi AR45LFP-GR-GCI pump incorporates several design elements for reliable performance:

• Max Flow: 11.4 GPM
• Max Pressure: 290 PSI
• Inlet/Outlet: 1 1/4" Inlet / 1" Outlet
• Max Temperature: 140 Degrees F
• Shaft Type: 3/4" Hollow Shaft
• Power Requirements: 2.1 HP / 550 RPM
• Semi-hydraulic three-diaphragm design for smoother operation and reduced pulsation.
• Parts in contact with liquids are reinforced polypropylene, Kynar, and AISI 316 L for chemical resistance.
• Diaphragms made of BlueFlex and Viton for durability.
• Splash lubricated oiling system with a clear oil tank for visual level checking.
• Piston and ring design provides an efficient "oil cushion" system to protect diaphragms.
• Spherical sector profile valves offer lower flow resistance and improved volumetric efficiency.
• Heavy-duty mounting rails with AISI 304 SST fasteners.

5. Setup and Installation

1. Mounting: Securely mount the pump using the heavy-duty mounting rails. Ensure the mounting surface is stable and capable of supporting the pump's weight and operational vibrations.
2. Shaft Connection: Connect the 3/4" hollow shaft of the pump to your power source (e.g., internal combustion engine, hydraulic motor via gearbox or pulley fixtures). Ensure a proper and secure fit to prevent damage during operation.
3. Inlet Connection: Connect the 1 1/4" inlet to your fluid supply line. Use appropriate fittings and ensure all connections are tight to prevent air leaks, which can affect pump performance.
4. Outlet Connection: Connect the 1" outlet to your discharge line or spraying equipment. Verify all connections are secure and rated for the maximum operating pressure.
5. Oil Level Check: Before first use, and periodically thereafter, check the oil level in the clear oil tank. The oil level should be within the recommended range. Refer to the manufacturer's guidelines for the correct type and amount of oil.
6. Gauge Installation (Optional): If a pressure gauge is required, it must be purchased separately and installed according to its specific instructions.

6. Operating Instructions

1. Prime the Pump: Ensure the pump is fully primed with liquid before starting. Operating the pump dry can cause severe damage to the diaphragms and other internal components.
2. Start Power Source: Gradually start the power source connected to the pump shaft. Allow the pump to reach its operating RPM (550 RPM) smoothly.
3. Monitor Pressure and Flow: Observe the pressure gauge (if installed) and the flow rate. The pump is designed to deliver up to 290 PSI and 11.4 GPM. Adjust the power source or system valves as needed to achieve desired operational parameters within the pump's limits.
4. Continuous Operation: Maintain a consistent supply of fluid to the inlet during operation. Avoid sudden changes in pressure or flow.
5. Shut Down: To stop the pump, gradually reduce the power source RPM and then turn off the power. Close any necessary valves in the fluid lines.
6. Drain System: After use, especially when pumping corrosive chemicals or before storage in freezing temperatures, drain the pump and system thoroughly. Flush with clean water if necessary.

7. Maintenance

Regular maintenance is crucial for extending the life and ensuring the optimal performance of your AR45LFP-GR-GCI pump.

• Oil Level: Check the oil level in the clear reservoir before each use. Replenish or change oil according to the manufacturer's schedule and specifications.
• Diaphragm Inspection: Periodically inspect the BlueFlex and Viton diaphragms for signs of wear, cracking, or damage. Replace diaphragms as needed to prevent leaks and maintain efficiency. The three-diaphragm design and "oil cushion" system help protect them, but regular checks are still important.
• Valve Inspection: Inspect the spherical sector profile valves for debris or wear that could impede flow or reduce volumetric efficiency. Clean or replace as necessary.
• Connection Integrity: Regularly check all hose and pipe connections for tightness and signs of leakage. Tighten or replace fittings as required.
• Cleaning: After using corrosive or viscous liquids, flush the pump with clean water to prevent buildup and corrosion.
• Storage: When storing the pump for extended periods, especially in cold climates, ensure it is thoroughly drained and protected from freezing.
