The FLOJET BevJet Compact is a specialized beverage dispensing pump designed for use in enclosed environments where precise control over fluid delivery is essential. As a positive displacement diaphragm pump, it is engineered for applications requiring consistent flow rates and automated shut-off features. This guide provides a detailed overview of the installation, operation, and maintenance of the BevJet Compact, based on the manufacturer’s installation and operation manual.
Installation Requirements and Procedures
The BevJet Compact is intended for use in enclosed systems that protect the pump from exposure to water, spills, or outdoor elements. Installation must be carried out in accordance with the instructions provided by the manufacturer to ensure proper operation and longevity of the device.
To begin the installation process, the suction hose (6.35 mm, or 1/4 inch in diameter) must be connected to the source container, which can be either a bulk container (BIB) or a bottle. The power supply is provided via a supplied power adapter, which must be connected to the DC plug located on the rear of the pump. Once connected, the ON/OFF switch on the pump must be set to the “ON” position.
A critical step in the installation process is priming the pump. This is done by opening the discharge valve, allowing the pump to draw liquid through the system and expel air from the line. The pump is equipped with a built-in timer that prevents dry operation for longer than one minute and automatically shuts off the pump after five minutes to prevent continuous operation without liquid flow. These features help protect the internal components from damage due to overheating or dry running.
According to the manual, the pump must be installed in a protected enclosure to prevent exposure to splashes or spills. The manual also explicitly warns against placing the BevJet Compact into a dishwasher, as this can cause electrical failure of the pump and its control systems.
Operational Guidelines and Safety Precautions
The BevJet Compact operates using a combination of mechanical and automated controls. The pump is designed to deliver fluid with minimal user intervention, thanks to its built-in dry-run and wet-run timers. However, users must be aware of the system's limitations and adhere to the safety precautions outlined in the manual.
One of the most important safety warnings is the prohibition of outdoor use. The pump is not rated for exposure to weather conditions and must be installed in an enclosed space. Additionally, the manual emphasizes that the pump should not be used in environments where flammable vapors are present, and it must only be used with liquids that have a flash point above 100°F (37.8°C). This warning is clearly labeled as an explosion hazard and must be taken seriously.
During operation, the pump must be monitored for signs of malfunction. If the system fails to dispense fluid, potential issues include an incorrect ON/OFF switch position, lack of power, disconnected tubing, or an empty container. In such cases, the user is advised to cycle the switch to reset the system or check for air in the line.
If the system fails to shut off automatically, users should inspect the tubing for leaks and purge the system of air. Another common issue is the pump turning on and off repeatedly during operation. This behavior is often caused by restricted flow due to kinked tubing or undersized or excessively long tubing. The manual recommends ensuring that the tubing diameter and length are appropriate for the system's flow requirements.
Maintenance and Storage Considerations
To ensure the longevity of the BevJet Compact, users must follow the manufacturer's maintenance and storage guidelines. A key consideration is the need to purge all liquid from the pump before cleaning, servicing, or storing the unit. This is particularly important in environments where freezing conditions may occur. If water or other liquids are allowed to remain in the system and freeze, it can lead to internal damage to the pump and associated plumbing.
The manual also cautions against the use of any cleaning agents or methods that may compromise the electrical integrity of the pump. Specifically, placing the pump in a dishwasher is not permitted and may result in permanent damage to the internal components.
For storage purposes, the pump should be kept in a dry, temperature-controlled environment. When the pump is not in use for an extended period, it should be disconnected from the power source and all fluid lines should be emptied. This helps prevent the buildup of residue or bacterial growth, which could affect the performance of the pump when it is reactivated.
Troubleshooting Common Issues
The manufacturer provides a troubleshooting guide to help users diagnose and resolve common problems that may occur during operation. One of the most frequently reported issues is the pump failing to dispense fluid. This can be caused by a variety of factors, including incorrect switch settings, power supply issues, or disconnected tubing. Users are advised to check each of these components in sequence and verify that the fluid container is not empty.
Another common issue is the pump failing to shut off after the expected time period. This may indicate the presence of air in the system or a leak in the tubing. In such cases, the manual recommends purging the air from the line and inspecting the tubing for any visible signs of wear or damage.
If the pump continues to turn on and off repeatedly during use, this is typically a sign of flow restriction. Users should check for kinks, bends, or obstructions in the tubing and ensure that the tubing diameter is appropriate for the system's flow rate. The manual also notes that excessive tubing length or undersized tubing can cause similar issues and should be corrected.
Technical Specifications and Design Features
The BevJet Compact is a compact and lightweight device, making it ideal for use in space-constrained environments. The pump is powered by a DC power supply, which is provided via the included power adapter. The use of a DC power source ensures stable and consistent operation, even in environments where power fluctuations may occur.
The pump is designed with a positive displacement diaphragm mechanism, which allows for precise and repeatable fluid delivery. This type of pump is particularly well-suited for applications where flow rate consistency is critical, such as in beverage dispensing systems.
One of the key design features of the BevJet Compact is its built-in dry-run and wet-run timers. These timers help prevent damage to the pump by limiting the duration of dry operation and automatically shutting off the system after a set period of continuous use. This feature is especially important in systems where the fluid source may be intermittently available or where the pump may be subject to frequent start-stop cycles.
Compatibility and System Integration
The BevJet Compact is designed to be compatible with a variety of beverage dispensing systems. It can be integrated with both bulk container systems (BIBs) and individual bottles, making it a versatile option for different types of fluid sources. The pump’s suction hose is sized at 6.35 mm (1/4 inch), which is a standard size for many beverage dispensing systems.
The manual also includes a diagram of a typical beverage installation, which illustrates how the pump can be connected to the fluid source and dispense line. This diagram provides a visual reference for users during the installation process and helps ensure that all connections are made correctly.
In terms of tubing requirements, the manual notes that the maximum run length depends on the diameter of the tubing. For 3/8 inch inner diameter tubing, the maximum recommended run length is 10 feet. This helps ensure that the pump can maintain adequate flow rates without excessive pressure drop or flow restriction.
