The Spike Flow is a robust pump system designed to facilitate various liquid transfer tasks, particularly in brewing applications. Its primary function is to circulate liquids efficiently and safely, ensuring a smooth and controlled flow throughout the brewing process. The pump is engineered for ease of assembly and operation, making it suitable for both experienced brewers and those new to the craft.

Function Description:

The Spike Flow pump is a centrifugal pump, meaning it uses a rotating impeller to move fluid. It consists of a pump motor, a drive magnet, a motor adapter, a rear housing, an impeller, a front housing, and an air release valve (ARV). The pump motor provides the power to rotate the drive magnet, which in turn spins the impeller within the front housing. As the impeller rotates, it creates a low-pressure area at the inlet, drawing liquid into the pump, and a high-pressure area at the outlet, pushing the liquid out. This magnetic drive design eliminates the need for a shaft seal, reducing the risk of leaks and making the pump more durable and easier to clean. The ARV is a crucial component that allows for the removal of trapped air from the pump head, ensuring efficient operation and preventing the pump from running dry, which could cause damage. The pump is designed to handle hot liquids, making it ideal for transferring wort during brewing, recirculating cleaning solutions, or moving other liquids that require controlled circulation.

Usage Features:

The Spike Flow offers several features that enhance its usability and performance. The pump head is designed to be rotatable, allowing users to adjust the outlet direction by slightly loosening the 3-inch tri-clamp. This flexibility in orientation is beneficial for optimizing hose routing and setup in various brewing configurations. The pump can be operated either on the ground or securely mounted to a brew stand using its integrated mounting holes, providing versatility in setup.

For optimal performance, it is recommended to direct the pump outlet upwards (as shown in Figure 1 of the manual). This orientation facilitates the bleeding of air from the system, which is essential for efficient and damage-free operation. The manual emphasizes the importance of bleeding air by unscrewing the ARV a couple of turns until liquid emerges from the bleed port, then re-tightening it. This priming process ensures that the pump is filled with liquid before it starts running, preventing dry running that can lead to rapid wear and damage.

The Spike Flow is designed to work in conjunction with flow control valves. It is advised to attach a ball valve to the outlet of the pump or the inlet of the kettle to regulate the flow. Ball valves are recommended over butterfly valves for their superior control. A critical operational guideline is to never throttle the flow before the pump. Throttling should always occur from the outlet side. Restricting flow on the inlet side can cause the pump to run dry, even if there is liquid in the system, leading to potential damage.

To further optimize flow and prevent air entrapment, users are advised to minimize hose lengths and avoid large loops or dips, especially on the inlet side. These measures help ensure a continuous and unobstructed flow of liquid into the pump, reducing the chances of air pockets forming. The bleed port on the ARV is designed to accommodate 1/2-inch ID tubing, allowing users to recover any wort lost during the air bleeding process, minimizing waste.

The pump is equipped with a power switch for easy on/off control. Before starting the pump, it is crucial to ensure that all hoses are empty and all valves are closed. The process of filling the pump involves opening the drain valve on the kettle to allow liquid to fill the hosing between the kettle and the pump, thereby priming the pump with liquid. Only after the pump is primed should all valves between the pump outlet and the kettle be opened.

The manual provides recommended flow configurations, illustrating "Best," "Ok," and "Bad" setups for the pump. These visual guides help users orient the pump correctly to maximize efficiency and minimize operational issues. The "Best" configurations typically show the ARV positioned at the highest point, facilitating air removal.

Maintenance Features:

Maintaining the Spike Flow pump is straightforward, contributing to its longevity and reliable performance. After each brew day, the pump can be cleaned by disassembling it and soaking its parts in a brewery wash. This thorough cleaning ensures that all components are free from residue and contaminants. An alternative cleaning method involves running hot brewery wash through the pump for approximately 5 minutes, which can be a quicker option for routine cleaning.

A specific maintenance tip relates to the o-ring on the ARV. This o-ring comes pre-lubricated with keg lube, but over time, it may dry out, making the ARV difficult to turn. If this occurs, users are instructed to completely unscrew the ARV and apply fresh keg lube to the o-ring. This simple step ensures smooth operation of the ARV, which is vital for effective air bleeding and overall pump performance.

A crucial maintenance and operational guideline is to never run the pump while it is dry. Running the pump without liquid can quickly cause significant damage to its internal components, particularly the impeller and housing. Therefore, proper priming and ensuring a continuous liquid supply are paramount for the pump's health. Regular inspection of hoses and connections for leaks or blockages is also recommended to prevent dry running and maintain optimal flow. By following these usage and maintenance guidelines, users can ensure their Spike Flow pump remains a reliable and efficient tool for many brewing sessions to come.
