Quick Answer
A Flojak hand pump is designed to handle water weights up to 30 kg (66 pounds) per stroke, but this can vary depending on the pump model, well depth, and usage.
Pump Capacity and Weight Limits
When using a Flojak for a well, it’s essential to consider the weight limit to ensure efficient operation and longevity of the pump. A well-designed Flojak can handle water weights up to 30 kg (66 pounds) per stroke, but this can be affected by factors such as the pump’s model, well depth, and usage. For example, the Flojak 400 model has a maximum recommended water weight of 30 kg per stroke, while the Flojak 600 model can handle up to 45 kg (99 pounds) per stroke.
Calculating Well Capacity and Pump Size
To determine the correct Flojak model for your well, you’ll need to calculate the well’s capacity in liters per minute (L/min). This can be done using the formula: Well capacity (L/min) = Well diameter (mm) x Well depth (mm) x 0.0075. For example, a well with a diameter of 150 mm and a depth of 50 meters would have a capacity of approximately 7.5 L/min. Based on this calculation, you can select a Flojak model that can handle the well’s capacity.
Installation and Maintenance Best Practices
To ensure efficient operation and extend the lifespan of your Flojak, it’s crucial to follow proper installation and maintenance procedures. This includes installing the pump at a depth of 1-2 meters below the water surface, ensuring the pump is properly primed, and regularly inspecting and maintaining the pump’s moving parts. Additionally, it’s recommended to perform a thorough cleaning and lubrication of the pump every 6-12 months to prevent corrosion and wear.
