Quick Answer
A hand pump can be enhanced with accessories such as a pressure tank, filter systems, and a foot valve to improve its usability and efficiency. Additionally, a pump gauge and a pressure switch can also be used to monitor and control the system. These accessories help to ensure a steady water supply.
Pressure Tank and Filter Systems
A pressure tank is a crucial accessory for a hand pump, especially in off-grid systems. It stores excess water pumped by the user, allowing the system to maintain a consistent water pressure. When the tank is full, the pump shuts off automatically, preventing over-pumping and reducing the wear and tear on the pump. We recommend a pressure tank with a minimum capacity of 20 gallons. A filter system can also be integrated with the pressure tank to provide clean drinking water.
Pump Gauge and Pressure Switch
A pump gauge helps to monitor the water pressure in the system, ensuring that it remains within a safe operating range. This is especially important in systems where water pressure can fluctuate due to changes in demand or pump performance. A pressure switch can be used to automatically turn the pump on and off, based on the pressure in the tank. We recommend installing a pressure gauge with a range of 0-100 psi and a pressure switch with a set point of 30-40 psi.
Foot Valve and Other Accessories
A foot valve is a simple yet essential accessory that prevents air from entering the pump when it is not in use. This helps to maintain the system’s water pressure and prevents the pump from being damaged by airlock. Other accessories that can be used with a hand pump include a priming bulb, a pump handle extension, and a water storage tank with a float valve. These accessories can help to improve the efficiency and convenience of the hand pump, making it easier to use and maintain.
