Rutan pump 250w Submersible pump 50m head

The Rutan 250W Submersible Pump with a 50m head is a very popular and specialized water pump in Kenya, primarily known for its efficiency with solar power. It’s designed for deep well applications and off-grid water supply.

Here’s a detailed overview:

Key Features and Specifications of the Rutan 250W Submersible Pump (50m Head):

• Power Input: 250 Watts (W). This indicates its electrical consumption.
• Voltage: Most commonly 24V DC (Direct Current), making it highly compatible with solar panel systems. Some variations might be available in 12V DC, but 24V is prevalent for this specific model and head.
• Maximum Head (Lift): 50 meters (m). This is the maximum vertical distance the pump can push water upwards. This makes it suitable for deep wells, boreholes, or moving water to elevated tanks. Note that 50m is approximately 164 feet.
• Maximum Flow Rate: Typically around 1500 Liters per Hour (L/Hr) or 1.5 cubic meters per hour (m³/h). This indicates the volume of water the pump can deliver. For a 250W pump with a 50m head, this is a decent flow rate, suitable for small to medium-scale needs.
• Outlet Diameter: Usually 25mm (1 inch). This is the size of the pipe connection for the water discharge.
• Material: Often constructed with a stainless steel body and a copper motor. This provides durability and corrosion resistance, essential for submersible pumps operating in water.
• Operating Principle: Being a DC pump, it’s designed to connect directly to solar panels. Many models emphasize that they do not require an external battery bank or a solar charge controller for operation during daylight hours. They can also be operated using a 24V battery system if continuous supply (e.g., at night or during cloudy days) is needed.
• “Run Dry” Protection: A significant feature highlighted for Rutan pumps is their ability to run dry without sustaining damage, eliminating the need for a float switch in some applications.
• Installation: Designed to be installed vertically (in a borehole) or horizontally.
• Cable Length: Often comes with a substantial cable length, for instance, 14 meters or 20 meters, to facilitate deep well installation.
