the choice between water-cooled and oil-cooled solar pumps depends on your specific needs and circumstances. Water-cooled systems offer better cooling and are more space-efficient, but they come with higher maintenance costs and potential noise issues. Oil-cooled systems are simpler to install and maintain but are less efficient in cooling and require careful waste oil management.
When calculating head, avoid misconceptions. The head is not just the vertical height or pipeline length. It's essential to consider flow rate, total pipeline length, diameter, and material, balancing initial investment against operating costs.Pump head = vertical height + pipeline loss + outlet pressure
