These types of systems utilize a suction mechanism to draw water from a canal. The positioning of the cart within the system, whether at the end or in the center, depends on factors such as canal placement and the area to be irrigated. It’s crucial for the cart’s path to maintain minimal deviation from the canal’s water level to prevent issues like pump cavitation due to low water levels or air accumulation in the suction tube in cases of high water levels.

To accommodate the increased energy demand for water pumping, the cart’s fuel tanks boast larger capacities (ranging from 1,700 to 2,000 liters) compared to other systems. Various suction system options are available, including simple filters, self-cleaning filters, electric winches, and electric priming pumps.
