  What is negative suction in a pump? Negative suction in a pump refers to the scenario where the pump is drawing liquid up from below its centerline. We measure the space between the pump's centre and the liquid's surface in "head feet." It can be a negative value (below the pump) or a positive value (above the pump). In simpler terms, a negative suction head occurs when the surface of the fluid is below the level of the pumping unit. This is also referred to as a suction lift. The significance of negative suction in a pump lies in its impact on the pump's operation and efficiency. If not properly managed, negative suction can lead to issues such as cavitation, which is a common cause of pump failure. Cavitation occurs when there are changes in pressure within the pump, leading to the formation of vapour bubbles that can cause damage when they collapse. Therefore, understanding and managing negative suction is crucial for maintaining the efficiency and long...

An electrically operated double diaphragm pump (EODD pump) is a type of positive displacement pump that uses an electric motor as a power source to move fluids. These pumps are widely used in various industries, including mining, construction, and wastewater treatment. Slurry pumps, on the other hand, are a type of centrifugal pump that is designed to handle abrasive and corrosive fluids such as slurries, sludge, and thickened tailings. Slurry pumps are commonly used in the mining, oil and gas, and chemical industries. The efficient electrically operated slurry PD diaphragm pump with negative suction combines the advantages of both EODD pump s and slurry pumps. This pump is designed to handle abrasive and corrosive fluids efficiently while also being energy-efficient. One of the most significant advantages of this pump is its negative suction capability. This feature allows the pump to operate with a low NPSHr (Net Positive Suction Head Required), meaning that the pump can operat...
