![]() It is best for high-pressure requirement applications. These pumps are not best for high-flow applications because it produces a low flow rate. They are most commonly used in petrochemical, oil & gas, refinery, agriculture, and fertilizer industries.Īdvantages and Disadvantages of Reciprocating Pump Advantages Disadvantages It creates large pressure than a centrifugal pump. The reciprocating pump is one of the most effective types of pump. The inlet and outlet sides have a check valve for preventing the backward flow of the liquid. After filling the cylinder, the inlet valve closes, and the discharge stroke starts.ĭuring the discharge stroke, the outlet valve opens, and pressurized liquid discharges from the outlet valve. During the suction stroke, the cylinder is filled with fresh liquid. This type of pump pumps the fluids in two strokes: suction stroke and discharge stroke. The crankshaft is connected to an electrical motor or engine that helps to rotate the crankshaft. ![]() The piston or plunger is connected to the crankshaft through a connecting rod. The piston or plunger moves downward and upward inside the pump cylinder. These types of pumps use a plunger or piston to transfer the fluids. The classification of the positive displacement pumps is given below: 1.1) Reciprocating Pumps ![]() ![]() The positive displacement pumps are further divided into multiple types. These pumps don’t need manual priming because they have self-priming ability. They operate by trapping a specific amount of liquid in the pump chamber through an inlet valve and expelling it via the discharge valve. The moving parts of these pumps discharge the fluid from the pump housing and increase the hydraulic pressure at the same time. The positive displacement pumps most commonly use moving parts (such as gears, lobes, plungers, pistons, or rotors) to transfer the fluids. Main Article: Positive Displacement Pumps Dynamic Pump 1) Positive Displacement Pump.The pumps have the following major types: T he main difference between them is that they are used for different working fluids. The low pressure on the pump’s inlet side causes the fluid to rise from a particular depth and the high pressure on the outlet side pushes the fluid to the desired head.Ī pump has similar working to a compressor. All types of pumps work by producing a low-pressure area on the inlet side. They are usually worked by a vacuum in which air pressure pushes the liquid out. Pumps are driven by means of different power sources such as wind power, solar power, engine, or manual operation. In general, heavy equipment needs lower suction pressures and high discharge pressures. You can easily find them with heavy equipment. The hydraulic pump can also be utilized in processes that require high hydraulic pressure. The pumps most commonly convert electrical energy into hydraulic energy to transfer fluids. What is a Pump?Ī pump is a mechanical device that is used to transfer different fluids (gases or liquids) from one location to another by applying mechanical action. In this article, you will learn the different types of pumps, the working of the water pump, and the function of the pump. The pumps have multiple types designed according to the requirements of different applications. They most commonly convert electrical energy into hydraulic energy. Pumps are used to transfer fluids from one area to another. What are the Symptoms of Water Pump Failure?.How can we identify, Pump is pumping or not?. ![]()
