The revolution and diversification of industries can all be attributed to the invention of the pump. The applications of high pressure positive displacement pump has been extended well beyond the common usage of pumping water from a borehole. Modern industry relies heavily on this technology.
There are two main types that constitute the positive displacement pumps. These are the rotary and reciprocating pumps. They are both used when the main aim is to obtain a constant flow. Their main difference arises from the type of fluids they transmit. The rotary type is best suited for moving highly viscous fluids. This means that abrasive fluids will not be efficiently transmitted. Reciprocating types are well known for their ability to move both highly viscous and abrasive fluids with ease efficiently.
The efficiency and rate of flow of pumps is hugely dependent on two physical properties, that is, the viscosity of fluids and the pressure. The preference of PD pumps stems from their ability to maintain a constant flow rate given the ever changing physical properties.
Their applications are spread all over the facets of industrialization. One major use can be seen in the oil, gas and petroleum industry. Centrifugal pumps cannot move fluids that contain large amounts of gas. PD drives however have the capabilities of handling fluids with up to 50 percent gas without requiring any modification. Specialized PD drives can transmit fluids with up to 95 percent gas.
The properties above helped curb the cost of transmitting oil from offshore countries since oil and gas mixture could be pumped through one mechanism only.
PD pumps also found their application in the chemical industry. This typically involved the food and beverage industry and the pharmaceutical companies. Bio technology also uses these types of pumps. During a chemical process, when the chemical solution is passed through the reactor, certain attributes change due to heating and other reactions. This includes the viscosity of the mixture. The process however demands a constant rate of flow through the procedure. This is why they are applied in the chemical industry.
A similar application can be seen in paper milling industries. Paper mills are fueled by a mixture of fibers from the wood and liquid chemical. During the process the resulting mixture usually undergoes changes in density as it is burnt. Other problems such as clogging and erosion of passageways is also a common phenomena. Since the process of paper manufacturing is a highly regulated procedure, a constant flow of fuel is required. Using any other type of pumps despite these associated problems will not yield the required results. The reciprocating type pumps therefore offer the best solution for paper millers.
In summary, positive displacement pumps are the most efficient when rate of flow is a major requirement. One should properly understand all the physical properties of the fluid intended to be transmitted before settling on a choice of pumping mechanism.
