For a long time, pumps have changed the way machinery operates. The high pressure positive displacement pump is at the forefront of this. On the onset of its invention, it has been used in both the traditional and modern society.
The rotary and reciprocating pumps constitute the two main classes of pumps. They are similar in that they both allow a constant rate of flow but different in a functional point of view. Rotary pumps require constant lubrication through the pumping process. Their suitability with highly viscous fluids is the corner stone of their operation. They however cannot transmit abrasive fluids like water and gas efficiently. Vaporized fluids can be pumped but for only limited periods of time. Reciprocating pumps on the other hand are more all rounded because they are better suited for both viscous and abrasive liquids.
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.
The most monumental applications of PD pumps is in the oil industry. Here they mainly serve to pump the crude oil from the extraction site to the processing site. It was initially expensive to separately pump the constituents of the extracted matter which included the oil, gas, water and sand. This was largely due to the fact that it contained significantly large amounts of gas. However the ability of reciprocating pumps to transmit gases came in handy. The mixture was now being transmitted as it was without the need of building separate pumping stations for each element.
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.
Its applications can also be extended to the chemical process industry. These include the pharmaceuticals, food and beverage production and biotechnology. A typical chemical process is usually accompanied by major fluctuations in the physical properties of the initial mixture such as viscosity. Since PD pumps maintain a constant flow rate despite these unpredictable changes, it is the most suitable for transmitting the fluid through the reaction chambers.
Considering the high amounts of paper in use in an economy, PD drives contribution to its manufacture is worth the mention. The entire process of paper milling is a highly regulated industry. This implies that any lag in function of a unit would in a varied number of ways hamper the production process. Pumps function is to keep a constant supply of fuel in a system. The constant changes in viscosity and clogging implies that the positive pumps would be the most suitable for the job.
As a parting shot, each and every aspect of the transmitted fluid should be analyzed before choosing which pumps to use, however the PD pumps have been seen to be efficient at maintaining the rate of flow.
