The industrial applications of pumps have greatly changed the way machines work. At the helm of this transformation is the high pressure positive displacement pump (abbreviated as the PD pumps). Ever since their discovery, they have constantly been applied in machinery both in the traditional and modern setting.
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.
PD pumps way of working is entirely dependent on pressure and viscosity. They transmit fluids by trapping say an amount equal to its volume and moving it through a discharge pipe. The effect of these two properties is on the flow rate and efficiency. The main cause in their efficiency is their ability to keep a uniform flow despite unpredictable changes in discharge pressure and viscosity.
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 overall cost of pumping was greatly reduced when the PD pumps were put into use. Of shore drilling firms could now rack more in profits due to this.
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.
Paper mills usually dissolve the wood fibers and the resulting solution is used as a fuel for the boilers. This fuel needs to be pumped at a consistent rate. Viscosity of this solution keeps changing as it is burned while pressure also fluctuates wildly due to clogging in some passageways and erosion. A PD drive is therefore vital in ensuring that a constant rate of flow is maintained since irregular amounts of heat can distort the final quality of paper.
In conclusion, one should have a proper understanding concerning the physical properties of fluids to be moved and the expected changes in its properties during the process. This information would be vital on deciding which type of pumps to apply.
