A pump is a device that moves fluids by means of mechanical action. High pressure process pumps move the fluid by trapping a given fixed amount and displacing the trapped amount through the discharging pipe. They are more preferred to their counterparts the centrifugal types since their capacity is not affected by the pressure under which they operate. They are also known as constant volume pumps and are divided into three main categories namely the rotary, reciprocating and linear drives. These classifications are usually made according to the mechanism used to transmit the fluid.
Rotary drives are used in situations where the liquid that is being moved is thick or in scientific terms possesses a high level of viscosity. They cannot therefore be operated dry for extended durations. This would imply that abrasive fluids such as water will not be transmitted with the required efficiency. The only exception is air and vapor but this also has to be done under strict time constraints. Circulation of lubricant oils through turbines and engines is a common application of the rotary pumps.
Reciprocating drives on the other hand are considered more versatile due to their ability to move both viscous and abrasive fluids. Operation is by means of the back and forth action of a plunger usually within a fixed volume. They are generally slower than the other types but they however provide higher efficiency levels. Usage is highly based on situations that require high levels of strain but low volumes of the fluid.
Linear drives are simplistic in design but still retain their ability to perform the task required of it. One would only need a rope, a wheel and a piece of PVC piping to construct one. Since these materials are readily available, its use has spread all around the world. It serves as a pump for water from wells and boreholes.
Installation is major factor in ensuring maximum utility of the pumps. Proper installation would usually imply that the pumps will be able to operate at their best. Every manufacturer has a mandate to ensure that proper guidelines are provided to aid in the installation process.
Constructing a solid foundation is however intuitive and can be done prior to the purchase. A good foundation is based on reinforced concrete. Heavier units usually require stronger foundations. Once the unit is brought it is fitted on a steel base plate that has been fastened to the concrete slab. All that is required now is a step by step application of the user manual to complete installation.
Factors that determine the choice of the pump can be divided into two; the viscosity of the fluid and the pressure needed. Changes in viscosity can have huge implications on the flow rate and efficiency. These might be slight, huge or even moderate changes.
Fluctuations in pressure levels also greatly affect the efficiency and rate of flow. The best choice therefore would be one that keeps a constant rate of flow whilst maintaining efficiency even with ever changing pressure levels. Pressure pumps are therefore ideal due to their ability to address these two concerns.
