Fracking pumps are pumps that are used in hydraulic fracturing processes. Fracking pumps are usually made up of the fluid end and power end. They are usually resistant to high pressure , high volume and harsh chemicals. Fracking pumps are used to pump in the fluid, containing sand and other particles, into the holes already drilled for extraction in the fracking process. Fracking pumps are usually powered either by electricity, gas or diesel.
There are different types of pumps that can be used as fracking pumps and they include; piston power pumps, direct acting piston pumps, metering pumps and diaphragm pumps.
The piston power pumps can be decided based on their orientation, their action, pump element and number of stages through which they function. They can either be vertical or horizontal, (depending on their orientation), single or double (according to their action), piston or plunger (based on their pump element) and simplex, duplex or triplex (based on the number of stages). Piston power pumps are highly efficient even at high pressures and low flow rate. They are expensive to install and maintain.
The direct acting power pumps are also referred to as the steam power pump and function in a straightforward manner without the need to convert rotational motion to linear motion to enable them function. This type of pump usually has two ends, the steam and the fluid end. It contains a lever that is attached to the piston rod for controlling the rate at which the steam flows from the beginning of the pumping process till when it is near the end.
Diaphragm pumps are used as fracking pumps because their pump cavities are quite suitable for transferring viscous and abrasive liquids and other materials. These types of fracking pumps are either powered by electrical, mechanical or hydraulic means. Diaphragm pumps are positive displacement pumps and, though they can be used as fracking pumps, they cannot be used extensively over a long period of time, due to the high pressure nature of the fracking system.
Fracking pumps are a necessity in the oil and gas industry especially during hydraulic fracturing. The operational mechanism of the fracking pump leads to wider fracturing of the earth, thereby allowing for easier passage of the oil through the pump and into the drilled oil well. They also help to make the fracturing process move faster and waste less resources.
Due to the abrasive nature of the liquids they transport, fracking pumps are usually made with materials that are highly resistant to corrosion. The cost of maintenance of fracking pumps is high because the different parts of the pumps need to be regularly checked and repaired to prevent wear and tear which is unavoidable over long term use.
The different types of fracking pumps all have one feature in common; they are able to function efficiently regardless of the pressure and flow rate of the pumping system. The discharge outlets of fracking pumps are usually very large to allow easy passage of the fracking liquid which consists of sand, water and other components which make the liquid thicker.
