7 MAY 2021 WorldWide Drilling Resource ® Mud Pumps Keep HDD Operations Cool Adapted from Information by Gardner Denver Horizontal directional drilling (HDD) is used for many different projects. Utility contractors use this method to install cables and pipelines, while construction companies use HDD to place high- way ducts, and water lines under existing roads, rivers, or other sensitive areas. The gas and oil industry has used HDD technology to increase production from underperforming wells, and envi- ronmental remediation of contaminated sites is another beneficial use of HDD. The process involves boring a tunnel beneath the surface and placing a conduit in the bore- hole to pull the product into position. This reduces surface damage and eliminates the need for trenching. HDD pumps - also known as drill pumps, mud pumps, and high-flow pumps - are an essential component to HDD operations. Boring underground requires drilling fluid combining water and ben- tonite clay to remove cuttings, stabilize the borehole, cool the cut- ting tools, and lubricate the pipe string. Most mud pumps are positive displacement, reciprocating pumps comprised of a power end and fluid end assembly. A diesel engine or electric motor acts as the pump power source. The power end converts the rotation of the driveshaft to a recip- rocating motion by using a crosshead assembly. The fluid end uses this reciprocating action to achieve the function of pumping the pressurized mud. The fluid end assembly is comprised of a suction and discharge module, manifolds, pistons, liners, and valve assemblies. Most of the fluid end assembly components are high-wear items. The drilling pump rotates the drill bit which removes the material. As the drill bit is rotating, the pressure and fluid pro- duced by the drill pump help stabilize the tunnel. The mud extracted from this process is then filtered and reused for drilling fluid. A drilling pump should be able to provide a constant flow rate of fluid at a specific pressure. Over the past century, numer- ous mud pump design configurations have been introduced. The most common designs on the market today are duplex, triplex, and quintuplex models. The designs have horsepower ratings from 750 - 2400 horsepower.
