The new GD 800HDD pump (photo) has an extremely high flowrate of more than 1,000 gal/min, making it suitable for the most demanding horizontal directional drilling (HDD) projects. Its light weight eases transportation between work sites and its extremely high rod-load rating of 53,000 lb ensures the pump is tough and long lasting, says the manufacturer. The pump is also designed to operate at a slow run speed, delivering the same output, flow, and pressure as faster pumps with less violent actions, wear and friction. By delivering fewer strokes, consumable life is extended. The pump is qualified as maxi-rig pump, and can provide a suite of options to the HDD industry when tunneling under rivers and roads and laying sewerage systems, water pipes, fiber-optic lines and pipelines. — Gardner Denver (GD) High Pressure Solutions, Houston
