Leave blank for all. Otherwise, the first selected term will be the default instead of "Any".

Square tanks are more stable for a given size than round tanks. Square tanks are also more user-friendly because a simple addition of handrails creates a safe work platform. Special grating schemes must devised on round tanks to allow the addition of a personnel walkway on the top of the tank. Because square tanks are more expensive to manufacture, however, they are not often used.

The PLC allows the dredge to interface with the processing plant and boosters, and also allows different automation schemes to be employed. The PLC has revolutionized the hydraulic control system. It has allowed the hydraulic oil, valves and hose to stay in the hydraulic room or engine room, so they no longer reside in the control room or lever room. For more information about automation and controls, please see our Automation page.

A submerged pump, in a nutshell, raises production due to increased suction inlet pressure—even at shallow depths and low production rates. Economic issues usually dictate the decision of whether to purchase a ladder pump or not. Without adding an elaborate jet system in the pump suction, which is very inefficient and costly at or near sea level, if you plan to dig deeper than 45 feet and need to average more than 300 tons per hour of production, it is more cost effective to use a ladder pump or a combination ladder pump and hull-mounted pump. At DSC, any of our sales staff, with the help of one of our four licensed professional engineers, will gladly do a project analysis to help you choose the most cost-effective dredge to satisfy your production needs.

Required horsepower is dependent on pressure and flow rate. At a given flow rate, more horsepower is required on the long line than a short line. This is because a higher pressure is required to pump a longer pipeline at a given flow. At a given pump speed, more horsepower is required on a short line than a long line. This is because the lower friction on the short line induces a higher flow rate.
