PUMP CURVE

A pump curve is a graphical representation of a pumps ability to produce flow against a certain head. The science is matching a curve that is accurate for your project, leading to the proper pump selection and best efficiency. EDDY Pumps are primarily used for high solids, slurry, sludge, and dewatering

The EDDY Pump Subdredge is a remote operated submersible dredge (ROV). The Subdredge is ideal for dredging applications that call for great depths, precision dredging, unmanned operation, and liner dredging application. A huge advantage is safety, making it ideal for dangerous situations where removing the human element from the operation is the goal.

It can be powered hydraulically or electrically with pump sizes ranging from 4-inch up to 12-inch. Achieve production rates of up to 7000 GPM or 600 cubic yards of material per hour. The Subdredge is equipped with an umbilical that allows for it to operate remotely at distances of up to 1000-ft from the operator. With internet connectivity, monitoring, troubleshooting, and operating, the unit can be conducted from the other side of the
globe by customer personnel or by EDDY Pump support staff.

Applications
