Introduction:
Pump Model: SG/150E
The SG range of dredge and gravel pumps is designed to provide continuous pumping of highly abrasive slurries containing large particles at high maintained efficiencies with low maintenance and ownership costs. The impeller fitted to our SG heavy duty gravel pumps is the closed type with three vanes, which allow the impeller to pass large rocks. The heavy-duty dredge pump is specifically designed for low head duties such as hopper dredging and barge loading.
The dredge pump is one of the main components of the dredger, and it is critical for achieving production. Dredge pumps also have the biggest power consumption during operation so efforts to reduce the pump’s power needs through smarter design are critical.
Features of Sand Dredging Pumps:
Enhanced Performance; Enhanced Efficiencies; Enhanced Abrasion Resistance
Longer casing life- The large volume of the casing reduces internal velocities resulting in reduced wear;
Lost production time is reduced and screening is avoided- Because the internal proportions of the Dredge and Gravel pump ranges allow extraordinary large particles to be passed.
Long component life with no need for wear rings- The special shape of the impeller vanes and casing combine with side sealing vanes to reduce recirculation down the front of the impeller and exclude abrasive solids from between the impeller and casing.
Reduced leakage and wear- Side sealing vanes on the shaft side of the impeller reduce gland pressure and intrusion of solids into the gland area.
