Sanyang Heavy Machinery dredge pump is designed to be able to work in the harshest environments. The dredge pump system and mining pumps are suitable for pumping and handling all slurry, mud, sand, gravel, rocks and debris.

Sanyang is continuously working on optimizing the hydraulic design giving the dredge and mining pumps the highest efficiency, best wear performances, highest reliability and long duty life cycle.

Sanyang delivers bearing blocks designed to withstand all the forces acting from the dredge pump and impeller. The bearing block is designed and manufactured to.resist the vibrations, thermal vibration and shocks resulting from sudden impeller impacts and loads. The shaft, pedestal, bearings and bearing houses are made from first class material and suppliers to ensure the highest reliability and efficiency.

Dredge Pump System – FEATURES
The impeller has a double curved design
The pump impeller hub is machined to be fitted on the shaft, using a trapezoid thread
The impeller has double shrouds on both sides
Depending on the operation area, the pump impeller can be delivered with three, four or five vanes
The pump casting is type volute and single stage
Pump casing is provided with inserted thread to be bolt to pump plates
To allow a longer wear life, the pump casing is made from thick material
The discharge of the pump casting is provided with a discharge flange

Dredge Pump System – OPTIONS
The dredge and mining pump wear parts are delivered in different materials according to the project requirements and customers’ demands
Double walled execution to increase the wear time of the wear parts, as pressure on the pump casing is lower than single walled dredge pumps
High speed impellers for applications that run with direct drive
Gearbox mounted
The pump casing can be supplied with ribs to allow higher pressure ratings
Ladder or structure mounted for achieving the highest net positive suction head which makes dredging and mining for deep sea operations possible
