Dredge ball joints are designed to provide flexibility to the pipeline in all round direction up to a limited angle. To provide customer with the best suitable solution and lowest cost, Dredge Yard ball joints are designed in several types. That gives them variations in tilting angle from 15 to 18 degrees and duties from 10 bar to 30 bar.

All dredge ball joints are designed, produced, assembled, tested, painted, packed and transported under close supervision of Dredge Yard’s team of engineers and quality control. Dredge Yard uses strict ISO and ASTM standards for the design, production and testing of their dredge ball joints. The ball joints and material can be double tested at a third party for verification to ensure total customer satisfaction.

Dredge valve

Dredge Valves

The dredge valves are designed in three different working duties, varying between 10, 20 and 30 bar. Our dredge valve designs are entirely scrutinized due to using Finite Element Analysis. The dredge valve has an option of real time feedback for the position of the dredge valve gate.

Dredge Yard valves are designed, produced under strict ISO and ASTM standards and are double tested at a third party for verification. All dredge valves are designed, produced, assembled, tested, painted, greased, packed and transported under close super vision of the quality control team of Dredge Yard.

Dredge Yard emphasizes on after sales and ensures total customer satisfaction.

Dredge pump

Dredge Pumps

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

Dredge Yard 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.

Dredge Yard 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.

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

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
