All parts, susceptible to wear, are manufactured from high-chrome alloy of the best quality or an excellent Nihard IV quality with a hardness of 550 HB. The motorization and coupling installation to use this pump is a responsibility of the customer who acquires it, paying attention to the operating performance information (RPM, Flow and Total Head Heights) to ensure proper operation of the assembly.(Capacity range from 500 up to 10.000 m3/hr)ĭe Hollandsche Yssel double walled dredge pumps are of modern design and made of the best quality wear-resistant material.

The parts that make up this dredger pump and are assembled together are: 1- Carcass or Snail 2- Impeller 3- Flange Tighten Gasket 4- Trestle Protection for Discs and Impeller 5- Shaft 6- Bearings 7- Trestle / Easel 8- Sealing Rings 9- Gasket 10- Screws / Nuts / Lock Washers. Our pumps are not self priming, so it should be primed throughout the drive. The equipment has versions with fixed nozzles, where the hoses are coupled directly to the housing nozzle and versions with movable screw nozzles, where the hoses are coupled to a nozzle that is later screwed into the pump inlet or outlet. Weight may vary by model purchased and alloy chosen. Nickel (black) metal alloys are indicated for the movement of various materials but with greater resistance to sand and sedimentary residues that promote abrasion.Īpproximate Weight: 3 'Pump - 73kg / 4' Pump - 76kg / 5½ 'Pump - 140kg / 6½' Pump - 184kg / 8 '- 240kg Pump. Steel (green) alloys are indicated for the movement of various materials but with greater resistance to stones, pebble and small gravel that promote impact. Iron (yellow) alloys are indicated for moving sludge, organic sediments, mud, gravel and sand in low concentration.

It supports 70% liquid to 30% solids handling during its operation.Įquipment available in different metal alloys (Carcass or Snail) for better adaptation to the material to be dredged. Pump often used for irrigation, fish farming, animal waste drainage, sludge / mud / sand transportation for industry and mining applications. Sturdy metal alloy, product with Brazmix quality assurance.Īpplication: Suitable for the most diverse liquid and solid handling purposes in short, medium and long distances.
