Hydrocyclone Sand Separator for Irrigation Wells

Separate heavy particles near the source

A hydrocyclone sand separator uses the motion of water through a conical chamber to separate particles heavier than water into a collection area. It can be useful ahead of fine filtration where irrigation wells carry sand. The red separator shown has a lower collection chamber and support frame; it is a sand-separation stage rather than a complete treatment system for every contaminant.

Select by flow as well as connection size

The listed choices are 2-inch, 3-inch and 4-inch connections with a 10-bar pressure designation. Confirm the actual port dimensions and connection standard before selecting mating pipework. The appropriate size depends on the operating flow through the separator, not simply the diameter of the existing supply. Obtain the minimum and maximum flow and pressure-loss information for the selected size.

Keep a fine filter downstream

Centrifugal separation does not establish removal of algae, dissolved material or all light suspended solids. Use a downstream screen or disc filter selected for the emitters and water quality. A plastic separator or another steel separator with a similar cone can have a different flow range and collection arrangement; its ratings cannot be used to size this unit.

Provide room for sediment removal

Plan a supported installation with access to the lower collection chamber and its drain. Follow the marked flow direction and keep pipe loads off the vessel connections. Check joints during commissioning and establish a sediment-removal routine from the observed sand load. Before opening a chamber or removing a closure, isolate and depressurize the assembly. Monitor pressure loss and downstream filter condition during operation to judge whether the filtration train needs servicing or a change in capacity.
