Let KREBS® DeSanders solve your fine particle separation problems

How they work

DeSanders, also known as separators, work similarly to cyclones.

Fluid with suspended sand or grit feeds into the unit. Our entry design creates a vortex action for the slurry. As the liquid spirals inward, extremely high centrifugal forces move the sand outward, toward the cylinder wall. All desanding units have an internal cone section that accelerates the rotational velocity of the water to produce higher centrifugal forces. As the diameter of the cone gets smaller, the acceleration increases which results in a finer separation and removes more solids. Sand particles progress in a spiral path toward the apex (bottom) of the cone, where they discharge into an accumulator tank that collects the solids. The liquid exits the separator from the overflow at the top.

Our DeSanders are simple to operate because they have no moving parts. They provide efficient separation with relatively low power consumption.

Simple and effective separation

Our DeSanders are compact, reducing capital and installations costs. They are simple to operate, with no moving parts. And they provide efficient separation with relatively low power consumption.

Wear resistant

Depending on your application, we offer units that are unlined, lined with vulcanised gum rubber or lined with replaceable gum rubber liners. We recommend units with replaceable liners in abrasive applications. For non-abrasive applications, we recommend units with vulcanised lining or no lining at all.

Versatile and customisable

All of our desanding units may be mounted horizontally, vertically or at an angle in between. They are available in different sizes with different internal fittings to fully optimise your performance. Using computer simulation, we are able to accurately predict your DeSander’s performance to determine the ideal DeSander units for your application and eliminate the need for onsite testing.

Size and performance

Our KCSS, KD and KS DeSanders come in a wide range of sizes, from 51–1270 mm (2–50 in) in diameter, as measured at the cylinder section. Different internal fittings optimise your unit’s performance for your unique application. All models are flanged for inspection and wear parts replacement.

* Units come in unlined only

Mounting

Our DeSander units can mount and operate efficiently at any angle, including fully horizontal or vertical positions. The horizontal units are relatively low to the ground and easy to conceal, a popular option for residential neighborhoods.

Piping and connections

The water outlet may be positioned either at the centre of the top of the unit or tangentially. We also design units for clockwise or counterclockwise rotation to make installation easy regardless of your piping configuration.

Materials of construction and lining

We use carbon steel as our standard material of construction. But our DeSanders may be built to any specification and from any alloy to meet your requirements, including units built to ASME code section VIII, division I specifications. We offer our units unlined, lined with vulcanized gum rubber or lined with replaceable gum rubber or ceramic. Regardless of your application, budget constraints and preferences for wear life, we have you covered.
