A hydrocyclone having a mid-section having a longitudinal axis and a radius, and a fluid injection member releasably connected to the mid-section. The fluid injection member has a dilution passage therethrough and two spaced apart dilution ports, at least one dilution port being at an angle between 15 and 75 degrees relative to the mid-section radius. The injection member comprises a nozzle housing releasably connected to the mid-section, the nozzle housing having a dilution passage therethrough, and a nozzle adapted to be connected to the nozzle housing, the nozzle being planar and having at least one dilution port therethrough, the nozzle being receivable within the dilution passage.

A reject chamber for use with a hydrocyclone for separating a fiber suspension into a heavy fraction substantially containing heavy contaminants and a light fiber fraction substantially containing fibers, the reject chamber having an internal cavity, a reject inlet into the internal cavity, and a reject outlet out of the internal cavity, the longitudinal axis of the reject outlet being angled relative to the longitudinal axis of the reject inlet. The reject chamber has a stem that extends into the internal cavity at the elbow of the reject chamber, and at least two bumps, each of which extend into the chamber on opposite sides of the stem, the reject chamber taken along a cross section through the stem and between the bumps having symmetrical sides.

A U-shaped cup seal comprises an inner wall, an outer wall spaced apart from the inner wall, a base connecting the inner wall and the outer wall, a first and having a tab, and a tab receiving second end.

Snap together u-shaped cup seal

An assembly with hydrocyclones comprising: multiple hydrocyclones having a inlet chamber with two side openings positioned on opposite sides of the inlet chamber and a overflow chamber having two side openings positioned on opposite sides of the overflow chamber. The hydrocyclones are arranged at a support structure, comprising a support bar for support of the hydrocyclones. The hydrocyclones being arranged side by side with their side openings adjacent each other thus forming an inlet pipe by means of the inlet chambers and an overflow pipe by means of the overflow chambers. The inlet chambers and the overflow chambers are adapted to be pressed against each other respectively. The hydrocyclones being arranged in pairs with one of the two hydrocyclones arranged on one side of the support bar and the other on the opposite sides thereof. A method assembling multiple hydrocyclones, wherein hydrocyclones are hung on a support bar at a base end or a head portion and are pressed together, is provided, and a support structure for an assembly of hydrocyclones, comprising a support bar, an end bar and one or two underflow pipes.
