Permanent Removal
When permanently removing cones from the desilter, first eliminate positions closest to the
discharge pipe and then extend outward from those positions, as necessary. To maintain balance,
remove cones in pairs directly across the discharge pipe from each other (one from each side of
the discharge pipe). For example, if cone "A" is removed, also remove cone "K" (Figure 5-5). If the
desilter has a full complement of cones, the following removal sequence is suggested when
removing cones:
A & K, J & T, B & L, I & S, C & M, H & R, etc.
Installation
WARNING! WHEN INSTALLING CONE ON AN OPERATING DESILTER, BE
SURE THAT SHUTOFF VALVE IS CLOSED BEFORE RELEASING SNAP
COUPLINGS SECURING VICTAULIC
WARNING! ALWAYS WEAR SAFETY GLASSES WHEN INSTALLING
HYDROCYCLONES IN A PRESSURIZED DESILTER.

1. If Victaulic caps (Derrick part number VIC-2-60) were installed on manifold ports, release
snap couplings and remove caps.
2. Slide snap coupling gasket on end of manifold pipe.
3. Align inlet pipe of hydrocyclone with manifold pipe, and center gasket between the snap
coupling grooves in hydrocyclone and manifold pipe (Figure 5-6).
4. Install Victaulic snap coupling so that coupling engages grooves in manifold pipe and
hydrocyclone.
5. Engage and close locking handle of snap coupling to secure manifold pipe and hydrocyclone.
6. Repeat steps 1 through 5 for remaining hydrocyclone-to-manifold connections.
