Spin Klin Technology- Spin Klin Spine Model 2
General:
The Spin Klin discs are stacked on the Spin Klin spine.
The discs are color-coded by micron size, and are
assembled according to your water filtration requirements.
The spine assembly has a spring compression unit and an
internal piston which are used to alternately compress and
release the discs during filtration and backwash cycles.
Filtration Mode:
During the filtration process the filter discs are tightly
compressed together by the spring and the differential
pressure, forcing the water to flow through the grooves and
traps of the discs.
Backwash Mode:
During backwash the discs are released by releasing the inlet
hydraulic pressure. Multi-jet nozzles provide tangential spray
on the loosened discs, causing them to spin, and release the
retained solids, which are flushed out to the drain.
2” x 2” Backwash Valve
Filtration Position:
Water flows from port A (main supply) to port B (filter connection).
Port C (drain water outlet) is closed by the seal.
Backwash Position:
Command pressure is applied to the bottom side of the diaphragm
through port D.The diaphragm moves up, pulling the sealed body
by the shaft. Port A is closed by the seal, preventing flow to the
filter. Port C is now open allowing flushing water to flow from port B
(filter connection) to the drain.
