Arkal Spin-Klin 3” Battery – User Manual

This Arkal 3” Spin Klin battery is an automatic self-cleaning filter designed for non-hazardous liquids only

and within the pressure and temperature framework described in the specifications table.

Operation

During the filtration stage, water flows through the INLET manifold and is distributed through the 3” x 2” back-flush
valves into the Spin Klin filters. The water then passes through the filter elements to the outlet manifold for consumer
use.

Description of the Back-Flushing Process

1. The controller transmits an electrical command to the first solenoid per either differential pressure or time.

2. The solenoid then sends a pressure command to the back-flush valve, moving it from the filtration mode to the

back-flushing mode.

3. Filter #1 is then back-flushed with water from the outlet manifold that has been filtered by the other filters in the

system. Contaminated water and impurities flow out through the drain manifold.

4. On completion of the allotted back-flush time the controller releases the back-flush command. Filter #1 return to

the filtration mode.

5. Filter #2 then enters the back-flush mode, and the process is repeated until all the filters in the system have been

back-flushed.

6. After all the filters have been back-flushed the system returns to the filtration mode, until the next back-flush

cycle.

Spin Klin Technology - Spin Klin Spine

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 back-flush 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.

Back-flush Mode:

During back-flush 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.

3” x 2” Back-flush 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.

Back-flush Position:

Command pressure is applied to the top side of the diaphragm through port [D]. The diaphragm moves down, pushing
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.
