Spin Klin Apollo Automatic Filter Batteries

Automatic disc batteries Arkal Spin Klin Apollo provide uninterrupted industrial water filtration with automatic backwashing. The central Spin Klin spine releases disc compression while tangential water nozzles rapidly spin the rings to flush all captured solids.

Ultra-short automatic backwash cycle per pod requiring only 20 to 25 seconds
Uninterrupted downstream supply maintained during backwash of adjacent modules
Modular scalable battery layout engineered to expand overall filtration volume
Electronic controller sequencing automated cleaning by time and pressure drop

Polymer Diaphragms for PLASLITE-DIAPHRAGM SK Valves

Replacement diaphragms PLASLITE-DIAPHRAGM SK (part number 730113-000263) are engineered for 3-way hydraulic backwash valves in Spin Klin filter installations. The elastomer diaphragm provides prompt shifting between filtration and drain modes during backwashing.

Exact dimensional compliance with Dorot 58P and Bermad hydraulic valve bodies
Resilient chemical-grade elastomer built for millions of actuation sequences
Positive internal port sealing during dynamic hydraulic switching transitions
Standard part 730113-000263 for scheduled refurbishment of flushing valves

Replacement Disc Rings and Spine Assemblies Arkal

Standardized replacement disc rings and internal spine assemblies Arkal restore hydraulic throughput of Netafim filtration equipment. Rings are manufactured from high-grade grooved polypropylene, creating a 3D depth matrix for trapping microscopic debris.

Standard color coding: black 100 microns, red 130 microns, yellow 200 microns
Tight mechanical disc compression driven by spring assembly during filtration
Resilient to regular chemical restoration using diluted acid or chlorine wash
Convenient cartridge replacement without unbolting mainline pipe connections

Depth Disc Filtration Mechanics and Spin Klin Principles

Arkal disc filtration technology relies on an array of grooved polypropylene rings engineered with microscopic diagonal channels across both faces. When compressed on a central spine, opposite groove patterns intersect to form a three-dimensional depth matrix featuring millions of particle traps.

Unlike traditional screen strainers that capture solids purely on an exterior plane, disc units retain heavy mineral grit and cohesive organic suspensions throughout the entire depth of the stack.

During automated backwash sequences, hydraulic pistons release ring compression while tangential water nozzles spin the discs freely, expelling all trapped debris through the drainage manifold without manual intervention.

Automated Spin Klin Apollo Batteries and Backwash Sequencing

Modular Spin Klin Apollo battery installations integrate multiple filtration pods into a parallel process manifold governed by an electronic controller. Under standard filtration modes, process water enters through the common inlet header and undergoes concurrent treatment across all active modules.

When differential pressure thresholds are reached or preset timers expire, the control unit cycles pods individually through automated backwashing. Flushing a single pod requires merely 20 to 25 seconds and utilizes clean filtrate supplied by operating companion units.

This design prevents downtime across the facility and maintains uninterrupted delivery of clean water to downstream operations.

Engineering Design of 4" Super Leader Mainline Filters

Heavy-duty Arkal 4" Super Leader filters are developed for intake headers and high-throughput circulation loops across industrial sites, delivering volumetric flow rates up to 100 m3/h per pod.

The outer body is molded from high-strength fiberglass-reinforced polyamide resilient against dynamic water hammer and aggressive solutions. The filter hood incorporates an internal telescopic extension holding the ring assembly when decompressed, simplifying visual inspection.

Flange interfaces utilize standardized ARKAL Universal Flanges matching DIN, BSTD, and ANSI bolting dimensions, enabling straightforward integration into existing pipeline layouts.

Angular Configuration of Arkal 4" Angle Units and Micron Selection

Compact Arkal 4" Angle filter housings are optimized for tight plant rooms and skid-mounted water treatment assemblies handling throughput volumes up to 90 m3/h. The 90-degree angular fluid geometry reduces unnecessary elbows and minimizes localized piping friction.

Replacement disc elements feature standardized color-coded micron grades: grey 20 microns, green 55 microns, black 100 microns, red 130 microns, yellow 200 microns, and blue 400 microns.

Accurate micron selection shields reverse osmosis membranes, cooling tower spray nozzles, and heat exchanger bundles from abrasive mechanical wear and blockage.

Hydraulic Actuation Diaphragms for PLASLITE Dorot and Bermad Valves

Automated Spin Klin filter batteries rely on 3-way hydraulic backwash valves engineered by Dorot 58P and Bermad utilizing PLASLITE polymer diaphragms.

Upon receiving a pilot hydraulic signal from the solenoid, the PLASLITE-DIAPHRAGM SK (part number 730113-000263) shifts immediately, shutting the supply seat and opening the flush drainage path.

Diaphragm wear or elastomeric fatigue leads to continuous drainage loss and pressure drop across the distribution header. Routine installation of fresh polymer diaphragms restores positive port isolation and eliminates leakage of untreated liquid into the clean stream.

Preventive Maintenance Routines, Chemical Cleaning, and Disc Inspection

Scheduled maintenance of Arkal Netafim disc filtration equipment includes monitoring differential pressure gauges, inspecting elastomeric seals, and periodic examination of disc stacks.

When stubborn mineral scale or biological slime accumulates, rings are removed from the spine, strung loosely onto a service cord, and immersed in a 5% hydrochloric acid or sodium hypochlorite bath.

Following neutralization and clean rinsing, rings are reassembled onto the spine, ensuring tight compression beneath the retaining nut. Timely replacement of internal spine seals and diaphragms preserves designed throughput and ensures dependable filtration.
