01 / FILTRATION · SFVP

Circulation filter pump

Continuous circulation keeps the bath clean.

Used for bath circulation in high-temperature electroless nickel operations, filtering foreign matter, dust and other impurities to help maintain bath cleanliness and plating quality.

  • Circulation and filtration at the same timeImpurities are continuously removed while the bath circulates.
  • Observable without disassemblyCheck filtration status through the transparent filter housing for easy operation and maintenance.
  • Dedicated anti-deposition structureDesigned for electroless nickel processes, with a dedicated structure to suppress plating deposition.
  • Stainless steel constructionEquipment listed in the product catalog uses all-stainless-steel construction with a special dry seal.
Select by bath size

Standard data lists four models, SFVP-I to SFVP-IV, covering tank capacities of 100–3,000 L. Confirm the final configuration with circulation needs, filtration accuracy and on-site piping.

02 / ANALYSIS & REPLENISHMENT · SACP

Automatic analysis & compensation unit

Linking bath condition with replenishment management.

Manages, controls and automatically replenishes based on bath concentration, pH and temperature, supporting bath condition management during production.

  • Flowmeter compensationReplenishment controlled by flowmeters.
  • Operating records keptSupports printing and recording of operating data, alarm data and setpoints.
  • Expandable on demandOptional automatic pH correction and data transfer to an indoor computer.
Option notes

Automatic pH correction and computer data transfer are optional functions that must be specified in the equipment plan. The real-scene photo shows on-site installation; specific processes and configuration are confirmed per project.

03 / AUTOMATION

Automatic make-up & nitric acid passivation system

From tank preparation to make-up and heating, linking each operation step.

Automatic valves and a control system bring tank nitric acid passivation, make-up and bath heating under automated management, reducing manual valve operation. With on-site IoT applications, operating status can be visualized to reduce human error.

System configuration

Control logic is arranged by plating tank, nitric acid tank, spare tank and on-site piping, with the scope of automation confirmed against the production rhythm.

01Nitric acid passivation

Completes tank passivation in preparation for subsequent operations.

02Automatic make-up

Linked to the make-up step by automatic control.

03Bath heating

Bath heating is prepared before operation.

TANKS & AUXILIARIES

Tanks and auxiliary equipment working together

The plating tank performs plating; the nitric acid tank serves tank passivation; the spare tank temporarily holds the bath during cleaning and passivation.
