Programmable fluid controller

  • powered uni-roller

    Patent No. 6567710*

  • The SPR-2000 programmable fluid controller* Controls with electronic precision and consistency how much fluid flows to one or more of these Unist systems: Uni-Roller® Type S, TSL System, Mini-Roller, Powered Uni-Roller® and/or Low Volume Spray Nozzles.

The automatic lubrication system intermittently actuates a bank of fluid Solenoid Valves (up to 22 outputs) that dispense a programmed quantity of fluid to specific lube points. The valve actuation on this electronic fluid dispenser is determined by production line rates so there is no under or over lubrication whether it is a stamping press or roll forming operation.


  • Benefits of Automatic Lubrication Systems

    • Monitors critical parameters
    • Precision fluid control
    • Controls up to 22 outputs
    • Stores up to 250 different setups/jobs
    • Access code prevents tampering
    • Saves fluid: precisely controls fluid
  • Typical SPR-2000 / Uni-Roller® application


save 50 percent

Combine the SPR-2000 with a Uni-Roller® applicator to reduce fluid usage and save money

On average, a Unist automatic lubrication system can reduce stamping fluid consumption by 50% with some customers reporting reductions as high as 90%!

Full-featured monitoring

  • The SPR-2000 provides full-featured monitoring of critical parameters such as fluid level, pressure and flow (optional sensors are required) and alerts users with an audible alarm and red LED. An external alarm relay can also be wired directly to a press control on this electronic fluid dispenser.

Easy set up with intuitive menus


  • Access code menu

    Provides password-protected access to the system's setting.

  • Auto setup menu

    prompts the user for job specifications and automatically creates a new setup (program) for Uni-Roller® applications.

  • Edit menu

    allows the user to modify current setups and program spray nozzles or otehr auxillary functions.

  • Alarm menu

    allows the user to monitor critical system functions.

SPR-2000 Electronic Fluid Dispenser Applications:

Provides programmable control for the following applications/Unist systems:

    • Punching (Mini-Roller, Uni-Roller® Type S, Uni-Roller® Type C )
    • Stamping (Mini-Roller, Uni-Roller® Type S, Uni-Roller® Type C, Powered Uni-Roller®, TSL System, Low Volume Spray Nozzle)
    • Fine blanking (Uni-Roller® Type S, Uni-Roller® Type C, Powered Uni-Roller®)
    • Deep Drawing (Uni-Roller® Type S, Uni-Roller® Type C, Powered Uni-Roller®)
    • Application of rust preventives & protective coatings (Low Volume Spray Nozzle, Uni-Roller® Type S, Uni-Roller® Type C)
    • Fin Stamping (TSL System)
    • Cupping / Canmaking (Coil Lubrication System, Sheet Lubrication System, Tab Stock Lubrication System)

Delivers return on investment in less than 6 months

That's what many of our customers report. By applying the proper amount of fluid, the combination of an SPR-2000 controller and Uni-Roller® lubricator uses 50 to 90% less lubricant. Plus it decreases the mess, the parts cleaning, fluid recycling and costs associated with in-die spray systems, rag technology and externally lubricated rollers.

SPR-2000 options
