    Allows for permanent spray nozzle mounting to the die. Ensures nozzles remain in correct position with each die change.

    Fluid Supply Systems
    Fluid Supply Systems
    Your fluid application system needs a steady supply of pressurized fluid. Unist offers a broad range of options to meet your needs.

    powered uni-roller
    Programmable fluid controller

    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® S2, TSL System, Mini-Roller, Powered Uni-Roller® and/or Low Volume Spray Nozzles.

    Patent No. 6567710*

    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 Applications:

    Provides programmable control for the following applications/Unist systems:

    • Punching (Mini-Roller, Uni-Roller® S2)
    • Stamping (Mini-Roller, Uni-Roller® S2, Uni-Roller S2 Powered®, TSL System, Low Volume Spray Nozzle)
    • Fine blanking (Uni-Roller® S2, Uni-Roller® S2 Powered)
    • Deep Drawing (Uni-Roller® S2, Uni-Roller® S2 Powered)
    • Application of rust preventives & protective coatings (Low Volume Spray Nozzle, Uni-Roller® S2)
    • 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.
