INTERMITTENT PRESSURE HOLDING

Short motions. Long holds. Recharge on demand.

Our intermittent-holding solution combines a standard motor, PLC pressure feedback and an accumulator. After clamping, the accumulator supports pressure while the motor runs only when needed—especially suited to long holding phases.
  1. 01

    Build pressure

    A standard three-phase induction motor drives the pump to establish the pressure required for the motion.

  2. 02

    Hold with the motor stopped

    During the holding phase, the motor stops and an accumulator supports pressure holding.

  3. 03

    Recharge on demand

    A programmable logic controller (PLC) reads the pressure signal, restarts the motor below a set threshold and stops it at the set pressure.

APPLICATION SOLUTIONS

Start with your application.

01 / SOLUTION

CNC workholding

Reduce idle running after clamping while supporting the machining hold.

Explore the solution →

ENERGY INTO VALUE

Less idle running. More value.

Make each holding phase count. Stop the motor after motion, then recharge when pressure reaches the set threshold, reducing energy use and heat from continuous idle running.

Save 75% or more in short-motion, long-hold applications. Turn reduced electricity use into lower running costs and get more value from every clamping cycle.

Looking for a JDB hydraulic power unit?

If your existing equipment or paperwork refers to a JDB hydraulic power pack, send its nameplate and circuit drawing with your duty data. The current catalogue on this page covers SC-QT. An energy saving hydraulic power unit using intermittent pressure holding still needs project-specific checks; the new catalogue does not establish interchangeability with an older JDB unit.
