Automation · Special-purpose machines
Multi-actuator hydraulic power units for special-purpose machines and automation cells. One power unit drives every clamp, slide, ejector and index motion in the cycle — with manifold-based control and valve sequencing so each actuator fires in the right order, at the right pressure, on your PLC's command.
What it is
A special-purpose machine rarely needs just one hydraulic motion. A typical cell might clamp a part, advance a slide, drill or press, then eject — several actuators, each with its own force, speed and timing. An SPM hydraulic power unit supplies all of them from a single reservoir and pump set, and coordinates them through a valve manifold rather than a rack of loose plumbing.
We build the unit around what your machine actually does. Pressure and flow are sized to the actuators and the cycle time; the pump and motor are chosen for the duty; and the manifold carries the directional, pressure and flow-control valves that sequence the motions. Solenoid valves are wired for PLC control, so your automation commands each step and pressure or limit feedback confirms it before the next begins. The result is a compact, leak-checked power unit that behaves as one integrated part of the cell.
Because every SPM is different, nothing here is a fixed catalogue item — the build is defined by your actuator schedule, cycle diagram and electrical interface, then confirmed by a Suyog engineer before quoting.
Reference configurations
Indicative build envelopes to help you shortlist. All figures are typical / illustrative — not a fixed specification or price list. Your unit is sized to its actuators and cycle by a Suyog engineer.
| Parameter | Compact cell | Multi-station SPM | Heavy / high-flow SPM |
|---|---|---|---|
| Working pressure | up to ~140 bar | up to ~210 bar | up to ~650 bar |
| Flow rate | ~5–15 LPM | ~15–60 LPM | up to ~200 LPM |
| Actuator stations | 2–3 | 4–8 | Multi-station |
| Control | Solenoid manifold | Manifold + sequencing, PLC-ready | Manifold + proportional, PLC-ready |
| Motor | 2–3 HP (typ.) | 3–10 HP (typ.) | To duty |
| Tank | ~35–50 L | ~63–150 L | To heat load |
Typical — confirmed on enquiry. The above are indicative reference envelopes, not a final specification or price list. Actuator count, pressure, flow, sequencing, motor, tank and cooling are matched to your machine cycle and confirmed by a Suyog engineer before quoting.

Engineered to specification
Every element of an SPM power unit is chosen for the cell it serves:
In-house testing
No SPM power unit leaves our factory untested. Each applicable unit is run on our own bench up to 650 bar / 200 LPM — pressure, flow, valve sequencing and functional operation are checked, and a pre-dispatch test certificate is issued.
Warranty & documentation. Every SPM hydraulic power unit is supplied with a standard manufacturer's warranty against manufacturing defects — terms confirmed in writing at order. A detailed technical datasheet, hydraulic circuit diagram and test certificate for your specific build are available on request once the configuration is fixed.
Questions
A single power unit can drive several actuators — clamps, slides, ejectors and index drives — from one reservoir and pump set. The number of stations depends on the cycle: simultaneous motions need enough flow to feed them together, while sequenced motions can share flow. We map every actuator and its cycle timing before fixing the pump, motor and manifold.
Yes. Sequencing is handled on a manifold using directional, pressure and flow-control valves, with solenoid valves wired for PLC control. We provide the circuit and interface so your PLC commands each motion, and pressure or limit signals confirm each step before the next begins.
Yes. An SPM power unit is engineered to the machine, not picked from a shelf. We size pressure and flow to the actuators and cycle time, choose the pump and motor for the duty, and lay out the manifold, tank and controls to fit the cell and its electrical interface.
Yes. Every applicable unit is run on our in-house bench up to 650 bar and 200 LPM, with pressure, flow, valve sequencing and functional operation verified, and it ships with a pre-dispatch test certificate.
