Summary: "No power" splits into low torque (pressure side) and low speed (flow side). Checking in order — relief setting → pump outlet pressure/flow → motor case drain → fluid viscosity/contamination → line losses → counterbalance valve → motor wear — narrows the cause quickly.
Key pass/fail criteria — case drain flow above 10% of rated suggests internal motor wear; pump flow 15–20% below rated suggests pump wear.
Summary: Controller selection comes down to five factors: I/O count (20–30% headroom), safety level (PL/SIL), development environment (C, CODESYS, GUIDE), CAN channel count and supply stability. We compared representative BODAS RC, HY-TTC and PLUS+1 models against our own controller spec database.
Rough direction — HY-TTC 32 class for small utility machines; BODAS RC 40 series or HY-TTC 508 class for PL d work functions; PLUS+1 when the design centers on Danfoss hydraulics.
Summary: Cavitation occurs when suction-side pressure falls below the fluid's vapor pressure — bubbles form and then collapse under discharge-side high pressure. It causes noise, vibration, metal erosion and efficiency loss.
Main causes — ① clogged suction filter/strainer ② undersized or overlong suction piping ③ excessive fluid viscosity (cold) ④ low tank oil level ⑤ pump overspeed.
Fixes — inspect/replace the suction filter, size the suction line properly (suction vacuum ≤ 0.2 bar recommended), correct-viscosity fluid and pre-heating, adequate oil level, respect rated speed. Consider a boost pump or pressurized tank.
Summary: A hydraulic circuit has four building blocks: power source (pump), control (valves), actuators (cylinders/motors) and auxiliaries (tank, filter, cooler). Flow produced by the pump is directed, pressure- and flow-controlled by valves and converted to work at the actuator.
Key relationship — flow Q determines speed; pressure P determines force/torque. Motor torque T = V·ΔP/20π, pump flow Q = V·n/1000 (see the calculators on this page).
Design order — actuator requirements (force, speed) → required pressure & flow → pump/valve selection → heat rejection (cooler) & filtration design. Use our engineering tools for a first-pass sizing, then match to partner products.
Summary: With electrification of construction and special-purpose machinery, engine-driven hydraulics are moving to electric-motor + hydraulic hybrids. Hydraulics remain essential where power density matters, and integration with electronic control (sensors, HMI) is accelerating.
Changes — ① on-demand electric pumps (run only when needed, saving energy) ② electro-proportional valves with closed-loop sensor feedback ③ CAN-based integrated control and diagnostics.
Implication — combined hydraulics+control spec design matters more than single-part supply. WOORI Enterprise matches M+S/Walvoil hydraulics with CrossControl/Gefran control in one place.

Stocked items (2,500+ SKUs) can ship immediately after confirmation. Lead times for overseas orders vary by brand and item — send the part number and quantity and we will confirm stock and delivery right away.
Fastest: the part number (model) or a nameplate photo of the currently installed unit, quantity, and desired delivery date. If you do not know the part number, we help select one from the target machine and required specs (pressure, flow, voltage, etc.).
Yes. We have supplied explosion-proof radio and wired remote controls such as ARCON. Please include the required certification standard (area classification) with your inquiry.
Yes. Send drawings, specifications or a nameplate photo and we will review dimensional, port and spec compatibility and propose a replacement model from the brands we carry.
Availability of spare parts (e.g. seal kits) and repair support varies by brand. Give us the target part number and the symptom and we will confirm what support is possible.
Requirements analysis → system design → control SW development (CODESYS, PLUS+1) → bench verification → on-machine calibration → production support. See the Control Systems section for the full process.
