Calculators
How do I size the spec?
Code computes directly from engineering formulas (no estimation). Results link to the matching product line.
Pump flow Q = V·n / 1000
Pump (inverse) V = Q·1000 / n
Motor torque T = V·ΔP / 20π
Motor (inverse) V = T·20π / ΔP
Cylinder force F = P·πD²/4
Cylinder (inverse) D = √(4F / πP)
Cooler heat rejection Φ = Q·ΔP·(1-η) / 600
Electric motor power P = Q·ΔP / (600·η)
8 engineering formulas. Results link to the matching product line. Each calculator is also available as a standalone page. Exact models and stock are confirmed by quotation.
Control Systems
Do you also develop control systems?
Beyond parts supply, our in-house controls team takes mobile-machinery electronic control systems from design through development, verification and production.
Development process
- 01Requirements analysis — define machine operating scenarios, safety requirements, operating environment
- 02System design — select controllers, valves, sensors, HMI; design CAN (J1939) architecture
- 03Control SW development — application development based on CODESYS, PLUS+1 GUIDE, C
- 04Bench verification — load, endurance and fault-condition tests on our own hydraulic test bench
- 05On-machine calibration — tuning valve deadband, ramps and gains on field machines
- 06Production & after-support — diagnostic tools, parts supply, firmware maintenance
Development platforms: Bosch Rexroth BODAS RC · TTControl HY-TTC · Danfoss PLUS+1 · CODESYS — we build and maintain our own controller spec database of 26 models

Troubleshooting · fundamentals · industry trends. AI-drafted, human-reviewed. Full articles are in Korean.
Troubleshooting · NEWWhen a hydraulic motor lacks power — a 7-step field checklist (Korean)▾
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.
Controls · NEWMobile controller selection guide — BODAS RC vs HY-TTC vs PLUS+1 (Korean)▾
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.
TroubleshootingWhy does hydraulic pump cavitation happen and how do you fix it? (Korean)▾
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.
FundamentalsWhat are the basic components of a hydraulic circuit? (Korean)▾
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.
TrendsHow do hydraulic systems change in the age of electrification? (Korean)▾
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.

FAQ
Frequently asked questions
The most common questions from real inquiries. For case-specific checks, use contact.
What is the lead time?▾
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.
What information do you need for a quotation?▾
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.).
Do you supply explosion-proof products?▾
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.
Can you propose replacements for discontinued or other-brand products?▾
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.
Do you support repairs, after-sales service or spare parts such as seal kits?▾
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.
How does a control system development project proceed?▾
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.
