Sumitomo Demag DEMAG 2010 Training Manual

You are staring at a Sumitomo Demag injection press or a DEMAG crane that lost hydraulic pressure. Your aftermarket documentation shows generic symbols that don’t match the actual valve stack. You reach for the factory training manual. This Sumitomo Demag DEMAG 2010 Training Manual – 91 pages, published 2010 – is the original hydraulic theory and application guide used in the Sumitomo-Demag Technology Institute. It teaches hydraulic component function, circuit logic, and pressure control, not just part numbers.

Hydraulic Symbols and Circuit Diagrams

Chapter 1 covers the different hydraulic symbols used on DEMAG schematics. Switching valves, sequence valves, and pressure relief valves – each symbol is drawn with its exact port designation and flow path. If you cannot read a hydraulic schematic, you will misroute lines and over-pressurize components. The manual uses German standard symbols with cross-references to Sumitomo Demag machine prints. Page 5 breaks down every symbol family.

Shut-Off Valves (Check Valves): Operation and Application

Chapter 3 goes into shut-off valves – check valves, pilot-operated check valves, and electrically unlocked double check valves. It explains the internal seat geometry and cracking pressure behavior. A stuck check valve on a DEMAG clamp cylinder will cause slow cycling or creep. The manual shows the internal cross-section and how to test pilot pressure without disassembly.

Pressure Valves: Standard vs. Proportional

Pressure control valves get their own chapter (Chapter 5). Standard pressure relief valves, proportional pressure relief valves, and pressure reducing valves. Each has a circuit diagram, a functional description, and the adjustment range. The manual differentiates between direct-acting and pilot-operated relief valves. Proportional valves require a specific PWM driver – this manual explains how to measure the control current without frying the coil.

Throttles and Flow Control

Throttle valves and flow regulators appear in Chapter 4. The manual details orifice geometry and how viscosity changes affect flow rate. If you are chasing a slow-moving axis on a Sumitomo Demag machine, check the throttle setting against the factory spec. The training manual gives the design criteria, not just a curve. You can calculate the required orifice diameter for a given cylinder speed – something aftermarket guides skip.

Servo Valves and Seat Valves

Chapter 7 covers servo valves – the full cross-section, spool position, and pilot stage. Chapter 8 deals with seat valves, including their logic element and switching characteristics. Servo valves on DEMAG equipment control injection velocity and pressure. If you swap a servo valve without understanding the null adjustment, you create instability. This manual includes the bench test procedure and what to check before installation.

Who Needs This Manual

If you own a Sumitomo Demag injection molding machine or a DEMAG mobile crane, this is your hydraulic foundation. DIY mechanics and small shop owners who maintain these machines will save hours by understanding which valve does what. The manual is written in Russian, but the diagrams are universal – any tech who reads schematics can follow the functional descriptions. Pair it with the Sumitomo Demag SH160 2005 Service Manual – OEM Factory Specs”>SH160 service manual for repair procedures, or get the SUMITOMO Consumables Parts Listing for Equipment Models”>consumables parts listing to cross-reference seal kits.

Source Authenticity: OEM Training, Not Aftermarket

AutoRepairManuals carries the original Sumitomo-Demag Technology Institute document. This is not a third-party compilation – it is the same binder used in the factory training courses. Aftermarket hydraulic manuals genericize the symbols and omit proportional valve tuning. This manual includes the exact chapter numbering from the Sumitomo-Demag curriculum: Гидравлика, Переключающие клапаны, Напорные клапаны. If you want to understand why a DEMAG machine behaves the way it does, start here.

3 Reasons to Choose OEM Documentation

• Factory pressure and flow parameters – not estimated values
• Component cross-sections that show seal locations and pilot passages
• Circuit logic that matches actual machine wiring and plumbing

Contrast that with a generic manual that shows a check valve symbol but no internal spring rate. You cannot tune a proportional relief valve with a vague diagram.

Is this manual available in English?

No. The document is in Russian. However, the hydraulic symbols and diagrams are language-independent. The technical density is high – you do not need fluent Russian to follow the circuits. If you cannot read Cyrillic, the schematics alone are worth the access.

Does it cover specific Sumitomo Demag model numbers?

The manual is a general hydraulic training document for the DEMAG series. It does not list individual model numbers like SH160 or SGA10. For model-specific torque values and wiring, pair it with the corresponding Hyundai Kia Transaxle Training Manual”>Hyundai Kia transaxle training manual if you are dealing with a hybrid drivetrain – no, wrong context. For Sumitomo Demag, use the OEM service manual for your machine. This training manual teaches the theory behind the components you will find on every DEMAG platform.

What tools do I need to use this manual effectively?

A basic understanding of hydraulic symbols and a pressure gauge. The manual references a manometer (page 8). For testing, you need a flow meter and a digital multimeter to measure proportional valve coil resistance. No special tools required – just the willingness to read schematics.

Can I use this manual for other brands like Bosch Rexroth or Parker?

The principles apply, but the circuit logic and valve layouts are specific to Sumitomo Demag machines. If you are working on a different brand, you will find the same hydraulic laws, but the symbols and port numbering differ. Stick to the manufacturer-specific documentation for that equipment. This manual is for DEMAG systems.

Access the Factory Manual. It gives you the same hydraulic training that Sumitomo Demag techs receive. Whether you are troubleshooting a stuck check valve or tuning a proportional pressure control, this 91-page document is the foundation. Pair it with a Manual Transmission”>manual transmission guide? Not needed – but if you are also maintaining a vehicle, keep the transaxle training manual handy. For the hydraulic side, this is your single source.
