Page 12: Introduction
1. For Safe Operation 1.1 Hazards peculiar to the pump and safety measures Before operating or inspecting the pump, read this section carefully to fully understand potential hazards and prevention methods. The pump is not to be used with toxic of flammable gases. 1.1.1 Danger Leakage of hazardous gases and substances Cause... -
Page 13: Warning Explosion
1.1.3 Warning Explosion Cause Prevention method and measures ⇒ The maximum internal pump pressure is 0.03 MPa (gauge The pressure in the pump increased causing the pump pressure). to explode. Measure the pressure at the outlet side and, if the pressure is 0.03 MPa or more (gauge pressure), remove objects which block the passage of gas from the outlet side. -
Page 14: Outline Of The Pump
This oil sealed rotary vacuum pump is a rotary vane pump (hereinafter called Gaede type pump) in which the pump is directly driven by the motor. Since the pump is small, light, and quite simply constructed, it is easily maintained and repaired. Table 1 Specification GLD-040 Model Unit 50 Hz... -

Page 16: Installation
3. Installation 3.1 Installation The pump should be installed on a level surface in a location with minimal dust, dirt and humidity and be arranged with consideration given to ease of installation, removal, inspection and cleaning. Particular attention should be paid to the ambient temperature when building the pump into equipment. -
Page 17: Lubrication
3.2 Lubrication Remove the oil inlet plug from the oil inlet port, and add the pump oil which has been delivered together with the pump or the pump oil specified by us (R-2) up to the range marked with the line on the oil level gauge. -
Page 18: Vacuum Piping
3.3 Vacuum piping (1) Before connecting the pipe to the pump, clean the inner walls of the vacuum chamber, piping and vacuum valve to completely eliminate moisture, fine particles, dust, dirt and rust. Note If fine particles, dust or dirt, etc are evacuated, the pump may malfunction. If moisture is evacuated, not only does the ultimate pressure increase but also the inside of the pump becomes rusty causing the pump to malfunction. -
Page 19: Electric Wiring
3.4 Electric wiring (1) The pump rotates in the clockwise direction as seen from the front of the pump (level gauge side). (2) When wiring, open the terminal box of the motor and connect the wires as shown in Fig. 5. (3) Please select the power supply cord with a suitable plug to the power-supply voltage, and connect wires by using pressure wear terminal (#250) with the insulation coating as shown in Fig 6. -
Page 20: Fig. 5 Electric Wiring Diagram
Note Check with a qualified electrician or serviceman when the grounding instructions are not completely understood, or when in doubt as to whether the product is properly grounded. Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a qualified electrician. Note This pump must be connected to a grounded, metallic, permanent wiring system, or an equipment-grounding terminal or lead on the product. -

Page 22: Operation
4. Operation 4.1 Cautions for operation Warning There is a risk of explosion. Never block the outlet or operate the pump with equipment mounted at the outlet side which blocks the passage of gas. Otherwise, the pump internal pressure increases causing the pump to explode, the oil level gauge to protrude or the motor to be overloaded. -
Page 23: Start Of Operation
4.2 Start of operation To start operation, close leak valve (B), open vacuum valve (A) to the inlet port, and turn on the power switch. Then the pump starts beings to exhaust (see Fig. 4). Caution ① The motor and pump become hot (temperature increase under non-load operation: 15K, temperature increase under high-load operation: 50K) during operation of the pump. -
Page 24: Operation In Cold Climates
4.4 Operation in cold climates When using the pump in winter, in cold climates, or outdoors, it is sometimes difficult to start the pump. This is an overload phenomenon resulting from the increase in the viscosity of the pump oil. To start the pump in such conditions, warm up the pump oil, or turn the pump on and off several times in short intervals. -
Page 25: Automatic Reset Type Thermal Protector
4.6 Autonatic reset type Thermal protector Auto reset thermal protector is incorporated in the motor in order to interrupt the power circuit of the motor and prevent damage to the motor when an over current flows through the motor due to a stop in rotation or overload resulting from the pump malfunctioning during operation. Table 2 Characteristics of the thermal protector Operation temperature 120±5℃... -

Should the motor be started up after resetting the thermal protector, a large current may continue flowing in the auxiliary coil, probably leading to its burnout. -
Page 27: Gas Ballast Valve
4.8 Gas ballast valve The pump is equipped with a gas ballast valve in order to evacuate vapor and condensable gases such as solvent vapor. Evacuated condensable gas that liquefies in the compression and pressurization processes of the pump is mixed with the pump oil and starts circulating through the pump together with the oil. In such a case, the same effect as when oil of a high steam pressure is used is produced, and the ultimate pressure of the pump increases. -
Page 28: Installation Of The Oil Mist Trap (Option)
4.9 Installation of the oil mist trap (Option) An oil mist trap can be installed in order to remove oil mist from the pump. As such an oil mist trap, models OMS-050 and OMT-050A are available. Remove the standard exhaust port from the exhaust port of the pump and install an oil mist trap instead. -
Page 29: Pump Performance
5. Pump Performance 5.1 Ultimate pressure The term “ultimate pressure” as employed in the catalogue and in this manual is defined as “the minimum pressure obtained by the pump without the introduction of gas from the pump inlet (i.e. the non-load condition).” For this pump, measurement is performed using the specified pump oil with only a Pirani vacuum gauge installed at the pump inlet port. -
