  • Page 3: Introduction

    1.1 Scope and definitions This manual provides installation, operation and maintenance instructions for the DRV3, DRV5,DRV10, DRV16 rotary vacuum pumps. You must use your pump as specified in this manual. Read this manual before you install and operate pump.
  • Page 4: Importance

    CONFORMITE EUROPEENNE - Comply with the EU "technical coordination and standardization of new method" basic requirements of the directive. WEEE - When the end user is going to discard the product must be sent to the appropriate facilities, for recovery and recycling. The direction of motor - Ensure that the pump-motor rotates in the correct direction.
  • Page 5  Never place combustible materials around the motor or pump. There is a risk of fire. Also, do not place objects that block ventilation around the motor. Abnormal heat generation may result in burns.  Do not operate the pump in hazardous area (where there is a risk of creating hazardous atmosphere by explosive gas).
  • Page 6: Description

    2 Description The DRV series pumps are compact, low noise, two-stage, oil-sealed, high-vacuum pumps designed for reliable, long-term operation in both laboratory and industrial environments. A four-pole three-phase motor provides direct-drive through a flexible coupling. Features of the pump include the following: 1.

  • Page 10: Installation

    4 Installation 4.1 Locate the pump Install the pump horizontally to a place where are less dust and humidity. Ambient temperature for operation shall be 5 to 40°C. The layout arrangement should be considered for setting up, overhaul, checking or cleaning the pump. The pump is equipped a handle and rubber isolators as standard.
  • Page 11: Electrical Installation

    4.3 Electrical installation WARNING Before connecting wires, you must be turn off the power switch. If not, an electric shock will occur. Connect the earth wire correctly. Install a suitable overload protector for capacity of the motor, otherwise the motor will be damaged leading to fire. Connect the wires according to indication on the motor nameplate.
  • Page 12: Check The Direction Of Rotation

    4.4 Check the direction of rotation WARNING The direction of rotation is as indicated by the arrow mark cast on the motor fan cover. Ensure that the pump-motor rotates in the correct direction. If it does not, the pump and your vacuum system can become pressurised. If it is reversed, interchange K1 and K2 for single phase motor and interchange two of the three wires for three phase motor.
  • Page 13: Outlet

    4.6 Outlet The pipe caliber connected to the outlet side should not be thinner than the outlet diameter. Otherwise there is a risk that the pressure inside the pump will rise up to cause break of the casing or oil level gauge, or overload of the motor. Oil mist would appear through the exhaust side when the pump running around high pressure range, discharge it to outdoor or an oil removing device through exhaust piping.
  • Page 14: Gas Ballast Function

    5 Gas Ballast Function This product is installed with the gas ballast function (G3/8 plug screw in the gas ballast port) as standard. It can be used with connecting needle valve or pipes. The gas ballast function is applicable to exhaust the condensed gas such as water vapor or solvent vapor. Breathed condensed gas shall be liquefied through the compress process of the pump, mixed with the pump oil and then cycled mixed together inside the pump unit.
  • Page 15: Maintenance And Check

    6 Maintenance and Check 6.1 Regular check You should check following points at least once per three days during operation. Check the machine much more frequently during high overload operation (continuous operation 1kPa or more, repeated exhaust atmospheric pressure-vacuum). 1. Whether the pump oil volume is between two level lines or not. 2.
  • Page 16: Change The Pump Oil

    CAUTION Continuous operation one hour or more at high pressure (1kPa or more) would decrease the oil volume that are discharged as the oil mist and cause parts wear rapidly or cause trouble such as burning. You are recommended to control the oil level on regularly supplying the pump oil. It is recommended to install the oil recovery mechanism (Option).
  • Page 17: Abnormal Noise And Vibration Check

    attained by oil change, sludge or other deposit may have collected on the bottom of the pump case. In that event, overhaul is required. Contact with us. CAUTION The pump oil might deteriorate in a shorter time depending on the use. It is recommended to replace the first pump oil within ten days after operation start and see how it got dirty to determine the oil replacement cycle.
  • Page 18: Checking The Metal Mesh At The Inlet Port

    6.5 Checking the metal mesh at the inlet port The suction inlet might be clogged by the dust contained in the gas breathed in from the vacuum chamber and thus the pump performance might be impaired. If the metal mesh is dirty, please wash it.
