  • Page 19: Installation

    A37132880_F - Installation 4. Installation 4.1 Safety WARNING: Ensure that the installation technician is familiar with the safety procedures which relate to the pump oil and the products handled by the pumping system. WARNING: If a hydrocarbon oil is used in this pump, do not use the pump to process oxygen in concentrations greater than 25% in volume.

  • Page 20: Unpack And Inspect

    A37132880_F - Installation ▪ We recommend the use of a foreline vacuum isolation valve to allow the pump to warm up before pumping condensable vapours or if a vacuum needs to be maintained when the pump is not running. ▪ Avoid high levels of heat input to the pump from the process gases, otherwise the pump may overheat and seize, and cause the motor thermal overload device to open.

  • Page 21: Fill The Pump With Oil

    A37132880_F - Installation sight‑glass is visible and the oil filler‑plug, oil drain‑plug, mode selector and gas-ballast control are accessible. If the pump is part of a permanent installation the handle can be removed to make the pump more compact. To remove the handle, cut the handle into two and remove the free portions from the pump.

  • Page 22: Check The Direction Of Rotation

    A37132880_F - Installation 4.6.2 Check the direction of rotation CAUTION: Ensure that the pump-motor rotates in the correct direction. If it does not, the pump and the vacuum system can become pressurised. Refer to Figure: General view of the pump on page Watch the motor-cooling fan through the fan cover on the end of the motor.

  • Page 23: Side Inlet-Port Connection

    A37132880_F - Installation 4.7.2 Side inlet-port connection A side inlet-port is available, refer to Figure: General view of the pump on page 11. To use the side inlet-port, use the following procedure. Carefully remove the side panel from the pump: use a suitable flat blade screwdriver or similar tool for this purpose.

  • Page 25: Gas Purges

    A37132880_F - Operation 5.1.2 Gas purges WARNING: If using inert gas purges to dilute dangerous gases to a safe level, ensure that the pump is shut down if an inert gas supply fails. WARNING: Obey the instructions and take note of the precautions given below to ensure that pumped gases do not enter their flammable ranges.

  • Page 26: Start-Up

    A37132880_F - Operation 5.3 Start-up WARNING: Ensure that the system design does not allow the exhaust pipeline to be blocked If the oil is contaminated, or if the pump temperature is below 12 °C (53.6 °F), or if the electrical supply voltage is more than 10% below the lowest voltage specified for the pump, the pump may operate at a reduced speed for a few minutes.

  • Page 27: To Pump Condensable Vapours

    A37132880_F - Operation Close the gas-ballast control. Open the vacuum system isolation-valve and pump down to ultimate vacuum. 5.5 To pump condensable vapours Use gas-ballast (open the gas-ballast control) when there is a high proportion of condensable vapours in the process gases: Close the vacuum system isolation-valve.
  • Page 28 A37132880_F - Operation this, use a gas-ballast control valve (refer to Solenoid operated gas-ballast control valve on page 38). We recommend, as described in the procedure below, decontaminating the oil before shutting down the pump, this will prevent damage to the pump by the contaminates in the oil.

  • Page 29: Maintenance

    A37132880_F - Maintenance 6. Maintenance 6.1 Safety information WARNING: Allow the pump to cool (so that it is at a safe temperature for skin contact) before starting maintenance work. Make sure the pump is switched off in case the thermal overload device restarts the pump.

  • Page 30: Check The Oil Level

    A37132880_F - Maintenance When carrying out maintenance on the pump, use our spares and maintenance kits, these contain all the components necessary to complete maintenance operations successfully. The item numbers of the spares and kits are given in Spares on page Examine the condition of any external accessory, filters or traps (if fitted) when carrying out maintenance on the pump.

  • Page 31: Replace The Oil

    A37132880_F - Maintenance 6.4 Replace the oil Refer to Figure: General view of the pump on page 11 for the items in brackets. Operate the pump for approximately ten minutes to warm the oil, then switch off the pump. (This lowers the viscosity of the oil and allows the oil to be drained from the pump more easily).
