  • Page 12: Gas Ballast Control

    A73001880_M - Introduction The pump has an NW40 (item 1) inlet and inlet strainer. The pump mechanism is driven directly by a three‑phase electric motor. The motor is controlled by a drive, which manages the supply of current to the motor in accordance with operating conditions and allows the pump to be connected to a single phase supply.

  • Page 13: Construction

    A73001880_M - Introduction 2.5 Construction The pump scrolls are made of anodised aluminium. The motor housing is aluminium. All surfaces of the pump which are exposed to the pumped gases are free from copper, zinc and cadmium. Other materials of construction include fluorocarbon elastomer, nitrile, chemically resistant polymers, nickel, stainless steel and a PTFE composite material.

    A73001880_M - Installation 4.5 Electrical installation 4.5.1 Check and configure the pump CAUTION: Isolate the power supply before changing the voltage. Failure to configure the pump electrical supply correctly can result in damage to the pump. Ensure that the voltage shown on the voltage indicator (refer to Figure: General view on page 9) on the motor cover corresponds with the electrical supply voltage.

  • Page 23: Leak Test The System

    A73001880_M - Installation WARNING: If pumping for a prolonged period above 100 mbar inlet pressure, use an exhaust silencer (refer to Silencer on page 34) or connect to an appropriate exhaust line. Before connecting the pump to the vacuum system, remove the plastic cap from the inlet and exhaust and ensure the inlet strainer is fitted to the pump inlet port.

  • Page 24: Operation

    A73001880_M - Operation 5. Operation 5.1 Use of gas ballast control (if fitted) The gas ballast control can be used to optimise the performance of the scroll pump for the application. The performance characteristics of the pump with the different ballast settings are shown in Table: Performance characteristics on page 13.

    A73001880_M - Operation Switch on the electrical supply to the pump, using the Run/Standby switch Figure: General view on page 9, item 9. With manual operation always use the Run/Standby switch to start/stop the pump. If remote operation is used to control the pump, refer to Remote operation using 15-way D connector on page Open the vacuum system isolation valve (if fitted).

  • Page 26: Remote Operation Using 15-Way D Connector

    A73001880_M - Operation ▪ The inert gas purge should be switched on to remove air from the pump and exhaust before the process starts. The purge flow can be switched off at the end of the process only after any remaining flammable gases or vapours have been purged from the pump and exhaust line.

  • Page 27: Shut Down

    A73001880_M - Operation 5.7 Shut down WARNING: When the pump has been switched off the fan will continue to run for 1 minute. Use the procedure below to shut down the pump: If shutting the pump down prior to a period of storage, remove any process gases by running on high flow gas ballast for at least one hour.
