  • Page 34: Dry Pumping Systems With Optional Castors

    M58800880_H - Installation 3.1.1 Dry pumping systems with optional castors WARNING: Dry pumping systems fitted with castors should only be wheeled short distances over flat surfaces. If the floor surface is uneven or has obstacles, the dry pumping system should be lifted with suitable lifting equipment. Dry pumping systems are supplied with an option of skids or castors.

  • Page 35: Lubrication

    M58800880_H - Installation ▪ Dry pumping systems with skids are provided with four off mounting holes in the floor mounting plates as detailed in the installation drawings. ▪ All dry pumping systems can be secured by fitting the bolts or studs (not supplied) through the mounting holes in either the mounting plates or seismic restraints.
  • Page 36 M58800880_H - Installation CAUTION: The dry pumping systems have a maximum continuous exhaust line pressure limit. Operation above the limit may damage the pumping mechanism. The medium duty dry pumping systems have an exhaust pressure sensor which will initiate warnings and alarms when the pump is operated for at least 20 seconds above the limits given in Table: Pump protection sensors.
  • Page 37 M58800880_H - Installation than these limits, consider using an adaptor on the pump exhaust and a larger diameter pipeline. ▪ For pumps running on dusty processes, we recommend that the exhaust line is cleaned regularly as part of routine maintenance. Accumulation of dust in the exhaust line can reduce conductance and therefore increase exhaust pressure which may damage the pump.
