GB – Heated and unheated pumps

The new AP & HD versions

Summary:

The GB range is a heated gear pump (unheated option available) designed for pumping products that have to be heated to be pumpable. The design can incorporate heating by thermostatically controlled electricity, thermal oil or steam. Heated gear pumps are typically used for Bitumen, Crude Oil or Refined Tar among other generally viscous fluids. Our pumps are often supplied with a greaser which can be mounted remotely to allow easy greasing of the seal cartridge and give the best possible service life. The GB style features a seal cartridge to avoid leakage normally associated with bitumen pumps.

Suited to:

Often maintenance free, GB pumps are perfect for market sectors that require long and consistent pumping. Offering a simple and hard-working design, our GB pump range is most suited to:

Technical talk:

Our GB pumps have a range of uses, stemming from their formerly known name of AP and HD pumps, which are:

  • Cast iron: usually used for pumps up to 200 degrees celsius. At even higher temperatures, cast steel is used
  • All pumps have hardened steel shafts
  • Pump inlet and outlet: connections available to suit individual requirements, however DIN PN16 is standard
  • Relief valves: can be fitted to standard pumps
  • High temp: special high temperature bearing material is used to ensure long life
  • Gland packing: selected to suit individual application
  • Albany seal cartridge: can be used as an alternative to packed
  • Electric heating: can be 110 volt or 230 volt. Up to 1200 watts is available to keep the pump at 120 degrees celsius with a thermostat
