GN – Economy – heating and ventilation pumps


The GN range is a competitively priced pump available on VERY short lead times. Offering an economical solution, this range features a close coupled design and is often face mounted. The pump also offers alternative mounting options. Various layouts include foot or flange mounted, skirt mounted direct to a motor. The GN range is also made as a Duplex pump set with a filter as one unit, often used for pumping generator fuel in buildings.

All of our Albany Pump styles have a variety of options for the customer to specify, allowing the solution to fit the exact requirements of the industry. With so many options available, no two pumps will be the same.

Suited to:

As one of the most robust and compact gear pumps in our range, the GN provides pressures up to 10 bar, with pre-set relief valves to protect the motor from overload. Each pump can be individually tested, and offers availability to work in normal, extreme or hazardous conditions.


  • A self-priming pump which supplies a constant, non-pulsating flow
  • Suiting a range of end uses, including; damp proofing, bottle washing, packaging, processing, pressure testing, transfer and more.
  • Options for a motor drive or bare drive shaft
  • Availability for packed adjustable gland, lip seal or mechanical seal
  • Rotational speeds between 100 rev/min and 1725 rev/min
  • Thrives in a variety of conditions from normal to extreme or hazardous


Our range of GN style pumps are very versatile, with its ability to pump:

  • Fuel oils
  • Coolants
  • Lubricants
  • Solvents
  • Bitumen
  • Liquid wax
  • Molasses
  • Cooking oil
  • Glue
  • Varnish
  • Detergents
  • Anti-freeze
  • Insecticides
  • Sodium hydroxide
  • Paints

Technical talk:

Being such an adaptable solution for those in the General & Chemical, Food, Sugar and Lubrication, Marine and Lubrication industries, there are many technical options to specify with this GN pump. Some of which being:

  • Pressure: GN pumps can produce pressures of up to 10 bar depending on the available power supply (kW) and liquid
  • Flow: the flow rate, as standard, is proportional to the running speed
  • Suction: this will vary depending to the shaft speed, viscosity and the vapour pressure
  • Temperature: when the GN pump is running at the recommended speed, standard pumps can handle liquids of up to 85 degrees Celsius
  • Rotors: fitted with spur gear rotors as standard
  • Rotation: the standard rotation is clockwise, from the drive shaft end of the pump. This will be standard unless requested otherwise
  • Viscosity: individually tested in oil, the viscosity will rise as the temperature falls. Note: viscous liquids will cavitate at high running speeds however this can be prevented by heating liquids to reduce viscosity pumping at low speeds, or both
  • Relief valves: pre-set to protect the motor from overloading and are not suitable for use as control valves. An external relief valve can be supplied
  • Sealing: lip seals are principle on all F type, packed glands on P type and nitrile mechanical seals on O type, with other options available
