Pump Applications


Civil Defence

This List Can Cover Almost Every Application:

  • Emergency water supply
  • Emergency flood control
  • Supply of fire fighting water
  • Forest fires
  • Tanker filling
  • Emergency chemical and hazardous material wash downs
  • Control of crashed tanker liquids.

Civil defence is the organisation dealing with civil emergencies on land and river areas.

Fire Brigades

Fire Fighting and Fire Stations

Finding water in or out of city areas can be difficult and the supply water to appliances can be critical. Good automatic suction and priming can be of interest to many brigades and emergency services. The removal of water after fire fighting, clearing of mud and slurries after emergencies; emergency control of oil spill; the pumping and transfer of foaming agents, (A.F.F.F's foaming concentrates as it does not significantly increase the volume).


  • Flood Control: Mud removal and general over pumping.
  • Tanker and Vehicle Accident: Emergency and general sump pumping. Flooded basement and street pumping; removal of flood water and sewage.
  • Civil Defence: To cover for many civil defence situations, long difficult suction lines to gain water for fire and dosing; to aid in times of flood; to transfer fuel and potable water; to reduce water pressure on land slides and to control rising waters.


Pollution & Environmental Protection

Oil Spill Equipment Manufacturers

Major source of sales. The Selwood range, particularly the Selwood Spate, has a good track record of operation, working with most of the worlds skimmer manufacturers. The pumps have been used in almost all the countries in the world and have been used on almost all of the major oil spills. Many of the Skimmer manufacturers are now concentrating on industrial applications which helps sell our pumps in two ways. The industrial skimmer and pump are often supplied as a package which in turn leads to more sales for free standing pumps as the operators understand the abilities of the pumps.


The maintenance and environmental departments should all maintain stocks of equipment to react to spill emergencies.

Tank Farm Areas and Tank Storage Operators

The same as above for emergency occasions.

Pipeline Construction and Operators

Another group that are well aware of their environmental responsibilities so they maintain a stock of emergency equipment. These are often handed over to the pipeline operators after the completion of construction.

Port Authorities and Oil Jetty Operators

The biggest group of end users, reacting to regular small spills world-wide. This group also have to decant visiting vessels of bilge wastes, oily water wastes, waste water and sewage.

Marine & Marine Transport

All sea and inland waterway vessels have to have pollution control facilities on board by international law. This would include fuel bunkering and distribution companies at any coastal facility.

Naval Authorities Fuel Handling

Like all marine vessel operators they have by law to carry emergency oil spill handling equipment.

The Military

This is becoming an interesting end user as they play hard and often have tanker accidents and spills while exercising. This sector normally goes to international tender.


This section has a bad record of small spills of gasoline and diesel. However, in some cases, they do stock emergency equipment. Most marinas are now required to provide boat pump out facilities as per the recently introduced ISO standards (Spring 1998).

Industrial Applications

This section is having to learn the hard way. The fines are becoming more regular and expensive. Such organisations as power stations, major road haulage companies, large bus and public vehicle handling companies, pharmaceutical companies, pipeline operators, tank farm operators, engineering manufacturers, plant and vehicle maintenance yards, paper pulp industry, industrial waste treatment companies, car and truck manufacturers.

Other Organisations

This section would include, local environmental offices, city hall environmental departments, environmental agencies, water supply and waste water companies, mines and quarries, industrial waste companies, contaminated oil treatment and collection organisations, municipalities, coast guards, telecom companies, Civil Defence departments, fire departments, contaminated ground treatment companies and big farming organisations, motorway and expressway operators, mine and quarry wash plants and piling and construction companies, particularly those that work near or on marine projects.
