FIRE FIGHTING PUMPS
Link Pumps have been building fire fighting pump units for over forty years, some of the key areas have been servicing the special needs of supply vessels in South East Asia and other areas. These ships require standby fire fighting pump capability for protection of personnel on oil rigs where units are usually mounted above the water level on the open deck.
1. What Performance Characteristics do I need to look for in the pump?
Pressure: For firefighting, you’ll need around 100PSI or greater. Look at the specs of the pump you are considering, it will list in metres what is called the ‘Maximum Head’ – multiply this number by 1.42 to give you the PSI…e.g. if a pump has a Maximum Head of 75 metres, then its max pressure is approx. 107 PSI.
Flow Rate: Think about the sheer volume of water you need to move and the distance the water needs to be pumped. For most domestic use, anywhere between a 200 litres per minute up to 1000 litres per minute will likely suffice. In conjunction with flow rate, you need to consider Maximum Head;
Maximum Head: Again, each pump has a ‘Maximum Head’ specification; it refers to the maximum height the pump can pump to. If you have a pump with a maximum head of 60 metres, your flow rate will about zero at 60 metres. So you need to consider the difference in height between the pump and where you are pumping the water.
Inlet/outlet size: Firefighting pumps have inlet/outlet sizes typically ranging from 1″ to 4″ and greater depending on the flow rate required and they essentially draw in water through an inlet valve and then disperse it from a discharge valve. The larger the pump outlet size, the quicker the job will get done; for example a 6″ pump will finish a job 2 times faster than a 3″ pump.
2. What Physical Characteristics do I need to look for in the pump?
Self-Priming capability: The important “self-priming” capability of a pump comes from the pump’s ability to retain water after the very first prime. This will overcome the problem of air blockage and makes sure your pump is ready to fight fires when you need it most. Make sure your Fire Fighting Pump is self-priming.
Robust, metal build: Because of how firefighting pumps are used, their fixtures are generally made from metal rather than plastic, like the delivery outlet caps and body. Look for sturdy metal componentry in your firefighting water pump. Beware of cheap pumps using plastic elements as these can often cause you issues under higher demands.
The 300 x 250 – 500 LINK FIRE FIGHTING PUMP is specially designed for best efficiency at 1200 tonnes/hour. Low NPSHr, minimum deck space and an extremely robust mounting point for the monitor, have all been incorporated into this purpose designed fire pump.
