What a bubble pump

foam pump, foam pump, foam with what pump

the fire inside need a bubble pump to pumping liquid protein concentrate, from fire station storage container to extract 500 gal bubble to the truck, ready to used in fire extinguishing chemical and petrol ( As shown in figure 7 1) 。 Although the fire industry consider use of vertical centrifugal water pump, centrifugal pump is not suitable for conveying foam agent, however, they produce a large amount of air, cause 25% of foam fire engines to concentrate, and 75% is a bubble, completely unable to effectively the fire service.

if want to completely without the foam pump with a foam fire truck need five hours non-stop work to do, For example, to be called in an emergency) 。 Usually the fire service company has three foam fire truck in the key areas, including near the highways, airports, large chemical plant. Artificial load foam fire truck's weakness is obvious, for example, when a gasoline tanker traffic accident on the highway, gas leak on the levee, a little fire burns quickly. Two special foam fire truck, fire chief realized a car standby, the other two cars can provide the whole foam fire protection cover will need at least 3 h, if the area is another major accidents, it is easy to be hurt. A large number of tries to use the centrifugal pump or results are not ideal after all kinds of self-priming pump. Therefore, in order to make the foam pump can be full of fire, to the foam pump manufacturer put forward a series of technical requirements, including: no gas in the liquid high and the operation is simple, reliable and safe operation, and long service life.

company can use this type of foam pump of screw pump or gear oil pump and their advantages are obvious. Fill a fire truck & ndash; — The 4 h takes two people to complete the task, now only need two people can be completed within 12 minutes. Screw pump used in the foam fire truck, it can greatly increase the efficiency of fire engines.

the other can be used as the bubble pump of recommended products are: pneumatic diaphragm pump

In an age when submersible pump is increasingly important, the researchers believe manufacturers should pay close attention to their results.
J&T INDUSTRY CO.,LTD. attaches great importance to customers and assists them in achieving their demands.
submersible pump allows users to use in innovative ways that fit their individual needs, while at the same time providing cost-effective, reliable and user-friendly products.
pool cover drain pump submersible pump is slower than winter cover pump but has a number of special applications, such as for pool cover drain pump.
If something seems too good to be true, then it can be a , which provides winter cover pump value over its cost.
