Boiler Feed Pump  Brief

This pump is horizontal sectional multistage centrifugal pump,due to high pressure and big flow ,widely application for boiler feed industrial,mining,water supply for high bulding,water circulation system,oil field ,etc

Because of different design,it can be divided into five type pumps:

1.D series pump:the medium temperature is not exceed 80°C, applicate to supply and discharge water for high buildings, resident,mine,fire fighting, pressure boosting and refrigeration water circulation for air conditioning, etc.

2.DG series boiler water feed pump:medium temperature is not exceed 160°C, applicate to transport hot water, such as water feed to bolier, municipal and industrial heating system.

3.DY multi-stage centrifugal oil pump: transport oil and oil product without solid at temp range -20—105°C, viscosity is less than 120.C.S.T

4.DF series stainless steel anti-corrosive multi-stage centrifugal pump: transport corrosive liquids without solid at -20—105 °C

5.DM series wearable mining multi-stage centrifugal pump: applicate to transport mining water with particles <1.5%,size<1mm, -20--105°C..

Q:1993 honda civic how to change water pump?
water pump is timing belt driven, so you have to pull all of the belts off, the timing belt cover and that belt also. if that belt has not been replaced in 80,000 miles. you want to do that. i had a 93 civic and a 90 civic that i did the belt and pump in at 230,000 miles. it takes a little time but it is not that bad. the harmonic balancer has to come off for the timing belt also.
Q:Where online can we find a small water fountain pump?
www.okorder.com
Q:is it safe to drive 1.3 mile (no hill) with dead water pump?
1) it is safe to drive 1.3 miles if the weather is cold and you do not have to idle a lot - You are MUCH safer having it towed and do you want to risk an engine over a $75 tow fee? I would tow it 2) you should probably have to pay for the water pump - there is no way to prove it did not break while you were driving with it overheating, there could have been parts while you were driving. It is too bad they use plastic vanes now days, old water pumps could have taken the wear. It would be a lot cheaper if you could replace the water pump, but it can be very hard with modern vehicles. I would do my 69 Chevy myself easy but I would have to examine the Taurus before I would brave it out - $600 might be reasonable for a dealership to replace a water pump - I hope you find a mechanic you trust.
Q:Water well pump, always on??
very okorder.com and ask a question with the right keywords. Might be why you got a good deal on the house. Did you have it inspected or buy coverage? check it out they may pay for the new well.
Q:How can I test how high a water pump can pump to, using only pressure simulation?
Install a pressure gauge at the pumps diischarge line and note that p=wh. H =p/w, H =p{(144)/62.4}/3.28 meters Pressure expected therefore in psi, is p={62.4/144}3.28 p=14.9 psi A pressure gauge of 0 to 50 psig range would be sufficient to indicate the expected pressure.
Q:97 Grand Prix Water Pump removal?
here is a step by step on how to re move the pump is a lot easier than tring to pull off the pulley plus it will not come off when it on the engine there is no room for thr puller.
Q:Dry Bearing in my water pump?
i havn't heard of that, but i hear new things every day, sounds to me like it could be timing belt or gears, or a bad W/P it happens if he says its making noise tell him you would like it replaced under warrnty, cuz any were you get them they have at least a 1 year on them, cuz if you pay for a part weither it works fine or not, should not make noise it is not supose to.......i work for NAPA auto parts.....and ask were they got the pump, if he sayz auto zone you best tell them to get the sec on some were else
Q:Does anyone know how much a water pump would be for a ford taurus?
well thats gana depend on the year and engine size but i would say that you can plan on spending between 30 and 70 dollars
Q:How to stop water pump from leaking on 1999 grand Prix?
You will need to remove the water pump and see how far down the bolt broke. You may be able to get hold of the bolt with vice grips and get it out. Worse case you will have to drill it out and re-cut the thread or use a bolt extraction tool, you simply drill a hole smaller than the bolt and the extraction tool turns the opposite way to the bolt thread and as it gets tight its meant to loosen the bolt in question. I have done this many times and it dose not always work so you may need a professional to do it.
Q:Water pump "rated lift: 6m" what do you mean?
Popularly speaking, "lift head" is the ability of water pump to lift water. 6m means that the pump can pump water to the height of 6m.
