Propeller Pump Product description

QZ series axial flow pumps are modern products successfully designed through adopting foreign modern technology. The new pumps’ capacity are 20% larger than the old ones. The efficiency is 3%-5% higher than the old ones. QZ series pump with adjustable impellers has the advantages of large capacity, broad head, high efficiency, wide application and so on. Pump station is small in scale, the construction is simple and the investment is greatly decreased. This can save 30%-40% for the building cost. It is easy to install,maintain and repair this kind of pump. Low noise,long life.

Q:Hit and Miss Engine Water Pump?
A horse and a half won't do much. You would be better off with a hydraulic ram type pump if you can get about a 10 or 15 foot fall before the ram. It will pump about 4 or 5 times the height of the fall, but in small quantities. It will run 24/7 without gasoline, so it will fill a tank over a long period of time. The railroads used them during the steam era when they had huge water towers out on the plains.
Q:My water heater pump keeps tripping the main electric panel...?
sounds like you have dual gas waterheaters, and the recirculating pump isn't doing what it shoudl be? if somehow, there is a short in the electronics of the pump, it would cause the electrical panel to trip. Still sounds like an electrician would be your first best bet, since it's not strictly a plumbing issue, but also electrical problem. Those pumps are designed to run with about 65 to 150watts power, which would NEVER cause the breaker to trip. If the breaker is weak, or there is an electrical problem that caused the breaker to weaken, an electrician will still be the better bet than even just having the pump replaced or calling in a plumber.
Q:LSvtec Oil and Water Pump Question?
you need the GSR/Type-R water pump. This is one of the major causes of LS/VTEC failure. The GSR/Type-R has 22 teeth while the LS/GS has 19 teeth. The extra teeth cause it to spin faster pushing more water through the system. Any time you change something related that uses the timing belt, I ALWAYS install a new timing belt, and tensioner. That way there are no worries later.
Q:How many kilometres should a water pump be changed on a toyota hiace 5l engine?
no set mileage. no service interval for that above a visual inspection. should i replace water pump as well YES!!!!!!!!! water pumps are a consumable item. don't wanna do that much labor again soon. i strongly suggest you pay the extra bucks and get a toyota AISIN pump. it will last longer than any after market one hands down. do check for a front main crank seal leak as well. it's part of the oil pump. personally, if it were me, i'd do all three. belt, pump (from toy will be pricey, but worth it), and reseal kit for the front main (is 10-15 bucks and not much more labor).
Q:Acura 1.7 EL Timing Belt and Water Pump replacement?
The timing belt is the connection to all your other belts. If it snaps while driving it, it will need re-timed with a timing machine. Usually by a mechanic. I suggest replacing that ASAP. As for the water pump, they last a little longer but if you notice your car's temp gage going up in heat every now and then, the water pump might need replaced. good luck!
Q:Can I install a recirculating hot water pump to a boiler?
I merely positioned one in my homestead and did no longer use a pump. Mine is precisely gravity. I decrease into (with a tee setting up) the present warm water feed line at a factor which became farthest from the water heater and then deliver a clean line back to and teed into the drain on the very backside of the heater. I positioned a diverse off valve interior the line merely up from the hot tee close to the drain so it quite is adjusted or close off if mandatory. (Mine is open and has been considering I put in it) some structures could require a verify valve interior the hot return line on the horizontal area of the return line close to the water heater. I positioned one in in spite of the fact that it does no longer enable my equipment to artwork so I bumped off it and all is definitely now. All you're doing is making a loop so the nice and comfortable water is often circulating from the heater by way of the feed lines and while it cools slightly it returns by potential of gravity to the tank. this is the very ultimate subject I even have accomplished in some years. this gives you instantaneous warm water and no pumps, no electric use. you may learn this equipment on the internet. merely Google for it. solid success
Q:How large is the starting current for a 1.5 kW submersible pump?
If single-phase, the no-load current is about 3.7A, the rated current is about 10A.
Q:Does the lift of pump relate to the water level of import and export?
Pump head refers to the inlet and outlet pressure head, that is to say, the entrance resistance greatly affects the pump lift, of course, this inlet resistance has a degree, too large water pump does not bring water or cause water pump cavitation. If the water level at the pump inlet is the same height, the inlet flow resistance of the pump may not be considered.
Q:When using a frequency converter to adjust the pump, what is the relationship between the change of the speed and the efficiency of the pump?
The wind pumps such load is usually called square torque load, which is in a certain range of speed and torque is roughly proportional to the square of the speed of N, TL=kn^2, power and speed is proportional to the cube, the energy-saving effect is obvious.
Q:So im trying to take out a screw on my water pump?
If there's tail of the screw still out ,use an alligator clamp wrench . clamp it as hard as you can ,then spray some WD-40 waite 5 minutes and then try to open it . If it brake from inside the trade ,there's no way except drill small size hole than the screw, in the screw and then use left turn opener wrench (buy it from auto zone or home depot) direction of the use it's on the Package .It is a left turn traded screw with square end . After you get ride of that screw for re installation use high temperature grease and apply to the tread ,make sure pump cap it's not deform ,if is deform buy new and apply grease to the washer gasket before install .
