Performance Range:

Capacity: Q ~800 m³/h (~3522 gpm)

Head: H ~1200m (~3937 feet)

Operating temperature: T -80°C~+180°C

Description:

All spare parts are designed into standard size, the middle section is sealed by O ring and connected by bolts outside of the middle section. Metal composite wave tooth gasket can be used in special occasion.
The suction section and discharge section is generally foot mounted, and centerline mounted when the liquid’s temperature more than 150 °C.
Each type have two sets of impeller/guide vane, and the TDY pump have a wide high-efficiency zone. Changeable wear ring to seal between pump casing and impeller. Most axial forces is balanced by hydraulic balanced devices and other are balanced by thrust bearing.
Grease lubrication or oil lubrication.

Standard material:

According to API610 standard

Q: I just noticed a slight leak from my water pump. About the size of my fist. I called one mechanic and was told the 2001 BMW Z3's water pump seals are tight and do not leak with the car is running (engine is hot) but once the car cools the water pump seals expand resulting in the small leak, that I shouldn't worry about it unless it leaks more, the engine over-heats, or dash light turns on. The BMW said I should have the water pump replaced but he may have just said that to make a repair sale. Anyone out there know the truth?: Rarely do BMW water pumps leak a lot. Most would not even leak when pressure-tested by a mechanic (for a few minutes). But a leaky pump would leak when the engine runs and specially when it is pressurized and allowed to sit overnight. Usually the seal itself does not cause the leak. It is the wornout bearing which allows the pump's shaft to wobble and thus allow coolant to leak. Overheating due to air getting inside the cooling system is big trouble. But bigger trouble still is a catastrophic failure due to failed/seized water pump bearings. Have it replaced. And the previous statement that your car is about due for hoses and thermostat replacement is correct. There is even a chance that the thermostat is allowing the cooling system to get over-pressurized and thus results in coolant leaks. Replacing the pump is good, replacing the thermostat in addition is better, replacing also the hoses is best. If you can afford it.

Q: What I am trying to explain is that I took my vehicle to be serviced for a water pump. They installed it, but when I got my vehicle back, it started making this clicking noise. I took it back to be diagnosed and they came back to me saying that I need a new engine? (Before I took in my vehicle there was no clicking sound or problems, just the water pump.)Could this be the dealer trying to pull something for their mistake or what?: What kind of vehicle?' Depending on the car they may of had to remove the timing belt to access water pump and possibly not set timing correct or left a tensioner loose or soemthing. Did they tell you why you need a new engine?

Q: I am trying to increase the pressure of my shower and I am looking to install a water pump. Does anyone know what kind of pump would work well for this? I don't want a big pressure pump, just a small one that will be cheap.: its called a demand pump when you turn the shower on it kicks on

Q: How many kinds of pumps are there? What are the advantages of soft start?: The starting modes of water pump are direct start, star triangle start, reactance start, soft start, step-down start and frequency conversion start.1, direct start, generally suitable for small power motors, generally only in the following 15kw pumps, cheap;2, the buck start is the star triangle conversion start, that is, the start is accelerated two times to reach the rated speed, generally in more than 18.5kw pump use, moderate price;3, soft start is gradually increased to the rated speed, the impact on the pump is very small, the price is relatively high, is generally 3 times the buck start;4, the highest frequency conversion is started, in addition to the advantages of soft start, but also can be set at any speed work, energy saving has significant effect.Advantages of soft start:1, the output torque of the motor can meet the requirements of the starting torque of the mechanical system, ensure smooth acceleration, smooth transition, and avoid the impact of destructive torque;2, the starting current to meet the requirements of the motor capacity, to avoid motor heating, causing insulation damage or burnout;3, make the starting current to meet the grid power quality related standards requirements, reduce voltage sag amplitude, reduce the higher harmonic content.

Q: i was coming home from from work and my jeep thew the serpenteen belt and my water pump is the only pulley not moving good like the rest and is leaking coolent. and people with just dump **** to say dont comment on this: With either engine your jeep cherokee would have a 2.5 or 4.0. Both have the same pump, and the 2.5 would be easier because you would have more space from the smaller engine. But there not hard to replace. A repair manual would be help full if you have never replaced a water pump before.

Q: What's a small soft pipe for a submersible pump in a fish bowl? How do you use it?: Filter pump for oxygen spray. If the filter pump water flow, you can throw oxygen flowers, you can not use. With that pipe, it's loud and kind of

Q: i have a water leak near the water pump in my 1990 cadillac deville i replaced the water pump but it was remanufactured and a pipe on the back of the water pump can it be a heater core or should i buy a brand new one p.s. water leaks after it passes the radiator: this is why I do not buy remanufactured pumps, it is best to buy a new water pump if you can, it will last the lifetime of the car pretty much, remanufactured for what ever reason the water pumps just did not do the job, and I know my mechanic got tired of putting one on, only to have to take it off because it leaked, make sure the water pump is the problem though.

Q: Is it accurate to say that it should begin at 2, not at 0?: It freezes at 0 degrees, and the pump runs and gets stuck.

Q: Earlier today I was driving and my car shut off at a stop sign. I got it to start again and it shut off at the next stop sign, so after a few minutes I got it to start again and immediately pulled over as there was a small amount of smoke coming from under my hood. The temp gauge didn't say it was overheating, but I think it mightve been stuck, because that had to be what happened. After sitting there for a while it started and stayed that way for a while, I let the engine run. I drove it to the gas station and put some coolant directly in the radiator and the resevoir, and almost all of it leaked right out. I started to drive it home and had to pull over about 6 times to let it cool down because it kept overheating( temp gauge showed it this time). I think its the water pump that is leaking, but I know very little about cars, and was wondering if it could be anything else? Also, the heater wasn't working in the car today at all.: The heater wasn't working because you were losing the coolant. If the cooling system is not full, the coolant won't circulate and warm coolant won't flow through the heater core. But the water pump on the Neon is not a known problem. I'm not saying that it's not the problem but it's not common. What I suggest you do is fill up the cooling system with water and start the engine. See if you can spot the fluid leaking out. If it is indeed the water pump, the pump is driven by the timing belt so the water would be leaking out at the bottom of the engine on the passenger side. If you don't see the coolant/water dripping out under the engine bay, it could be a bad head gasket and the coolant is disappearing inside the engine ( check under the oil cap, if it looks like a milkshake film under there, it can be the sign of a bad gasket ).

Q: Well I know the water pump is leaking and its leaking fast. So I put water in the coolant reservoir and when I drive it acts fine but then when I stop and idle the coolant tank starts too over flow and spits the water out everywhere. Car still being at reg temperature the coolant reservoir is steaming/smoking? I can't tell which. But there doesn't seem to be water in the oil??? What's going on? If the water pump is replaced will this stop?: If you are loosing water due to a leak coming from your water pump the radiator can not hold pressure making the water over heat that is where the steam is coming from and as far as how long it will take you to replace the water pump time will tell if this is your first time it may take you 8 hours but like they say it is better to have tried than to have not tried at all.
