Capacity: 72~20000m3/h.

Head: 6.8 ~ 186m

Instruction of pump type
For example 10SA(SAP)-6JA
10-The number obtained from the inlet diameter divided by 25(inlet diameter is 250mm)
SA(SAP)-Single-station double-suction centifigual pump with horizontal split

S: Single-stage double-suction centrifugal pump with horizontal split casing.
6-The number obtained from the pump specific speed divided by 10.
J-The rated speed is changed

A-Outer diameter of impeller is changed.

Structure
The pumps is horizontally mounted, the pump casing and pump cover are divided along the axis. the upper is the cover, the lower is casing, the inlet and the outlet are on the pump casing under the axis, and their centerline is perpendicular to the axis, the rotor elements will be removed without disturbing the inlet piping, the outlet piping and the motors, only dismantling the pump cover while inspection.The shaft seal is either packing seal or mechanical seal（single end surface non-banlancing type).
The direction of rotation
The rotation of the pump rotor is counter clockwise looking from the motor to the pump, i.e. the inlet is on the left and the outlet is on the right. The driving end may be moved to another one according to customers'requirements, meantime, the rotation,the direction of the inlet and the outlet are opposite to the above -mentioned.

Material of main parts
The medium-contacting parts are made of cast iron.
The material of impeller: May be cast steel /brass /according to customer’s requirements.

Features of the SAP pump

1. The rotor elements are propped up with two bearing points, so it is stable and low noise in operation.

2.Double-suction impeller itself can balance thrust.

3.The shaft with changeable sleeve is protected from wearing and has a long life.

4.When you dismantle the cover and put it to a secure place, the rotor elements will be removed for inspection.

5. It's unnecessary to dismantle the inlet piping and outlet piping while maintenance.

6.Thre are packing seal and mechanical seal in seal ways, customer may choose it according to the requirements.

7.Remained water in the inside of the pump can be completely drained, so the pump is not damaged by frost in cold places.

8. The pump uses rolling dearings, it runs for a long life, it is easy for maintenance.

The material of main parts of pump

Pump, motor and coupling, common bedplate will be supplied when inlet diameter is less than 200mm.

Q: When you are replacing a water pump on a vehicle, should you replace the timing belt on the vehicle as well?: No. However I think you may be confusing the timing belt with the fan belt. Typically the timing belt is located within the engine. Some european models require this belt replacement. Typically 75 to 90 thousand miles. The fan belt, which is the belt that you can see in the front or side of the engine does need replaced occasionally. However just because you are changing the water pump doesn't mean that either of these belts need replaced. If the fan belt has cracks in it, then yes I would go ahead and change the belt at the same time that you are having the water pump changed.

Q: I'm just wondering where I should buy my new water pump for my 2.2 cavalier? Auto zone, carquest, checker? Does it matter which one?Thanks: They all buy their water pumps from the same manufacturer. Beware !!! Don't trust the location of the weep hole from the original pump to line up the replacement. Don't trust the directions on the new pump to find the top for alignment. Unless the new pump lines up perfectly, rotate it until the bolt holes line up PERFECTLY. If the bolts are hard going back in, the pump is misaligned.

Q: Water dispenser in refrigerator has stopped working, how do I replace pump?: The water supply is connected to a solenoid valve on the back or under the refrigerator. The valve is controlled by a timer. This timer lets water in through the solenoid valve to fill tray, and then shut supply off, it also supplies power to a motor to dump the tray once the water freezes.

Q: I just put a new water pump in my jeep and after I put it in I ran it and it seemed to have a small leak while it was running it seems like it was coming from the crank which is under the water pump so it might be a leak coming from the bottom of the pump. When I turn the car off it is no longer a leak its more like pouring water out. What do you think it can be? I put a gasket and the blue silicone gasket sealant all around it and on it before I put it in so I have no idea. Thank you for the help.: Sound like the new water pump is junk. The water is leaking out of the weep hole. That is a hole designed to leak when the pump bearing is going bad. It is a safety precaution so you don't fry the bearing and lock up your pulley system.

Q: Does the pump accessories have a shelf life?: Yes, 3-6 months for wearing parts, 12 months for general accessories, 10 years for shell type. Specific depends on whether the materials and user use conditions are bad to decide.

Q: Hi,My problem is of this automatic water pump ,it is disrupt always I don't no why..I also want to knew what is the function of the pressure air tank??? The picture is here:: WHAT does it is disrupt always really MEAN?? OK, that said... pumps such as this work to maintain a pressure with two set points even though the regulator only has one indicated.. The lower set point which as pressure drops, the pump turns on, and the upper set point where when the pressure rises to that point, the pump shuts off. When the pressure drops to the lower set point, it triggers the pump to run. When the pressure rises to the upper set point, the pump turns off. If the set point is 50 pounds, it may turn on at 47 and off at 53, or the window could be smaller and on at 49 and off at 51. The air bladder works as a shock absorber, just as the shocks work in your car to smooth the ride. When the pump turns ON there is a pressure pulse that without the air space, would promptly turn the pump off again. This is called short cycling and will cause your pump to on-off-on-off-on-off rapidly. The solution is to refill the air bladder. People with well pumps instead of city water have this problem frequently as the air bladder loses the bubble and does not work as a spring or shock absorber. I have city water NOW, but I used to use a well (which is still operational if I choose to use it) and I experienced pump short cycling the very first year I bought the house. The thing IS, I was ignorant. I missed the thing about a well and a septic tank that also uses a pump to an above ground drain field. YES. I was STUPID because I had NOT paid attention. NOW, years later, I have learned, the HARD way mind you, how these sanitary systems WORK in real life in RURAL America....

Q: My 1998 Dodge Dakota V6 heater only gets warm, I have replaced the thermostat. I have back flushed the heater core. The heater hose coming from near the thermostat gets hot, but the hose coming from the heater core going to the water pump only gets warm. The large hose coming from the thermostat is hot near the engine, but is only warm near the radiator. Is the water pump bad? If I open the radiator cap there is no signs of circulation. How do I check the water pump?Thanks,Gene: to answer your question directly, you can check a water pump the same on any car. water pumps have whats called a weep hole there is a small hole that is designed to leak coolant when your water pump seal goes out. find the pump and see if there is a trail of white from this 'weep hole' then yes your pump is bad. if not, i dont know the layout of the hoses for your car so i couldnt diagnose it for sure. but check your water pump for the signs i gave you. its a tell tale sign

Q: A tank is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 for g and 3.14 for pi . Round your answer to three significant digits.)The tank is a spherical shape has a radius r= 6m and a spout height of h=2m.I really dont know how to start this problem correctly. Any help will be appreciated. Thanks!: The pump will not have to work until the water drains by gravity to the level of the spout. Then, Work = Weight of water * Height of lift Find the distance, d, of the center of mass for the remaining water in the bottom 2 m of the sphere. The height of lift will then be 2m - d. The hardest part is finding the distance d to the center of mass. I don't remember how to do that.
