Product Description:

Type Description

6620×4

66 series number

20: pump type

4: four-stage impeller series connection

Application

66 series pump is single suction multistage submersible pump that can applied to farm irrigation, garden sprinkling, fountain landscape, rainwater recycling system, mining drainage, emergency rescues, urban water supply, enterprise and government intuition water lifting. It can be used in horizontal position(while its service life will be inferior to that of vertical using). This product has some advantages of low noise, high efficiency and energy saving.

Its suitable for enterprises and public institutions such as bath center, district heat supply, power generation, underground hot water lifting. Different specifications and types provided for different wells.

Structure description

66 series submersible pump applies the space conductance guide valve structure, and it composes of pump, motor, controller. The pump contains working part, pipe (including check valve ).

1) working part

For pumps with strong axial force, we equipped with balance hole in order to relieve the pressure, then the motor could bear the rest.

We are strict about the concentricity and axial movement. With exquisite accessories and accurate axial locating dimension, the machine has a long service life and can be operated smoothly and reliably.

2) Pipe

The pipe contains check valve, discharge pipe and pump frame. Outlet of check valve is connected with the discharge pipe to prevent the water regorging when the power is cut off. Water flows out from check valve through discharge pipe, pump frame, ground gate valve and pipes to the destination. The pump frame is fastened on the concrete plinth, supporting the whole weight of the pump.

Medium Range

1        Clean water, cold water, rainwater, gushing water of mining, drinking water,etc.

2        Water temperature range: +5--+105

3        Solid content (mass ratio): ≤0.01%

4        PH: 6.5-8.5

5        H2S content: ≤1.5mg/L

6        Cl- content: ≤400mg/L

7        The full set must be submerged into water completely in vertical position and the model must be matched with the well diameter.

Motor Parameter

The submersible motor is lubricated by clean water. It must be filled with clean water, or else its service life will be lessen. If you forget filling, the motor will be broken.

Q:Automatic water pump!!?
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:Whats wrong with my car? replaced water pump and runs weird.?
Ive seen this before. u replaced the water pump, which means u drained the coolant, replaced the pump, and filled it back up again. When u filled it back up u created big air pockets in the coolant system. Small air pockets are always in the system, but wont cause a problem. Big air pockets cause the engine to idle rough, like its misfiring. Then when u go to press on the gas it stalls, or it wont rev past a certain point. Ive had this problem myself a few times, replacing water pumps and lower radiator hoses. About the best thing u can do is just let the car run and idle for an hour, maybe even 2! Then rev it when its still parked at a higher RPM, just to flush out those pesky air pockets. I know it wastes gas, but thats what i think the problem is. Air pockets are something that most ppl dont think about when they drain and refil the cooalnt components.
Q:2000 Mitsubishi Eclipse GS: Water Pump?
The water pump seal will go bad if it isn't already because you are adding plain water to the cooling system! Antifreeze has a rust inhibitor and a lubricant in it and if you don't have the correct strength mix the inside of the block rusts and then the heater core and the radiator get plugged up resulting in hundreds of dollars in repairs. The water pump if leaking will drip on the passenger side from under the timing belt cover if you let the motor idle for 5 to 10 minutes. Look for the drips on the inside of the RF tire. If the water pump is leaking the timing belt will jump and bend all the valves.
Q:Bad water pump diagnose?
There is a weep hole on water pumps that will leak coolant when the pump goes bad. The housing could be cracked or there could be a leak in the gasket. When it's running, see if you can see where the coolant is coming from.
Q:Help replacing water pump in Chevy Impala 2003....?
The PS pump is held in place by three 13mm bolts. Turn the pump pulley to align the holes in the pulley to the bolts behind it and use a 3 in. extension on a short 13mm socket. Then remove all the bolts. You do not have to completely remove the pump, just move it up enough to access the water pump bolt.
Q:TDH what units are present in the pump parameters?
TDH, Total, Discharge, Head, that means the head, the unit is usually feet. 1 feet =0.3048 meters.
Q:Water hand pump for invention?
your question is not clear, do you need to build the pump from scratch or you should find one? what is the water flow rate? how high the water need to go? what the helmet has to do with the problem? simplest solution will be to go to the store and buy small hand pump (for fuel).
Q:what am I doing wrong with my water pump install?
It is either configured wrong, (or wrong part number form the factory) or you are putting the pulleys on wrong. You may have left a spacer off, or one or more pulleys is installed backwards or in the wrong order. Make sure the one you have is for the exact engine and options that you have. There are differences for having A/C or not, and other things. Go to a different auto parts store, and compare water pumps from a different supplier. Sometimes they make mistakes when they assemble them, sometimes they assign the wrong part number to them, and sometimes some customer buys one and returns another.
Q:Does this water pump exist?
Maybe you have to drill a sperate well.
Q:Does a Water pump have to stay running?
No this is normal when you flush it should come on
