Product Description:

LW Vertical Sewage Pump

LW series vertical non-clog single suction sewage pump, adopts non-clock anti-twisting big flow impeller, have very good handling capacity.
These serial pumps have two kinds of structure forms, one is motor and pump are coaxial directly, the other is adopting the shaft coupling,
The motor is standard vertical type. The inlet and the outlet have two kinds connecting form, first, horizontal suction, the inlet and outlet can be 0 ° 、 90 ° 、 180 ° 、 270 ° according to needs, second, the axial suction, for the convenience of vertical installation.

Q:When is it necessary to replace the timing belt and water pump on a 2001 Mazda Protege?
That could have either the 1.6 liter or 2.0 liter engine. My information shows that if you have the 1.6 liter, at least you don't have to worry about bending valves against pistons if the belt breaks -- you'll just be stuck out on the road until you can get it towed and fixed. Not so with the 2.0 which is an interference engine. So if you DO have the 2.0, pay attention -- you don't want an expensive breakdown! You're on borrowed time at 75K. For both engines, Mazda recommends that you replace the timing belt every 60K miles. Gates (a major replacement supplier) seems to think these belts will go 105K. Since it's a factory belt, stick with 60K. As for the water pump, it's often one of those while you're already in there sort of things when you're doing a timing belt. 60K makes it a tougher call, especially with the better quality of water pump bearings and seals. If your interval were 80K ~ 100K as is true on some cars, I'd say go for it without blinking. As cheap as it'll be (it's really just the price of the pump), and it was my set of wheels, I'd do it anyway, even at 60K, if it needed to be pulled to do the belt.
Q:how do I replace water pump so that water will be dispensed from refrigerator?
There is no pump in the fridge. Water is propelled by pressure before it gets to the fridge.
Q:When you change the timing belt do you also have to change the water pump?
The timing belt drives the water pump in your car. To replace the water pump, you have to remove the timing belt. When you are having the timing belt replaced, it makes sense to also replace the water pump. There is very little additional labor to do so, as the timing belt is already removed. You do not have to do so, but if you do not, and the water pump subsequently fails, you will be paying the full labor charge to replace it rather than just the cost of the part. As to the belt tensioner, I would replace that because it is a wear item, and if it fails it can cause a timing belt failure. If you are going to risk the timing belt failing (and causing major damage to the engine) you might as well not have the belt replaced. I would never replace a timing belt without also replacing the water pump and tensioner. It is false economy to do so.

Q:25KW what is the lift of the pump?
2 floor, the following formula is not accurate, the margin of safety is too large.N=Q (L/s), *H (m), /102/ (0.6~0.85), /0.85As follows: for reference only: (pump flow * pump lift) / (367* pump efficiency) * pump motor power safety margin (constant general take 1.1-1.2) = pump power.Unit: flow M3/H, head MNow you know the power of the pump, but you do not know the efficiency of the pump and flow, so the pump head can not be calculated.Can the normal operation of pump flow velocity detection using ultrasonic detection equipment, combined with the calculation of pump diameter of the flow and shaft power testing equipment can use foreign advanced measure pump, electric motor with related input parameters to calculate the pump efficiency. Then use the formula above to calculate the pump head.The simple way is to ask the designer directly about the design parameters.
Q:Yang Chengtai big, the pump power is too small, the water pump will be bad?
Related to water pump structure, when the pump head is higher than the rated pump head, the current will increase, the water discharged from the pump impeller, back to the inlet of water from between the impeller and the casing exceeds the rated value, if it is a high lift pump, clearance between the impeller and the casing is small, the water pump current increases with increasing lift, current too much faster than the rated value, the motor will burn; if it is a low lift pump design, when the clearance between the impeller and the casing of the strict requirements, and even some of the water pump, the outlet is blocked, the pump will not burn. The drinking water pump used on the table, generally used non-toxic latex diaphragm pump, the head is too much, will damage the diaphragm part, the motor because the circuit has protection, the motor is not easy to damage. Generally do not risk good, according to the actual situation, select the appropriate lift, suction pump.Yang Chengtai large! If the pump power is too small! The pump will break! But not necessarily bad, mainly determined by the pump structure.
Q:Why can domestic pumps sometimes pump water and sometimes not?
What floor do you live on? If your floor is relatively high, the noon is not good, because there are too many people in the water (and maybe someone else is using a pump), so the water level is too far away from your house to pump it up
Q:My brand new well water pump is acting incorrectly?
make sure your pump is wired 220vac. you need to restrict the flow coming out of the discharge of the pump when you are filling tanks/waterlines. Once everything is full and the pump is running at operating pressure it should quit turning off. as said above it is the thermal overload protector in the motor shutting it off. The more GPM you move the more current it pulls, current=heat. restrict it by turning your valve down by half or more.
Q:How can I be sure the water pump is the problem before spending $ on repairs. 97 civic overheating.?
Simple overheating is rarely the water pump. In most cases water pump failure means either a leak, which is visible as dripping from a weep hole under the car near the timing belt cover, or as a seized shaft, which would mean the engine would quit running immediately and probably be seriously damaged by failure of the timing belt that powers the water pump. Having got past that, consider the conditions of the overheating. If you are losing coolant, start with that. Verify the loss is not because of a head gasket by the simple test: with the engine cold, remove the radiator cap. Start the engine and place the palm of your hand over the radiator neck where the cap came off, and pinch closed the hose to the reservoir. If you feel steadily rising pressure within 3-5 seconds (if the idle is surging, ignore those changes) that is bad news for the head gasket. Otherwise move on. Look for leaks at the end of every hose by feeling with a clean paper towel on your hand, and look for whitish streaks around the top and bottom of the radiator. If coolant is not disappearing, the overheating must occur when in slow traffic or idling, or on the highway, or all the time. If it is when going slow or idling you probably won't see the fan running when it is hot. If it is on the highway, or if it gets hot and stays hot all the time, the radiator is probably plugged with hard water deposits from using tap water to dilute the antifreeze.
Q:How to identify the motor series of pumps
You can also use the motor speed divided by 50, equal to the motor series.
