you need to get a lot of horses
See discuss question below.
A sump pump usually uses 200-400 watts. So 3.5kW is way overkill. That should be about enough to power sump pumps for your entire block.
The brake horsepower varies as a cube of the impeller diameter.
Some do and some don't. Some use gravity flow and some use a diaphragm type fuel pump.
Yes, a sump pump can be connected to a generator to make it operate. Keep in mind that the starting current of the pump motor could be 300% of the running current and the sizing of the generator should take this into account. If you are looking for the sump pump using a mechanical connection it will connect to the engine and not to the generator.
Answer Generators usually always go by watts. To figure this all you do is take(volts x Amps) = watts. You know the volts (220) then look on the pump for the amp rating and then multiply them and you will have your watts. Then get a generator that is rated for this amount for continuos operation not peak watts. Hope this helps.
It would be recommended to observe the pump size rating (horsepower) and replace with a swimming pool pump that has a similar flow curve. In terms of brand name, there is no reason that you need to use the existing brand again unless you want to.
The 15 horsepower Mercury outboard motor does not have a water pump. The outboard motor is air cooled and does not have a need for circulating water.
Yes, a well pump can be wired to a generator but to find out how well it will operate the pump's voltage and full load amperage must be stated.
No, as long as the generator has sufficient KW for the pump's requirements. A 3/4 hp, 220V motor draws around 5 to 6 amps. That's 1.1 to 1.3 KW, but because motors have high starting current, your generator should be rated for at least twice that, preferably 3 times. I would recommend a 3.6KW 220V generator to be safe.
Yes you still need a pump and filter. The saltwater system generates chlorine and eliminates the need for chlorine tabs. You will still need to keep the water balanced and continue normal pool maintenance.
It could be a number of things. Your pump's operating voltage could be 240 volts and your generator's output is only 120 volts. The generators output voltage can be found on the generator's nameplate. The horse power size of your pump could be too big for your generator. When dealing with motors remember that when a motor starts its inrush could be 300% of the full load amps. To see if this is happening, take the full load amps and multiply it by 3. Then multiply that number by the voltage that the pump runs on. This number will be the starting watts of the pump. If this number is higher than that of your generator and the generator almost comes to a stop when the load is applied,then the generator is too small.
