I have a 11/2 HP booster pump that is in-between a water storage tank and two pressure tanks to feed house water. Can I use this pump , even though its a sprinkler pump ? for a back up replacement ?
1 answer-
ProductExpert11· 4 years ago
It would not be recommended to use the pump for a booster pump application. The pump is designed for high volume not a high pressure application.

I am looking for a pump to pump down a small pond when it gets to full of water. There is a fair amount of organic material in the pond. Can this pump handle this organic material or must it be finely screened first?
1 answer-
ProductExpert31· 5 years ago
This pump could be used to move water from a pond. The intake should be screened to prevent solids from being pulled into the pump and causing damage.

We have a creek on our property that has water for 2-3 days after a rain. I need a pump that can run continuously for 48-72 hours before the creek dries up again. How long can this pump run before it overheats or otherwise needs a break?
1 answer-
ProductExpert31· 5 years ago
This is a commercial pump and is rated for continuous use. Provided there is adequate ventilation to the pump area it can run continuously without the need for a break.

Will go still get the same performance if you reduce inlet and outlet to 3/4” ?
1 answer-
ProductExpert30· 6 years ago
You would not get the same performance from this pump if the inlet and outlet were reduced to 3/4". Reducing the suction port on this Star Water Systems sprinkler pump is not recommended by the manufacturer. This would greatly limit the capabilities of the pump. Reducing the discharge port side only would still have an impact on the GPM performance for this pump too.

continuous irrigation
Can this pump be operated in continuous mode for several hours without tripping the heat overload?
1 answer-
ProductExpert40· 7 years ago
Running the pump for several hours should not trip the thermal overload unless there is a problem in pumps operation.
