User questions & answers

Question:	Can this pump operate at variable speed with proper wiring and parts
Answer:	Typically we use a 3 phase motor for VFD but I believe there are some VFD's that can work with these. You will need to work with one of our engineers to make sure this will function for your application. Irrigation-Mart
Question:	what is the flow rate at 60 psi
Answer:	According to the specification sheet, the max discharge pressure is 40 psi. The flow rate depends upon the amount of head from the pump to the final sprinkler heads. Go to this link for the curves associated with performance: https://documentlibrary.xylemappliedwater.com/wp-content/blogs.dir/22/files/2015/04/GTSALES-R1.pdf

Question:	How exactly would i wire this? do i need an electrician to come install a 220 box? where exactly do the wires go? any ideas/suggestions welcome
Answer:	Yes you need 220V for a GT20If you don't have 220v, you will need an electrician to run 220v to service the pump. You will need a 220v Hard wire connection to motor terminals inside the rear of the motor. (Under cover)

User questions & answers

Question:	Is this an on-demand pump and does it have a dry shut off? Thank you
Answer:	Hello, on demand is dependent on the irrigation controller and solenoid valves. This pump can work with with those components. Just make sure the irrigation system sprinklers heads are in sync with the GPM discharge of the pump. If you want guidance, please call us. Best regards, Scott 786-310-7384
Question:	I installed it but it doesn't pump water from our canal which is roughly 150 yards from the pump. Is it too small
Answer:	I have the same situation out of a pond with no problem. did you fully prime the pump? you could be sucking air some where in your piping or your pickup screen is full of mud packed solid. I think it is a great pump.
Question:	Trying to use this pump for irrigating greenhouse, will it work with 15 psi irrigation tapes? will installing pressure regulator cause back pressure
Answer:	Good morning, does the pump need to overcome any suction lift? Min discharge psi should be around 20 psi minimum. Best regards, Scott 786-310-7384
Question:	The pump will only build pressure to 30 pounds. What's up with that
Answer:	I'd like to know myself ! Flow is excellent but if pump runs with all valves shut - pump will not exceed 30 psi as you say. I wonder if there's some sort of internal "spring safety valve" that pops open when 30 psi pressure is reached and then water just free-flows around inside pump ? My "new" set-up shuts power off to pump at end of final sprinkler zone whereas before the increased pressure would do this when last zone ended. Very odd. I might call Gould to get explanation. Been tied up with other things - as are we all !

Note:

1, This is a submersible centrifugal water pump. It must be immersed in the water, or the water level of the external water source must be lower than the water inlet nozzle of the water pump when the pipeline is connected, so that the air after the water pump is discharged and the water is pumped normally.

2, The head of the water pump is the maximum water delivery height, that is, the flow rate to the maximum head point is zero.

3. This pump cannot work without water for a long time.

1 x 12 V G1/2" male thread brushless water pump

• Low noise (<35dB), small size, high efficiency, low power consumption, strong anti-interference ability, stable operation, safe and pollution-free.
• The stator and circuit board of the motor are potted with epoxy resin and completely isolated from the rotor, which solves the leakage problem caused by long-term diving of the motor-type DC water pump, and is completely waterproof (waterproof grade: IP68).
• The water pump shaft adopts high-performance ceramics (zirconia), which has high precision and good wear resistance. It adopts the precision matching of high-precision shaft sleeve and ceramic shaft, and has a long service life.
• 12V G1/2" male thread; Cable length: Approx. 50cm (19.7"); Maximum flow: 800L/H 210 GPH, Maximum llift height: 5M/16ft, Working temperature: 0¡æ - 65¡æ/(32¡ãF - 149¡ãF).

User questions & answers

Question:	Can this pump be mounted vertically
Answer:	Hello Keith, Yes, the 17A can be mounted vertically but please remember that the intake needs to be below the water line. This is not a self-priming pump. Regards, Xylem.
Question:	im using it foe a live bait well in the boat but you have 3 models what is the differences and which one should i use its a 55 gal
Answer:	It’s a 3800 gallon per hour pump. She would a little much for a live well if it is not a big tank. It would definitely work though. Make sure the pump is mounted as instructed or you will have issues getting water.
Question:	What is the temperature range for this pump? Can it be used with hot water
Answer:	I don't think so because all the parts inside are made of plastic. Normal use is for Salt water wash down pump or live bait pump.
