@itsmoked: I will definitely try using a globe valve downstream of the pump and see the effect.
@dpc: The name plate just shows 230/460V. I talked to the manufacturer and they said this motor also works with 208V, but it is a very minimum voltage. When we ordered the pump, we indicated that out...
You are right. Basically the design pressure is 251 PSI @ 338 GPM. When I move my nozzles (It is a huge Gantry with lots of nozzles), due to movement of they rubber hoses the pressure ramp up to 275 PSI or drops to 251 PSI. Either way, my operating point is moving on the pump curve and I'm not...
On the discharge side of the pump I have many nozzles that they are supposed to spray on the car. The current operating point is almost in the middle of the pump and I think the motor should be able to handle this load.... If I close the downstream valve it will increase the pressure after the...
Hi Everyone,
I have a problem with a 75 HP motor and I hope someone could help me with that. We have installed a 75HP Gould pump in one of our car wash facilities. The model# is 66SV-6/2. Our voltage is 208V and the wiring configuration is DELTA. Our operating pressure is 275 PSI which is a...
