Last night wife asks if there should be foamy water on the floor of the equipment room.... turns out my low pressure presoak pump is leaking where pump and motor meet. Guessing its the pump shaft seal but neglected to ID the model of the pump while I was at the wash, only ID i could see was the Grundfos name cast into the end cap. D&S manual calls it part number PMP7144, but googling grundfos 7144 turned up no leads. Anyone know the model of pump so I can order a seal kit? Vintage around year 2000. I'm afraid the tire cleaner will take out the motor if I dont fix it soon. TIA.

Thanks Randy that pump has the correct D&S part number but looks different than the one in my 2000 model machine so I'm not confident that the seal kit will interchange. My pump runs and pumps, just sprays out at where the pump body mates to the casting that attaches to the motor. I'd be tempted to substitute another pump if it becomes necessary to replace the whole thing, but then again, everything costs these days.

Are using this pump on your self serve bays or on your automatic?

On the Automatic, it pumps the presoak at low pressure while the car enters and through the gantry on the presoak passes through as many as 12 nozzels at a time.

The only way to be sure is to get the exact model off the plate on the pump. It's on there somewhere.
