purchasing a sequence dart pump, black or blue

[golfish]

Unless things have changed, the Dart only comes with the Hubble motor, if you can get the Baldor motor then that's the ticket. You want to stay away from the blue Valute cause its going to crack, but MDM is really good about replacing them. Probably the best customer service I've ever seen.

FWIW, I have a year old Barracuda in the garage that I'll let go cheap...say 135.00 (Hubble motor)

Oh yeah, if you going to reduce the inltake (2") or the output (1.5") on the Dart your going to reduce the flow, A LOT..These pumps don't handle pressure, at all. I don't care what MDM says, if you reduce the intake you reduce the flow. When you reduce the output to say 1" you'll cut the flow by 60%, atleast.

from what I understand the dart is pretty silent, how is the barracuda?
and what is wrong with the hubble motors?
anyone?

Golfish, very well explained. I had to learn the hard way.

Spend the extra $30 and get the SW series instead. They are the same pumps just built in the USA and of higher grade materials.

Just got this email from MDM Sequence because I was wondering what was the difference between the Sequence 750 and the Dart


"Hi Mike-
First off, the Dart and 3600SEQ12-SW are almost identical pumps. The 3600 is part of the Sequence 750 series and comes standard made with freshwater seals. The Dart is part of the ReeFlo series and comes standard made with saltwater seals. The only difference between the Dart and the 3600 is the color of the plastic housing. The watt draw and flow rates are exactly the same since they use the same motor and same impeller. You are noticing a difference in price because the Dart is mass produced while the 3600 has to be specially fitted with saltwater seals and is made only per customer order.
The average watt draw per Dart is 135 watts while the average watt draw per Hammerhead is 335. So you are correct in that running 2 Darts would be less watt draw then running 1 Hammerhead. However, when running 2 Darts, you can set them up in 1 of 2 ways. The first way would be to run them in paralle to increase your flow. That will give you up to 7200gph at zero feet of head, but they can only overcome up to 12ft of head pressure. If you are looking for more head pressure and less flow you can run the pumps in series and you can have a maximum of 24ft of head pressure but only a max of 3600gph. Please refer to the following website for more details. http://www.mdminc.com/Multiple_Pump_Curve.htm
Hope this answered all your questions and let me know if there is anything else that I can help you out with. Thanks,

I wish those flow charts would show the flow rate using different size pipe or "Nozzels"

If the Hammer head draws 335 watts where did JD come up with 400 for the Cuda

as mentioned before the blue housings crack and leak, Reeflow will replace them for free because it is a defective part, but you have to pay for all shipping charges, ( funny how their part is defective and the customer still pays the shipping )
and your out a pump for a couple weeks, best bet is to make absolutely sure that the pump you buy has the black housing.
