Gen-X Mak 4
 

This pump has really impressed me so far. It is quiet, handles pressure and provides substantial flow. They run relatively cool as well. I can't tell you long term how it'll be but so far so good.

I have the mak 4 and i think it is very good.and will buy more when i set up my 200gal.

Ok I am concidering this pump. has anyone used it on a becket skimmer? also are the threads on the intake and discharge external or internal? and what are you overall thoughts over the long haul>

Steve

Steve, the threads are external - have'nt tried mine on any skimmers yet, but been thinking of putting it on a AquaC style skimmer - great pump. :cool:

I run my 4 feet foamer becket with one http://zapzap.zwf.net/albums/Album-de-stephane/aej.jpg

also have another one to connect my 130 reef to my garage 8 foot below
+ 12 foot orizontal so a total of 20 foot hose and still have incredible flow

they draw only 1 amps or 110watt!!!

and for 200$$$$$

This pump is the best your money can buy IMO

I have compare it to a mag18,5MD litle giant,GX8500 on my skimmer an none of them is able to beat this pump

thanks Stephane, just what I wanted to see/hear. I think I just ordered 2 of them I am waiting for a confermation :neutral:

how loud are they Stephane?

Steve

I run one on my Beckett skimmer also and it works great. It's very quiet too. I can't hear it outside of my cabinet.

Steve, they are the best pumps for beckett skimmers.

Stephane, that is a dark looking collection cup :eek:

I've heard Mak 4's and they aren't super noisey, less than LG 4MD's.

I have one. It's not completely whisper-silent but it's the quietest pump that I'm currently running. Enclosed into a stand I can't really hear it at all (one caveat: I have a LOT of ambient noise in my basement).

I knew I was impressed with that pump but after seeing Stephane's 4' beckett skimmer now I am REALLY impressed.

Hey Stephane what diameter is that, is that 8"?

Well, after a lenghty look at the MAK and the velocity, I decided to go with the MAK 4's for two reasons; less heat and they are pressure rated. hopefully they will be here tomorrow or Sunday, as I also ordered bulkheads and I need to figure out what hole size they need so I can order the euro bracing for my tank..

Steve

I think it's 3/4" on both input and output. Can't remember :rolleyes:

Or do you mean hole size for the bulkhead? oops

yup :mrgreen:

Steve

Steve, don't know if this helps, but I used holes for 1" bulkheads and stepped it down to 3/4" tubing for the GenX. Schedule-40 1" bulkheads require a 1 - 3/4" hole.

well I ran one for a hour last night and man are they loud. mind you my stand was all open and such. is there any tricks for making them quieter? like putting rubber between the stand and them?

Steve

I have mine sitting on a mouse pad and the plumbing is the clear flexi hose so any kind of vibration might be absorbed. When the stand door is closed I don't hear much of it.

Sorry to hear yours is a bit loud... :neutral: Honestly mine is one of the smaller contributers to the "tank noise" phenomenon I have going... the fans are the worst.

well I picked up 6 feet of 10lb carpet underlay today so i am going to try that as a pad to quiet them down.

Steve

Think you got enough there ? ... might want to get a little more just to be sure :razz: :mrgreen:

Rasta, I think he means he got 6 ft. for EACH pump. I think it should work. I told him about the 2 pads and duct tape trick, but he didn't like that.

Home depot would only sell it in running feet the width of the roll, sence the roll was 6 foot wide......

I might try using it to line the stand as a sound proofing in areas to help cut down on the noise also.

Steve

ok I ran the pumps for 6 hours today and I must say I am totaly impressed with the flow, BUT they are way way to noisy. Soooo what I had decided to do is drill a hole (or 3 or 4) in the wall and run the pumps out to the garage because I can :mrgreen: this will solve the noise problem.

Steve

I like my idea better. :rolleyes:

ok where can I buy flexible PVC for a reasonable price? I need about 40 ft.

Steve

which one was that? drop it off at your house?

Steve

home Depot. If they don't have it, VanIsle will.

home depot doesent have any.. I guess I will stop off at VanIsle tomorrow.
