Chemtech Series 100 Diaphragm Metering Pump, 230V, 30 GPD Max, San/PVC/CSPE/Ceramic Liquid End, .44" PVC X .50" PE Tubing, Model X030-XC-AAAAXXX

Item arrived well packaged, and with easily understood directions for the DIY project. Install took less than 45 minutes. Works perfectly and has a bleed value my initial unit did not have which is very useful. Found similar items online at double the price.

Been using this pump for years, my old one finally gave out. New one is identical, easy change out, good as before! I was pleased to get a bag with accessories that are needed for most systems. Still had my old ones that were working but decided to change them when I got them new as part of the package. Nice touch.

Big disappointment. For about 4-5 years I had a Pulsafeeder chlorine pump which worked fine but eventually parts started to break and I decided to order a new one. This time Pulsafeeder pump came with a different head pump, with one inlet and one outlet (previous one had also degassing outlet built-in into head). From start this setup was not working: constant leaks on threads, tubings not fitting properly and I had to do many runs to home centers to buy new tubing, new fittings, etc. Eventually, I gave up and ordered new Uni-Dose pump. I did installation of this one whiteout any problems - everything seems to be working and fitting nicely. I will see how long this will last.

I recently purchased this pump. It works very well. However, the piping was larger than my old one, so I had to adjust the dosage. Also, the instructions say that the pump head has to be vertical, so I had to change the way I mounted it to the wall. *** My only issue is that I keep getting small holes in the piping on the pressure side. I'm not sure if this is due to the piping being clear instead of black, as my order did not come with black piping. I'm going to Home Depot to replace the line with black piping and see if that solves the problem.

This is my second pump in 28 years. I purchased my first one from a local plumbing wholesaler and waited several week before I got it. This time around.. Amazon and the vendor turned around the order in a matter of three days! The back flow device is included with the pump this time around and last time I needed to buy one. So that is great and I highly recommend replacing that and the tubing when you replace the pump. It is very quiet and I use it for my Chlorine tank for my well water. I have high sulfur content with my well water and this pump is the answer to injecting Chlorine into the water when it first comes into the house. It is engineered great and keep in mind that if you have a 240v pressure switch on the well pump, you NEED a 240v injector pump like this one! Again, this is a great pump for the application I need it for and it comes with all of the tubing and connectors needed for proper install!

Nice and quite .. replaced a 12 year old chem-tech pump of the same model #.....that failed.. for a 35 gal. bleach tank.... nothing last for every.. but these pumps work great and last a a good amount of time...especially with bleach & water mix..

The price and easy installation was easy to read and replace my defective pump.

The pump is less than a year old that’s already leaking all down the diaphragm and all down the tank. I don’t want through the floor and I can’t seem to get any help from Amazon about this. Won’t even give me an option to email the seller.
