Description

The History of MoreBeer! & March
Many years ago MoreBeer! worked with March Pumps to release what is now the standard pump in the homebrewing community, their model 809 (our H315) with a polysulfone head and 6' cord with plug. Thousands and thousands of these pumps have been sold to homebrewers.

The New Design
Now, with a slight design modification, the new model nearly eliminates past cavitation issues (where the impeller spins in an air pocket and no liquid moves). We've been testing/using the pump with our BrewSculptures for several years now and are extremely happy with the results, so much so that we are completely replacing the H315 with the high flow model.

Still Works the Same
The new model comes with all the great features of the original - magnetic drive, handles flow restriction, okay for boiling temperatures, 6' cord with plug, food-grade materials in contact with the liquid, 1/2" ports, etc. - but now features a different slightly higher flow rate with less issues of cavitation.

The magnetic drive in a March pump acts as a clutch allowing the user to put back pressure on the pump to slow down flow. Since it is magnetic drive, it is not self-priming, you must put the pump below the level of the liquid source. This pump cannot be run dry.

Features List

Addtional Notes To restrict flow place a ball valve on the out flow of this pump.
This is the pump we install and use on all of our BrewSculpture brewing systems
We stock polysulfone replacement heads, H317, in case the threads are damaged. If you are looking for a pump for a larger home brewery or small nano brewery you can also look at our H325 Nano Brewery pump from March.

  • Included bracket for mounting
  • 6' power cord with plug wired in for easy use
  • Maximum flow of just over 7 gpm (at zero head)
  • Maximum head of 18 feet (at zero flow)
  • 1/2" mpt fittings on both inlet and outlet.
  • Materials in contact with solution: Polysulfone, 316 stainless steel, silicone rubber, Ryton and Teflon
  • 1/25 hp, continuous-duty, thermal overload protected, single phase 1.4 Amp motor
  • Motor is fan cooled
  • Will handle internal pressures to 50 psi.
  • Max temp rating: 250F
  • Face unscrews and rotates at 90 degree intervals to adjust to your application.

Note: When using silicone tubing, we recommending using a slighlty larger barb than the I.D. of the tubing. This is because silicone tubing tends to have greater pliability than most tubing. For example, when using 1/2" silicone tubing, we recommend our 5/8" barb (H620), to help ensure a better seal!

Great pumps
These are great pumps. They work very well but you have to make sure that you have adequate liquid flow to the pump since it will not pull liquid through a dry hose.

The plastic head is not a big deal for me since I have a valve and quick disconnects installed. It is tricky getting the valves threaded the first time so if you plan on screwing things on and off of the pump head, go for the steel head.

Great Pump
I've had this pump for a few years and it's a great addition to my setup. Once you get a handle on priming the pump, it's a breeze. I have it connected to a counter flow chiller and it makes cooling the wort very quick,easy and safe. Definitely recommend.

Great Pump, High-Flow Must Have
I have this pump and the 815 (non-high flow) and there is a huge difference. I never have to prime this pump, just open the valves and turn it one and it's pumping. I need to upgrade my impeller to the HF version at some point to make my old pump operate like this one. Never had any issue in over 3 years with this pump after dozens of batches. I do recommend buying some spare gaskets and nylon washers to have on had so you don't have stuck on a brew day.

Great for recirculating your mash
I love my March pump, and use it for recirculating my mash and cooling via my plate chiller.

I opted to use stainless quick disconnects at all of my pump, valve, and hose connections which makes re-routing the pump a lot easier.

Great little pump for the price
Had this pump for about a dozen batches and never had any troubles, even with boiling wort. Be careful with the plastic threads and keep the fan covered, though.

Great Pump
I have used this pump for two years without any issues. It's a solid workhorse pump that has been extremely reliable. I would definitely buy another.

I feel young again.
My back is happy with this work horse.

Great Pump, but Consider the Stainless Head
I use two pumps on my single tier stand. They both do exactly what I need them to do, but I didn't care for the plastic heads. The threads were finicky and didn't inspire much in the way of confidence. Once I replaced them with steel, I was able to get the connection I want and now I'm off and running!

how did I ever brew without a pump?
I don't know how I ever got along without one of these things. While i agree with the reviews that mention the plastic threads I've never had any issue with them because I immediately installed stainless sleeves and then added QDs to the pump so the threads have never been touched since and the pump has performed flawlessly

Excellent product!
I purchased two of these for my single tier brew stand. Both work without flaw. The only thing that could improve is if they came standard with stainless threads rather than plastic.
