This pump features a stainless steel head that is much more resilient than the more common polysulfone (plastic) heads found in some models. Very important if you plan on adding stainless fittings such as a coupler and elbows as the plastic heads are easy to crack when tightening.
The pump's magnetic drive acts as a clutch allowing you to put backpressure on the pump to control liquid flow. We recommending doing this by placing a ball valve on the output (never the input!) of the pump. This is one major advantage of a magnetic drive pump: They are perfectly safe to run with the output completely blocked, completely stopping the flow of liquid. You won't harm the pump motor.
One disadvantage of magnetic drive pumps however is that they are not self-priming (they cannot clear air in the input lines by themselves). This means that these pumps must be placed lower than the liquid source so that gravity feeds the pump such that the the pump head becomes flooded before being turned on.
The larger 3/4" center positioned inlet (as compared to the more common 1/2" bottom-positioned inlet) makes priming easy. A common complaint from brewers with 1/2" inlet pumps is that they require extra work to prime through specially installed bleeder valves and/or by playing with the hoses. These are not required when using this pump and following our brewery design.

March? Chugger? What's the difference?
For brewing purposes both manufacturers offer pumps with similar performance characteristics. The differences are somewhat more intangible:
|Max flow rate||8 GPM||7 GPM|
6 foot (115V)
3 foot (230V)
|4 foot 7 inch|
(2 years if warranty card is registered)
|Manufactured||March manufacturing plant in Glenview Illinois, USA||China|
|In business since||1950s||2000s|
*Chugger has two thrust washers (one large, one small) while March only uses the smaller one that sits closer towards the motor. Thrust washers are bearing (contact) surfaces and do need to replaced periodically as they wear out. Most brewers should get a few years between replacements. If the pump starts to make rattling noises it's time to check the thrust washer(es). More information.
Plug and cord upgrades
Optional upgrades are available to include a NEMA L5-15 (125VAC, 15A) twist lock electrical plug and to have the cord wrapped in 1/4" carbon colour expandable braided sleeving with 3/8" black heat shrink tubing at each end.
We use and recommend turn-lock or 'locking' plugs as they plug in like any normal plug but then are turned slightly to lock them in place to prevent accidental disconnection. While not absolutely required, it's an added safety precaution.

Manufacturer Limited Warranty
March pumps are guaranteed against defects in materials or workmanship for one year from the date of manufacture. Warranty will be extended for up to one year from the date of purchase, provided that the warranty card is returned to the factory within 10 days of the purchase date. In all events, liability is limited to the purchase price and to the replacement or repair of any pump or parts defective in materials or workmanship. All pumps for which a warranty claim is made must be returned to the factory with shipping costs prepaid. This warranty is void if the pump has been subjected to misuse or negligence. This warranty applies only to pumps used to pump water or wort. For applications with all other solutions, contact the factory for verification of warranty terms before the pump is installed.
