Chugger X-Dry (run dry protection) pump, stainless steel head, center inlet, 115V (XCPSS-CI-1)
Same pump as the now discontinued CPSS-CI-1, but with FDA Approved Run Dry Carbon Bearing Material. Pump should not be run dry on purpose.
Tough little continuous-duty pump that can be non-stop for extended periods. Handles liquids up to 250° F.
Comes standard with a non-locking plug with a 4 foot 7 inch long cord. To use with our control panels make sure to upgrade to the L5-15 (125VAC, 15A) locking plug.
Note: Changing the plug voids the manufacturer warranty. Extension cords are available which leave the warranty intact.

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, and China||China|
|In business since||1950s||2000s|
*Most Chugger pumps have 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(s). 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.
