Viking at the Museum: The Ice Breaker Mackinaw

On December 17, 1941- just 10 days after the attack on Pearl Harbor- the United States Congress approved the construction of the Coast Guard Cutter Mackinaw WAGB-83. The purpose of the ship was to forge a path for transport ships by breaking up thick ice that formed on the Great Lakes during frigid winter months. This allowed iron ore…

Use of Bitumen & Asphalt: The heat is on

Asphalt, also known as bitumen, is a sticky, black, and highly viscous liquid, or semi-solid form of petroleum. Asphalt is man's earliest organic engineering material. Its application as an adhesive and waterproof material dates to the dawn of civilization. The asphalt market thrives today largely for road building,…

Viscosity Through Thick and Thin

Viscosity is a measure of a liquid’s resistance to flow. And you don’t need to work in a laboratory to observe this. Anyone who’s spent any time in the kitchen has observed a variety of liquids with a wide variety of viscosities.

7 Things You Want to Know about Flanged Ports, but are Too Afraid to Ask

Flange standards used on Viking pumps have been in place for over a century so EVERYONE should be experts on this now…right? It turns out not so much. There are various standards and various design differences in each standard. AND the standards have evolved over the years, leading some to use obsolete terms which only compounds the confusion. The following should help clear up some of this…

PUMP CAVITATION: THE SYMPTOMS, CAUSE, DIAGNOSIS, AND CURE

Customers don’t ask me to listen to quiet pumps. This is symptom #1 of a cavitating pump. The pump is loud. Descriptors like “growly”, “rumbling”, or “gravelly” are used to describe the atypically loud sound coming from the pump.

“Does it always sound like this?” I ask.

“No, it was fine in the fall, but it’s been loud all winter.”

Relief Valves: The ever-vigilant heroes

Millions of homes around the world are fitted with water heating devices such as boilers or water supply heaters. Should they overheat, pressures can rise internally until the tank ruptures. Though extremely rare, this does happen and can even propel a water heater like a rocket through the floor and roof of a dwelling. So how can we sleep peacefully each night with the…

It Flows Both Ways: a guide to running an internal gear pump in reverse

One of the biggest limitations of a traditional centrifugal pump is its inability to reverse the direction of flow. By design it can only be run in one rotation and one direction of flow. Liquid enters the eye of the impeller at the suction port (typically on the front of the pump), is pushed out radially, and exits the pump at the discharge port (typically on top of the pump…

Banana Pumps and Star Gears: A guide to pump industry slang

A gentleman once contacted me to let me know that he’d cracked a head, an impressive, but not entirely unheard-of feat.  When I asked how this had happened he admitted “well, I was wailing on it pretty hard”; I appreciated his honesty.  What followed was a 30-minute conversation full of mis-assumptions and confusion.  At the conclusion I discovered that he was not talking about a head (as in…
