Using Madden Heat Exchangers for Pump Seal Flush Cooling

Why Cool the Pump’s Seal Flush?

Certain types of centrifugal pumps and rotary pumps need their mechanical seals flushed out to achieve high reliability and effective sealing performance. The API has established piping plans for these seals. API Plan 21, Plan 22, Plan 23, and Plan 41 all require a heat exchanger to cool the seal flush liquid before being injected into the seal. This is where Madden Manufacturing comes in. We manufacture some of the most cost effective and durable liquid to liquid heat exchangers (sometimes directly called Pump Seal Flush Coolers) that the market has to offer.

When a centrifugal pump is pumping hot liquids there is potential for dilution and vaporization of the liquid. Cooling will improve lubricity and reduce the possibilities of dilution and vaporization, thus creating a more efficient and durable seal.

Madden’s New Product Development, Part 2

What’s New for Madden in 2016? Part 2

As mentioned in our last blog, the Madden Milk Cooler™ is in the works. We’re excited at the potential of working in a new market. The idea behind this actually came from an attempt at rejuvenating our agricultural business with our metering pumps. While on a local farm the question, “how important is it to get the milk cold as quickly as possible” came up. After some discussion it was deemed worth looking into.

The discussion was based on the idea that small farms would always be interested in products to ensure milk quality, specifically pre-cooling milk before the cooling/storage tank. However, most of them could not justify the expense of a plate heat exchanger, which depending on farm size, can range anywhere from $3,500 to upwards of $10,000.

Are Madden Sample Coolers the Best Bang for your Buck?

“Largest heat transfer surface, per unit of cost, of any sample cooler”

– Competitor on their Sample Cooler Line

Probably depends on the year and conditions of supply chain if we’re all honest, but in any case, we’d argue our line is on par with any of our competitors’ pricing. This blog idea was written due to a combination of coming across this marketing statement and having heard from our distributors that our sample coolers are the lowest in cost.

We wouldn’t claim this as a norm. Madden typically competes in this industry via quality, dependability, and responsive customer service, while maintaining competitive pricing, not best pricing. When it comes to price we usually hear things like “cost effective”, not “least expensive”. So in this case we thought why not use it as an excuse to share more on our sample cooler product line.
