Experience the Cloud Difference at Your Facility


Cloud Maintenance Manager / Product Specialist Russ Lomanto has been busy visiting wineries, breweries and food production facilities throughout central and northern California in our new Mobile Service and Demonstration Sprinter Van.

On the service side, the fully-equipped van allows us to add significant value for our customers by providing tank cleaning machine maintenance and customer education in the field. We're not only repairing machines; we're teaching maintenance staffs how to minimize downtime and increase machine life.

On the demonstration side, there's no replacement for seeing the cleaning capabilities of a Cloud tank cleaning machine paired with our new 15 HP centrifugal pump in person. Behind 125 PSI of pressure, we're using the Cloud Model 360 tank cleaner to clean tanks lined with challenging materials like heavy tartrates and pulp in a single 25 minute cycle. Some of these tanks are currently taking many hours, and even days, to clean!

The Cost of Low Pressure

When it comes to tank cleaning and sanitizing, the vast majority of the wineries and breweries that we interact with are unwittingly costing themselves time and money due to a hidden problem: low pressure. 

Contrary to popular belief, pumps do not create pressure; they create flow. The best tank cleaning machines, like our Cloud Model 360, efficiently harness the flow from the pump to maximize impingement, but they do not create flow themselves. So even though pumps (and tank cleaning machines) don’t technically create pressure, you can easily get an idea of how much impingement you’re getting by slapping a pressure gauge on your pump.  This will allow you to see how much pressure your pump/tank cleaning machine set-up is producing.

 The amount of pressure that the pump “produces” is directly proportional to the speed (or velocity) of the water as it travels from the nozzle of your tank cleaner to the inside wall of your tank. At a high-level, impingement is essentially a function of momentum. Momentum = Mass x Velocity. Mass is controlled by the nozzle size of your tank cleaner, and generally doesn’t change during the tank cleaning process. Velocity is the result of pressure (although it is also influenced by a number of things that we’ll discuss in future articles including: distance of throw, angle of attack, rotational speed/angular momentum). That’s why, in general: less pressure = less velocity = less impingement = more time spent getting your tank clean.

So just how much pressure does a tank cleaning machine need to clean effectively? We say at least 100 PSI. You may be able to get a tank clean using less than 100 PSI by running your equipment longer, but longer run times come at a cost. First and foremost, time is money. Secondly, running a pump at maximum output for extended periods of time will lead to the pump requiring more maintenance, a greater chance of complete breakdowns, and expensive repairs.

 For those unable to properly clean their tanks due to issues with low pressure, high payroll costs and employee safety can also be topics of concern. We recently visited a local winery that had their employees manually scrubbing the interior tank walls from ladders because the winery lacked the appropriate pump and tank cleaner to do the job. The process was extremely labor intensive, and took two days per tank to clean!  For demonstration purposes, we ran our 20 HP pump (capable of 120 PSI) and Model 360 tank cleaner for one 20-minute cycle, and thoroughly cleaned an entire tank. 20 minutes…

 Investing in a tank cleaning pump capable of achieving 100 PSI or more should be an easy decision for your operation. You’ll save time and money, improve  safety and morale among your maintenance staff, and increase the time and man-power you have available to focus on your core business goals.

10 Year Anniversary of Sellers Acquisition

In May, Cloud Company will celebrate its 10-year anniversary of the Sellers Cleaning Systems acquisition! Sellers has been in business since 1871, and in 1989 became Cloud Company's North American distributor after Cloud ended its relationship with former distributor, Sybron Gamajet™. In 2005, Crane Pumps & Systems (Sellers' parent company) decided to pursue the divestiture of Sellers, so it could focus on building their Pump products division. This divestiture was finalized in May 2008, when Cloud acquired Sellers and moved all manufacturing to San Luis Obispo, CA.  Mike Kemp, the Sales Manager for Sellers, already having sold Cloud products alongside Sellers' from 1989 to 2008, continued in the same capacity with Cloud (where he is currently in his 35th year of service to the industry).

Before acquiring Sellers, Cloud was the designer, patent holder, and manufacturer (OEM) for the Model 1804, and all versions of the Model II and III (sold through Sybron Gamajet™), and the current Model 360, 363, 180, 700 and SVRU family. The acquisition of the Sellers product line was a natural fit since it allowed for access to a broader line of Rotating Tank Cleaning Machines across all industries, an excellent customer base and sales network, and it resulted in a consolidation of manufacturing facilities in San Luis Obispo, CA.
Beyond inheriting a fuller product line, Cloud Company inherited Sellers' rich history. Founded in 1871, William Sellers & Co (then Bankcroft & Sellers) started out as a machine shop, much like Cloud. Their first cleaning product was William Sellers' improved design of the Giffard Steam Injector, which became well known worldwide as the B, BX and BZ Steam Injectors. In the 1940's, the need for the elimination of manual cleaning, as well as improved overall cleaning, resulted in the addition of Tank Cleaning Machines which could be used with the Sellers Injector feed units, or pumps, for more efficient cleaning inside vessels. The first models developed were the 2" and 3" Troll Ball, following shortly by the Jumbo 6, for cleaning of larger tanks and vessels. The Tankman was designed in 1980, and the Orbi series and Tankmasters were designed in the 1990’s. The product line continued to expand in 2017 with the release of the Hygienic models.
Today, we are proud to carry on a long tradition of continuous innovation and quality manufacturing in America.

New gear in foreground.

After many months of R&D and testing - Cloud Company is excited to begin shipping our updated version of bevel gears for the Tankman,  Jumbo 6 and Hygienic 80!

What is different?

1. We have eliminated the sharp points on the outer diameter of the gears allowing easier and safer handling of the Tankman and Jumbo. Our assembly professionals really appreciate this feature and so will you. 

2. A more robust supply chain. Gear cutting is a time consuming process that tends to create a bottleneck in production. By adopting this new approach to gear manufacturing we have reduced lead time substantially.

Will these work with older gears?

YES, the new and improved gears will work with the old style. There are no compatibility issues whatsoever.

If it ain’t broke, why fix it?

Here at Cloud Company, we believe success lies in continuous improvement and innovation. Small changes like these make it possible for us to deliver the highest quality tank cleaning machines at a better price while keeping jobs in America!
