Genesys Pumps Gain High Acceptance in Aquaculture Market

Michael Paquette, Hubbs-SeaWorld Research Institute writes:

“As an aquaculture engineer, working with salt water systems, the pump on a system holding thousands of kilograms of fish is an important selection. To me, a good system pump will be reliable, energy efficient, quiet, and will put out lots flow at low head. Finding these traits in available pumps at a reasonable cost had been pain staking. Anticipating the release of the Genesys line which had promises of meeting all my desires, I hopped on board and put in three units. I’m happy to say, I wasn’t disappointed.”

If Quality, Longevity, and Efficiency are NOT Important, then a Sequence® Pump is NOT for You!

If Quality, Longevity, and Efficiency are NOT Important, then a Sequence®  Pump is NOT for You!

For over 30 years Sequence® pumps have continued to offer the lowest purchase price and annual operating costs when it comes to your pond pump.  We frequently hear from homeowners that replacing their old submersible pump (after multiple failures) with a Sequence® pump actually made this hobby fun again.  Inquire today about how a Sequence® pump can lower your monthly power bill, and give you more time enjoying your pond, instead of replacing faulty equipment!

Genesys Pumps Gain High Acceptance in Aquarium Life Support Markets

Landrys Restaurants or the Downtown Aquarium has replaced two long-coupled 3x2x6

Joe Jacques, Director of Life-Support for the Downtown Aquarium in Denver Colorado writes:

“My name is Joe Jacques, and I’m the Life Support Manager for the Downtown Aquarium in Denver. My staff and I are responsible for the maintenance and operations of all the equipment used in keeping our animal collection safe, healthy and easily viewed by visiting guests. That makes it extremely important to utilize the best equipment we can both find and afford for the task at hand. Our exhibits require pumps and motors that can run reliably,efficiently and economically 24/7. I believe we found such a pump in the Genesys 2x3x6. We had two Genesys pumps replace a set of Ingersol-Dresser pumps (B73.1 compliant) almost a year ago. Right out of the box these pumps had several advantageous features. One, it is a close-coupled pump rather than the Ingersoll long-coupled pump (B73.1 compliant). This gives the Genesys a  space saving smaller footprint with no need for realignment after a mechanical seal service. With the Ingersoll (B73.1 compliant), I would have to either dial align or laser align the pump/motor after such a service. This was either costly, time consuming or sometimes both. Another advantage is the ease of actually servicing the mechanical seal. It is a very simple task, easily accessed with no tolerances to adjust. Incredible time saver. We’ve been running these pumps 24/7 for almost a year without any problems at all. The efficiencies are equal to or better than the Ingersolls’ (B73.1 compliant). The Genesys pumps also run quieter and cooler. All in all, we are very pleased in the performance of the Genesys 2x3x6 pump and plan to slowly phase out the Ingersoll-Dresser pumps (B73.1 compliant) in favor of the Genesys. It is on the top of my 2011 wish list to purchase at least two more of these pumps early next year.



B73lean™ The Pump Pays for Itself!

If you think choices made by your predecessors based on 1978 standards are good enough, . . .   then B73lean is NOT for you.

B73lean™ The Pump Pays for Itself!

For many applications, full compliance with the B73.1 standard can be a burden simply because you must pay for features you don’t need.

There is a more efficient alternative!

B73lean reduces minor features and cost while improving process performance and energy efficiency.  The result is a product that becomes a compatible replacement for ANSI/ASME 2-3-6 B73.1 pumps…all with lower acquisition costs, lower running costs and lower maintenance costs.

B73lean™ is easier to maintain

Its interchangeable design fits the old B73 input/output envelope but with a smaller footprint. Standard mounting, close coupled, direct back pull-out design eliminates alignment and calibration issues.

B73lean™ is less expensive to operate.

Smooth, resin-rich thermoset surfaces, elegantly simple design and fewer components make it far more efficient than the old pumps specified by

your predecessors.

B73lean Less Waste is More Profit.

Genesys Pumps Gain High Acceptance in Waste Water Treatment Markets

International Rectifier has replaced a Fybroc 3x2x6

Rick Blunt, Facilities Maintenance Team Leader at International Rectifier Corporation writes:

We purchased these pumps on the recommendation of our local vendor, who said that I would be very pleased with the performance.  Upon delivery of the units I was concerned about their ability to do the task because they had a smaller footprint and lower power requirements.  These concerns were short lived however, because once we got them started up we found that not only did they exceed the design criteria; they did it at a much lower motor speed, with less noise, and less operating vibration.  A wonderful pump, highly recommended.”

Introducing the Advance 4000

The New Advance 4000 Pump

As a result of high demand in recirculation applications requiring flow rates above 60 GPM at lower head pressures, we’ve taken all the great things from the tried and true 1000 series and expanded them to the new 4000 series.

Achieving over 200 GPM and a max of 35 PSI, the 4000 broadens the range of performance in the Advance pump series.

Inlet and discharge ports are both increased to 2″

▪ Inner diameter connection of FNPT

▪ Outer diameter buttress threads for union adaptors

Field installations become less burdened; eliminating reducer-fitting and adapter-assembly costs and reducing fiction losses in pump systems.All units come standard with polypropylene casing.  All mechanical seal and elastomeric options are the same as the 1000 series.

The Sequence SunPump

What you see here is the beta test-site for the Sequence SunPump 1000.  This application is nestled in a somewhat remote location in the foothills of the Rocky Mountain Front Range .  We’ve been testing this particular Sequence SunPump 1000 in an off-grid application since May 2009.  Stay tuned as we add a flowmeter to the system and gather GPD (gallons per day) from the Summertime sun-hours here in Colorado.
