Product Improvements from Fluid-o-Tech and Grundfos Ring in the New Year

First of all, we’d like to wish everyone a happy and prosperous 2013. We’d also like to thank the best people in the world for making it a great 2012: our customers.

The New Year is a great time to reflect on the past, learn from it, and look to the future. At Pump Solutions Australasia, we are constantly tweaking and adjusting our product line to meet the demands of the present and future, but we never forget who we were or who we are.

We started in 1990 as Pumps and Services Australia. Originally, we developed hydraulic and vacuum solutions for many different industries, including mining, manufacturing, and fishing. We designed and custom-built an automated vacuum system that the Geraldton Fish Markets would use to vastly decrease the time it took for fish to be transported from the fishing vessel to the wharf to be processed.

In 2000, we decided to stop manufacturing pumps and take advantage of our connections with the finest manufacturers in the world, including elite German and Italian companies, to provide Australians with a wide range of the best pumps in the world.

Finally, in 2008, we would become Pump Solutions Australasia. And now, we are Australia’s leading wholesalers and distributors of residential, commercial, and industrial pumps. We carry an incredible range of pumps for every situation and every need, from small residential buildings to large factories to large water processing facilities.

Two of our popular brands are Fluid-o-Tech and Grundfos. We’d like to tell you about a few changes and new products from both companies. Just as we are tweaking and adjusting our product lines, so are the great manufacturers. Fluid-o-Tech and Grundfos are always on the cutting edge of technological advances.

We’ll start with Fluid-o-Tech. Last year, Fluid-o-Tech changed the profile on their PO/PA 70-400 series pumps. They used to be built with the classic, finned profile, but they are now built with a completely smooth profile. Fluid-o-Tech had already adjusted the rest of their pumps to smoother, sleeker profiles to improve efficiency and aesthetics. The PO/PA 70-400 series is the latest in their product line to undergo this change for the better.

Building on the success of the first generation of their TMFR and TSFR lines, Fluid-o-Tech has produced a second generation of the entire TMFR and TSFR product lines. The first generation was an evolution in the industry, as it integrated a magnetic drive rotary vane pump with what would turn out to be a brilliant improvement: a DC brushless variable speed drive.

Since Fluid-o-Tech refuses to ever rest on their laurels, they have improved the line again for the second generation models, to optimise the series for every possible condition. New changes include a more versatile electronic controller, a lighter and more efficient motor, an external control board, and a wider speed range. The TMFR and TSFR can now adapt to changes in the pressure or temperature of their immediate environments.

Grundfos has also been busy. They introduced the new, Renewable Solar Inverter, which allows pump and pumping stations to operate with nothing but solar power. This allows Grundfos to design and build pumps for situations involving the transport of extremely large amounts of water. Since their pumps can now run on solar power, they can also be installed in more isolated situations, and can be used for the largest jobs in the country.

Since the price of solar panels has gone down over the years, due to increased demand and more efficient production, Grundfos pumps can provide efficient but reasonably-priced solutions to nearly every need.

Grundfos also announced the new range of high-performing axial flow pumps with a feature called the “Unique Turbulence Optimiser.” The line is called the KPL Axial-flow Propeller Pump. The KPL is an axial flow propeller pump that is designed to produce high flow at low head. It has a flow capacity as high as 700 m3/min at a head of up to 9m. It is designed for flood control, but is quite versatile, and can be used for any situation where a lot of water needs to be pumped.

Grundfos custom-builds each KPL pump to ensure cost-efficient performance, and encourages customers to talk to their engineers in the planning stages to ensure that the pump is optimised to each customer’s individual needs. Some projected uses besides flood control: drainage and irrigation, raw-water intake, use in water parks to circulate large quantities of water, filling or emptying reservoirs, and even treated sewage.

Grundfos guarantees high quality, and a product that is both effective and cost-effective. They consider it to be the best value for your money; they individually test and register each pump.

That’s it for now: Happy New Year.

A Simple Guide to Pumps: Part 1

We get a lot of questions about pumps. What kind of pump is right for the job? What is the difference between kinds of pumps? How do water pumps work? We’re going to give you a simple guide to some of the pumps we offer throughout Australia, and hope we can make your choices easier. If it doesn’t work, you can always feel free to call us or email us; we will be happy to recommend the right pump for the right job.

Vacuum Pumps

A vacuum pump works just like a shop-vac. It removes air to create a vacuum. This causes lower pressure in the space where the air was removed, and allows the higher-pressure air to rush in and fill the space created when the air was removed. The most popular vacuum pump is a positive displacement pump. Vacuum pumps are used more for applications that don’t involve water, but are sometimes used in sewage systems.

Centrifugal Pumps

A centrifugal pump moves water by converting rotational kinetic energy into hydro dynamics energy. The energy comes from a motor, and water enters an impeller, where it is accelerated to move outward through the pump to either a diffuser or a volute chamber, where it then leaves the pump. Centrifugal pumps are best used for water, but are often used for sewage, chemicals, slurries etc.

Rotary Vane Pumps

A rotary vane pump is classified as a positive-displacement pump. It has vanes which are mounted to a rotor inside of a cavity. The simple type has a circular rotor which rotates inside of a circular cavity. The centres are slightly offset, causing what is known as eccentricity. To make a long story short, they are often used for holding wood or other materials down on CNC Routers in the furniture industry.

Double Diaphragm Pumps

A double diaphragm pump, also known as an AODD, is classified as a positive displacement pump that uses two diaphragms made of thermoplastic, Teflon, or rubber, which work with a reciprocating action. They can be up to 97% efficient, are self-priming, and can handle viscous fluids. They can also handle solids and corrosive liquids. Most uses for this pump are industrial, but they are also used on the filters for fish tanks. Another interesting use is artificial hearts.

How a Peristaltic Pump Works

If “peristaltic pump” reminds you vaguely of school, it’s because you might have heard it in a high school biology class. Peristalsis is the process by which food gets from your mouth to the other end of your gastro-intestinal tract. A more visible example might be seeing time-lapse photography of a snake swallowing an object that is wider than he is.

In peristalsis, whatever is being moved is on the inside of a tube, and outside forces are squeezing the tube, starting at one end and moving to the other end. As it is in nature, so it is with a peristaltic pump.

A peristaltic pump is classified as a positive displacement pump, and is used to pump fluids. The tube is filled with product, and a rotor with rollers, “wipers” or “shoes,” turns, causing the rollers to compress the tube at one end. Just like the biological example we used, the fluid is forced to the other end and finally out of the tube. Similar to squeezing a tube of toothpaste.

When the fluid is displaced, it causes a vacuum, and product is drawn in behind the rollers to refill the tube. This is often called “resilience” or “restitution.” The cycle starts over again for as long as there is fluid to pump and the rotor turns.

A popular application for a peristaltic pump is when sanitation is at a premium. Because neither the rotor nor the rollers touches the inside of the tube, there is less chance of any outside parts cross-contaminating the contents of the tube. Medical applications include pumping IV fluids and circulating blood through a heart-lung machine during heart bypass surgery.

It is also used for aggressive chemicals and other instances where the environment needs to be protected from the fluids, or where the fluid or sludge needs to be protected from the environment.   Due to their design, they are often the first choice for pumping viscous fluids or abrasives.

This means that there are no pressurised seals or O-rings to worry about. The only major design concern is that the tubing has to be elastomeric to maintain the integrity of the circular cross sections after repeated and prolonged use.

Besides being difficult to contaminate, peristaltic pumps are also extremely low-maintenance, and no backflow or check valve is needed to prevent siphoning.

Quick Guide to Pumping from Shallow Streams

Pumping a Shallow StreamWhen pumping, it is sometimes necessary to draw water from a shallow source, such as a small stream. In these cases, it can be difficult to successfully uptake the water because there is not enough depth to lay the pump into without causing difficulties. With the right techniques however, this process can be made much easier and run more efficiently.

Level and Depth

In any kind of water pumping project, the pump must be at a certain depth into the water for it to run effectively. It should be submerged at just the right level, usually a mid-level, where it is not too close to either the surface or the bottom of the body of water. This way, it does not collect sediment from the bottom or cause a vortex at the top that will create problems for the pump.

The pump should be above the bottom by at least half of the diameter of the pipe and it must be submerged at a similar correlation. The problem comes in when there is not enough depth to the body of water to allow for these specifications, in which case, special techniques must be employed.

Different Arrangements

To allow your pump to draw water from a shallow stream, you will need to use different techniques. One such is to create a small well that deepens the bed of the stream, thus giving you more room. Another technique involves placing a cover just above the intake to prevent it from drawing in air and creating a vortex.

You can also position the pump deep into the stream bed and place a filter around it to prevent sediment from getting sucked in. Some create a well adjacent to the stream and filter water into it, but these methods can be more costly.

Shallow Thinking

Pumping water from a shallow stream can be frustrating if you do not employ the right techniques. The pump has to be placed at just the right point to avoid complications but shallow bodies of water sometimes hinder this. Under such circumstances, altering the landscape around the stream to allow filtration or using additional devices can help you get around the process.
