Is the Grundfos S-tube the Wastewater Pump of the Future?

Waste Water PlantWe have seen a lot of water pumps over the years, and most of them fall into distinct categories. Grundfos, however, now offers a pump that is in its own category. It is called the S-tube. The S-Tube is designed for wastewater processing, and combines the designs of a few different types of pump to create a unique product.

Grundfos created the S-tube as a response to a typical and prevalent wastewater industry problem. Most pumps in the industry either sacrifice free passage or high efficiency. This means that they sacrifice either efficiency or reliable operation.

The S-tube is designed to provide both efficiency and reliable operation in one design solution. In today’s era of water shortages, it is essential that communities process their wastewater both efficiently and reliably. The S-tube provides both options. This allows water companies to provide enough water for their communities without increasing operating costs.

Without getting too technical, the S-tube has a closed impeller and unique design that allows high efficiency and free passage. In addition, the S-tube employs the Grundfos blueflux motor design, which is very energy-efficient. Grundfos has been able to get an advance look of what they project to be future efficiency requirements for water treatment plants, and the S-tube meets or exceeds all projected requirements.

The S-tube is also very easy to service. Thanks to AUTOADAPT, which is an “intelligent” module that adjusts operation to whatever condition it encounters, wastewater treatment plant personnel don’t even have to make any adjustments when conditions change. All they have to do is turn it on once, and operation is on autopilot for the life of the pump.

Grundfos has designed the S-tube to adapt to a variety of wastewater treatment applications, and fully intends for their product to, indeed, be the wastewater pump of the future.

In Perth, WA, and across Australia, years of hot, dry weather, have produced water shortages and watering restrictions. As in other parts of the world, processing rainwater and wastewater are becoming more essential to Australian life with each passing year.

We’re proud to carry Grundfos’ line of innovative products. Call 1300 922 973 to learn more.

Verderflex Peristaltic Pumps Repair Mining Damage to Water

Peristaltic pumps are important to the mining industry. In South Africa, they are playing a major role in rebalancing the pH of water in and around the mines. South Africa is a different situation than WA, but it does serve as a warning for what can happen here in WA if the mining industry isn’t careful.

MiningIn South Africa, there hasn’t traditionally been a lot of regulation in the mining industry. Consequently, years and years of unregulated activity has caused the acidity of water in South African mines to increase by unprecedented levels. The situation has escalated to a point where it could have a serious effect on the population around the mines.

So, what does South Africa’s mining industry have to do with us here in Perth? Their situation should serve as a cautionary tale for our own mining industry here in WA. Our mining boom is only a few years old, and our safety regulations are much better here, but it is never too early to start looking out for our future.

For the mining industry, it means that they can use South Africa’s situation to peek into the future and help them to eliminate any potential problems before they become big enough to cost them serious money. Acid Mine Drainage (AMD) is a serious problem in South Africa, and it can affect crops and quality of water, resulting in less production and a loss of farming jobs.

Dosing Lime with Peristaltic Pumps

South Africa’s CSIR, which stands for Council for Scientific and Industrial Research, has developed a process they call the Alkali-Barium-Calcium (ABC) Process. First, lime and/or CaS are pre-treated. Then, sulphate is removed using Barium treatment. Then, the sludge is processed.

Verderflex peristaltic pumps are used for the treatment. They move the fluids by using positive displacement inside of a flexible hose, pushed by an external “shoe” in a circular motion. With this kind of pumping, the high viscosity of sludge never causes the pump to clog, and the fluid never touches any of the moving parts.

Processing with a peristaltic pump is reliable, energy-efficient, and eliminates the chance of cross-contamination.

Manufacturer Spotlight: RAN Double Diaphragm Pumps

We import water pumps from all over the world into Australia. RAN pumps are made in Istanbul, Turkey, and sold on every continent. They specialise in diaphragm pumps, and manufacture both air operated and electro-mechanical diaphragm pumps.

Diaphragm pumps are used in many industries, such as food, alcohol, wastewater, petrochemical, chemical, petrol, pulping, paper, and filter press and of course the mining industry. RAN pumps are all proprietary designs, and manufactured by the parent company, Gisan.

Diaphragm pumps work by moving a diaphragm to expand or contract the area of a chamber. Expanding the chamber lowers the pressure, allowing fluids to flow in. Contracting the chamber raises the pressure, forcing fluids to flow out. The action is similar to a cylinder in the engine of your car.

Diaphragm pumps have good suction lift capability, and can be used to pump slurries and sludges that have a high solid content. They can provide discharge pressure as high as 12 bar. Their use runs from large industrial pumps to small pumps in artificial hearts or fish tanks.

Diaphragm pumps are self-priming, and provide up to 97% efficiency. Small diaphragm pumps are even used as air compressors, due to being inexpensive, relatively quiet, and having limited moving parts within the air stream. This ensures that the air will be clean.

We carry eight different lines of RAN double diaphragm pumps: aluminium, plastic, food grade stainless steel, cast stainless steel, cast iron, PVDF (polyvinylidene fluoride), also available in electric driven, and high pressure pumps.

Our plastic pumps range from the AP, which is a ¼ inch polypropylene pump, to the FP, which is a 2 inch polypropylene pump. The aluminium pumps range from the BA, which is ½ inch, to the 3 inch GA. Food grade pumps range from the ½ inch BS to the 3 inch GS. The PVDF pump from BPV, measuring in at ½ inch to the 1”DPV. Cast iron pumps range from 1” DC Series to 3” GC Series. We also have a range of cast stainless steel pumps.

Our electric-driven pumps are available in plastic, aluminium, and stainless steel, in ranges from 1 inch to 3 inch. We carry two high pressure pumps: the 2 inch FHC, and the Hydraulic Piston Pump.

Whatever your need or application, Pump Solutions Australasia has the right pump for you. Call us on 1300 922 973 today, and tell us what you need. Our expert staff will find the best pump for your individual situation.

What do the Mining Industry, Wastewater Treatment, and a Good Cup of Coffee Have in Common?

The short answer: Verder peristaltic pumps. Western Australia has benefited greatly from the mining boom, and we have seen the movement of Verder peristaltic pumps go “off the charts” for mining applications. But slurry pumping for the mining industry is only one use for Verder peristaltic pumps. They are also quite popular in wastewater treatment plants and chemical pumping.

So, what about that cup of coffee? Even though the bulk of Verder’s inventory is large pumps for mining and water treatment applications, they also make pumps of all sizes, even as small as the little pump that moves the water in the coffee maker at your office or your favourite restaurant.

At Pump Solutions Australasia, we pride ourselves in importing the very best pumps from the very best companies across the globe. From Europe, we leave no stone unturned when it comes to finding the right pump for the right job.

Verder has manufactured and supplied pumps to the mining, water, food, pharmaceutical, chemical, and plastics industries for nearly 50 years. They have office and production facilities in Europe, the US, China, Japan, and South Africa. Their reputation is built mainly on peristaltic pumps.

Peristaltic pumps work like the swallowing mechanism of your GI tract. Water enters a tube, where a rotor pushes a roller, also called a shoe, lobe, or wiper, along the surface of the tube, pushing the water through as the tube is compressed.

For a better understanding, fill a straw with water and turn it upside down with your finger sealing the opening at the bottom. Then, squeeze your thumb and finger together on the bottom and move it upward, forcing the water out of the straw. This is what is done in a peristaltic pump, but it is done in a rotary motion. The rotating roller squeezes the tube against the pump casing, moving the fluid through the pump.

We currently carry the VF series, which is Verder’s original Verderflex peristaltic hose pump, and the Dura series, which combines the benefits of close coupled and long coupled pumps.

Wake of the Flood: The LH Series

When unexpected flooding strikes and you need the perfect pump to remove residual water, Pump Solutions Australasia is here with exactly what you need and the best pumps in Australia. Based in Perth in the western half of the country, we supply a variety of different pumps for any occasion including dewatering pumps for taking care of unforeseen flooding.

Among our different types of dewatering pumps, we have a few notable models that stand out. All of these types of pumps serve the same function, but the LH series pump stands out as one of the best. There are two main categories within the LH series of pumps.

The first is the general dewatering LH series. A three phase motor pump, this model is made from cast iron and is meant for high head water draining. The outward design of the pump allows for it to be operated in smaller spaces because it is cylindrical in shape and the discharge port is at the top of the pump. The constructional design of it also allows it to be installed truly to the centre of gravity. It can also be lifted and moved up or down without the need to disconnect the pump motor from the pipes.

The deepwell pre dewatering LH series is similar to the first, yet has one or two notable differences. It is larger than the former and can be submerged into deeper water or any flooded material. This is useful in circumstances that call for it, such as when the flooding is greater than usual and mine shafts.

Both of these series of models have a number of features with them to ensure maximum performance, an extra-long cable can be added if you should have need of it.

Pump Solutions Australasia takes great pride in its quality of pumps and offers the full backing of our talented staff if any problems should arise.

For more information and any questions you have on our dewatering pumps, especially the LH series, call us at 1300 922 973.
