New CR series 3” and 4” tungsten carbide high head cutter pump produce heads of up to 70 metres.  Designed for cutting fibrous material in industrial or effluent/sewage applications, the new series was developed for applications where pump out either over longer distances or higher elevations is required.
“The new tungsten carbide high head cutter pump range is expected to be of real interest in sewage, effluent and industrial waste applications where more head is required than conventional equipment”, said Australian Pump Industries’ manager, Neil Bennett.  “The combination of the ability to chop material and pump to a high head is a new development,” he said.
The new three-phase CR series start from 2.2kW units that offer flows of up to 600 litres per minute with heads to 20 metres.  At the other end of the scale, the big 22kW 4” version delivers maximum flow of 1700 litres per minute with a head of 70 metres.
All submersible pumps are backed with a 3 year warranty. This is possible because they incorporate features that make them extremely robust and they are designed for an extended working life in severe conditions.

CR series incorporate a cutter mechanism that consists of a Tungsten carbide tip channel impeller and a saw-tooth suction cover hardened surface.  The cutter mechanism cuts fibrous material into small pieces permitting clog free pumping.
Like all sewage and wastewater pumps, the new CR series come with a unique anti-wicking cable entry.  This mechanism protects the motor by sealing the stripped back cable conductors with a moulded rubber or epoxy “potting” which has been loaded between each strand of the conductor.  This unique feature prevents wicking along the strands of the conductor itself and protects the motor.

The motors are dry type squirrel-cage induction design, housed in a water-tight casing.  They conform to insulation classes E or F.  In each of these insulation classes all standard pumps can be used in ambient temperatures of up to 40 degrees Celsius.
The CR series mechanical seal is a double silicone carbon style located inside an oil chamber.  The oil chamber, located beneath the pump chamber and the motor, prevents the ingress of water to the motor.  Tsurumi’s fully oil immersed mechanical seals eliminate spring failure caused by corrosion, abrasion or fouling.

The seal chamber is also fitted with a patented “oil lifter”.  This is a lubricating device for the mechanical seal.  It utilises the centrifugal force if the shaft seal by forcibly supplying lubricating oil to the mechanical seals.  This simple device protects both seals, lubricating and cooling but retaining stable shaft seal effect to extend life.
Pumps up to 7.5Kw have an auto cut out resetting CTP (Circle Thermal Protector).  This is integrated into the motor housing.  The CTP directly cuts the motor circuit if excessive heat builds up or an overcurrent caused by electrical or mechanical failure occurs.
Sliding discharge connectors are also available for the cutter pump range and are popular for permanent installations.  Pumps can be easily removed for maintenance without the need to drain the wastewater pond. The C series are available in a wide range of options from 50 through to 100mm discharge bores and with power ratings of between 0.75Kw to 15Kw.

Recently, according to the data released by National Development and Reform Commission, it is said that logistics costs was 10.8 trillion RMB in last year, accounting for 16.0% of GDP. Therefore, many cities have been introduced many policies for enterprises to reduce logistics costs, it is possible to significantly reduce the passage money of highway.

"2015 National Logistics Operational Aspect Briefing" shows that the total cost of social logistics is 10.8 trillion RMB in last year, an increase of 2.8% over the previous year, accounting for 16.0% of GDP. Vice Director of China Federation of Logistics and Purchasing Zhouzhi said that the current charge of highway accounts for 30% -40% of the main transport business costs. The member of the National Committee of CPPCC and the vice-chairman of All-China Federation of Industry and Commerce Xu Guanju said that if the logistics cost increases, it will become a stumbling block to the development of domestic manufacturing enterprises.

By reducing the passage money of highway would further reduce logistics costs, which will directly affect the development of tungsten enterprises. Tungsten heater is one of the main tungsten products, and highway transport is the most important way to transport goods. This year China's provinces began to reduce logistics costs and make the appropriate measures. Hubei province has been reduced the province's highway charge about 10% from June 1 this year, and Shanxi province introduced preferential policies by a wide margin for the trucks of highway from May 20.

These policies not only help reduce product transportation costs, but also allow truck drivers benefit from it. Many truck drivers said that reducing the passage cost of highway, they are able to save some of that money. While reducing the cost is conducive to the development of manufacturing enterprises, but the requirement of repair and maintenance to the highway would be stricter, and the increased of vehicular traffic is bound to increase the burden on the road.

According to the British Broadcasting Corporation (BBC) reported that on the local time on June 24, the referendum vote for Britain to leave the Europe has been counted, the results show that 52% of Britain citizen support to exit from Europe, which means that the UK will be out of the EU. Influenced by the referendum, the pound plummeted substantially, the euro and the dollar also fell more than three percent, while the Swiss franc, the Japanese yen is skyrocketed, this brexit directly burns the global currency market, in order to stabilize their economic, and there many countries has been intervene the national economic.

European a major place for cross-border imports as electricity suppliers, and it is an important export market for cross-border electricity supplier. But now the state of the economy of the whole Europe is in shock period, the pound and the euro will likely to depreciate for a long period, which benefits domestic tungsten enterprises for importing related equipment. In this way, domestic tungsten manufacturers can improve the quality and quantity of tungsten products (tungsten heater). But on the other hand, export becomes an issue. Business profits will decrease. The industry said that at present the most cross-border electricity supplier for China and European logistics companies (excluding postal operators) in China have a layout in the UK, a large proportion of shipments should be pass the UK into the EU (dedicated line, overseas warehouses, etc.) . Therefore, for those service providers, they will be more or less affected.

In fact, the United Kingdom and Europe are not ready to the follow-up work for brexit. Britain has little effect to core business of SprintPack in a short time, because the British and European countries need to establish the appropriate bilateral agreements. The global economy will be in a long grace period, countries should make the appropriate measures to stabilize their economies.

Although the WiFi technology has become increasingly popular, but there are still exist some problems. If there are a lot of people connect a WiFi at a time, the internet speed will be very slow, and the wireless signal would become instability. What’s more, not all of places install the wireless network. For its own drawbacks of WiFi, German physicist Herald Haas and his team of the University of Edinburgh invented a patented technology that uses a bunch of flash to transmit the wireless of digital information. This technique commonly refers to visible light communication (VLC). In this way, LED bulbs can quickly transmit binary encoding. But to the naked eye, this type of flashing is not visible, only the light-sensitive receiver can detect it.

Visible light communication technology, the nickname of Li-Fi is not just improving the coverage of the Internet. As the most important technology of wireless data transfer, WiFi use radio frequency signals. However, radio wave is only a small part of the entire electromagnetic spectrum. With demand of users of wireless internet is increasing, the available radio spectrum are increasingly less. For example, when people surf the internet in a cafe, if there are more and more people use the internet, people will find that speed is very slow, which is the same as the 3G mobile networks. At the same time, according to Cisco's data, the amount of information transmitted through mobile devices is doubled every year. Data transfer rate of LiFi network is up to 1GBps, which is 100 times as quick as WiFi.

Once this technology can be improved perfectly, this will be a milestone for network information technology. The accelerating of the transmission speed of the network will help domestic enterprises, such as tungsten communicates with foreign enterprises. And it benefits domestic enterprises to get more foreign tungsten market information, which will bring good economic benefits to the world's tungsten market (tungsten heater).

Our country plays an important role in cemented carbide industry around the world, which is one of the main countries of raw materials and manufacture. Tungsten carbide materials have many advantages, such as high hardness, high strength, good thermal-setting, excellent wear and corrosion resistance and so on, which have been widely used in modern machining tools, wear-resistant materials, corrosion-resistant and high-temperature materials, etc, especially indispensable in tungsten carbide cutting tools. Development status and problems of cemented carbide industry in our country, mainly in three aspects: total production of large, relatively low profit margin; carbide products lack comprehensive export channels; related business technology innovation development is insufficient.

Although China in terms of production of cemented carbide is far ahead in the world, but at the margin is far lower than other developed countries. The main reason is that the domestic carbide products are mainly concentrated in the low-end products; the low degree of processing, low-tech, value-added products is not high, supporting the poor, such as the number of bars, plates and so on. While foreign enterprises focus on high-performance, high-precision and high-end CNC inserts, micro drills as well as some parts of precision instrument, so the profit is dramatically increasing. In terms of export channels, our carbide products export channels the vast majority still remain in the traditional way of wholesalers and retailers a simple intermediate channels. Each member of the channel as an independent economic entity, it will be in order to maximize their own profits, difficult to form a benefit-sharing, risk-sharing marketing model. Therefore, we should adopt multi-channel marketing management according to different carbide industries; design reasonable, flexible product pricing mechanism, keeping the right balance of sales channels; Improve information management of sales channels, improve the efficiency of distribution channels, establish direct marketing system, carbide production enterprises.
