New Self-Priming, Sealless Magnetically Driven Thermoplastic Pumps

Chemical Online brings a news release of Vanton Pump & Equipment Corp:

This new VANTON line of heavy duty self-priming, magnetically driven horizontal end suction centrifugal pumps is provided with all fluid contact structural components molded from solid homogeneous thermoplastics such as polypropylene (P) and polyvinylidene fluoride (PVDF).

Unlike metals, nonmetallic materials do not corrode. In addition to their chemical inertness, the thermoplastics also offer superior abrasion resistance. These are not plastic-lined metal pumps. Vanton self-priming PG/CGM magnetically driven pumps are constructed with thick-sectioned, solid thermoplastic components that provide a greater degree of performance reliability, reduce maintenance costs, extend pump life and minimize downtime.

These magnetically driven self-priming thermoplastic pumps are recommended for use at temperatures to 275÷F, for flows from 5 to 175gpm at heads to 175 feet. Their unique integrally molded thermoplastic priming chamber and check valve construction maintains the prime during fluid flow interruptions, as well as when the system is shut down for standard maintenance. The pumps offer the following additional advantages:

- Dual nonmetallic containment can assembly with fluoropolymer inner can assembly backed by a rigid nonmetallic composite outer can. This construction avoids troublesome eddy currents and enhances efficiency.
- Teflon sleeve assembly that completely isolates the large diameter stainless steel shaft from the fluid.
- High performance permanent rare earth magnets with power ratings to 45 hp.
- Dynamically balanced closed vane thermoplastic impellers with molded-in stainless steel inserts.
- Wide-open fluid passages that provide for fresh liquid cooling and lubricating of the bearings, and inner magnet assembly.
- Suction port designed to allow for rotation.

RM6 Mln For Repairs To Water Treatment Plants In Three Flood-hit States reports from Malaysia that the National Water Service Commission (SPAN) has estimated RM6 million for repairs to the water treatment plants as well as water pumps and intake pumps damaged by the recent floods in Pahang, Kelantan and Johor.

Its executive director Lee Koon Yew said of the total, RM3.5 million would be for Pahang, RM2 million for Johor and RM500,000 for Kelantan. He said the estimates were based on the extent of the damage to the water pumps which were submerged in floodwaters, and the intake pumps which were covered by sand, as well as for drilling works.

"Another estimated RM12 million will be needed to repair and upgrade the equipment of the Water Supply Department (JBA) nationwide," he told reporters after surveying the water treatment plant in Kampung Lubuk Kawah here today.

Lee said to avoid further damage to water infrastructure in future, a thorough study would be carried out before implementing any of the projects.Meanwhile, the Pahang JBA has assured residents that the state's water supply would return to normal by next week.

Its director Datuk Ismail Mohd Nor said the department, with the assistance of the army, Syarikat Bekalan Air Selangor (Syabas) and Puncak Niaga Holdings Berhad, was working round the clock to ensure that the 200,000 residents affected by the floods would be able to get back their water supply.

He said among the water treatment plants affected by the floods were at Sungai Bera, Chenor, Simpang Jengka, Pekan Tajau in Maran and Lubuk Kawah here. However, he said the plants in Chenor, Simpang Jengka and Pekan Tajau were now operational and able to supply water to some 80,000 residents in Maran since two days ago.

Republic Services outlines new timetable at Pike Township dump in note to Ohio EPA

Bob Downing reports at, the official website of the Akron Beacon, on the installation of new pumps to remove excess water from a troubled landfill in Stark County, which is expected to be completed by mid-February:

Building two relief wells will likely take until Feb. 29, said Florida-based Republic Services Inc., the parent company of Countywide Recycling & Disposal Facility in Pike Township.
The revised timetable is outlined in a recent letter from Republic Services to the Ohio Environmental Protection Agency.

The timetable is expected to be part of new findings and orders from Ohio EPA Director Chris Korleski. The schedule was worked out between the company and the agency in two weeks of meetings about the fires and odors from the 258-acre landfill.

The initial EPA order called for the work to be completed by early December. However, the company needed more time. The latest plan calls for installing 37 additional dewatering pumps, along with related infrastructure, by Feb. 15, the company said.

In addition, new air compressors will be installed by Jan. 31 and two relief wells by Feb. 29, the company said.

Winter weather could affect that schedule, but the company will do its best to comply, said Clarke M. Lundell, the company's director of engineering.

The EPA in November had issued findings and orders, but those deadlines need to be revised.
The EPA said landfill fluids which may be contributing to the chemical reactions and fires are accumulating faster than expected, affecting the ability of gas extraction wells to do their job and slowing the process of liquid removal. The fluids also make the landfill less stable.

The agency said the landfill will produce about 25 million gallons of liquid runoff this year.
The chemical-laced liquid is hauled to sewage plants in northern Ohio for treatment and disposal.

Removing the excess liquid was ordered by EPA Director Chris Korleski as an initial step to extinguish the fires and as a way to slow the chemical reaction between the liquid and buried aluminum wastes.

Pumping off the excess liquid would help dry out and cool the landfill, the EPA said.
What happens after the liquids finally are removed will help shape the final remedy for the landfill, officials said.

The EPA could require Republic Services to cap the affected area with synthetic liners and install additional gas-extraction wells until the landfill is fully stabilized. That approach is preferred by the company, although it could take up to six years to be fully implemented.
Another option would be to order the company to excavate the landfill or a portion of it.

That would be a costly, time-consuming and risky proposition that would create big odor problems. Such a remedy might take two to seven years. In a related development, Republic Services last week released a report that it says shows temperatures dropping within the landfill.

That is evidence that the fires are ''under control and beginning to subside,'' the company said in a statement.

The evidence comes in the form of up to 250 temperature readings from gas-extraction wells within the landfill, especially the 88-acre tract where the fires and odor problems originated.

The trend over the last six months is a slight lowering in temperatures from 194 degrees to 190 degrees, said senior program manager Michael Beaudoin of Earth Tech Inc., a consulting firm.
That trend ''could indicate a lessoning of the reaction in the landfill,'' he said. ''This means the measures we are taking to remediate the landfill are working.''

Normal internal landfill temperatures run from 110 to 150 degrees. The highest temperature at Countywide is 240 degrees, the company said.

New Dry Vacuum Pump System Helps Producers Reduce Energy Costs and Improve Product Quality

ThomasNet brings a news release of Edwards (formely BOC Edwards) from Wilmington, MA. The company reports on a new mechanical oil-free vacuum system for degassing steel alloys, which offers dramatic savings in energy costs of more than 90% compared to traditional steam ejector systems.

Steel producers, and those making specialist alloys for aerospace and other applications, will find that the Edwards vacuum system could play a significant role in helping them reduce their carbon footprint. It is being launched, ahead of January 2008 when Phase II of the EU Energy Trading Scheme (Directive 2003/87/EC2) comes into force.

Under Phase ll the scope of the scheme is to be expanded to include all greenhouse gases, not just CO2 as now. Companies running energy intensive processes may well find themselves liable for significantly increased 'offsetting' costs as a result.

Vacuum degassing (VD) and vacuum oxygen decarburisation (VOD) are used in the production of speciality steel alloys to reduce the levels of hydrogen, carbon and other impurities during the secondary steel making process.

Traditionally producers have used large, energy-hungry multi-stage steam ejector systems, backed with liquid ring pumps. Such systems not only require consistent high quality steam, but can also suffer from fore-line dust deposits that develop into "cakes" making cleaning difficult.

The new dry pumping system from Edwards consists of HV30000, SN7000 and IDX1000 pumps arranged in three stages, pre-mounted, piped and fully wired on a two-part skid. Each skid is nominally capable of vacuum degassing around 23 tonnes of steel, so a number of skids can be mounted in parallel and integrated with the steel degassing tank to suit the required ladle size, typically up to 160 tonnes or more.

The oil-free vacuum pumps are ideally suited to pumping the off-gas mixture containing traces of metal and refractory dusts normally found in these processes.

The pumps are selected for each stage from Edwards' wide range of vacuum equipment and combined to make a system which is fully optimised to the pumping speed and compression requirements of the application. The result is a robust, high efficiency, expandable, modular design, easy to install and operate in typical steel degassing environments.

The energy costs associated with running the new system have been shown to be less than 10% of that for a steam ejector system in both VD and VOD applications. Further, quality of the final product is improved by using dry pumps.

Residual hydrogen is reduced because the back-streaming effect associated with steam ejector systems is eliminated, and because evacuation is faster, closer control of the chemistry is possible. As a result, manufacturers will be able to produce more consistent formulations, and to optimise their products for more specialist applications.

Other operational benefits include reduced maintenance, and easier cleaning and waste disposal.

'Smart' Diaphragm for Signal Metering Pumps from Gee & Company

A news release from Gee & Company on a 'smart' diaphragm for signal metering pumps:

Improved operational safety and higher volumetric efficiency are among the benefits achieved by the introduction of new smart diaphragm technology to some of the heavy-duty dosing pumps in the Signal range.

The essence of the smart diaphragm is that it empowers the pump itself to decide when and how much oil is to be replenished. This process ensures that any hydraulic oil that is lost in normal operation - through the air bleed valve or via the built-in relief valve - is not only restored just when it is needed, but also in exactly the required quantity.

Claimed to be much more precise than less sophisticated replenishment systems, it avoids oil overfeeding as well as potential problems related to unexpected suction conditions that could lead to diaphragm rupture.

Now a standard feature on all models in the Signal S300 X range of spring-return and hydraulic diaphragm pumps, smart diaphragm technology is claimed to take operational safety to even higher thresholds. It ensures high volumetric efficiency at all stroke and pressure settings and is particularly effective at minimal operating pressures of below 1 bar.

With applications in the potable water, effluent treatment and industrial markets, these heavy-duty process pumps are able to operate continuously across a range of high performance and safety-critical applications. They partner other pumps in the Signal S300 series that feature such features as API 765 casings and double-diaphragms for inherent safety.
