Technical Paper: API 676 compliance of progressive cavity pumps

Friday, August 3rd, 2018 von admin

Owing to their operating principle and their roots in waste water treatment, Progressive Cavity Pumps (PCP) come with typical deviations against petrochemical standard API 676. Some of these deviations are inevitable, others can be healed. It is a preservative headache and topic of discussion for project engineers to understand and identify which of these deviations are relevant, critical or acceptable for their project.

AODD pump with detachable mounting foot

Tuesday, July 31st, 2018 von admin

The new 6 mm (1/4”) Velocity Series AODD pump offers a detachable mounting foot providing adaptable mounting capabilities. Thanks to this design, the Wilden Velocity Series pump can quickly and easily be reoriented by loosening a single screw.

This design provides the user with multiple mounting options while allowing the pump to perfectly fit into restricted spaces, a critical consideration for OEM systems and skids.

New hygienic container pump

Monday, July 30th, 2018 von admin

For the production of cosmetics and pharmaceutical products as well as for the processing of foodstuffs, a special thoroughness and cleanliness must be ensured to consumers. When using hygienic pumps, the operator expects besides a high system availability and low maintenance requirement an absolutely perfect hygienic and easy to clean design.

The B70V SanitaryPlus barrel pump has a one-piece joint-free drive shaft and is consistently without threads in the hydraulic area. Just a few components reduce the assembly and dismantling times for approx. 80 % as well significantly reduce the cleaning effort.

Improved Bluetooth Monitoring Solution

Friday, July 27th, 2018 von admin

The i-Alert2 sensor upgrade improves

  • battery performance,
  • enable programmable monitoring intervals to detect faster transient fault conditions,
  • and expand monitoring coverage to large slow-speed pumps.

“These continuous improvements and portfolio expansion, driven by our users’ feedback, provide customers greater flexibility when using our state-of-the-art Bluetooth monitoring solution,” said David Malinas, President of ITT Industrial Process.

Centrifugal Pump Minute

Friday, July 27th, 2018 von admin

Griswold has developed an educational video blog called the “Centrifugal Pump Minute.”

The first video is about Determining available system NPSHA. James Farley, Griswold Product Manager, reviews how to determine available system NPSHA for a pump that is installed and operational. Using the calculation needed to determine NPSHA, James presents example tests that will establish system performance and possible pump cavitation.

Centrifugal Pumps in the production of frozen bakery products

Tuesday, July 24th, 2018 von admin

Technical paper by Susanne Suttrop

Committed to their slogan – Coppenrath & Wiese – Where else can you get quality like this? –  the company has earned a reputation in the field of frozen desserts that has been solidly anchored in the consciousness of consumers for more than 40 years (Fig. 1). But a slogan alone is not enough to satisfy customers if not simultaneously associated with reliably high quality products. That is why the company insists not only on high quality, fresh ingredients and skilled, talented employees but advanced production processes as well.

With a daily production volume of 3.3 million rolls as well as more than 200,000 various tortes, failure of even one component can lead to significant financial losses. For this reason, the company’s expectations for high-quality production systems are just as high as the expectations of consumers for outstanding products.

AODD pumps with a solid plastic design

Friday, July 20th, 2018 von admin

The new C-Series pumps have been specifically developed by Almatec to be a cost-effective alternative. The housing parts are tightened to each other via housing bolts. All of the C-Series’ bolts are tightened together against a diaphragm-sized ring on each side of the pump.

This design distributes the forces of the housing bolts onto the housing parts evenly, providing a consistent flow of forces that increases bolt torque and improves pump safety.

Technical Paper: High-performance carbon – the service life extender for pumps

Thursday, July 19th, 2018 von admin

Slides assume the main job of generating the vacuum – more than 30,000 hours of durability were achieved using a new material

Whether slide bearings, sliders or mechanical seals – all these components are exposed to high loads on a daily basis and, therefore, wear out. With innovative materials, however, maintenance intervals and the service life of pumps and seals can be extended considerably, as evidenced by developments in carbon materials.

Selecting the right material determines the service life of machines, units, and systems. Conventional materials often reach their load capacity limits, especially in pumps and mechanical seals. Schunk Carbon Technology develops and produces materials for seal rings, slide bearings, and pump components made of carbon and silicon carbide. These innovative materials particularly excel in the areas of abrasion resistance, sliding capability, media resistance, and temperature resistance. Carbon in the form of graphite also has the characteristic property of self-lubrication. All in all, exactly the features required in demanding industrial environments. “In practice, their use leads to a significant increase in service life and extended service intervals,” says Thomas Kräuter, Sales Director of the Mechanical Carbon Industry at Schunk. It is not enough to simply replace a material; many years of expertise are required. Three current development projects demonstrate the path from material to functioning components, leading to new materials that considerably extend the service life of pumps, seals and the like.

Downhole progressing cavity pump with submersible drive

Thursday, July 12th, 2018 von admin

A German energy supplier had initially used a geological horizon for gas storage, but then decided to extract crude oil from the same deposit. Therefore, a suitable extraction system had to be acquired for transporting the multi-phase mixture with a high gas content to the surface from 1,200 m below. Due to the extreme conditions, a special pump technology was required:

Netzsch developed a progressing cavity pump system with submersible drive. As all moving parts are positioned deep down in the well, there is also no risk of environmental impact from leaks at the surface. (more…)

Slurry test rig for pump optimizing

Tuesday, June 26th, 2018 von admin

Pumping of extremely abrasive media, e.g. mixtures of iron ore and water, poses major challenges to mine operators all over the world. In order to improve lifetime and increase MTBF (Mean Time Between Failure) values, reliable and well-proven technological concepts are required, especially in terms of wearing part resistance. The Mulitsafe double hose-diaphragm pump offers a proven technology for these highly abrasive applications. The only real wearing parts of this pump are the suction and discharge valves. To guarantee continuous improvement of the already high valve lifetime, a special test rig has been installed at the Feluwa works in Mürlenbach/Germany. Daniel Nägel and Philipp Werhan are describing, how this test rig (Fig. 1 – with pump type TGK 250 3 DS 35, performance data: Q = 14 m³/h, p = 130 bar(g) ) allows testing of customer-specific media under real conditions.
