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…)

Providing the best water in Karelia

Tuesday, July 10th, 2018 von admin

The Northwest of Russia literally flows with water. An area known for huge lakes and vast wetlands. Petrozavodsk is the capital, and the largest city, of the republic and most of the 300,000 inhabitants get their drinking water from the nearby Lake Onega. But some new settlements on the outskirts of the city have chosen another source. “We get our water supply from an aquafer, that covers most of southern Karelia. Three large pumps from Grundfos deliver water to our building complex with around 5,000 people,” explains Vitaliy Markov, General Manager of Drevlyanka Vlll – a part of Chistiy Gorod.

Pressure transmitters for remote commissioning of functional safety

Tuesday, July 3rd, 2018 von admin

Siemens presented Sitrans P320/420, the first pressure transmitter on the market to feature remote safety handling reducing commissioning time in applications requiring functional safety.

Via Simatic Process Device Manager (PDM) the safety integrity level (SIL) devices will be commissioned: rather than manually attending to each individual device across the facility, operators can commission transmitters from the control room. This next generation of pressure transmitters was developed according to IEC 61508 standard for the use in SIL 2/3.

Metal seated ball valves for up to 420 bar and 450 °C

Monday, July 2nd, 2018 von admin

The patented design of the so-called ‘Dissolution’ ball valve offers optimized distribution of forces and loads in the ball valve, so that they only occur where they are actually needed. This means that the ball valve made by AS-Schneider can be actuated easily even under high pressures up to 420 bar.

The forces needed to maintain the tightness between ball seat and valve body are only directed onto the corresponding graphite seal rings (see figure).

Hermetic deliver more than 200 pumps to the Middle East

Wednesday, June 27th, 2018 von admin

The Germany based pump manufacturer Hermetic dispatched more than 200 pumps with canned motor drive to the Middle East. The mega scale project includes all pump widths: from the smallest CAM 1 serie to typical oil & gas pumps of the CNP range. All of them are fitted with API 610 (American Petroleum Industry standard) hydraulics and equipped with a maintenance free canned motor. The drive power ranges from 1 kW to more than 100 kW.

The pumps fulfill API 685 standard requirements for sealless pumps, as well as expectations towards safety and reliability.

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.

AODD for hygienic processes and sanitary applications

Monday, June 25th, 2018 von admin

Flotronic’s ‘E’ Series pumps are air operated double diaphragm pumps (AODD). These pumps have proved themselves unmatched when tested to exacting performance standards by EHEDG (the European Hygienic Engineering & Design Group). The ‘E’ Series offers peace of mind for the food, beverage, dairy and pharmaceutical industries – and any environment or process where avoidance of product contamination is paramount.

The 10” version with 2” connections offers a pump solution ideal for customers with low to mid-range flow rate applications while customers seeking flow rates as high as 500 litres per minute will find the 12” pump with 1½” – 3” ideal.
