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.

Hermetically sealed Twin-Screw Pump for chemical and petrochemical sectors

Monday, June 18th, 2018 von admin

ITT Bornemann launched a new hermetically-sealed pump, named SLW, at Achema 2018 in Frankfurt, Germany. This pump serie uses a magnetic coupling for a hermetic pump drive. With the sealed fluid chamber, critical media with harmful substances are confined to the pump and not released into the environment.

  • The design allows the two screws to convey the product and transmit the torque.
  • The single-volute design is also compact and requires a small footprint for installation.
  • The product is lubricated with inboard bearings.
  • The less-wear parts design leads to low-maintenance, resulting in high MTBF.

Hermetic: 1 meter shaft = 15 meters immersion depth

Thursday, January 26th, 2017 von admin

As a replacement to conventional submersible pumps, the manufacturer Hermetic supplied two 8-stage, sealless canned motor pumps. The distinctive feature of the transformation was the customized adaptation of the pumps to the existing plant and its vessels. The pumps were designed for easy installation in the existing tank (with a diameter of 500 mm). The customer, a Swiss fine chemicals manufacturer, thus saves the costly, time-consuming conversion of the existing systems in its production plant.
