Pump field services

Friday, February 2nd, 2018 von admin

Large pumps, such as those operated in the

  • oil and gas,
  • power generation and
  • water industries

perform a crucial role and represent a significant investment by the owner. Safeguarding these assets and maintaining efficiency and reliability are vital for the continued productivity of the application. Very often, when it comes to maintenance, the choice is between the original equipment manufacturer (OEM) or an independent service provider (ISP), but John Murray describes here that it is possible to have the best of both worlds.

What To Consider When Selecting a Filter-Press Pump

Technical paper by Peter Schüten:

High-Pressure Air-Operated Double-Diaphragm (AODD) Pumps Deliver The Operational Advantages Necessary For Optimized Operation Of Chamber Filter Presses.

In many industrial processes that feature the handling of liquids, the substances that are being transferred may occur in an aqueous or “muddy” state, with the liquid portion needing to be removed. This liquid-removal stage may take place during the production process – for example, in the filtration of edible oils or yeast solutions – but it more frequently occurs at the end of a process like wastewater treatment when the waste sludge that has formed must be withdrawn. Since the disposal of such sludges is calculated based on weight and volume, their thickening and drying is particularly lucrative for the processor. During the thickening and drying process, the sludges are treated using chemicals and/or physical processes so that the waste sludge forms into flake-like solids. After adjusting the pH level to neutral or alkaline via the use of milk of lime, the subsequent dewatering process separates the water for disposal, with the remaining volume of sludge significantly reduced.

The simplest technology for this process involves collection and thickening of the sludge through the use of gravity. However, it is significantly more effective to use technical drying methods via processes such as centrifuges and evaporators, or more commonly, chamber filter presses (Fig. 1).
