The paper will present a new pulsation reduction system (PRS) invented by MHWirth. This PRS is in contrast to conventional pulsation damperssuitable to eliminate high-frequency pulsation of reciprocating diaphragm pumps. Brief description of functionality: The new damper is connected to the propelling fluid chamber of the diaphragms. The propelling fluid, a hydraulic oil, is used as a damping medium, converting the pulsation energy described above into heat by throttle effects. This effect is similar to a shock absorber. The paper will also explain the PRS effects, present operational data from field application and address the following benefits by using it in a tailings and storage facility:
This website links to the ICMM Member Companies and their disclosures related to a Church of England request. From the page: The Church of England Pensions Board and the Council on Ethics of the Swedish National Pension Funds wrote to 683 extractive companies, including ICMMs company members, asking them to disclose details of their tailings storage facilities. ICMM is supportive of greater transparency on this important issue. Members have responded to this request and have published details of the tailings storage facilities that they own or operate on their websites. Links are provided for each participating company, where site- and company-specific information can be found
