  • VFD for pumping systems

    Pumping systems account for nearly 20% of the world's electrical energy usage. In some process plants, the VFD for pumps and fans together account for between 50% and 80% of the total electricity used. Very rarely have I come across pumps operating with fully open discharge valves. The same is the case for fans with dampers. ...

  • Pump Protection - unattended operation in sludge pumping

    Pulsar's 500 series non-invasive flow switches are used to great effect in this application, protecting sludge pumps and allowing unattended operation. Pulsar’s Pulsarguard 500 units are used by Whale Tankers to ensure that their specialist positive displacement pumps never run dry. By employing the Pulsarguard unit, staff are able to allow the pumps to operate unattended, confident that there ...

  • Replacement of Expensive Groundwater Pump and Treat System Pump and Treat System with Bioremediation

    Introduction Prior operations at a former Microwave electronics facility inSunnyvale, California, resulted in tetrachloroethene (PCE), trichloroethene ( TCE), cis-1,2-dichloroethene (DCE) and vinyl chloride (VC) impacts to soil and groundwater. In 1985, a groundwater pump and treat (P&T) system was implemented to address groundwater impacts. In 1996, CDM began ...

  • Development of Operation Navigation System

    ABSTRACTBureau of Tokyo Sewerage has 13 wastewater treatment plants and 82 pumping stations. In order to manage these facilities efficiently, collective operation in each treatment area is being promoted by making use of remote-control system. Promotion of remote control system leads to concentration of facilities monitored or controlled from the master facility, and, therefore, increases tasks ...

  • Performances of photovoltaic water pumping systems: a case study

    This paper presents a mathematical motor-pump model for photovoltaic (PV) applications which allow us to contribute in the studies of PV pumping sizing. The modelled motor-pump characteristic is flow rate-power (Q, P). The model is established for centrifugal pump (CP) coupled to DC motor. The non-linear relation between flow rate and solar power has been obtained experimentally in a first step ...
