Optimising pumping using variable speed drives

by Troy Leyden, Operations Engineer, Fitzroy River Water It is well known that a variable speed drive (VSD) can be used to reduce energy consumption by slowing down a pump instead of throttling a valve to deliver the desired flow rate. But what savings could be achieved if a VSD was installed? If a VSD […]

Meeting the system needs

by Ray Hardee, Chief Engineer, Engineered Software In this article, we will look at a wastewater collection system consisting of a pump, collection and destination tanks, and the interconnecting piping. In this system, water is pumped from a collection tank to the destination tank and a pump is required to overcome the change in static […]

Interaction of components in piping systems

by Ray Hardee, Chief Engineer, Engineered Software Piping systems are often called upon to deliver product or services that differ from their original design intent. The engineer is then tasked to make the required changes with minimum impact to production or service delivery with the smallest possible capital outlay. Sometimes what might seem to be a simple, straightforward […]

Thinking positive: the characteristics of positive displacement pumps

The PIA’s Australian Pump Technical Handbook is a cornerstone text for the Australian pump industry and, in our opinion, a must have for anyone who deals with pumps on a regular basis. In this ongoing series, we feature abridged chapters from the classic book to showcase the various areas covered and to reacquaint readers with the technical aspects […]

New pump training centre

Hydro Innovations recently opened a new training centre, called the Hydro Innovations Pump Institute, to assist its customers in the selection, troubleshooting and maintenance of centrifugal pumps. The centre will focus mostly on self priming pumps, but aspects of the curricula offered will also include standard centrifugal and submersible pumps. The institute covers two floors, […]

Controlling a piping system

by Ray Hardee, Chief Engineer, Engineered Software This is a continuation of a series of articles on understanding the operation of fluid piping systems. We previously discussed how a piping system consists of three elements working together to achieve the system’s objectives. The pump element adds energy to the fluid to overcome the static and dynamic head of […]

The importance of feed pump barrel inspections

by Greg James, Hydro Australia Rebuilding a typical boiler feed pump cartridge and returning the running clearances to specification is a critical process for effective and efficient plant operation. The cost to rebuild a cartridge – supply new mechanical seals, bearings and consumables, the lost production, down time and the labour costs – is a significant investment. After rebuilding […]
