Centrifugal pumps Centrifugal pumps are a type of rotodynamic pump which uses a shaft-mounted impeller that rotates unidirectionally within the pump casing. These pumps can be subdivided based on the type of impeller used: Axial flow pumps Axial flow pumps (sometimes also known as propeller pumps) use an impeller typically driven by an electric motor […]
Beyondie SOP Project reaches half-way milestone The Beyondie Sulphate of Potash Project (BSOPP) is over half-way to completion and tracking ahead of its updated schedule. During July, construction started on the SOP Processing Plant with the mobilisation of DRA to commence civil and concrete works and installation of underground services. Following completion of the recent

Bryn Estyn Water Treatment Plant upgrade progresses to next phase of works TasWater’s largest water treatment plant upgrade is gaining momentum, with the next phase of works underway at the Bryn Estyn Water Treatment Plant (WTP). The upgrade has been designed to bolster water supply security for Hobart residents and those in surrounding suburbs. Ian

Rotary pumps Rotary pumps are a type of positive displacement pump where for each revolution, a fixed volume of fluid is moved. These pumps are self-priming and provide near constant delivered capacity no matter the pressure. These pumps are designed with very small clearances between its rotating and stationary parts in order to minimise leakage
Positive displacement pumps Positive displacements pumps is a broad category of pump, consisting of rotary and reciprocating type pumps, and is the second most popular type of pump after centrifugal pumps. These pumps move fluid at a steady rate and pressurise it to allow it to pass through a system by drawing the fluid into

Reciprocating pumps Reciprocating pumps are a type of positive displacement pump which use alternating force and suction – using a piston or diaphragm – to create a steady, pulsing flow, with one or more check valves to regulate and direct flow through the system. The pump chamber is repeatedly expanded and contracted to draw the

Pressure pumps Pressure pumps are designed to enhance the pressure and flow of water to allow larger volumes to flow through a water system when the water supply pressure is inadequate for the application. These pumps use a piston or plunger, located inside a cylinder, to apply force on the water, fluid or liquid that
Rotodynamic pumps Rotodynamic pumps are one of the two major categories that most pumps fit into. These types of pumps are kinetic machines where energy is transferred to the pumped fluid via a rotating element, such as an impeller, propeller or rotor. The mechanical energy is transferred to the fluid primarily by increasing fluid kinetic
Transfer pumps Transfer pumps are used to move any kind of liquid from one place to another. They are commonly used in applications such as processing, water purification, desalination and liquid handling, with some designed to be used for heat transfer, fluid flow, or transporting a heat transfer fluid or coolant. There are many types
Submersible pumps Submersible pumps are designed to be either fully or partially submerged in water. They can be operated this way due to the motor being hermetically sealed and close-coupled to the body, allowing the pump to be submerged in fluids without the motor being compromised. Instead of pulling the water to the surface, as
