Sometimes the required operating conditions for a system are beyond the reach of a single, standard pump. Rather than purchasing a heavy duty pump that may be far more than you need, consider taking advantage of system design strategies to combine simple pump performances that add up to the necessary requirements.

A platform for sliding vane pump and centrifugal pump tests is installed to study the series operation of them under different characteristics of pipeline. Firstly, the sliding vane pump and the centrifugal pump work independently, and the performance is recorded.

Experimental Study on Series Operation of Sliding Vane Pump and Centrifugal Pump

In waterworks and wastewater systems, pumps are commonly installed at the source to raise the water level and at intermediate points to boost the water pressure. The components and design of a pumping station are vital to its effectiveness. Centrifugal pumps are most often used in water and wastewater systems, making it important to learn how they work and how to design them. Centrifugal pumps have several advantages over other types of pumps, including:. A centrifugal pump consists of a rotating shaft that is connected to an impeller, which is usually comprised of curved blades. The impeller rotates within its casing and sucks the fluid through the eye of the casing point 1 in Figure The pressure within the fluid increases accordingly.

Pumps can be arranged and connected in serial or parallel to provide additional head or flow rate capacity. Centrifugal pumps in series are used to overcome larger system head loss than one pump can handle alone. With a constant flowrate the combined head moves from 1 to 2 - BUT in practice the combined head and flow rate moves along the system curve to point 3. Operation of single stage pumps in series are seldom encountered - more often multistage centrifugal pumps are used. Centrifugal pumps in parallel are used to overcome larger volume flows than one pump can handle alone. In practice the combined head and volume flow moves along the system curve as indicated from 1 to 3.

TWO-STAGE (SERIES AND PARALLEL) PUMPS

Call for price. A compact mobile and fully self-contained two-stage centrifugal pump test set that allows students to clearly and effectively investigate the operating characteristics of a centrifugal pump operating in single series or parallel configurations. A compact, mobile and fully self-contained centrifugal pump test set, that allows students to find the characteristics of centrifugal pumps working alone or in series or parallel. It also allows students to see and hear cavitation and understand the use of a Venturi meter and differential pressure measurement to find flow rate. Two bearing-mounted motors drive each pump independently. The pumps draw water from the integral reservoir. The water travels through strainers and a series of valves to be delivered to a Venturi meter.


Although centrifugal pumps are robust, they can fail. If they do fail, it's usually easy to restore them to full operation. Nevertheless, there may be situations requiring.

Experiment #10: Pumps

Worse, he had under-estimated the ruthlessness of Ahmed al Sayyid and just how determined he was to get his hands on the dagger. Now, when in his head he had offered all he had in return for the woman he loved, Allah had tested him, was calling on him to make good his word. With a gesture he made the point that if there was one false move on his part he would pitch her into chasm.

The results show that connecting the pumps in parallel gave a better resistance to cavitation than series connection and single pump operation.
