About Centrifugal Pumps Series And Parallel Connecte

CENTRIFUGAL PUMPS, SERIES AND PARALLEL CONNECTED

In complex systems, pumps can be connected in series or in parallel. In series operation, the heads are added, and in parallel operation the flow rates of the pumps are added. The series and parallel configuration of pumps is very well suited to understand the similarities with an electric circuit.

Equipped with two standard centrifugal pumps that are delivered ready for installation, mounted on a plate. The centrifugal pumps are installed in the supply unit with just a few simple steps, connected via hoses with quick-release couplings, and attached with clamping levers. To power the pumps, they are connected to the drive unit with a V-belt.

The pressures at the inlet and outlet of the centrifugal pumps are recorded with sensors. The measured values are read from digital displays on the supply unit and can be transmitted simultaneously via USB directly to a PC, where they can be analysed using the included software.

Efficient Laboratory Demonstrator

Purpose-built for laboratory environments, this centrifugal pump unit enables hands-on experimentation with series and parallel configurations. Its compact, bench-top design and clear water handling make it ideal for education and research, supported by easy-to-read analog displays and sturdy, corrosion-resistant build materials.

Accurate Flow and Head Measurement

Users benefit from highly reliable flow readings (0.13 LPM) through both direct orifice and rotameter measurement systems. With a maximum head of 18 meters, the demonstrator provides precise control and insight into pump performance under varying configurations.

Durable and User-Friendly Design

Constructed with powder-coated mild steel, SS304, and cast iron, the unit resists wear and corrosion. Individual pump switching and analog display enhance usability, while a manual operation mode encourages deeper learning and experimentation.

FAQs of Centrifugal Pumps Series And Parallel Connecte:

Q: How are the centrifugal pumps connected in this demonstrator?

A: The two identical centrifugal pumps can be operated in either series or parallel configurations, allowing users to compare and analyze pump characteristics under different connection types within a single laboratory setup.

Q: What kind of flow measurement options are available?

A: This equipment provides both direct orifice and rotameter-based flow measurement, supporting a measurement range from 0.1 to 3 LPM for accurate and versatile data collection during experiments.

Q: When should I use series versus parallel connection?

A: Series connection is ideal when a higher head (pressure) is needed, while parallel connection is used to achieve higher flow rates. Both configurations can be demonstrated to illustrate their effects on pump operation.

Q: Where is this centrifugal pump demonstrator typically used?

A: The unit is primarily utilized in educational and research laboratories for practical demonstration and study of centrifugal pump dynamics, suited for universities, technical institutions, and training centers.

Q: What is the process for operating the pumps?

A: Each pump can be independently switched on or off using manual controls, enabling experiments in both series and parallel arrangements. Flow is measured via analog display using either the orifice or rotameter methods.

Q: How does the demonstrator benefit laboratory users?

A: It provides an interactive and efficient way to study pump performance and fluid flow principles, enhancing understanding through accurate, repeatable, and hands-on experimentation.

Q: What materials ensure the durability of this equipment?

A: The demonstrators main frame is made from powder-coated mild steel, with wetted parts in SS304 and pumps constructed from cast iron, ensuring corrosion resistance and long-term reliability.
