parallel and series!
A single pump may be insufficient to produce the performance required. Combining two pumps increases the performance of the pumping system.
2.1 Pumps in Series: Two pumps may be connected in series, so that water passes first through one pump and then through the second. When two similar pumps operate in series, the flow rate is the same as for a single similar pump but the total head is increased. The combined pump head-capacity curve is found by adding the heads of the single pump curves at the same flow rate.
Pumps are machines that are used to transfer liquid from a location of low elevation to a higher elevation. There are various types of pumps and they are classified in two major categories:(1) dynamic or kinetic
(2) positive displacement.

Dynamic or kinetic are types of pumps in which energy is continuously added to the fluid to increase its velocity. Centrifugal, jet and turbine pumps falls under this category.
Positive displacement pumps, however, are types, in which energy is continuously added by application of force to an enclosed volume of fluid and resulting to a direct increase in its pressure.Reciprocating, rotary and diaphragm pumps falls under this category.
2.2 Pumps in Parallel: Two similar pumps may be connected in parallel, so that half the flow passes through one of the pumps and the other half through the second pump. When two pumps operate in parallel the total head increase remains unchanged but the flow rate is increased. The head-capacity curve is found by adding the flow rates of the single pump curves at the same head. For similar pumps twice the flow rate of a single pump.
why parallel and series?
Using circulating pumps in parallel or series configurations can attain many economic and operational gains as opposed to using one large pump to supply a system’s pumping requirements.
a combination of in-line pumps rather than base-mounted pumps to accomplish a pumping requirement eliminates the need for pump mounting pads, grouting, and shaft alignment.
Often a designer will specify two pumps, each one capable of handling the entire load. In some cases, this may be essential, but on many installations,
the cost of providing full standby capacity is prohibitive. In most cases, parallel or series pumping can provide 70 to 90 percent of system capacity with no increased cost!

The check valves prevent any flow short-circuiting, especially if only one pump runs.

Ordering Specification!
• A small-scale series/parallel pump demonstration unit, comprising of a water reservoir, two pumps, control valves and interconnecting pipework, all mounted on a stainless steel base.
• Equipped with electronic measurement sensors for pump head pressure (2 off), suction, flow- rate and water temperature.
• Transparent pump volutes for visibility.
• Inlet valve throttling demonstrates air release.
• Supplied with different easily interchangeable impellers.
• Capable of being linked to a PC (not supplied) via a dedicated interface console.
• Supplied with software providing full instructions for setting up, operating, calibrating and performing the teaching exercises. Facilities for logging, processing and displaying data graphically.
• Full theoretical back-up together with a student questions and answers session.
Two motor driven centrifugal pumps, mounted on a stainless steel plinth with a water reservoir and pipework for continuous circulation. The pumps can be configured for single pump operation, two pumps in parallel or two pumps in series by using manually operated ball valves. Similarly, manual valves are used to control the flow and facilitate the study of suction effects, including demonstration of air release.

In parallel operation the two pumps draw from a shared inlet pipe of a wider diameter than the pump inlet, reflecting a typical industrial configuration of parallel pumping. Each pump has impellers that can be easily accessed and replaced without tools. The FM51 is delivered with three impellers in total, one with forward curved blades and two with backward curved blades, allowing the students to investigate the effects of impeller characteristics.
