Double-suction pumps are employed when the flow rate required of a centrifugal pump becomes too large for the inlet cross-sections of one impeller or when the flow velocity in the inlet cross-section of the first impeller has to be reduced to prevent cavitation. In principle, fourfold or sixfold suction designs are possible.

THE WORKING PRINCIPLE OF A DOUBLE DIAPHRAGM PUMP A double diaphragm is a positive displacement pump which utilises two flexible diaphragms that reciprocate back and forth, creating a temporary chamber, which both draws in and expels fluid through the pump. The diaphragms work as a separation wall between the air and the liquid. The first stroke

We just saw in this pump liquid enters through the suction and flows into the impeller of the first stage. This impeller has a suction eye on both sides. And is often called a double suction impeller from the discharge of the first stage volute. The liquid flows into the second stage suction.

A spinoff from the end suction pump is the double suction pump. An end suction pump draws up liquid through a single input, and an imbalance of thrust can be created when it exits the motor's centrifugal force. Double suction pumps bring liquid into two chambers and equally distribute liquid, easing the wear and tear on the mechanism.

Jun 26, 2017 This double suction design splits the flow inside of the pump and sends 50% of the water through two “eyes.” This splitting or double suction design eliminates the axial forces on the impeller which allows for higher flows than single suction pumps.

Jul 04, 2021 Double Suction . Single-suction will not suffice when the flow rate is too high. In this case, double suction centrifugal pumps are used. The impeller of this pump is engineered so that fluid enters from both sides in comparison with the single side in a normal case. However, the name “double suction” must not confuse you.

The RANS (Reynolds-averaged Navier–Stokes equations) with CFD (Computational Fluid Dynamics) simulation method is used to analyze the head hump formation mechanism in the double-suction centrifugal pump under a part load condition. The purpose is to establish a clear connection between the head hump and the microcosmic flow field structure, and reveal the influence mechanism between them.

MoreCentrifugal pumps are used frequently in multiple pump installations where the pumps are piped to the same suction and discharge lines. The combined flow rate is the summation of the individual pump flows at the same TDH. In parallel operation the capacities for each pump are added at any given head.
MoreSep 21, 2016 Typically these pumps offer dual volute construction, which significantly reduces the radial thrust component. Disadvantages of HSC pumps: The pump is sensitive to horizontal elbows on the pump’s suction side. Fluid flow through the horizontal elbows induces asymmetrical pressures on the impeller that lead to shortened bearing and seal life.
