This paper deals with state-of-the-art-design of a pump-sump and the criteria for its model testing. A 1 ∶ 10 scaled model of a pump-sump with five cooling water pumps and three auxiliary cooling water pumps was tested, and the model results related to separation of flow, dead zones, surface and subsurface vortices, swirl angle, etc., are Cited by: 7.
GUIDELINES FOR PUMP SYSTEM DESIGNERS Jacques Chaurette p. eng. August Synopsis The following is a list of potential problems areas or simply just good design practice that the author has applied and encountered over the years. They deal mainly with piping issues that affect pump performance.
Size: KB. pump-intake and discharge-flume structures, if found during the course of the study, was the ultimate objective of this model investigation. The more specific, principal concerns were as follows: (1) the effect of the narrow, pump-sump cross section at the dual-flow traveling-screen exit on pump-approach-flow velocity distribution in each sump.
utilised to identify the source of particular problems with a pump sump or intake and find practical solutions to rectify them (Jones, ). Such investigations have generally resulted in successful solutions to identified problems, however, physical model studies are time consuming and expensive.
The present study analyzes pump sump flows with various discharges and gate submergence. Investigations using a three-dimensional large eddy simulation model and an acoustic Doppler velocimeter are performed. Flow patterns and velocity profiles in the approaching flow are shown to describe the flow features caused by various discharges and gate submergence.

The lower limit is determined by the dramatic increase of costs for large slurry Sump Pumps, also an established name typically operating pumps from floor sumps, submerged pump houses.
In a positive-displacement (PD) pump, a discrete amount of fluid is trapped, forced through the pump, and discharged. A gear pump is an example of a PD pump (Figure 2). This pumping principle produces a pulsating flow, rather than a smooth flow. Its output flow tends to vary little with respect to the pressure at the pump outlet, because the moving.

submersible pumps. A proper design of the pump sump in such installations is crucial. Two important design objectives are; preventing significant quantities of air from reaching the impeller, and disposal of settled and floating solids. The Flygt standard pump sump can be used as it is, or with appropriate variations to meet the requirements of.

my professor advised me to read this book, who is a good hydraulic engineer. after reading this book i got good understanding about the sump design and problems involved with poor s: 1. pump and motor bearings related problems (loss of lubrication, cooling, contamination of oil, abnormal noise, etc), leakages from pump casing, very high noise and vibration levels, or driver (motor or turbine) related problems.
The list of pump failure conditions mentioned above is neither exhaustive nor are the conditions mutually exclusive. The Sump Pumps Direct experts explain the different types of sump pump systems you can buy and which is the best application for each.
Learn the differences between combination sump pumps and backup sump pump systems and get expert buying advice, sump pump tips, and product information. Six steps to pump sizing.
In order to size a pump, engineers need to estimate the temperature, density, viscosity and vapor pressure of the fluid being pumped.
Pump sizing can be accomplished in six steps, as follows: Find the total dynamic head, which is a function of the four key components of a pumping system, such as the one shown in Figure 1. Sump Design Criteria a) Sump Pit Details.1 Sump pits are to be a minimum of mm (30”) deep, and m2 in area Sump pits are to be fitted with a tightly fitting removable cover Sump pits will be constructed of concrete, plastic, or non-corrosive metal Locate sumps as close to the basement exterior wall as possible.
Proper pump intake design takes care of problems referred above. Though pump sump and intake are designed as per general guidelines actual design and measures for its smooth functioning are finalized through model studies. The composition of the committee responsible for formulation of this standard is given in Annex A.

KSB offers a broad. For many homeowners the first line of defense against water in the basement is a sump with a pump in it. The sump may be connected to drain tile that drains the footings of the house, under the entire basement, or just the area where the sump is located.
Many houses have tiling installed only around a portion of the house. The water that drains into the sump must be removed, and this is. the model gutter was measured up to cm in the model, or cm in the prototype. For each run, wa-ter flow was circulated from a pump through the flume, and then intercepted by the sump inlet.
Before a measurement was taken, the system was first operated to establish a. In selecting a pump, one of the concerns is to optimize pumping efficiency.
It is good practice to examine several performance charts at different speeds to see if one model satisfies the requirements more efficiently than another.
Whenever possible the lowest pump speed should be selected, as this will save wear and tear on the rotating parts.
