Pumps (Selection- Operation- Maintenance)

On completion of such training course; trainees should be able to do & aware of the following:
• Effectively operate, maintain, select & increase the availability of pumps & systems.
• Provide ability of the in-charge personnel to train workers on dealing with pumps & systems safely & efficiently.
• Helps workers & concerned personnel to enhance methods leading to decrease pump failures & downtime.
• Distinguish types of pumps & imagine practically how their working is, suitable requisitions, installation, maintenance methods.

• Introduction/pumps in practice, definition/function/ principles of operation.
• Classification of pumps, introduction to flow in pipes/fluid properties.
• Governing equations of compressible & incompressible flow
1.Continuity equation. 2. Bernoulli’s Equation.
• Losses in pipes/Reynolds number (RN)/Darcy Equation.
• Change in velocity magnitude (due to area change/bends or elbow)/Loss in valves /Valve Types, Piping System/ and its calculations /Piping system curve.

• Power: input & output power, pump performance curves
• Importance of pipe system curve/understanding the pipe system curve
• Variants in pumping systems, variable static head/variable system resistance
• Centrifugal pump performance, characteristic curves: ideal pump and fluid, Euler’s head-capacity characteristics, loss in a centrifugal pump, real pump, and fluid
• Affinity laws; constant & variable speed (N=const., D=const.), specific speed.
• Modifications to impeller & casing, the effect of fluid viscosity.
• Cavitations: causes, signs, how to minimize, how to prevent the pump from cavitation’s, reduction of cavitation damage, net positive suction head (NPSH).
• Pump selection, starting centrifugal pumps/priming, parallel and series operation.
• Centrifugal pump construction (single & multi-stage): classification, casings, radial thrust impellers, impeller mechanical types, wearing rings, axial thrust, axial thrust in multi-stage pumps, shafts, and shaft sleeves, seals (packing & mechanical), lantern ring.
• Centrifugal pump installation: (foundations, alignment, grouting)
• Centrifugal pump operation: pump preparation for start-up, starting procedure, stopping procedure
• Positive displacement pumps: introduction, some notes on flow and pressure, types of pumps & differences between both types, the principle of operation, performance curves, description of (reciprocating-piston, diaphragm, screw, gear, vane, radial & axial pumps- swash plate…etc.), efficiency: (Mechanical volumetric, and overall efficiency), performance
• Effects of air and other gases on pump life and performance.
