Centrifugal Pumps & Positive Displacement Pumps

5 days MTE/PC-E
Level
Proficiency
Audience
  • Engineers and technical staff involved in centrifugal and positive displacement pump operation, maintenance or engineering.
Purpose
  • This course covers the centrifugal and positive displacement pumps technology & their operating conditions.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • describe the behavior and the operation of pumps,
  • participate actively in troubleshooting analyses and help to diagnose failures,
  • identify main parameters in pump selection.
Prerequisite
  • There are no prerequisites for this training.
Ways and means
  • Actual examples from the refining, petrochemical and chemical industry.
  • Active participation is encouraged through case studies.

HYDRODYNAMICS APPLIED TO A PUMPING SYSTEM 2 days
  • Pump performance:
  • Flow in a pump, velocities triangle, internal flow and energy losses.
  • Theoretical and practical head: characteristic curve.
  • Other characteristics: efficiency, power, NPSH required.
  • Changes in characteristics vs. rotation, viscosity, impeller shape, cavitation.
  • Pipe system:
  • Liquid flows in pipes: friction losses.
  • System curve, resistance of flow and throttling control.
  • Operating point: normal and maximum capacities, change in fluid characteristics and incidence on operating conditions.
  • Technical application: study of a distillation column reflux line and the pump installed.
CENTRIFUGAL PUMP TECHNOLOGY & SELECTION 2 days
  • Centrifugal pump:
  • Construction and technology: API and ISO specifications.
  • Internal forces and mechanical criteria: balancing, wear ring clearances.
  • Impeller and pump shape, suction operating conditions.
  • Mechanical seal:
  • Selection according to API 682 standard & type.
  • Friction face heating.
  • Safety and environment: typical arrangements (single, dual, dry seal).
  • Specific solutions: canned motor pump, magnetic drive pump.
  • Installation:
  • Suction and discharge pipe design.
  • NPSH available; base plate and grouting.
  • Ancillary lines and equipment.
  • Coupling and driven machines.
  • Safety and environment.
POSITIVE DISPLACEMENT PUMP TECHNOLOGY & PERFORMANCE 0.5 day
  • Technology: different types of pumps (rotary and reciprocating pumps). Operation & performance of the different types of pumps.
  • Influence of clearance, internal leaks, nature of product on flow rate and pressure. Flow rate control.
  • Installation guidelines: position of tanks, line diameters, metering drums, pulsation dampeners, pressure valves.
PUMP OPERATION 0.5 day
  • Preparation: filling & draining. Start-up/Shutdown: priming, hammer shock, risks to the process and the pump.
  • Monitoring parameters (vibration levels, noises, bearing housing temperature, motor intensity, pressures).
  • Parallel and serial operation. Safety conditions.
  • Reliability: types and source of failures (wear, ruptures, cavitation, leakages); improvement methods.
