1. Quadna Field Installation Expert Field Installation Including Start-up and Commissioning Field Service Quadna Field Installation Expert Field Installation Including Start-up and Commissioning Field Service Quadna – Engineering Innovative Solutions for Industrial Applications Pumping Systems UNLEADED FUELONLY A pumping system consists of: All piping characteristics such as diameter, material, length Vessels (tank or sump dimensions) Other types of equipment (valves, meters, elbows, etc.) Valve Pump Valve Pumping Systems

2. Quadna – Engineering Innovative Solutions for Industrial Applications Pumping Systems (Suction Head) Suction head implies that the liquid level is above the inlet of the pump Flooded suction arrangements can use a straight centrifugal pump Pump To Loading Rack 3” Pipe

3. Pumping Systems Quadna – Engineering Innovative Solutions for Industrial Applications Pumping Systems A pump must overcome the resistance of a pumping system in order to cause a liquid to flow completely through the system Resistance to liquid flow is known as a pumping system’s Total Dynamic Head Pump Resistance Head

4. Pumping Systems Quadna – Engineering Innovative Solutions for Industrial Applications Pumping Systems Total Dynamic Head is the sum of two parts: + Dynamic Head =Total Dynamic Head Static Head

5. Pumping Systems Quadna – Engineering Innovative Solutions for Industrial Applications Pumping Systems (Suction Head) In this example the static head is equal to: 25’ – 8 = 17’ Pump To Loading Rack 3” Pipe 20’ 25’ 20’ 2’ Low 10’

6. Pumping Systems Quadna – Engineering Innovative Solutions for Industrial Applications Pumping Systems In this example the static head is equal to: 4’ + 4’ + 2’ + 25’ = 35’ ’ Pump To Loading Rack 3” Pipe 8’ 2’ 4’ 20’ 25’ 20’ low4’ (Suction Lift)
