Solution 

• ICR proposed SPX Flow Internal Gear Pumps in a duty/standby arrangement c/w variable speed electric motors 
• Motor speed was locally controlled by a skid-mounted Ex d control panel 
• Coriolis Flowmeter power supplied via the control panel 
• On-skid equipment earthing provided along with On-skid cable support system 
• Package was installed on a painted carbon-steel base frame c/w integral sloping drop tray with drain valve, certified lifting points, sling set and spreader lift beam 
• Tubing, fittings, valves and components supplied in 316 stainless steel 
• Discharge manifold fitted with dissimilar check valves for increased reliability 

Results & Benefits 

• Pumps capable of pumping viscous fluids at the required flowrate 
• Bespoke control system configured to accept incoming power from client distribution board Overpressure safety built into design with discharge pressure relief valves 
• Stable discharge flow and pressure through use of pulsation dampeners 
• Real time flow rates and cumulative flow displayed locally on Coriolis flowmeter
