Ingersoll Rand / ARO Expert Series 1½" vs. Wilden 2" (P8)
• Air pressure set at 6bar and flow rate at 6.6 metres cubed per hour
Number of cycles per minute for flow rate:
ARO = 45.98 | vs.| Wilden P8 = 30.12
Here we see the ARO 1½" pump cycling 25% more - but the smaller diaphragm has a longer flex life, meaning truly comparable diaphragm life on comparable flow rate requirements. 2" diaphragms have a typical flex life of 15 million cycles versus 20 million for 1½" diaphragms. Also, consider that 1½" diaphragms & pumps are almost half the cost of a 2" diaphragm or pump.
• Air consumption at 6bar
ARO = 27.39 CFM | vs.| Wilden P8 = 45.84 CFM
Wilden pumps use 35% more air on comparable flow rates. On a 24/7 duty this would equate to a saving of £725 on air consumption alone - & THIS IS PER PUMP!! (based on industry electricity currently costing 7p per KW/Hr)
