H220 High Pressure Bolted Metal SUCTION LIFT CAPABILITY H220 METAL SUCTION LIFT CAPABILITY Suction-lift curves are calibrated for pumps operating at 305 m (1,000') above sea level. This chart is meant to be a guide only. There are many variables that can affect your pump's operating characteristics.
The suction pipe size should be at least equal to or larger than the to a solid location, a mounting pad placed between the pump and the diameter size of the suction inlet on your Wilden pump. The suction hose foundation will assist in minimizing pump vibration. Flexible connections must be a non-collapsible, reinforced type because these pumps are capable of pulling a high vacuum.
Frequency of use, line pressure, viscosity power returns. and abrasiveness of process fluid all affect the parts life of a Wilden pump. Periodic inspections have been found to offer the best means Air-Operated Pumps: To stop the pump from operating in an for preventing unscheduled pump downtime.
