The suction pipe size should be at least equal to or larger than the elbows, bends and fittings should be avoided. Pipe sizes should diameter size of the suction inlet on your Wilden pump. The suction be selected to keep friction losses within practical limits. All piping hose must be a non-collapsible, reinforced type because these should be supported independently of the pump. - Page 12 Frequency of use, line pressure, viscosity and abrasiveness of process fluid all affect the parts life of a Wilden Operation pump. Periodic inspections have been found to offer the best means The Pro-Flo pumps are pre-lubricated and do not require in- line for preventing unscheduled pump downtime.
