Economical metering pump solutions!
The Concept b mounts easily onto a tank or wall bracket. Adjustment of the pump capacity is via the stroke length in the range of 10-100 % or can be set at 1 of the 4 stroke frequency settings. This gives an adjustment ratio of 40:1.
Your benefits

Note: Above capacities and suction lift refer to pumps tested on water at 115 VAC, 60 Hz, and an ambient temperature of 70 °F (20 °C). Higher specific gravity fluids will reduce suction lift. Capacities will be slightly reduced from published ratings if pumps are skid mounted)
External pulse contact retrofit available as an option (P/N 1046731)
NSF 50 certification only applies to NPB0 & NPB2 liquid ends
