Chem-FEED C-1700N diaphragm metering pump features a quick adjusting, high accuracy mechanical stroke length control.  The pump design allows for a minimum stoker length of 5%.  Minimum recommended output is 5% of the full stroke. Each pump head is independently controlled.  All ball bearing, permanently lubricated gear motor are designed for smooth, power and quiet operation. 

Deluxe Models feature stroke length and electronic time Interval control. The pump’s on time is adjustable from 5-100% of the repeating 5 second time interval. (0.25 – 5.0 sec.) The high frequency of the repeating 5 second time interval, and the extremely accurate mechanical stroke adjustment, result in a higher frequency of small injections per minute. Minimum recommended output is .5% of maximum. Each pump head is independently controlled. 115V/60Hz, 230V/60Hz and 220V/50Hz models are available.
