Fixed Speed, Duplex Diaphragm Pump

• Economical and versatile.
• Dual pump head design for simultaneous injection of two chemicals, or high volume of one.
• All ball bearing, permanently lubricated gear motor for smooth, quiet, powerful operation.
• Stroke adjustment from 5-100% permits accurate small injections at a high rate per minute.
• Outputs to 48 LPH (304. 2 GPD). (Total both heads)
• Output pressures to 125 PSI.

Output Control Options:

Standard Models feature a quick adjusting, high accuracy mechanical stroke length control. The pump’s efficient design allows for a minimum stroke length of 5%. Minimum recommended output is 5% of maximum. Each pump head is independently controlled.

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.
