These proven, rugged, accurate pumps are used in many industrial plants for injecting a controlled flow of highly reactive liquids. Heavy duty industrial grade construction means those little pumps will deliver many years of trouble free 24-7-365 pumping.
• JN Series Pumps are designed for especially low rates. Double ball checks with Teflon valve seats assure ±1% steady slate repeatable accuracy over a 10:1 turndown range.
• Manual output control knob is located on top of the pump for easy access.
• Automatic pump output control is available for pumps equipped with a variable speed motor.
• Industrial grade worm gear reducer is permanently lubricated and C face mounted to the motor. Precision internal pump parts run in an oil bath for extended service life. No external lubrication required.}
• Double diaphragm option is available for superior protection from dangerous liquids.
• When equipped with the proper materials the JN Series pumps are excellent for pumping dangerous liquids such as acids, caustics and solvents.
• Tough fabric reinforced rubber diaphragms protect the drive train from the pumped liquid. The short .090″ stroke with 2″ diameter piston increased diaphragm life by reducing fatigue.
