JN Series Diaphragm Metering Pump

These simple, 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.

Features

• 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.
