V-10 (56C Frame Flange Drive) Series Piston Metering Pumps Duplex Pump Head with a single drive to two pump heads. Stroke lengths and flow rates are calculated per head. All the various piston head sizes are interchangeable which makes application changes in the field simple. The standard simplex pump can readily be converted to a duplex pump in the field. Multiple head pumps can be fitted with identical heads or different sized heads for custom applications. All V-10 pumps are supplied with a pressure relief valve for each pump head.

If opting to use your own motor, ensure motor's compatibility with the pump by using a 56C frame 1750RPM flange drive motor.
