Ideal for a wide range of chemical feed and core flooding applications 
 
The 500D is ideal for a wide range of chemical feed applications requiring flow rates up to 204 mL/min at pressures up to 259 bar (3,750 psi). With its 500 mL cylinder capacity, this pump can deliver a precise 1 mL/minute for over 8 hours on a single fill. For non-stop continuous flow, see dual pump systems with a choice of valve packages.  
 
As with all D-Series pumps, you'll get accurate, predictable flow and pressure control throughout a remarkable operating range. Patented digital position monitoring servo circuitry provides low-flow precision at any pressure, plus the high speed smoothness and power of a DC motor.
