The 500SP 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 179 mL cylinder capacity, this pump can deliver a precise 1 mL/minute for nearly 3 hours on a single fill. For non-stop continuous flow, see dual pump systems with a choice of valve packages.
With a pump height of only 61 cm (23.9 inches), the 500SP can be used in applications where equipment size is limited. 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.
The 500SP pump module has a single-ratio drive train with auto-lubricating gears for long life and low maintenance. Special fittings are used to prevent leaks and ensure safety at maximum pressure.
Wetted materials are compatible with most aqueous and organic liquids, corrosive solutions, heated fluids, liquefied gases, viscous fluids, or slurries and pastes.
