Summary

WHEATSTONE precision metering pump is a high pressure syringe pump that provides truly pulse-free pumping with unmatched precision and accuracy. These positive displacement metering pumps are ideal for handling aqueous solutions, brines, hydrocarbons, refined oils and gases such as CO2. 

A pair of cylinders can work together to pump continuously for any length of time, from seconds to months. You can pump fluid at either a constant flow rate or a constant pressure, specifying the precise flow rate or pressure to be maintained. A ramping feature enables the pumps to provide a smooth transition between multiple rate, pressure, or volumetric settings.WHEATSTONE pumps can also operate in either direction, letting you easily deliver or receive fluid to or from an application. 

The high temperature version of WHEATSTONE pump allows the entire syringe pump body to be placed in an oven, with the motor extending outside the oven wall. By keeping the fluid, piston and cylinder barrel at a uniform temperature, volumetric errors due to thermal expansion and contraction are eliminated. Optional temperature control jackets provide a means of heating or cooling the cylinder barrels when oven placement is unnecessary.
