The GDS High Pressure Syringe Pumps are positive displacement pumps that have been developed from the proven pressure controller range that GDS Instruments have been making for over 40 years. The HPDPC-H version has been enhanced with features that are ideal for core testing and reservoir analysis. These include flow rate control, enhanced resolution and the use of high corrosion resistance Hastelloy. With the ability to operate in pressure, volume or flow control modes, either directly from the keypad or remotely via software, the HPDPC-H is a versatile and simple to use pump.
