ABSTRACT:
A high pressure meter pump system with improved accuracy is provided by subdividing a large meter pump capacity into metered subvolume charges which are incrementally delivered to a high pressure slave pump.
This enables the pump sytem to achieve improved accuracy independent of flow rate and therefore increasing the range of flow rates available with acceptable accuracy. Additionally, the pump system self-primes independently of flow rate and therefore does not require degassing of the solvent being pumped.
