The pump is microprocessor-controlled with serial dual-reciprocating pistons to eliminate the distur bance of flow pulse.

It has a RS-232/485 interface, and can bring about dual to quaternary gradient elution with computer remote control.

With advanced seal technology and pump head self-cleaning function, the pump could work under high pressure for a long period.

Pump operating pressure: 0~42.0MPa(stainless steel), 0~36MPa(PEEK)，0~50MPa for special request

Flow rate range: 0.001ml/min~9.999ml/min

Flow rate precision: RSD<0.1%(measured at no more than 1ml/min)

Pressure sensor: Pressure displaying precision: 0.1 MPa

Gradient ratio precision: ≤±0.1%(2.0ml/min)

Overpressure protection: The pump will stop and alarm automatically when working pressure is out of normal pressure range.
