HPLC and flow chemistry Pumps

LC Pumps from FLOM, made in Japan

Pumps for HPLC, UHPLC and flow chemistry

Flom (part of GL Sciences), is a manufacturer of HPLC and UHPLC components. Choose from a wide range of pumps, from high performance types with automatic control of flow rates, to simple pumps at an affordable price.

MP-22 Series, No-Pulsation Linear-drive Pump
LC pump without check valves At low flow rates (0.5mL/min. or lower), check valves become an variable factor for flow volume and pulsation. The new MP-22 doesn’t use any check vales but instead it is using a fast switching valve. This results in stable flows and pressure even with low flows.

Driving method Linear-drive pump + auto switching valve
Selectable flow rate Controllable range of pulsation:10~500µL/Min.
Wetted materials Pump: SUS 316, High-density polyethylene, Kalrez, Sapphire, PFA and PEEK
Valve: SUS316 and PEEK
Maximum pressure 20 MPa (2900psi)
Plunger diameter 3.2 mm
Plunger stroke 10 mm
Flow per stroke 80µL
Flow accuracy < 0.3%
