Description

The 333/334 HPLC Pumps are reciprocating
piston pumps that provide a preparative
pumping solution accommodating flow rates
from 1 mL/min to 200 mL/min and pressures up
to 3040 psi (210 bar). With additional pumps
in parallel, you can double the flow rate up to
400 mL/min. Individually, a 333 Pump is for
single solvent delivery (isocratic) under high
pressure. When coupled with a 334 Pump,
multi-solvent delivery (binary) is possible.
The 333/334 Pumps are controlled by either
333 Pump software using its control panel
or by TRILUTION® LC Software as part of an
HPLC system.
Hydraulic Components
Open the removable door to view and/or access the hydraulics. Both the 333 Pump and
334 Pump include inlet and outlet tees to direct solvents and reciprocating piston pump
heads to reduce flow pulsation. The 333 Pump has an integrated pressure, purge and mixing
module (PPmm) that functions as a static mixer, a pressure transducer, and a purge valve. The
333 Pump also has an outlet filter to protect columns from contaminants. There is a drip tray at
the bottom of the pump (see Drip Tray on page 30). Solvent bottles can be placed in the tray
at the top of the pump (see Solvent Bottle Tray on page 30).
