ECP2200H Preparative Pump

This pump works as an isocratic pump and together with a gradient box also as a gradient pump.

These powerful and durable pumps are suitable for preparative applications in low- and high-pressure liquid chromatography across the chemical industry. They are designed with 2 pump heads connected in parallel with a piston diameter of 3/8”.
Many improvements make these pumps more reliable, including a new learning algorithm for pulsation suppression and a leakage sensor. New material versions have been added-in, beyond to stainless steel A316L, also Hastelloy, titanium and PEEK for biocompatible applications.
The pumps can operate in two modes, i.e. using constant pressure or using the newly added option of constant flow rate. 

Gradient function: These pumps work as isocratic pumps, and, together with ECOM gradient boxes, they also work as gradient pumps. Gradient boxes ECB2005, ECB2005PC are equipped with a four-way gradient mixing valve and must be ordered together with the pump. These sophisticated units allow for achieving a precise low-pressure gradient, i.e. gradual changes of solvent composition by mixing up to four liquids at the pump‘s entry. The gradient profile can be defined via a computer or manually using a display and a keypad. Without the use of a gradient box, the pump works as isocratic, with the option of one solvent and the composition of the mobile phase being chosen by the user.

Customers can use the pistons‘ back-washing function, after working, for example, with a buffered mobile phase.

Seals: All pumps are delivered with GFP (PTFE) seals by default. You can order the pumps with UHMW-PE seals, which are considered the optimal recommended choice.

Software support: The pumps are supported by ECOMAC and Clarity software.

This pump is equipped with the Pressure Compensation Learning algorithm. Thanks to this smart adaptive process, the pump regulates the rotation speed of the camshaft and measures its impact on pressure pulsation to minimize the output pulsation as much as possible. The algorithm, due to its adaptive capacity, is applicable for many combinations of pump working conditions (solvents, columns, etc.).
