SPH1299™ V2 is based on the reliable, proven concept of linear drive technology for two pairs of serially coupled pump heads. Each of the four pump heads is individually driven and controlled. This generates maximum freedom for flow control and pulse reduction, resulting in a stable and accurate flow, independent of solvent compressibility, pressure and flow rate. In addition to the standard Sapphire seat, one can also opt for a Zirconia seat, to reduce polymer residue build-up.
Purging, disconnecting and even piston replacement are no longer a threshold for you. Using an electrically actuated purge valve, SPH1299™ V2 can truly prime and purge all by itself. No need to help your pump with a syringe for awkward manual solvent aspiration. Up-time of the pump is increased by the active piston backwash. But eventually a seal will need replacement. The pump head has been designed to facilitate easy disassembly and seal exchange in just minutes. Simply disconnect, remove and replace. Besides, the force distribution of the seal is such that it is not possible to break the check valve. The complete pump head is made of high quality 316 stainless steel, with a high-tech coating.
