Grad series gradient pump is consisted of two independent high-performance pumps which can be operated independently. As such, the default of system failure caused by the malfunction of one pump unit in low pressure gradient system is completely avoided. The middle pressure gradient is formed at the outlet of pump, and the mixing dead volume formed under the low pressure gradient mode is greatly diminished. The gradient is easier to be controlled. The middle pressure gradient mixing mode eliminates the air bubble problem emerging under the mode of low pressure gradient mixing mode, and has very excellent repeatability.
