Preparative Pump: PCP Pump

Pumps series PCP constitute the backbone of Labio production programme. PCP pumps use modular pumping heads and are manufactured as double- or quadruple-head pumps, using unified heads with three different piston diameters. At maximum output the pistons of these high-frequency pumps reach a frequency of up to 300 strokes per minute. All this imposes high requirements both on the quality of the transmission unit, which transforms the rotary motion of the motor into linear displacement of the piston, and on the material of the pistons themselves. The highest stress is always imposed on the seal. On the other hand, the high-frequency solution brings about a number of advantages, primarily low weight and low level of mobile phase pulsation.
