LPV Series pumps are variable volume, positive displacement pumps that feature unparalleled reliability and consistent performance. Their small size, light weight and maintenance free design permit the pumps to be located where the fluidic requirements dictate, regardless of maintenance accessibility. This makes them ideal for replacing conventional syringe and peristaltic pumps. This also allows the pumps to be located on or near the sample arm, further reducing the required transport volume of the system.
Standard LPV Pumps incorporate a stacked can motor, which creates a smaller, lighter package. A home sensor is available as an option.
High Performance LPV Pumps use a hybrid stepper motor, which allows smaller dispense increments and higher pressures. Encoders and home sensors are included with these pumps, allowing positive feedback.
High Performance pumps are also available with dual seals. The second seal creates a "flushing" chamber which allows the use of a barrier fluid. Flushing of the piston to prevent build up is also possible.
