HPLH PulseFree pump

The pulse-free HPLH pumps are employing two interdependently controlled pump heads which results in a pulse free flow without any need for secondary pulse dampeners. Unlike syringe pumps the flow is continuous without the need for refill cycles or valve switching.


The pulse-free HPLH pumps have the same performance and features as our standard HPLH pumps like the fast and easy setting and adjusting of all values via the intuitive controller or the pre-programming of the units for volume, flow-rate and specific weight, e.g. μl, ml, mg, g, μl l/s, ml/m.


The HPLH PF is available with 2 different pump heads: 20/200.
