The consistent ongoing development of the SLH Twin Screw has been based on our many years of experience working with our customers, general market requirements and the demands of relevant directives and certifications. Bornemann SLH twin screw pumps are single-flow and self-priming. Two contact-free inter-meshing screws and the pump housing form closed chambers that, according to the direction of rotation, constantly move towards the pressure discharge end of the pump.
