Concrete Pump – Linde Hydraulics

Since the control signal for the pump is always the same, there is no need to change the software in order to adapt the machine to different conveyor heights or different concrete textures. The other components of the open hydraulic circuit are fed by a HPR 55-02 self-regulating pump which is also very silent due to its pulsation damping SPU unit.

Closed Loop VS Open Loop Hydraulic Systems - CrossCo

Mar 21, 2017 · If someone talks about an "open loop" or "closed loop" hydraulic system, what exactly do they mean?Fundamentally, the difference can be described in just two sentences, and is most easily defined by the pump: An open loop pump draws all of its flow directly from a reservoir and sends the majority of it directly back to the reservoir after performing its function.

Hydraulics innovations in concrete pump trucks

Jan 07, 2020 · It is the cylinder stroke speed that produces the production-critical concrete pumping rate. Two large, closed-loop, hydrostatic pumps are connected in parallel for redundancy in order to reliably drive the two, 8-ft-long, single-rod cylinders that stroke the concrete pump plungers. The choice of a quick-response, swash-plate controlled, closed-loop piston pump removes pressure drop issues that can accompany a proportional, directional valve in a conventional open-loop …
