use a fast response variable pump that has a very high efficiency and low noise.The variable pump continuously adjusts the output pressure and volume of the pump to match the values called for on the screen for the various parts of the moulding process. This system contrasts with fixed delivery pumps employing valves to control the required pressure and volume, and dumping excess oil to tank. This can result in energy savings of 20%-40% compared with normal machines.
