Pulsafeeder Pulsa 7440

Pulsafeeder Pulsa 7440 is selected for applications where chemicals must be dosed accurately into a process, pipeline or treatment system under demanding pressure conditions. It is relevant for industrial dosing, chemical feed, process injection and utility applications where underdosing, overdosing or unplanned downtime can affect safety, quality or operating cost. The model gives engineers a defined duty point for high-pressure metering projects. The pump is based on hydraulically actuated diaphragm metering technology with controlled stroke adjustment. This construction separates the process liquid from the drive side while supporting controlled output adjustment and repeatable delivery. For maintenance teams, the diaphragm metering principle helps reduce leakage risk compared with mechanically sealed transfer equipment and supports predictable service planning. Pulsafeeder Pulsa 7440 has a maximum capacity of 1.667 m³/h and a maximum pressure of 221 bar. The Pulsa family is used for chemical metering duties where flow control, pressure capability and material compatibility must be checked before selection. These values should be reviewed together with chemical concentration, suction conditions, dosing frequency and the required control method. From a total-cost perspective, the right model helps protect dosing accuracy and process continuity while reducing the risk of emergency interventions. AxFlow can support selection, replacement planning, spare parts identification and service discussions for the installed duty. This helps the customer maintain stable dosing performance and manage lifecycle cost over time.
