PULSA SERIES and PULSAR hydraulically actuated diaphragm metering pumps are ideal for colourant metering applications. The pumps can be designed with hardened valve seats and balls to provide premium service life for abrasive chemical duty. Additionally, the pumps can be multiplexed in applications where ratioed addition of several colors is required. For transferring paint thinners, alcohols, and other thin, non-lubricating fluids, our ECO GEARCHEMS are a great solution. The pumps can also be equipped with flush port t o help ensure that the pump is clean after taken out of service.
