Flood Coolant Dispensers with Reservoir

These dispensers have a reservoir for recirculating coolant. They provide a constant flow of coolant, so they dissipate heat more efficiently than mist and droplet dispensers, making them suitable for cooling long machine cycles. Coolant strainers prevent debris from getting into the recirculated coolant.

Maximum flow rate and shut-off height are for water-soluble oil. Shut-off height is the maximum height to which the water-soluble oil can be pumped.
