Patent Pending 1530-0024S2 NPT Self-Priming Adaptor1530-0025S1-1/2Ԕ BSP Self-Priming Adaptor Hypros Self-PrimingAdaptor provides fastself-priming of closedimpeller centrifugalpumps, reducing fill timewhile protecting themechanical sealfrom dry-run. Creates self-primingcapability for allstandard centrifugalpump models. Creates self-priming capability for all standard centrifugal pump models > Increases priming efficiency over open impeller transfer pumps and self-priming centrifugal pumps > Allows the use of a single high efficiency pump for both tank filling and spraying > Constructed out of 304 stainless steel for corrosion resistance > Protects the pumpsmechanical seal from dry-run during priming operations for on-board loading > Guards against unexpected dry-run conditions during spraying application, if system were to function automatically > Allows centrifugal pumps to be mounted in tight-fitting configurations while maintaining priming and flow performance capabilitiesՕSPAcan be mounted in nearby remote location up to 10 feet (3 meters) from pump >
