584X-2X0W (without motor). 584X-2X0W-XXXX (with motor). Model Code Denotes: 1st & 2nd designators = 58 - Series Demand Delivery Pumps. 3rd designator is port size for pumphead housing, where ‘4’ = ¼”. 4th designator is cam angle for flow performance variation only. X can be 0 to 9. 5th designator ‘2’ indicates that pump has bypass relief control. 6th designator is for pressure setting of relief valve. X can be A to Z depending on pressure setting. 7th designator ‘0’ is a code for the specific materials in this model, e.g. Nylon pumphead housing. 8th designator ‘W’ = WRAS Compliant 9th - 12th designators XXXX can be any alphanumeric characters to denote electrical motor and motor mounting base plate combination.
