CROSS GEAR PUMPS/ 50 MOTORS

1 CROSS gear PUMPS/ MOTORS50 SERIESThe CROSS Series 50 gear pumps / MOTORS feature a gear tooth design that provides more displacement within a given package size. The gear tooth design and pressure balanced loading plates provide for a high volumetric and overall efficiency while operating at a low noise level. Available in 7 sizes, with displacements from to cubic inches per revolution, this compact unit can deliver up to 45 US. gpm. in a space less than 6-1/2 x 5-3/4 x 7-1/4 .MATERIAL SPECIFICATIONSBody and end cast aluminium lubricated, Teflon impregnated sleeveGENERAL SPECIFICATIONSD isplacement PUMPSR ated working pressure (max. relief valve setting at full flow).
