JP10 SERIES
Performance Curves Dimensions & Standard Specification 4 5
JOYANG JP SERIES provides the ultimate in flexibility and powerful family of hydraulic gear pumps with
numerous displacements, features, and shaft/port option. The JP-series offers the design of a compact, lightweights and efficient line of pumps with pressure-balanced design for high volumetric, mechanical and overall efficiencies. They feature three-piece construction with high strength extrusion aluminum alloy body.
JP20 SERIES
Performance Curves Dimensions & Standard Specification 6 7
JP10 SERIES pumps are available in twelve basic displacements from 1.2 to 10.0cc/rev, operating at
continuous pressures to 210bar and speed to 3000rpm.
JP30 SERIES
Performance Curves Dimensions & Standard Specification Combination Gear Pumps 8 9 10
JP20 SERIES pumps are available in fourteen basic displacements from 4.8 to 31cc/rev, operating at
continuous pressures to 230bar and speed to 3000rpm.
JP30 SERIES pumps are available in ten basic displacements from 21.0 to 63.0cc/rev, operating at continuous
pressures to 250bar and speed to 3000rpm. Complete information can be found by referring to specific sections of this catalog.

[ NOTICE OF USAGE ]
1. Rotational Direction
The pump may rotate either clockwise C.W(R) or counter clockwise C.C.W(L), as viewed from the drive shaft.
2. Filtration
Recommended filtration is 150 to 200-mesh suction filter. Further, the degree of contamination of in-tank hydraulic oil should be maintained to be NAS Class 11.
SAFETY PRECAUTION
Before using any product listed in this catalog, carefully read its operating instructions
Al l information, illustrations and specifications in this manual are based on latest information available at the time of publication. The right is reserved to make changes at any time without notice.

4. System Plumbing
The major objective in the specification of tubing and hose sizes is to limit maximum oil velocity. To avoid pump cavitation, maximum inlet line flow should not exceed 2.4m/sec and inlet vacuum should not exceed 150mmHg(0.2kg/cm2) at the normal operating temperature. On cold starts, a vacuum of 460mmHg(0.6kg/cm2) can be tolerated for short durations. Pump discharge lines should have flow velocities under 6.1m/sec.
Seal Square
5. Hydraulic Oil
The viscosity of hydraulic oil used should be ISO VG32 to VG68 or equivalent. Recommended viscosity is between 20 and 60 cSt(mm2/s). The viscosity range of 10 to 400 cSt(mm2/s) is applicable under load.

7. Oil Reservoir
The reservoirs are ideally sized so the volume of reservoir oil is not replaced more than twice per minute.
