General Description Technical Description The K3VL Series Swash Plate Type Axial Piston Pumps are designed to specifi cally satisfy the marine and general industrial machinery market where a high pressure variable displacement pump is required. K3VL Pumps are available in nominal displacements ranging from 45 to 200 cm3/rev with various pressure, torque limiter, and combination load sensing control options. The components of the K3VL pump can be divided into three sub-groupings: Rotating Group Providing the main rotary pumping action. Swash Plate Group ֖ To vary the pumps delivery fl ow...

Swash Plate Group Technical Description (continued)The Rotating Group The Rotating Group comprises: (a) Valve plate 313(b) Cylinder block, 141 (c) Pistons, 9 x 151 + Shoes, 9 x 152 (d) Setting plate, 153 (e) Spherical bush, 156 (f) Cylinder springs, 9 x 157The drive shaft is coupled to the cylinder block through a splined section and supported at both of its ends by bearings. The shoe is swaged over the spherical end of the piston forming a spherical ball joint. Additionally the shoe has a hydrostatic pocket to balance the hydraulic thrust developed by the piston pressure allowing the shoe...

By suitable use of adaptors and splined couplings a wide variety of through drive mounting capabilities are available. The formation of these kits and their relevant part numbers will be found in the installation section. Technical Description (continued)Valve Cover Group The Valve Cover Group comprises: (a) Valve cover, 312(b) Valve pin, 885The valve plate with its two kidneyӔ shaped ports is installed onto the valve plate located by the valve plate pin. These two ports serve to supply and exhaust oil to and from the cylinder block. The oil passage switched by the valve plate is connected...

Technical Data (continued)Filtration & Contamination Control Filtration The most important means to prevent premature damage to the pump and associated equipment and toextend its working life, is to ensure that hydraulic fl uid contamination control of the system is workingeffectively.This begins by ensuring that at the time of installation that all piping, tanks etc. are rigorously cleaned in a sanitary way. Flushing should be provided using an off line fi ltration system and after fl ushing the fi lter elements should be replaced.A full fl ow return line fi lter of 10 micron nominal...

Technical Data (continued)Pump Start Up Precautions Pump Case Filling Be sure to fi ll the pump casing with oil through the drain port fi lling only the suction line with oil is totally in suffi cient. The pump contains bearings and high-speed sliding parts including pistons with shoes and spherical bushes that need to be continuously lubricated. Part seizure or total premature failure will occur very quickly if this procedure is not rigidly followed.Piping & Circuit Checking Check to see that the piping and full hydraulic circuit is completed and that any gate valves etc. are...

Radial Loading Capacity No axial shaft loading possible Radial loading is achievable but in specifi c orientation:- In addition because of the high bearing capacity of this front bearing, radial shaft loading can be allowed provided that its orientation is such that it is this front bearing that takes the additional load(See diagram below). > acceptable not acceptable Model K3VLPage 20.Data SheetP-1002/02.09 >
