I. Applications / Product UsageThe following must be taken into consideration before use. 1. The operating condition of the products shown in this catalog varies depending upon each application. Therefore, the product suitability must be judged by the designer of the hydraulic system and/ or the person who finalizes the technical specifications of the machine after analysis and testing. The product specification shall be determined based on the latest catalog and technical documents. The system must be designed taking into account the possibility of machine failure to ensure that all safety,...

1. Operating Fluid and Temperature Range1) Operating fluid Values shown in this catalog are based upon using mineral oil based anti-wear hydraulic fluid. To ensure optimal performance use of mineral oil based anti-wear hydraulic fluid is recommended. 2) Viscosity and temperature range To minimize both oil and seal deterioration, a maximum operating temperature of 60°C should be considered. Please note that the regulator may become slow to respond when operating at low temperatures (below 20°C) in extreme cold environments. At such low temperature it is strongly suggested that a warm up cycle...

Alignment between the prime mover and the pump shaft should be within 0.05 mm TIR*. In case the pump is directly coupled to the engine flywheel, use a flexible coupling. *TIR = Total Indicator Reading Be sure to fill the pump casing with oil through the drain port, filling only the suction line with oil is totally in-sufficient. The pump contains bearings and high-speed sliding parts including pistons with shoes and a spherical bush that need to be continuously lubricated. Part seizure or total premature failure will occur very quickly if this procedure is not rigidly followed. Run the pump unloaded...

m. Handling Precautions5. Drain Piping1) Installation of drain line It is the preferred option to mount the pump with the case drain piping initially rising above the pump before continuing to the tank. Do not connect the drain line to the inlet line. Cautions A) Inlet and drain pipes must be immersed by 200 mm minimum from the lowest level under operating conditions. B) Height from the oil level to the centre of the shaft must be within 1 meter maximum. C) The oil in the pump case must be refilled when the pump has not been operated for one month or longer. The uppermost drain port should be...

Suction line Although K3VLS pumps are equipped with bearings that can accept some external thrust and radial forces, application of such loads will affect bearing life. Depending on the load magnitude , the load position, and the load orientation, bearing life may be significantly reduced.

Technical Information 2-1 Specifications Size * 1: Self prime speed is the maximum operating speed under the self priming condition at maximum displacement. Steady state inlet pressure should be greater or equal to 0 MPa gauge. *2 : Maximum speed is the maximum operating speed that can run without damage to the pump under restriction of operating conditions. ■ Allowable maximum input torque 1. SAE spline shaft (Note) Maximum pressure must be reduced to operate within the allowable maximum input torque as below when the torque limit control is not used. For above options, if 28 MPa is needed,...
