Applications/Product Usage The 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,...

Safety Precautions Before using the product, you MUST read this catalog and MUST fully understand how to use the product. To use the product safely, you MUST carefully read all Warnings and Cautions in this catalog. 1. Cautions related to operation - Use the personal protective equipment to prevent injury when the product is in operation. - Some components are heavy. Handle the product carefully not to hurt your hands and lower back. - Do not step on, hit or drop , or apply strong force to the product, as these actions may cause operation failure, product damage, or oil leakage. - Wipe off...

Handling Precautions 1. Operating Fluid and Temperature Range 2. Filtration and Contamination Control 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. The most important means to prevent premature damage to the pump and associated equipment and to extend its working life, is to ensure that hydraulic fluid contamination control of the system is working effectively. 2) Viscosity and temperature range This begins by ensuring that at the time of...

3. Drive Shaft Coupling 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 dial gauge (reading a) δ =a/2 0.025mm dial gauge (reading b) α=SIN-1 (b/D) 0.2° 4. Oil Filling and Air Bleeding 1) Pump case filling 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...

5. Drain Piping 1) 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 used and the drain...

7. Mounting the Pump Vertically (shaft up) Note: Both the Tair and one case drain port must be used. For applications requiring vertical installation (shaft up) please remove the Tair bleed plug and connect piping as shown in the illustration below. When installing the pump in the tank and submerged in the oil, open the drain port and Tair bleed port to provide adequate lubrication to the internal components. See illustration [A]. The oil level in the tank should be higher than the pump-mounting flange as shown in illustration [A] below. If the oil level in the tank is lower than the pump...
