Safety instructions
1, During start-up and operation, the pump shell must be filled with hydraulic oil (injected into the shell cavity). It must be started at low speed without load until the system is completely emptied; System design, installation and commissioning need to be performed by trained technicians and distributors;
2, When parked for a long time, the oil can be discharged from the shell through the working pipeline. When restarting, enough oil should be injected into the shell;
3,The minimum oil suction pressure of the nozzle S shall not be reduced to less than 0.8 bar. Installation location
4,The axis is horizontal to the bottom. When mounting on the tank, the installation position of "axis level, suction port facing bottom" is not allowed; Installation below tank level; Pump position below minimum oil level in tank (standard)
5,Fill the axial plunger pump before starting through the highest position of the shell outlet. Suggestion: Filling suction pipeline Low-speed running pump (ignition speed) until the pump system is fully filled; The lowest immersion depth of suction or drain pipelines in the tank is 200 mm (relative to the lowest oil level in the tank);
6,Installation position higher than tank level Pumps mounted above the lowest oil level in the tank Installation position below tank level
7,It is not allowed to use the installation position of "shaft against the top" and "axis level, oil suction port at the bottom" (when shutdown, the pump shell discharges oil through oil suction pipeline).
Tightening Torque
1,All the tightening torques listed in this sample are maximum values and should not exceed these values (maximum of internal threads in castings). Please follow the information provided by the manufacturer regarding the maximum allowable fastening torque of the fittings used. · For DIN 13-compliant fastening screws, it is recommended that the allowable tightening torque be checked according to VDI 2230 (promulgated in 2003) in all cases.;
2,The housing, especially the coil, may be particularly hot during or shortly after the operation of the pump. Please take appropriate safety measures (for example, wear protective clothing). - All data and information provided with the product must be complied with;
3,All data and information provided with the product must be complied with..
Note
1,Maximum permissible pipette length Hmax = 800 mm;
2,Minimum Permissible Pressure of Oil Nozzle S (Minimum Oil Absorption Pressure).
