Installation and Use:
1.In installation, the tolerance of concentricity between shaft of pump and motor must be less than
0.10mm(TIR) and the maximum permissible angle error is less than 0.2 degrees by using the
flexible coupling; The pump shaft shall not bear the radial and axial load; The carrier must be firm
with good rigidity and can fully absorb vibrations.
2. Fix pipes, especially inlet pipes in accordance with the size of port and assemble safety relief valves
in the system( the inlet flow rate is between 0.5 and 1.5 m/s ). The regulating pressure of the safety
valve shall not be greater than the maximum pressure of the pump; Inlet pipes must be strictly
sealed with no leakage; Inlet pipes must be strictly sealed with no leakage; The fuel tank shall be
equipped with a diaphragm to separate the bubbles and dirt from the oil; The oil return nozzle
should be lower the fluid surface, the minimum depth of 50 mm, even in a low, too, when the
permissible level of to avoid the formation of bubbles .
3.Set the suction pressure at pump inlet port : oil hydraulic oil is + 35 ~ -16.7 KPa. The hydraulic oil
of water - glycol and phosphate ester was + 35 ~ -10.1 KPa.
4.In case where the pump is installed on the tank or at the position higher than the tank top cover, the
height of the suction port of the pump should be less than 500mm.
