T7E Parker Denison Hydraulic Vane Pump core




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. Set the suction pressure at pump inlet port : Recommended inlet pressure is 0 to 35Kpa. 
3. Oil should be kept clean, pipes and tanks must be thoroughly cleaned; The cleanness level of oil 
should be within NSA12. 
4. Nomal pump operation(at rated conditions)is based on the use of SAE10W oil in the 38ºC to 82ºC 
range (or comparable viscosities) 
5. Check the inlet, outlet and direction of rotation before starting the pump. Turn the shaft of pump 
evenly and nimbly by hand after fixing the pump. At the time of first-starting ,if the pump does not 
immediately prime , air should be bled from the pump delivery line . 
6. When first put into use, the pump body and oil suction pipeline should be filled with oil, and the 
pump shall not be allowed to operate without oil. 
7. Do not start the pump when the outlet pressure is lower than the inlet pressure. This will cause work 
noise and blade instability. 
8. Cold start condition:When operating SAE10W oil in the 860 to 40 cSt range, the speed and 
pressure should be limited to 50% or less of their respective rated values until the system has 
warmed up. Extreme caution must be used when starting units when fluid viscosity are greater than 
860 cSt, Care should be exercised to warm up the entire system, including remote cylinders and 
motors. 
9. At high temperature, viscosities must not be less than 13cSt, Temperatures should not exceed 99ºC 
because the expectancy of cartridge kite and ela
stomers will decrease
