TECHNICAL INFORMATION
Please strictly follow instructions given in this catalogue for best performance and longer life of
pumps and motors
INSTALLATION NOTES
Before slarling the system on acontinuous basis, we suggest to adopt as follows simple precautions.
• Insure that pump rotation and motor or mover rotation are identical.
• Check for proper alignment of pump/mover shaft. It is important that the connection does not
create radial or axial load on the pump shaft
• Check if contact area between seal ring and shaft is clean, remove all dirt, chips and all foreign
bodies form flanges connecting inlet and delivery ports, dust could provoke quicker wear and
leakage.
• Ensure that intake and return pipes ends are always below fluid level and as far from each other
as possible.
• Fill the pump with fluid, and turn it by hand.
• Disconnect pump drain during startup to bleed air off the circuit.
• Always avoid or limit load at starting for pump longer life.
HYDRAULIC FLUIDS
Use mineral oil based hydraulic fluids having good antioxidant, anti-foaming (rapid de aeration),
anti-wear, anti-corrosion and lubricating properties, Fluids should also comply with DIN 51525 and
VDMA 24317 standards and gel through 11th stage of FZG test.
For the standard models, the temperature of the fluid should be between -10°C and +80°C.
Fluid kinematic viscosity ranges are the following:
allowed range
recommended range
value allowed at startup
6...500 cSt
10...100 cSt
...2000 cSt
INLET PRESSURE
www.yptius.com
Under standard working conditions, intake pipe pressure is lower than atmospheric pressure.
The operating inlet pressure should range between 0.7 and 3 bars (absolute).
-4-
FILTER RECOMMENDATION
It is widely known thal most pumps early failures are due to contaminated fluids. As a warranty cannot be issued for dirt related wear, we recommend a filter be used, which can reduce the degree of
contamination to a permissible dimension in terms of the size and concentration of dirt particles.
The filtering system shall always ensure contamination levels not exceeding the values indicated
below:

Hydraulic system pipes or hoses should not have changes of direction, sharp bends or sudden differences in cross-sections
They should not be loo long or out of proportion.
Pipe cross-section should be sized so that fluid velocity does not exceed recommended values.
Carefully consider the diameter reduction of the inlet and outlet pipes or hoses at the connection
point with fittings.
Reference values are the following:
ROTATION DIRECTION
Rotation direction of definition: when standing before the pump with driving shalt up with its projecting end towards the observer, the pump is rotating clockwise in case of right-hand rotation “D” .The
contrary will happen with left-hand pumps “S”, keeping the same point of view.
