Petroleum base anti-wear R & O fluids (covered by Parker Denison HF-0
and HF-2 specifications).
Maximum catalogue ratings and performance data are based on opera-
tion with these fluids.
The use of fluids other than petroleum base anti-wear R & O fluids re-
quires that the maximum ratings of the motor will be reduced. In some
cases, the minimum replenishment pressure must be increased.
HF-1 : non antiwear petroleum base.
HF-4 : water glycols.
HF-5 : synthetic fluids.
Max. pressure : 210 bar (3000 PSI) (HF-1, HF-4, HF-5)
Max. speed : 1500 RPM (HF-4, HF-5)
Max. (cold start, low speed and pressure) 2000 mm

For cold starts, the motor should operate at low speed and pressure until
fluid warms up to an acceptable viscosity for full power operation.
90 min.
Higher values extend the range of operating temperatures and lifetime.
Max. fluid temperature (HF-0, HF-1 & HF-2) + 100° C (+212 ° F)
Min. fluid temperature (HF-0, HF-1 & HF-2) - 18° C ( - 0.4 ° F)
The fluid must be cleaned before and during operation to maintain a
contamination level of NAS 1638 class 8 (or ISO 19/17/14) or better.
Filters with 25 micron (or better, ß10
≥
100) nominal ratings may be ade-
quate but do not guarantee the required cleanliness levels.
Maximum acceptable content of water :
• 0,10 % for mineral base fluids.
• 0,05 % for synthetic fluids, crankcase oils, biodegradable fluids.
If the amount of water is higher, then it must be drained off the circuit.
For standard applications: with mineral oil and fluid temperature less than
+ 90° C (+ 194° F).
S1 seal temperature range : - 40° C to + 107° C (- 40 to + 225° F).
Use this seal type with fire resistant fluids and/or fluid temperature hi-
gher than + 90° C (+ 194° F).
S5 seal temperature range : - 29° C to + 204° C (-20 to + 400° F).

+ Anti-starve
uni-rotational M5AS - M5ASF option : Anti-starve check valve
An anti-starve check valve can be screwed directly onto the B port of the uni-rotational
motors, to ensure the minimum replenishment pressure during deceleration phases
of high inertia systems (i.e. fan drive).
