A10VO PISTON PUMP MANUAL-MODULE 3A
SPECIFICATIONS
Pressure
The pressure range for the standard models used as outlined under standard models is 4,100
PSI maximum.
R.P.M .
NOTE:
This figure is dependant on inlet conditions ensure you follow recommended installation
guidelines as per commissioning instructions.
Maximum speed (flooded suction)
P/N 130985 (A10V028) = 3000 rpm
P/N 130272, 124691 and 117556 (A10V045) = 2600 rpm
P/N 103616 and 149312 (A10V071) = 2200 rpm
Case
Drain
Ensure pump mounted with case drain at highest to location to ensure pump prime is not lost and
remains adequately lubricated. Maximum permissible pressure of the case drain can be 7 PSI
(0.5 bar) maximum, higher than inlet pressure or suction pressure. Yet case pressure no higher
than 30 PSI (2 bar) absolute.
OPERATING CONDITIONS
Operating Viscosity
Operating viscosity range: For optimum efficiency and pump life, we recommend that the
operating viscosity (at operating temperature) be selected in the range of
√
opt = optimum
operating viscosity 81...167 SUS (16...36 mm2/s) taking into consideration the reservoir
temperature range.
Viscosity limits: The following values are valid for extreme operating conditions of short duration.
√
min = 60 SUS (10 mm2/s) for short periods at max. permissible drainage oil temperature of
94º F (90ºC)
√
max = 4635 SUS (1000 mm2/s) for short periods upon cold start.
Recommended Filtration
In order to guarantee reliable function, both return and pressure filters should have 10 micron min
Inlet Conditions
(
Suction Line)
The suction line, pipe or hose, should be as short and straight as possible. The pipe section
should be such that the negative pressure at the suction port never falls below 11.6PSI (abs.) (0,8
bar) and never rises above 29PSI (abs.) (2 bar). Make sure connection points are airtight and that
hoses are sufficiently pressure resistant against external air pressure. Use plastic hoses with
supporting mesh. Make sure there are no kinks in the hose when installing.
