GENERAL INFORMATION

swash-plate system, for closed loop hydro-
static transmissions, that offer the best po-
wer to weight ratio because of new innovati-
ve design and production technologies.
speed and is continuously variable accor-
ding to the angle of the swash-plate from
"0" to maximum displacement.
with a boost pump, “gerotor” type of new
design and high efficiency to keep the cir-
cuit pressurised, to compensate the oil le-
akages of the hydrostatic transmission, to
avoid cavitation of the piston pump and to
supply low pressure oil flow to the remote
controls of the pumps and of the hydraulic
transmission (max 3 MPa).
controls are available for remote regula-
tion of the pump displacement by means of
hydraulic or electric joysticks.
Pumps are also available with integrated
sensors for the control of the speed, of the
angular position of the swash-plate and
of the oil pressure. These sensors allow a
complete remote control of the pump by an
external electronic system.
The mounting flange is according to
SAE-B 2 bolt, the through-drive is according
SAE-A 2 bolt.
Different other optionals are available for
the TPV-TPVTC 1500 pumps.

Directive 98/37/EC, therefore have been

The housing and the distributor cover of the
TPV-TPVTC 1500 pumps are made in cast
iron.
The flow rate is proportional to the rotation
speed and the displacement is continuously
variable. It increases as the swash-plate an-
gle moves from "0" to maximum position.
If the swash-plate is positioned out of the neu-
tral position, the flow respectively follows one
of the two directions.

Pressure
Continuous pressure: is the average pres-
sure for continuous work, which must not
be exceeded, to ensure a correct and long
lasting service of the pump.
Maximum pressure: is the maximum allow-
able pressure for short periods and must
never be exceeded.
Speed
Continuous work speed: is the maximum
recommended speed for continuous opera-
tion of the pump under full load.
Maximum speed: is the maximum permis-
sible speed for the pump for short periods
and not fully loaded. The use of the pump
with this speed can reduce the life and cau-
se a loss of power or of the hydrostatic bra-
king capacity.
Caution
Any damage caused to the pump can reduce
or eliminate the hydrostatic braking capacity.
It is therefore necessary to provide an auxi-
liary braking system capable of stopping and
supporting the weight of the complete machi-
ne, in the event of loss of hydrostatic power.

The pump displacement variation is obtained
by adjusting the pressure on P1 and P2 servo
control ports by means of a hydraulic propor-
tional joystick (with integrated pressure redu-
cing valves).
The servo control oil supply can be obtained
by taking pressure from the boost pump (G
port), see page 18.
The servo control return time can be adjusted
by inserting a restrictor on the joystick supply
line (0,5 ÷1,2 mm).
The servo control operation curve, in both di-
rections, goes from 0,4 to 1,8 MPa (tolerance
(± 5 %).
The adjusting curve of the hydraulic joystick
has to be a little wider (0,3 ÷ 1,9 MPa).

The pump displacement variation is obtained
by adjusting the pressure on P1 and P2 servo
control ports by means of a hydraulic propor-
tional joystick (with integrated pressure redu-
cing valves).
The servo control oil supply can be obtained
by taking pressure from the boost pump (G
port), see page 18.
The servo control return time can be adjusted
by inserting a restrictor on the joystick supply
line (0,5 ÷ 1,2 mm).
The servo control operation curve, in both di-
rections, goes from 0,4 to 1,8 MPa (tolerance
(± 5 %).
The adjusting curve of the hydraulic joystick
has to be a little higher (0,3 ÷ 1,9 MPa).

The pump displacement variation is obtained
by adjusting the pressure on P1-P2-P3-P4
servo control ports by means of a hydraulic
proportional joystick (with integrated pressure
reducing valves).
The servo control oil supply can be obtained
by taking pressure from the boost pump (G
port), see page 58.
The servo control return time can be adjusted
by inserting a restrictor on the joystick supply
line (0,5 ÷ 1,2 mm).
The servo control operation curve, in both di-
rections, goes from 0,4 to 1,8 MPa (tolerance
(± 5 %).
The adjusting curve of the hydraulic joystick
has to be a little wider (0,3 ÷ 1,9 MPa).

TROUBLES CAUSE REMEDY
High noise level
Too high rotation speed of the pump. Reduce pump rotation speed.
Wrong rotation direction. Check the rotation direction of the pump.
Obstruction in suction line - air in the
suction line - wrong oil viscosity -
diameter of suction line too small.
Check oil type and viscosity. Check
internal diameter of suction line.
Remove restrictions. Check oil level of
reservoir. Eliminate air intake.
Not correct connection of the pump.
Not correct diameter of pipes/hoses.
Check the pump connections and the pipe/
hose diameters according to notes.
Vibrations of relief valves .
Check the inlet suction line - Check and
replace relief valves.
Internal parts worn out. Check and replace.
Wrong pump connection to the prime
mover.
Check connections and rotation direction.
Too low rotation speed of the pump. Increase the pump rotation speed.
Low flow rate
Obstructions in the suction line - wrong
viscosity.
Check oil type and viscosity. Check
internal diameter of suction line.
Remove restrictions. Check oil level of
reservoir. Eliminate air intake.
Low remote control pressure. Check and adjust.
High internal leakage. Check the case drain flow.
Low rotation speed of the pump. Increase speed of the pump.
Instable or low pressure
Obstruction of suction line - air in the
suction line - wrong oil viscosity -
diameter of suction line too small.
Check oil type and viscosity. Check
internal diameter of suction line.
Remove restrictions. Check oil level of
reservoir. Eliminate air intake.
Vibration of relief valves.
Check the inlet suction line. Check and
replace relief valves.
Internal parts worn out. Check and replace.
Over heating
High oil temperature at suction inlet. Check the cooling system.
Internal parts worn out. Check - replace.
Wrong setting of relief valves. Check - adjust the setting of relief valves.
