2.0 INSTALLING THE MOTOR
TDI T30-M Motors feature a turbine type air
Motor that does not require lubrication in the
supply air
.
If a vane-type Motor is being replaced by a
TDI turbine type Motor, TDI recommends
removal of in-line or mist type lubricators to
minimize Motor supply flow restriction,
eliminate oily exhaust residue and reduce
maintenance.
2.1 PROPER INSTALLATION & SET-UP
WARNING
Do not operate this Motor unless it is properly
connected to a load (see below).
Motor & oil pump must be installed in a
location that prevents unloaded or under-
loaded operation.
T30-M Lube Pump Motor w/optional exhaust muffler
There are two main causes for the oil pump to become
unloaded or under-loaded:
1) Cavitation
- air in the oil suction line to the pump.
This can be prevented by insuring the oil supply
(suction) line to the pump inlet, is below the oil sump
level of the equipment/engine. This is referred to as a
“flooded” location, as it insures oil will always be
present at the pumps suction port. This is
VERY
IMPORTANT
when up-fitting a TDI pump package that
uses the T30-M motor, or installing a T30-M motor
replacement on an existing oil pump. Take steps
necessary to prevent accumulation of excessive air in
the oil system. Utilize check valves and vent lines in
accordance with equipment/engine manufacturer’s
guidelines.
2) Excessive Motor Output
Excessive Motor (Horsepower) results in pump over-
speed. Excessive HP output will drive the mechanical
oil pump to a speed higher than recommended (most
are rated at 1200-1750 RPM for maximum life).
Oil pump over-speed does not always produce
excessive or higher (indicated) oil pressures (on a
panel or gauge) because most machines and/or oil
pumps have a pressure bypass. Even pumps with a
pressure bypass, if operated at excessive speed, may
fail bearings and/or seals prematurely.
Adjusting T30-M Motor output is accomplished
simply
by reducing
(or increasing if needed) the dynamic
motor supply air/gas pressure. Matching the motor
output speed
to the same optimum range
as that of the
oil pump (1200-1750 RPM) will provide maximum T30-
M Motor life
2.2 SUPPLY & EXHAUST LINE
INSTALLATION
WARNING
Be sure to either bleed the pressurized air reservoir
and/or safety the system such as closing all air/gas
supply valves prior to installing Motor or a new
supply line.
The T30-M Motors come standard with a 1.0 inch NPT
female pipe thread connection at the inlet. A 1.5 inch
or 2.0” exhaust adapter is standard. Supplied adapters
are sealed with Viton O-rings.
The Motor supply line consists of the line from the
air/gas supply source (via a pressure regulator when
necessary) through filters, manual and/or automatic
relay valves to the Motor
inlet.
The exhaust line consists of the line from the Motor
exhaust to a “safe” location. Turbine exhaust (gas) is
typically plumbed away from the engine area.
Hard piping may be used on supply/exhaust lines. A
section of flexible tubing (gas approved where
required) is recommended, between Motor
inlet/exhaust outlets, to the hard piping. This can
prevent leaks or “wobble” out due to piping weight &
vibration and ease of field maintenance/replacement of
