ULTRALEGGERI

Mechanical fuel pump for Rotax 914-912

 

MECHANICAL GASOLINE FUEL PUMP FOR ROTAX® 914 TURBO

 

Flygas produce Mechanical Fuel Pumps from many years, and from now will be available at all the Rotax 914 turbocharged or 912Ul-ULS Supercharged, instead at the electrical Pierburg 1 bar pump.

Easy and reliable installation on your Rotax 914 flywheel without  modify request so simple installation, this fuel pump it’s supplied with all parts necessary included installation booklet with picture step by step.

After installed, it will can supply gasoline at 1bar of pressure (until 3bar in a case of E.F.I. installed)
This full parts ready to install Fuel Pump is lightweight (only 680Grams, just basically same weight of electrical Pierburg Fuel Pump included wires and switch.)

Technical Detail:
  • Total weight installed 680 grams (about one mechanical fuel pump)
  • Maximum pressure reached 14Bar
  • Maximum continuative pressure 3Bar
  • Maximum Speed 7000 RPM
  • Maximum draft depth is 900mm
  • Pressure regulator of fuel, is required on the plan
  • Flow of gasoline in function of RPM and Pressure

 

Data Sheet

Advantages:
  1. Fuel flow independent of 12 volts
  2. Much reliability
  3. Electrical power save
  4. Fired safety
  5. Fuel plant more easy/cleared

 

  1. The first advantage that you should replace one of your two electric fuel pump with this flygas mechanic is being no longer dependent on the 12 volt voltage as this electronic rectifier would be broken, in just a few minutes the voltage would drop and the pump would stop working (depending on the size and state of your battery)
  2. More Reliability: All electric pumps have very little driving torque, so if it runs too small in dirt, it would be stopped. To avoid this, all electric pumps are equipped with a very low input filter, fine mesh with a small surface. This filter CAN’T TO BE EXCHANGEABLE, AND IN ANY CASE create in some conditions, the bubbles of air inside of gasoline sucked because gasoline is in depression; These inevitable bubbles contribute to deterioration of the pump. With our mechanical pump the torque is very high, so it will never lock, so it will not be a fine mesh filter in the input. In the case of polluted, dirty gas (which, of course, to avoid), the pump may eventually deteriorate, the maximum flow rate and maximum pressure will drop over time, but you will notice the varying pressure values. It should be said that we have, in this regard, done a pump that brings more than 160lt per hour, and is born to created 14Bar of pressure! ;against the current Pierburg electric that brings 100lt / h (hence wide margin of deterioration over time)

3 . Electrical power saving for Other Services: Let’s remember that an electric pump absorbs almost 6 amphs, and there are two transformations of power from mechanics to electrical, and again from electrical to mechanical again

  1. Greater cleaning of the plant, a switch and wires less, less pipes passing through the engine in hot areas   that means less risk of Vapor-lock
  2. Increased fire safety: If engine is “0” rpm the flow are “0”Liters! And also, located behind the flywheel, it is located in a protected area

Finally, we want remember you, All aviation and racing engines have always used and used today , mechanical fuel pumps.

 

Components of the kit:
  • Mechanical Fuel Pump completed Assembled and tested
  • All bracket necessary with screw, pin, extc.
  • Joint Transmission Driver

 

Intercooler for Rotax914

special intercooler for rotax 914 instead of original airbox

Main features for Rotax 914 Turbo
1. Increase and constant maintenance of the power due to the lower compressed air temperature at engine inlet;
2. Installed instead of the original Airbox, without waste space in the engine compartment
3. Reduction of the risk cutting power on Rotax 914. The lowest air temperatures in carburetors input coincides with an important reduction in the risk of intervention of the TCU control unit. This unit, over the 82 ° C air, open waste-gate valve and discharge boost pressure, avoiding damage to the engine but losing most of the power supplied.
4. Better distribution of mass air to the engine with cylinder banks relative balance without the need to be fitted on the carburetors different main jets between them
5. Assembly “Aircooler” personalized according to your space and on yours overall limits

 

GAS 252 engine

GAS 252 engine for ultralight airplane and trike

GAS 252 is engine for ultralight airplane and trike. The two cylinders boxer weight only 57 kg (125 pound) develops a power of 70.7hp (52kw) and has a very low fuel consumption in cruise speed, only 7,5 lt\hr (1.98 Gal\hr) @4500rpm.

 

 

Technical characteristics
  • A modern, light and compact SUPERCHARGER, guarantees power, low fuel consumption and exhaust temperature 200°C (392°F) less respect an engines with turbocharger.
  • The air cooler is guaranteed by an efficient finning system
  • An extremely efficient dry-sump system assures the emptying of the sump, and most of all a huge quantity of oil in a continuous recycle at a constant pressure of 4-5 bar.
  • Totally controlled by an electronic fuel injection and ignition system of last generation. Fundamentally important is the system of down-load data that transfers all data from the E.C.U. to the Dash-board through Can-Line.This will allow you to download the data, and with a simple operation, to send them to us via e-mail. FlyGas will analyze the data and send you the report.
