A) Electric Motor
1. Roller cell furl pumps have a full copper commutator to insure the high flow/pressure requirements are maintained. This is great improvement over fuel pumps that have a layered or graphite commutator.
2. Every armature is fully load tested to insure that the manufactured part is free of shorts or open.
3. All commentators/armatures are double wrapped and soldered to prevent separation during severe loads.
B) Pump Section
1. Python uses Delrin material which is inserted into the fuel pump housing to protect roller bearings against wear and is effective against fuel debris.
Fuel Pump Testing
Pressure limiter (relief valve) is tested to insure satisfactory relief at high pressures to insure against internal pump failure. Non-return valve tested to insure maintenance of line pressure during fuel pump off time. All pumps are leak tested, surge tested, noise tested (decibel). All stage 1 fuel pumps are 10% above stock fuel pump flow rate. All universal HP733-515 pumps are offered @ 10% above stock flow rate or the 5 flow rates listed below.
