Applications
The PF53481-120 is designed for line maintenance technicians, A&P mechanics, and MRO facilities servicing commercial aircraft turbine engines that require Mobil Jet II lubricant. Its portable hand-pump design makes it ideal for ramp operations, hangar use, and remote servicing locations where powered equipment is impractical. Every dispense is filtered to 3 microns, safeguarding engine bearings and oil system components against particulate contamination that can lead to premature wear or AOG events.
Service & Support
Regular filter element changes every 3-4 months (or sooner if pumping resistance increases) keep the unit performing at spec. Malabar offers the PF5-49PK repair parts kit containing the hose assembly, filter element, pump gasket, O-rings, spring, pins, and fasteners needed for routine pump rebuilds — recommended stocking inventory for any fleet using this dispenser.
