Unique Core Product Competitive Advantages
-
Classic PT Pressure-Time Fuel Supply Structure For Stable Constant PowerAdopts mature PT mechanical fuel supply principle, matched with EFC electronic speed control valve. It maintains steady fuel delivery to stabilize generator output frequency, avoid power fluctuation during peak electricity consumption and marine wave vibration.
-
Heat-Treated Precision Plunger Assembly For Low-Quality Fuel AdaptabilityInternal plunger and metering valve adopt deep quenching wear-resistant alloy, stronger tolerance to impure diesel, heavy sulfur fuel and marine fuel with moisture. Thickened cast steel pump housing withstands long-term high-temperature working environment without deformation.
-
Complete Dual Performance Bench Inspection Before DeliveryEvery PT pump undergoes idle speed calibration, full-load fuel supply test, solenoid cut-off test and overall sealing inspection on dedicated K series PT test bench. Each unit calibrated to factory standard fuel curve to guarantee uniform cylinder fuel supply.
-
Integrated OEM Matching EFC Governor & Fuel Shutoff SolenoidEquipped with same specification electronic governor and fuel cut solenoid as original pump, perfectly match old machine control circuit, no wiring rework, no abnormal shutdown fault during equipment operation.
-
Two Quality Grades For Different Equipment Service CyclesWe supply full brand-new PT pumps with all brand-new internal precision components for 24/7 continuous generator & marine operation, and professionally remanufactured pumps with all worn core parts replaced & recalibrated for periodic mining equipment maintenance with lower cost.
