Intisari Sistem hidrolik adalah sistem yang bekerja sebagai transfer energi dengan menggunakan cairan sebagai mediator. Sistem hidrolik digunakan untuk mengangkat bak. Pompa roda gigi digunakan untuk memindahkan bak belakang hydrolically. Tujuan dari penelitian ini untuk mengetahui laju aliran, headpompa, kecepatan pompa dan motor, rasio transmisi, daya pompa dan motor serta mengetahui kekentalan minyak yang digunakan. Dalam penelitian ini, penulis melakukan pengujian pompa roda gigi, Sesuai yang telah dirancang sebelumnya. Peralatan uji motor 3 phase 2 tiang, pompa roda gigi, alat uji, selang, dioperasikan pilot katup, tekanan pengukur motor inverter, handspump, tachometer, 40 liter Turalik 52 minyak, dll. Hasil setelah dihitung antara lain laju aliran tertinggi di dunia 75 liter / menit, dan laju alir terendah adalah 23,4 liter / menit. Displacement tertinggi adalah 53,7 cc / rev. Tertinggi efisiensi total 59,13 %. Daya tertinggi motor 30.2 HP. Daya tertinggi pompa 12,1 HP. Head pompa tertinggi adalah 41,83 meter.

Abstract Hydrolic system is a system which work as an energy transfer with using fluids as mediator. Hydrolic system is used for lifting the tailgate. Gear pump is used to move the tailgate hydrolically . The purpose of this research is to know flow rate, head pump system, speed of pump and motor, transmition ratio, power both of pump and motor and the last is to know density of oil used. In this research, the writer did testing gear pump according designed which had been made before. Test equipments are Motor 3 phase 2 pole, gear pump, testing instrument, hoses, pilot operated relief valve, pressure gage,motor inverter, handspump, tachometer, 40 litres Turalik 52 oil, e.t.c. The results after calculating are highest flow rate’s 75 litres/min, and lowest flow rate is 23.4 litres/min. Highest displacement is 53.7 cc/rev. The highest efficiency total is 59,13. The highest power of motor is 30.2 HP. The highest power of pump is 12.1 HP. The highest head pump is 41.83 metre. Keywords: pump, gearpump, performance
