Abstract

Dalam operasinya, pompa harus dapat memenuhi head yang diperlukan oleh sistem pipa. Head statis pompa harus ditentukan dengan mempertimbangkan karakteristik pompa apabila permukaan air berubah-ubah. Oleh karena itu dibuatlah tugas akhir Rancang Bangun Alat Uji Head Statis Pompa pada Tekanan 1,5 Bar. Tujuan dari pembuatan alat ini adalah untuk mengetahui karakteristik sistem pompa dengan menghitung : head total pompa, head sistem dengan metode ( perhitungan ) dan ( pengukuran ) dan efisiensi pompa,yaitu dengan cara pengaturan laju aliran pompa melalui pembukaan katup dan pengaturan frekuensi melalui inverter. Hasil pengujian head statis pompa menggunakan fluida air pada tekanan dalam tangki 1,5 bar diperoleh hasil sebagai berikut : head total pompa pada debit tertinggi sebesar 16,3 m dan head total pompa pada debit terendah sebesar 26,81 m. Sedangkan pada head sistem ( Metode Perhitungan ) pada debit tertinggi sebesar 16,7 m dan pada debit terendah sebesar 16,58 m dan head sistem ( metode pengukuran ) pada debit tertinggi sebesar16,53 m dan pada debit terendah sebesar16,53 , maka hasil pengujian didapat titik kerja pompa pada laju aliran 16,02 LPM ( Liter Per Menit ) dengan head pompa 16,74 m. Kata kunci : pompa sentrifugal, head statis, head sistem, head total pompa, laju aliran. In operation, the pump must be able to meet the head required by the system piping. Static head pump must be determined by considering the characteristics of the pump when the water level changes. Therefore made final project "Design of Static Head Test Equipment Pump at Pressure of 1.5 Bar. The purpose of this tool is to determine the characteristics of the pump system by calculating: total pump head, head system with the method (calculation) and (measurement) and the efficiency of the pump, that is by setting the pump flow rate through the valve opening and frequency setting through an inverter. Test results using the pump static head of fluid in a tank of water at a pressure of 1.5 bar the results are as follows: total head of the pump at the highest discharge of 16.3 m and a total head of the pump at the lowest discharge of 26.81 m. While the head system (calculation method) at the highest discharge of 16.7 m and the lowest at 16.58 m discharge and head system (method of measurement) at the highest discharge 16,53 m and the lowest discharge sebesar16,53, the test results pump working point obtained at a flow rate 16.02 LPM (liters Per Minute) with 16.74 m pump head. Keywords : centrifugal pump, static head, system head, pump total head, flow rate.
