Abstract
PT. PJB Unit Pembangkitan Gresik atau disingkat PT. PJB UP Gresik merupakan perusahaan yang bergerak dibidang pembangkitan listrik yang mempunyai peran menghasilkan energi listrik dan menyalurkan ke berbagai daerah dimulai dari Pulau Jawa, Pulau Madura, sampai Pulau Bali. Pembangkit Listrik Tenaga Gas & Uap (PLTGU) adalah salah satu jenis pembangkit yang ada di PT. PJB UP Gresik. Pembangkit tersebut memiliki tiga blok yang mana setiap blok memiliki tiga turbin gas dan satu turbin uap.
Salah satu jenis komponen yang ada pada Pembangkit Listrik Tenaga Gas & Uap (PLTGU) adalah Low Pressure Boiler Feed Pump. Komponen ini berfungsi untuk mendistribusikan air demin (demineralized water) dari deaerator menuju HRSG (Heat Recovery Steam Generator). Untuk bisa mendistribusikan air demin sesuai dengan kebutuhan proses produksi, maka diperlukan kriteria pemilihan pompa yang tepat.
Pada penulisan Tugas Akhir ini didapatkan beberapa perhitungan ulang instalasi Low Pressure Boiler Feed Pump yang pada akhirnya digunakan sebagai kriteria pemilihan pompa yaitu kapasitas operasi tertinggi sebesar 83,34 m3/h dengan head efektif instalasi sebesar 138,109 m, serta didapatkan NPSHA sebesar 22,4834 m. Sehingga dari hasil beberapa perhitungan tersebut, maka dapat dipilih pompa sentrifugal single stage buatan Ensival Moret serial no. CN80-32 dengan jenis low- speed impeller.

PT. PJB Generation Unit Gresik or abbreviated as PT. PJB
UP Gresik is a company which move in electricity generation that has the role of generating el
ectrical energy and distribute to various regions are started from Java Island, Madura Island,
until Bali Island. Gas & Steam Power Plant (PLTGU) is one type of power plants in PT. PJB UP Gresik. It has three blocks in which each block has three gas turbines and one steam turbine.One type of components that exist in Gas & Steam Power Plant (PLTGU) i
s Low Pressure Boiler Feed Pump. This
components serve to distribute demineralized water from the deaerator to the HRSG (Heat Recovery Steam Generator). To be able to distribute demineralized water in accordance with the needs of the production process, it is necessary to select the
appropriate pump selection criteria. At the writing of this Final Project has got some
recalculation of installation of Low Pressure Boiler Feed Pump which in the end
is used as criteria of pump selection that is the
highest ope rating capacity equal to 83,34 m3 / h with effective head of installation equal to 138,109 m, and has got NPSH A equal to 22,4834 m . So from that results, it can be selected single stage
centrifugal pump made by Ensival Moret serial no. CN80
-32 with low-speed impeller type.
